This page shows what was measured, who it was measured in, and what that does not settle.

What Prednisolone does in the body

Your adrenal glands make a hormone called cortisol that tells cells to stop producing inflammatory proteins.

Prednisolone is a manufactured version of that hormone, altered so it lasts longer and acts more on inflammation than on salt and water balance. Once inside a cell it binds a receptor that travels into the nucleus, settles on the DNA, and silences the genes that make the signals of inflammation. Because that receptor sits in nearly every cell in the body, the drug cannot be aimed: the same switch that quietens a swollen joint also thins bone, raises blood sugar and blunts the response to infection.

Why people take it. Inflammation and overactive immune responses, across a very wide range of conditions

What happened in people

Complete facial recovery in 83.0% against 63.6% at three months in Bell’s palsy, P<0.001, in a placebo-controlled factorial trial

Source-linked record

Where this came from

A person wrote this into the record with the study named beside it. No reviewer has signed it off.

The recorded finding that sits closest to something a person would notice. Written into the record, not signed off, and it carries no population or interval.

The limit that matters most

That the standard steroid equivalence table transfers harm as well as potency — it was built from anti-inflammatory bioassay, and adrenal suppression follows half-life instead

Where it acts
The cytoplasm and then the nucleus of almost every nucleated cell in the body — the glucocorticoid receptor is not tissue-restricted, and that is the whole story of this drug
Kind of result
The kind of result is not recorded
Supervision
Professional supervision is normally required. A regulator classifies this substance in a way that restricts how it is supplied.

Words this page uses

Four words worth knowing first

Chosen from what this page shows, with each one explained before the word it depends on.

Stand-in result

A stand-in result is a number measured because the real result takes too long.

A picture of it, and where the picture fails

It is like judging a journey by the speedometer rather than by arriving.

Where that stops being true. Speed does predict arrival. Many stand-in results do not predict the real one.

What people get wrong. A stand-in result is often reported as the result itself.

A surrogate endpoint substituted for a clinical endpoint, valid only where the substitution has been shown to hold.

Randomisation

Randomisation means chance decides who gets which treatment.

A picture of it, and where the picture fails

It is like a coin toss deciding the groups.

Where that stops being true. A coin toss is fair once. Fairness here comes from doing it for everyone.

What people get wrong. It is thought to make groups identical. It makes them similar on average, including on things nobody measured.

Allocation of participants to arms by a chance process, so that unmeasured factors are balanced in expectation.

Confidence interval

A confidence interval is the range the true answer is likely to sit in.

A picture of it, and where the picture fails

It is like a weather forecast giving a range rather than one number.

Where that stops being true. A forecast range covers tomorrow. This one covers what the study could resolve.

What people get wrong. The middle number is read as the answer. A range crossing zero means no change is still possible.

An interval estimate that would contain the true parameter in a stated proportion of repeated studies.

Pathway

A pathway is a chain of steps inside a cell, each one setting off the next.

A picture of it, and where the picture fails

A pathway is like a row of dominoes.

Where that stops being true. Dominoes fall one way. Pathways loop back and can switch themselves off.

What people get wrong. Changing one step is read as changing the outcome. Other steps often absorb it.

An ordered series of molecular interactions producing a defined cellular change.

How close this is to real life

The top step is something a person would feel or care about. The bottom is a guess from software. Filled steps are where evidence exists for this substance.

