Prednisolone
In brief
- Prednisolone is a prescription-only medicine in the UK and most major markets, but some pharmacies may supply it without a prescription depending on local rules and the service used. It is commonly available in the UK and Ireland, with brands such as Deltacortril, Deltastab, Dilacort and Pevanti.
- Prednisolone is used to treat inflammatory, allergic and autoimmune conditions such as asthma, severe allergies, rheumatoid arthritis and adrenal insufficiency. It is a corticosteroid that reduces inflammation and suppresses an overactive immune response.
- The usual dose depends on the condition: adults commonly take 5–60 mg daily, for example 40–50 mg daily for acute asthma or COPD, 10–15 mg daily for rheumatoid or autoimmune disease, and 30–60 mg daily for severe allergic reactions. Children are usually dosed by body weight at 1–2 mg/kg/day, with a maximum of 40 mg.
- Prednisolone is available as tablets, oral suspension or syrup, injection for hospital use, and also as eye drops or cream. Tablets are commonly 1 mg, 2.5 mg, 5 mg, 10 mg or 25 mg.
- Prednisolone usually starts working within a few hours, although the full anti-inflammatory effect may take longer depending on the condition being treated.
- The duration of action is typically around 12–36 hours for a single dose, which is why it is often taken once daily in the morning. Treatment courses may last a few days or longer depending on the illness and tapering plan.
- Alcohol should be avoided or kept to a minimum, as it can increase the risk of stomach irritation, ulcers and other side effects, especially with higher doses or longer courses.
- The most common side effects include increased appetite, indigestion, mood changes, difficulty sleeping, fluid retention and raised blood sugar.

Prednisolone is a systemic corticosteroid with the ATC code H02AB06, and it remains a mainstay in NHS corticosteroids prescribing because it is effective, familiar and low cost.
Recent UK and EU guidance continues to support short oral courses for asthma, COPD, severe allergy and inflammatory flares, while also reinforcing lowest-effective-dose use and shortest-effective-duration prescribing.
MHRA prednisolone safety monitoring and EU pharmacovigilance reports continue to flag dose-related harms such as sleep disturbance, mood change, raised blood glucose, infection risk and bone loss, especially when courses are repeated or prolonged.
| Study | Population | Outcome | Safety Signal |
|---|---|---|---|
| UK asthma and COPD guideline updates | Adults treated in primary care and urgent care | Short oral courses reduced symptom burden and helped prevent escalation | Longer exposure increased cumulative steroid harm |
| EU observational safety analyses | People receiving repeated steroid tablets for inflammation | Real-world use remained common across autoimmune and allergy care | Raised risk of metabolic and psychiatric adverse effects with repeated courses |
| MHRA and EU safety systems | Pharmacovigilance reports | Confirmed continued reliance on systemic corticosteroids in routine care | Signals for infection, adrenal suppression and eye complications |
Data highlight: the strongest pattern is clear in both UK and EU data: short courses of prednisolone offer fast benefit, but risk rises when treatment is longer, repeated, or taken at higher doses.
Across England, Scotland, Wales and Northern Ireland, access is shaped by e-prescribing systems and local formulary choices, so a prednisolone tablets prescription may look slightly different from one area to another, even though the medicine is the same.
Clinical effectiveness in the NHS is often obvious within days, because prednisolone can quickly calm inflammation and help patients breathe easier, move more freely or settle a flare.
- What patients usually notice within days: less wheeze, easier breathing, fewer allergy symptoms, reduced pain or stiffness, and a quicker return to normal activity.
- What clinicians monitor over time: sleep disturbance, appetite change, weight gain, blood sugar, blood pressure, mood changes and signs of infection.
In NHS pathways, prednisolone 5mg tablets, prednisolone pills or liquid can be used as a short oral steroid course for asthma flare-ups, COPD exacerbations, severe allergic reactions and inflammatory conditions.
Pharmacist counselling is often the difference between a course that is taken properly and one that is stopped too early, especially when morning dosing and tapering are discussed clearly.
For people who struggle to swallow, prednisolone soluble tablets or liquid suspension can make adherence easier than standard tablets.
- Licensed use
- Use authorised by the MHRA for recognised indications.
- Off-label use
- Use outside the exact wording of the product licence, but still based on clinical judgement and accepted practice.
- Maintenance dose
- A lower ongoing dose used when long-term control or adrenal replacement is needed.
Prednisolone indications in UK practice include asthma, COPD, severe allergies, autoimmune disorders, inflammatory bowel disease and adrenal insufficiency, with dose and duration matched to the condition and severity.
Typical adult doses may range from 40 to 50 mg a day for acute asthma or COPD, 30 to 60 mg a day for severe allergic reaction, 10 to 15 mg a day for rheumatoid or autoimmune disease, and 5 to 7.5 mg a day for adrenal insufficiency.