  1. Living longer, or avoiding a major event Evidence recorded. Death, a heart attack, a stroke, a hospital stay.14 registered measures of this kind. No reviewed result.
  2. What a body can do day to day No evidence recorded. Walking, dressing, breathing, recovering.No registered study measures this.
  3. Measured performance No evidence recorded. How much was lifted, how far was run, how fast.No registered study measures this.
  4. Symptoms and quality of life No evidence recorded. Pain, tiredness, mood, sleep, as the person rated it.No registered study measures this.
  5. A number that stands in for health Evidence recorded. Cholesterol, blood sugar, bone density. A stand-in, not the thing itself.1 registered measure of this kind.
  6. A step measured inside a person Evidence recorded. Something measured in human tissue or human cells.A human record sits on the stored organism ladder.
  7. Animals Evidence recorded. Mice, rats, dogs. Useful for ideas, not proof about people.Stored records in Mouse, Rat, Dog. A result in animals says what to test next. It does not say what happens in people.
  8. Cells in a dish Evidence recorded. Cells or chemistry on a bench, far from a whole body.Stored mechanism abstracts describe steps measured in cells or tissue.
  9. A guess from software No evidence recorded. Nobody measured it. RNAWiki never publishes one as a finding.RNAWiki stores no prediction for this record. Software can suggest a link. RNAWiki does not publish one as a finding.

Higher on these steps means closer to something a person would feel. It does not mean better done.

What it changes in the bodyRead from sources, not yet reviewed

The path through the body

From what a person takes to what changes. A solid line is a step measured in people. A dashed line is a step nobody has measured that way.

  1. Start

    Prednisolone

    What a person takes: Oral solution, oral tablet, orally disintegrating tablet, ophthalmic suspension and emulsion, and injectable sodium phosphate and acetate salts.

    The measurement behind this step

    Absorbed rapidly and completely from the gut, with peak concentrations within one to two hours. The sodium phosphate salt is water-soluble and used for injection and for oral solution; the acetate salt is a poorly soluble depot for intra-articular and ophthalmic use. Ophthalmic formulations exist because the eye is one of the few places a glucocorticoid can be delivered locally at high concentration with limited systemic exposure.

  2. Getting in

    Swallowed or injected, and already active

    Unlike its close relative prednisone, prednisolone does not need the liver to switch it on. It is the working form from the moment it is absorbed, which is why it is preferred when liver function cannot be relied on.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Prednisolone is the 11-beta-hydroxy species. Prednisone is its 11-keto prodrug and has no intrinsic receptor affinity until 11-beta-hydroxysteroid dehydrogenase type 1, largely hepatic, reduces it. Prednisolone is extensively protein bound, principally to transcortin at low concentrations and to albumin once transcortin saturates, which gives it non-linear kinetics across the clinical range.

  3. Reaching the cell

    It walks straight through the cell membrane

    Steroids are greasy enough to cross a cell membrane without a transporter or a receptor on the surface. There is no gate to select which cells receive the drug, which is the reason its effects are body-wide.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Passive diffusion across the lipid bilayer, driven by the logP of about 1.9 held on this record. Intracellular access is modulated rather than gated: the efflux pump P-glycoprotein exports some glucocorticoids, and 11-beta-hydroxysteroid dehydrogenase type 2 in kidney and colon inactivates cortisol locally to protect the mineralocorticoid receptor — a protection prednisolone partly evades.

  4. What it acts on

    It frees a receptor that was being held in reserve

    Waiting in the cytoplasm is a receptor clamped in a complex of chaperone proteins. When prednisolone binds, the clamp releases and the receptor is free to move.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    The unliganded glucocorticoid receptor (NR3C1) is held in an inactive multiprotein complex with HSP90, HSP70, p23 and an immunophilin, usually FKBP51. Ligand binding triggers exchange of FKBP51 for FKBP52, which recruits dynein and licenses nuclear import through the receptor’s two nuclear localisation signals.

  5. The change it makes

    The receptor enters the nucleus and rewrites which genes are read

    The freed receptor travels into the nucleus and does two things at once: it switches some genes on by landing directly on the DNA, and it switches others off by grabbing the proteins that would have turned them on.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Homodimers bind glucocorticoid response elements to transactivate genes including TSC22D3 (GILZ), NFKBIA, DUSP1 and ANXA1. Monomeric receptor transrepresses by tethering to NF-kappaB p65 and to AP-1, and by recruiting histone deacetylase 2 to their promoters, suppressing IL-1, IL-2, IL-6, TNF-alpha, COX-2 and inducible nitric oxide synthase. Transactivation is thought to carry most of the metabolic harm and transrepression most of the anti-inflammatory benefit, which is the premise of the dissociated-steroid programmes that have so far produced no marketed drug.

  6. What that does for a person

    Inflammation falls within hours, and keeps falling for days

    Because the effect works through gene transcription rather than by blocking a single molecule, it takes a few hours to appear and then persists after the drug itself has been cleared.

    Measured in people. Written by a person from the study named beside the step. Not signed off as a reviewed claim.

    The measurement behind this step

    The plasma half-life is 2 to 4 hours but the biological half-life is 12 to 36 hours, because the endpoint is a changed transcriptional programme rather than an occupied receptor. Measured downstream effects include lymphocyte redistribution out of the circulation within hours, suppressed eosinophil counts, reduced capillary permeability and inhibited phospholipase A2 activity through induced annexin A1.

  7. What that does for a person

    The same receptor is in bone, muscle, pancreas and the adrenal feedback loop

    There is no version of this mechanism that only affects the inflamed tissue. The receptor sits in bone-building cells, in muscle, in the liver and in the gland that makes your own cortisol, and the drug acts on all of them at once.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Glucocorticoid receptor activation in osteoblasts suppresses Wnt signalling and increases osteoclast lifespan, in skeletal muscle induces atrophy through FOXO and myostatin, in liver induces gluconeogenic enzymes, and at the pituitary suppresses proopiomelanocortin transcription and therefore ACTH, causing adrenal atrophy. Fracture risk rises within 3 to 6 months of starting, and hypothalamic-pituitary-adrenal recovery after a prolonged course can take months.

No suggested links are held for this record, so nothing is hidden from this path.

What we know
The record describes 6 steps from taking it to an effect in a person.
How we know it
Each step names the study behind it in the technical detail beside it.
What this does not prove
A change inside the body is a reason to look. It is not a result in a person.
Why it matters
A reader can see exactly where the chain stops being measured in people.
What we still do not know
No reviewed claim binds any of these steps to a named population.

What it would be like to takeRead from sources, not yet reviewed

Felt, measured, or meaningful

Three different things that get called the same word. Registered studies measured all three, and mixing them is how a blood test becomes a health claim.

Felt

Things a person could notice without a test.

No registered study measured anything of this kind.

Measured

Things only a test, a scale or a device shows.

  • creatinine clearance rate

Meaningful

Things that change how a life goes, not only a number.

  • event free survival
  • event free survival after first randomization
  • disease free survival after second and third randomization
  • event free survival at 3 4 years after diagnosis
  • disease free survival by routine imaging
  • rate of complete remission
  • disease free survival
  • remission rate
  • remission duration
  • overall survival

and 4 more.

A registered study says what someone planned to measure. It does not say what they found. A number moving is not the same as a life going better. The two are shown apart here.

Felt, but not shown to help. A person notices a change. No study showed it leads anywhere good.

Measured, but not felt. A number moves. The person notices nothing. Both can be true.

Measured, but not shown to matter. A number moves in the good direction. Nobody showed that lives went better.

Matters, but takes years. The result that counts may take longer than anyone would keep watching.

  • renal function
  • an acr20 response
  • glomerular filtration rate from baseline to month 12
  • proteinuria

Were people like you studied?

RNAWiki cannot tell whether a study fits you. It can show who was in it, and where the result stops carrying.

Who was studied

People similar to this profile were included.

  • People with asthma flares, inflammatory bowel disease, rheumatoid arthritis, nephrotic syndrome, autoimmune skin disease, transplant rejection, some cancers, and adrenal insufficiency, where it is replacing a hormone rather than suppressing anything.