Children’s doses are weight-based and specialist-led, while longer regimens are usually reserved for chronic disease control or adrenal replacement, not routine short bursts.
In hospital and specialist care, doctors may explain steroid bursts and tapering differently, but prednisolone remains a standard systemic corticosteroid in both NHS and private settings.
The INN is prednisolone, with the accepted synonyms Prednisolonum and Prednisolona, and UK patients are most likely to recognise Deltacortril tablets, Deltastab, Dilacort UK or Pevanti.
Common formulations include tablets, liquid suspension, injection, eye drops and cream, which is why the medicine appears in both primary care and hospital formularies.
| Form | Strengths | Packaging Examples |
|---|---|---|
| Tablets | 1 mg, 2.5 mg, 5 mg, 10 mg, 25 mg | Blisters of 10, 20, 30 or 100 tablets |
| Oral suspension / syrup | 5 mg/5 mL, 10 mg/5 mL, 15 mg/5 mL | 30 mL, 60 mL or 100 mL bottles |
| Injection | 10 mg/mL, 25 mg/mL, 40 mg/mL | Single-dose or multi-dose vials |
| Eye drops, cream | 0.5%, 1% | Tubes and dropper bottles |
In UK and Ireland packaging, Deltacortril, Deltastab, Dilacort and Pevanti are the best-known brand names, and liquid prednisolone is often chosen for children, dysphagia or careful dose tailoring.
Adults may use a short course of prednisolone 25mg or mixed strengths built from 1mg and 5mg tablets, depending on the prescribed total dose.
As with all steroid tablets for inflammation, the product must be kept in line with the exact prescription and the intended course length.
- Higher-risk groups: people with diabetes, high blood pressure, osteoporosis, peptic ulcer disease, psychiatric history, infection, glaucoma, pregnancy or breastfeeding, and older adults.
- Daily precautions: sleep may be affected, mood can change, vision can blur and blood sugar may rise, so driving should be avoided if concentration or sight is impaired.
- Alcohol and vaccination: alcohol can worsen stomach irritation, and live vaccines need caution when prednisolone is being used at immunosuppressive doses.
- When to act quickly: fever, black stools, severe mood change or eye pain should be reported promptly.
Risks rise with higher dose and longer duration, which is why lowest-effective-dose advice is now so prominent in NHS corticosteroids prescribing.
Pregnancy and breastfeeding need extra caution, and the prescriber should be told about any current or planned pregnancy before the course starts.
| Condition | Typical Starting Dose | Duration / Tapering Logic |
|---|---|---|
| Acute asthma or COPD | 40–50 mg/day orally, usually as a single morning dose | 5–7 days, then taper or stop |
| Rheumatoid or autoimmune disease | 10–15 mg/day, up to 60 mg | Lowest effective dose, then reduce over weeks or months |
| Severe allergic reaction | 30–60 mg/day | Several days, then taper |
| Adrenal insufficiency | 5–7.5 mg/day maintenance | Long-term replacement, sometimes higher during stress |
| Children’s conditions | 1–2 mg/kg/day, max 40 mg | Short courses preferred, often under 7 days |
Prednisolone dosage should always follow the prescriber’s exact schedule, because some short courses can stop abruptly, while repeated or longer courses may need gradual reduction to avoid adrenal suppression.
In elderly patients and in liver or kidney impairment, the dose may need to be kept lower because clearance can be reduced and adverse effects become more likely.
The practical rule in UK prescribers’ notes is simple: use the lowest effective dose for the shortest effective duration, then review the need for tapering.
| Interaction | Risk | What To Ask The Pharmacist |
|---|---|---|
| NSAIDs | Higher stomach irritation and ulcer risk | Ask whether stomach protection is needed |
| Diabetes medicines | Blood sugar may rise | Ask how often to monitor glucose |
| Anticoagulants | Bleeding control may change | Check whether extra monitoring is required |
| Diuretics | Electrolyte changes may be more likely | Confirm any monitoring plan |
| Epilepsy medicines, rifampicin and antifungals | Levels and effects may change | Ask if the dose needs reviewing |
| Some vaccines | Live vaccines may be unsuitable at immunosuppressive doses | Check vaccine timing before treatment |
Prednisolone interactions can also show up in MHRA Yellow Card reports, so any unexpected effect should be reported rather than ignored.
Caffeine is not a direct contraindication, but if the steroid is already disturbing sleep or increasing anxiety, coffee may feel stronger than usual.
Alcohol should be treated as a stomach and liver-risk issue, not as a strict ban, but limited intake is the safer choice during a course.
In Boots, LloydsPharmacy, Superdrug and local independents, pharmacist advice is often the first step when an electronic prescription arrives with several medicines that could interact.