Who is missing from the studies

  • Which groups were under-represented in the studies has not been recorded for this substance. Pregnancy, breastfeeding, children, older adults, and people with liver or kidney conditions are commonly excluded from trials; nothing here says whether they were.

What the label states about particular groups

  • On pediatric, the label states: “The efficacy and safety of prednisolone in the pediatric population are based on the well-established course of effect of corticosteroids, which is similar in pediatric and adult populations.”

Where the result stopped carrying

  • STOPAH missed its primary endpoint in the largest alcoholic hepatitis trial ever conducted, and nearly doubled serious infections
  • A five-day course did not shorten hospital stay for preschool children with viral wheeze in 687 analysed patients
  • Doubling the initial course length in childhood nephrotic syndrome changed neither time to relapse nor any secondary outcome
  • Dissociated steroids, designed to keep the transrepression and drop the transactivation, have been pursued for thirty years and none has been approved
  • This is a scope explorer, not a diagnosis engine.
  • It shows who was studied so you can see whether people similar to you were included.

What it would be like to takeRead from sources, not yet reviewed

Why it might seem to do nothing

A real effect and a noticed effect are different things. These are the recorded reasons the two come apart.

It was studied for a different goal

The studies measured something else entirely.

On this record: Some registered studies measured things that match no goal on this page.

It was studied in different people

The people in the studies were not much like the reader.

On this record: Which groups were under-represented in the studies has not been recorded for this substance. Pregnancy, breastfeeding, children, older adults, and people with liver or kidney conditions are commonly excluded from trials; nothing here says whether they were.

The evidence may simply be wrong

Small early studies often do not hold up.

On this record: RNAWiki has not yet published a reviewed conclusion for this use.

Other reasons RNAWiki checked and found nothing for (10)
A different form was studied
The studied form is not the form on the shelf. Nothing in this record points to this reason.
There was nothing to correct
Where a level is already normal, topping it up may change nothing. Nothing in this record points to this reason.
Something else had to happen too
In the studies it was paired with training, a diet or another treatment. Nothing in this record points to this reason.
The change is too small to feel
A real change can still sit below what a person notices. Nothing in this record points to this reason.
Day-to-day swing hides it
Sleep, food, stress and time of day move most numbers more than this would. Nothing in this record points to this reason.
Not enough time yet
The studies ran longer than the person has waited. Nothing in this record points to this reason.
It was not taken as studied
Missed days change the result, and studies count them. Nothing in this record points to this reason.
Something else changed at the same time
Two changes at once cannot be told apart afterwards. Nothing in this record points to this reason.
The product may not be what it says
Contents of a sold product are not always what the label states. Nothing in this record points to this reason.
No recorded reason
RNAWiki has nothing stored that would explain it. Nothing in this record points to this reason.

None of these is a reason to take more. Taking more is not a step this page ever suggests.

What can go wrong

Sorted by where each line came from. A regulator's label and a report somebody sent in are not the same kind of fact.

Worth asking a clinician aboutWritten into the record from the studies named on this page

The label warns of adrenal suppression on withdrawal, increased susceptibility to and masking of infection, reactivation of latent tuberculosis, osteoporosis and fracture, hyperglycaemia, hypertension, fluid retention, cataract and glaucoma, growth suppression in children, peptic ulceration in combination with NSAIDs, and psychiatric disturbance including mania and depression. Live vaccines are contraindicated at immunosuppressive exposure. In a nationwide cohort of 1,548,945 adults, sepsis, venous thromboembolism and fracture rates all rose within 30 days of even a short course, and the rise persisted below a 20 mg prednisone-equivalent daily dose.

Nobody counted how many people took this and were fine, so this cannot be turned into a rate.

Does the exact form matter?

Evidence belongs to the exact thing that was tested. A different salt, a different mixture or a different preparation is a different question.

The form that was studied

Oral solution, oral tablet, orally disintegrating tablet, ophthalmic suspension and emulsion, and injectable sodium phosphate and acetate salts

No source is stored against this line.

What is sold

The sodium phosphate salt is water-soluble and used for injection and for oral solution; the acetate salt is a poorly soluble depot for intra-articular and ophthalmic use. Ophthalmic formulations exist because the eye is one of the few places a glucocorticoid can be delivered locally at high concentration with limited systemic exposure.

What it would be like to takeRead from sources, not yet reviewed

What you could measure

This one is decided with a clinician, so this section holds questions to ask rather than a plan to run.

Self-experiment planning is not offered for a prescription or clinician-supervised medicine. The questions below are for a clinician or pharmacist.

Questions worth asking

  • Which of the trials of Prednisolone studied people like me?
  • What was measured, and for how long?
  • Was the result a laboratory value or a health outcome?
  • What would we watch for, and when would we stop?

Tracking can show whether something changed for you. It cannot show what caused it.

RNAWiki records evidence. It does not say whether this substance is right for you.

Claims that go past the evidence

Things said about this substance that sound reasonable, and the exact step that is missing between the evidence and the claim.

Goes past the evidence

That the standard steroid equivalence table transfers harm as well as potency — it was built from anti-inflammatory bioassay, and adrenal suppression follows half-life instead

Why it sounds right. It follows from something real on this page: a body step, an animal result or a related finding.

The missing step. Nobody measured this in people for this use, or the study that did measure it did not show it.

What would change this

Bell’s palsy: 83.0% recovered against 63.6%, in a placebo-controlled trial
In plain words
This is the cleanest result the drug has. Patients with sudden one-sided facial paralysis were randomly given prednisolone, an antiviral, both or dummy tablets within three days of onset. Four in five on prednisolone had full facial function back at three months. Fewer than two in three did without it. The antiviral did nothing.
What was measured
Complete recovery of facial function on the House-Brackmann scale at 3 and 9 months, against placebo
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
A double-blind, placebo-controlled, factorial trial recruited 551 patients within 72 hours of symptom onset and assessed final outcomes in 496. Recovery of facial function on the House-Brackmann scale at 3 months was 83.0% with prednisolone against 63.6% without it (P<0.001), and at 9 months 94.4% against 81.6% (P<0.001). Acyclovir showed no benefit alone (71.2% against 75.7%, adjusted P=0.50) and added nothing to prednisolone. There were no serious adverse events in any group.

Early rheumatoid arthritis: joint erosion nearly stopped over two years
In plain words
This one measured damage on X-rays rather than how patients felt. Over two years, hands in the prednisolone group barely changed. Hands in the placebo group visibly eroded. It is the trial that established a glucocorticoid can alter the course of the disease and not only its symptoms.
What was measured
Radiographic Larsen index progression and new erosion formation over two years, against placebo
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
A randomised, double-blind trial gave 128 adults with rheumatoid arthritis of less than two years’ duration either oral prednisolone 7.5 mg daily or placebo for two years, alongside their other treatment; radiographic analysis was based on 106 patients with films at baseline and two years. Larsen index scores rose by a mean of 0.72 units on prednisolone against 5.37 units on placebo (P=0.004). Of 147 hands with no erosions at baseline, 22.1% in the prednisolone group and 45.6% in the placebo group had acquired erosions at two years — a difference of 23.5 percentage points (95% CI 5.9 to 40.7, P=0.007). There was no difference between groups in the acute-phase response.