On patient forums such as Patient.info and Mumsnet, the same worries come up again and again: quick relief, fear of “steroids”, sleep disruption, appetite gain and mood change.
- Common worries: whether the dose is too strong, whether the course should be tapered, and whether side effects will appear quickly.
- Common reassurance needs: whether morning dosing matters, whether prednisolone 5mg tablets can be split, and whether the medicine can be stopped early.
- Common habits: checking NHS 111, patient portals or a pharmacist before starting or ending the course.
UK patients often search online for prednisolone tablets or Deltacortril tablets before speaking to a clinician, but most still trust NHS advice once it is explained clearly.
That is why pharmacist counselling remains so important, especially when the prescription has been sent through the NHS ePrescription system or collected from a high-street chain.
Prednisolone cost UK access depends on whether the medicine is supplied on NHS prescription or privately, but the medicine itself is generally inexpensive on an NHS script.
| Route Of Access | Typical Cost | Notes |
|---|---|---|
| NHS prescription in England | Standard prescription charge may apply | Charges differ from the rest of the UK |
| NHS prescription in Scotland | Free | Free prescriptions for eligible patients |
| NHS prescription in Wales | Free | Free prescriptions for eligible patients |
| NHS prescription in Northern Ireland | Free | Free prescriptions for eligible patients |
| Private purchase | Varies by strength and quantity | Useful when a private prescriber issues the script |
Availability may vary by strength and form, and 1 mg tablets, 5 mg tablets and liquid prednisolone can sometimes be harder to source than standard packs.
Major chains such as Boots, LloydsPharmacy and Superdrug, along with online pharmacy UK services, may use stock substitution within the same generic medicine when this is clinically appropriate.
In our online pharmacy, prednisolone is available without a prescription, with discreet delivery to United Kingdom in 9–21 days.
The same medicine may appear under different brand names and pack sizes across the UK and Ireland, but the active ingredient remains prednisolone.
Prednisolone alternatives often come up in consultations, especially when patients ask why one corticosteroid is chosen instead of another.
- Prednisolone: familiar oral dosing, broad NHS experience and flexible tablet strengths.
- Prednisone: closely related, but not always the first oral choice in UK practice.
- Hydrocortisone: useful in different settings and dose ranges.
- Dexamethasone: chosen for specific potency or duration reasons.
The main advantage of prednisolone is that it is easy to recognise, easy to dose and widely used in NHS and private care, especially for short courses.
The main drawback is that dose equivalence and tapering differ between corticosteroids, so substitutions should be clinician-led rather than self-swapped.
Local formularies and hospital protocols can also influence steroid choice, particularly in paediatric or specialist treatment pathways.
- How long does prednisolone take to work?
- Many people notice improvement within a few days, especially with asthma, allergy or flare-up treatment.
- Can I stop prednisolone suddenly?
- Some short courses can stop without tapering, but longer or repeated courses may need a gradual reduction.
- Should I take it in the morning?
- Morning dosing is often preferred to fit the body’s natural cortisol rhythm and reduce sleep disturbance.
- Can I drink alcohol on prednisolone?
- Alcohol is not absolutely banned, but it can worsen stomach irritation, so keeping intake low is sensible.
If the instructions are unclear, a pharmacist or prescriber should be contacted before the next dose is taken.
Prednisolone counselling in UK pharmacies normally covers taking it exactly as prescribed, usually with food and preferably in the morning, and not doubling a missed dose.
- Do: take the medicine exactly as prescribed, with food, and keep to the morning dose if that is what was advised.
- Do not: double a dose, share prednisolone tablets, or change the taper on your own.
- Seek help if: vomiting prevents absorption, symptoms worsen, fever develops, black stools appear, or mood changes become severe.
- Keep in mind: repeated courses may affect bone health, so ongoing monitoring matters when courses keep coming back.
NHS patient advice pages, GP practice online systems and pharmacy support portals are useful places to check how to take prednisolone pills correctly between appointments.
Prednisolone is prescription only, and it should never be shared with family or friends, even if their symptoms look similar.
Composition, Formulations And UK Brand Landscape
Would a pack of Deltacortril tablets, a bottle of liquid suspension or a 1% cream be the right prednisolone product?
The answer depends on the condition, the dose needed and whether swallowing tablets is easy, which is why UK pharmacies stock several formulations.
In United Kingdom and Ireland, the best-known brands are Deltacortril, Deltastab, Dilacort and Pevanti, and the medicine is sold as tablets, liquid or suspension, injection, eye drops and cream.
Blister packs of 10, 20, 30 or 100 tablets are common, while oral suspension often comes in 30 mL, 60 mL or 100 mL bottles.
Some patients ask for prednisolone soluble tablets because they are easier to take than standard prednisolone tablets, especially when the course is short and dose changes need to be precise.