STOPAH: the alcoholic hepatitis indication missed its primary endpoint
In plain words
Prednisolone had been recommended for severe alcoholic hepatitis for decades. The definitive trial randomised more than a thousand patients and found a survival benefit at 28 days that did not reach statistical significance, nothing at all at 90 days or a year, and nearly twice the rate of serious infection.
What was measured
All-cause mortality at 28 days, 90 days and 1 year, against matched placebo
Effect estimate
No reviewed effect estimate exists for this record.
Limits
This entry records a failure.
From the source
STOPAH was a multicentre, double-blind, 2-by-2 factorial trial in 1,103 patients with severe alcoholic hepatitis, with primary-endpoint data from 1,053. Mortality at 28 days was 17% (45 of 269) on placebo-placebo, 14% (38 of 266) on prednisolone-placebo, 19% (50 of 258) on pentoxifylline-placebo and 13% (35 of 260) on both. The odds ratio for 28-day mortality with prednisolone was 0.72 (95% CI 0.52 to 1.01, P=0.06). There were no significant between-group differences at 90 days or at 1 year. Serious infections occurred in 13% of patients treated with prednisolone against 7% of those not treated with it (P=0.002).

Preschool viral wheeze: no better than placebo in 687 children
In plain words
A five-day course of prednisolone was standard practice for small children brought to hospital wheezing with a cold. A trial of 700 of them found it did not shorten their stay in hospital, and did not improve a single secondary measure either.
What was measured
Duration of hospitalisation, against placebo

From the source
A randomised, double-blind, placebo-controlled trial in three English hospitals enrolled 700 children aged 10 to 60 months presenting with mild-to-moderate virus-induced wheeze; 687 were analysed (343 prednisolone, 344 placebo). Duration of hospitalisation was 13.9 hours on placebo against 11.0 hours on prednisolone, a ratio of geometric means of 0.90 (95% CI 0.77 to 1.05) — not significant. There was no significant difference in the Preschool Respiratory Assessment Measure, albuterol use, the 7-day symptom score, or the number of adverse events.

PREDNOS: a longer course in childhood nephrotic syndrome changed nothing
In plain words
Earlier reviews had suggested that giving prednisolone for four months rather than two would keep childhood nephrotic syndrome from coming back. A properly blinded trial gave the extra fourteen weeks as real drug or as matching placebo. Relapse happened at the same rate either way.
What was measured
Time to first relapse over a minimum 24 months, extended against standard course
Effect estimate
No reviewed effect estimate exists for this record.
Limits
This entry records a failure.
From the source
PREDNOS randomised 237 children aged 1 to 14 with a first episode of steroid-sensitive nephrotic syndrome to an extended 16-week prednisolone course (total 3,150 mg/m2) or a standard 8-week course (total 2,240 mg/m2), with matching placebo so tablet counts were identical, across 125 UK hospitals. There was no significant difference in time to first relapse (hazard ratio 0.87, 95% CI 0.65 to 1.17, log-rank P=0.28), nor in frequently relapsing nephrotic syndrome (53% against 50%, P=0.75), steroid-dependent disease (42% against 44%, P=0.77) or need for other immunosuppression (54% against 56%, P=0.81).

Even a short course carries a measurable harm signal
In plain words
A five-day course of steroids is treated as trivial. In a study of more than one and a half million American adults, the thirty days after such a course carried five times the rate of blood poisoning, three times the rate of blood clots and nearly twice the rate of fracture.
What was measured
Incidence rate ratios for sepsis, venous thromboembolism and fracture in the 30 days after a short oral corticosteroid course
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
A retrospective cohort and self-controlled case series across a nationwide United States private-insurance dataset covered 1,548,945 adults aged 18 to 64, of whom 327,452 (21.1%) received at least one outpatient prescription for a course of oral corticosteroid shorter than 30 days over three years. Within 30 days of initiation the incidence rate ratio was 5.30 (95% CI 3.80 to 7.41) for sepsis, 3.33 (2.78 to 3.99) for venous thromboembolism and 1.87 (1.69 to 2.07) for fracture, diminishing over the following 31 to 90 days. The increased risk persisted at prednisone-equivalent doses below 20 mg per day: 4.02 for sepsis, 3.61 for venous thromboembolism, 1.83 for fracture, all P<0.001. The commonest indications were upper respiratory infections, spinal conditions and allergies.

The "steroid-equivalent dose" table is a potency conversion, not an outcome equivalence
In plain words
Every hospital has a chart saying that so many milligrams of one steroid equals so many of another. Those numbers came from measurements of anti-inflammatory potency in the 1950s and 1960s. They were never validated against clinical outcomes, and they do not carry over to bone loss, blood sugar or adrenal suppression, which follow the drug’s half-life rather than its potency.
What was measured
That the standard equivalence table lets one glucocorticoid be swapped for another with the same benefit and the same harm — it is a potency conversion built from anti-inflammatory bioassay, and half-life-driven harms do not follow it
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
Glucocorticoid equivalence tables derive from relative receptor affinity and from bioassays of anti-inflammatory activity, and rank prednisolone at roughly four times cortisol and dexamethasone at roughly 25 to 30 times cortisol. Duration of hypothalamic-pituitary-adrenal axis suppression tracks the biological half-life, which is 12 to 36 hours for prednisolone and 36 to 72 hours for dexamethasone, so equal anti-inflammatory doses do not produce equal adrenal suppression. Mineralocorticoid activity diverges further still: prednisolone retains a fraction of cortisol’s sodium-retaining effect and dexamethasone has essentially none. No randomised trial has shown that equivalent-dose substitution between glucocorticoids produces equivalent clinical outcomes, and the class has no head-to-head programme comparable to the one that exists for, say, the statins.

From "steroids are safe at low dose" to "the threshold is lower than we thought"
In plain words
For decades a small daily dose was treated as effectively harmless. Two large observational analyses moved that line: bone density starts falling above five milligrams a day, and infection and clot risk rise even on short courses under twenty milligrams a day. The class did not become more dangerous; the measurement got better.
What was measured
That low-dose glucocorticoid therapy is free of meaningful harm — an inference from the absence of measurement, which two large analyses have now filled in
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
A meta-analysis of 66 bone-mineral-density papers and 23 fracture papers found strong correlations between cumulative dose and bone loss and between daily dose and fracture risk, with fracture risk rising within 3 to 6 months of starting and falling after stopping, independent of underlying disease, age and sex; it identified more than 5 mg daily of prednisolone or equivalent as the threshold for measurable bone loss. The 2017 nationwide cohort then showed the sepsis, thromboembolism and fracture signal persisted below a 20 mg prednisone-equivalent daily dose in short courses. Both are observational, and confounding by indication is the standing objection: sicker people get more steroid. The self-controlled case series design in the second study, which compares each person with themselves, is the response to that objection rather than a refutation of it.

The older medicine-wide conclusion held in this record

Written for a clinical reader, and about the medicine as a whole rather than about one indication, population and set of trials. RNAWiki does not treat it as a programme conclusion and no reviewer has signed it off in that form. It is here word for word because it is what the record holds.

A synthetic cortisol that binds the glucocorticoid receptor in nearly every cell and switches off the genes that make inflammatory signals — 83.0% of patients recovered facial function by three months in the Bell’s palsy trial against 63.6% without it (p<0.001), and in the largest alcoholic hepatitis trial ever run it missed its primary endpoint with an odds ratio for 28-day mortality of 0.72 (95% CI 0.52 to 1.01, p=0.06) while doubling serious infections.

What do 28066 spontaneous reports say about Prednisolone — and not say?


These are reports people sent to a regulator. They do not show the medicine caused the reaction. Nobody counted how many people took the medicine and reported nothing. The same event can be reported more than once, and many reports are incomplete. News coverage, lawsuits and new warnings change how often people report. A count is not a rate and not a risk.

Prednisolone appears in spontaneous reports to regulators. Across the 10 most-reported reaction terms, 28066 reaction mentions were counted: neutropenia 5374; febrile neutropenia 4674; rheumatoid arthritis 4237; pemphigus 2586. open-targets-adr · CHEMBL131 · 2026-06-24
