Overview
Prednisolone is a prescription corticosteroid used to reduce inflammation and alter immune responses. The active substance is prednisolone and it is prescribed for many conditions where reducing inflammation or suppressing the immune system is needed.
Routine clinical applications include allergic reactions, rheumatic disorders such as arthritis, respiratory flare ups like acute asthma, some blood and connective tissue diseases including lupus, certain eye inflammations, parts of some cancer treatment plans, endocrine disorders such as adrenal insufficiency, inflammatory bowel disease such as ulcerative colitis, swelling for many causes and a range of dermatological problems.
Capabilities available
In the UK, prednisolone tablets are commonly dispensed in 5 mg, 10 mg, 20 mg and 40 mg strengths. Pharmacists can also provide soluble or liquid forms where needed, and injectable or intravenous preparations exist for hospital use.
This is for whom
Clinicians may prescribe prednisolone for a wide range of problems. Prescribed signs include:
- Severe allergic reactions, including some drug allergies and bad seasonal allergy flare ups.
- Inflammatory joint conditions and other rheumatological disorders.
- Asthma exacerbations and other respiratory inflammatory events.
- Autoimmune blood disorders and connective tissue diseases, for example systemic lupus erythematosus.
- Ocular inflammation such as uveitis or keratitis under specialist supervision.
- Certain malignancies as part of chemotherapy or supportive care.
- Replacement therapy for adrenal insufficiency in some patients.
- Inflammatory bowel disease (IBD), including ulcerative colitis, in acute or maintenance phases.
- Severe dermatological conditions like extensive psoriasis or eczema.
Only take prednisolone when it has been prescribed for you by a qualified prescriber. It may also be used for other off-label indications of if your clinician considers it appropriate.
Strategies to deal with it
Follow your prescription directions precisely. General practical points:
- Adhere to the exact dose and schedule printed on the prescription. If unclear, contact your doctor or pharmacist.
- Tablets are usually swallowed whole; soluble, dispersible or liquid forms should be used only if supplied and instructed.
- Taking prednisolone with food or milk can help limit gastric irritation.
- If you have been on prednisolone for a prolonged period, do not stop suddenly; a tapering plan is often required to avoid adrenal insufficiency.
For vaccine planning, infection concerns or dose adjustments see the Preventive measures and warning signals a part of the document.
The operation method
Prednisolone is a synthetic corticosteroid that works by suppressing inflammatory mediators and dampening immune cell activity. This reduction in inflammation relieves redness, swelling, pain and allergic symptoms.
Skipped dose tips and steps
If you forget about a dose, take the next scheduled dose at the usual time. Do not take a second dose to make up for the dose you missed. If you miss several doses or your therapy involves a gradual dose reduction, contact your prescriber for specific clear guidance.
Disk remote storage solutions reduce on site clutter. care guidance
- Store at around 25 C; short excursions between 15 C and 30 C are acceptable.
- Keep tablets in their original container away from heat, strong light and moisture; avoid storing in a bathroom.
- Do not allow access by children or animals.
Risk warning signals and safety steps
Situations where prednisolone is not recommended
- Known allergy to prednisolone or any excipient in the tablet.
- Systemic fungal infections without therapeutic intervention, some forms of malaria, certain optic nerve inflammations or active herpes simplex infection of the eye.
- Concomitant use with mifepristone.
- When a live attenuated vaccine is planned; live vaccines are generally avoided while on systemic steroids.
If any of the above apply to you, contact your clinician without delay.
Primary safety guidelines to consider beyond this
- Increased infection risk: prednisolone can reduce your immune response. Avoid close contact with people who have contagious infections and seek advice if symptoms of infection develop.
- Vaccinations: discuss any planned immunisations with your healthcare team; live vaccines are often contraindicated while on systemic steroids.
- Always tell healthcare professionals, including dentists and surgeons, that you take prednisolone before procedures or new treatments.
- The disease of impaired insulin action, diabetes: steroid therapy can raise blood sugar. Monitor glucose more frequently and consult your diabetes team before changing therapy.
- Compliance monitoring: blood tests or adrenal function checks may be required during or after treatment.
- The junior generation: steroids can slow growth in some children; regular growth monitoring and logging is recommended.
- During gestation and lactation: discuss risks and benefits with your prescriber, as prednisolone does pass into breast milk.
- Steroid emergency card: in the UK, patients on long courses or high doses are commonly advised to carry a Steroid Emergency Card; ask your prescriber or pharmacist for the information.
Expected incidental effects
Standard and expected effects
Latent effects are more likely at higher doses or early in treatment. Contact your clinician if any effect is persistent or troubling:
- Changes to the skin including acne or thinning.
- The pain in the head, dizziness or a sensation of spinning.
- System flushing or increased sweating.
- Greater appetite and changes in weight.
- Stomach discomfort or nausea.
- Trouble sleeping, nervousness or mood changes.
Major ramifications that need urgent attention
Seek immediate medical help if you experience:
- Signs of a severe allergic reaction such as breathing difficulty, swelling of the face, lips or throat, widespread rash or hives.
- Severe gastrointestinal bleeding or vomiting that looks like coffee grounds.
- Marked mental changes including severe depression, confusion or hallucinations.
- Unusual bruising, persistent fever, sore throat or other infection signs.
- Muscle weakness, severe bone, tendon or joint pain, sudden vision changes.
Other options and similar medications
Treatment choice depends on the condition, severity, and individual patient factors. Do not change or stop medications without professional advice. Options that clinicians may consider include:
- Prednisone: closely related; prednisone is metabolised to prednisolone in the liver and may be preferred or avoided depending on liver function.
- Methylprednisolone: used for similar proof of, available in oral and injectable forms and sometimes chosen for pulse therapy.
- Dexamethasone based therapy: longer acting and more potent per milligram; used in some cancer protocols and when prolonged effect is desired.
- Hydrocortisone: used mainly for adrenal replacement because it is shorter acting and closer to the natural hormone.
- Budesonide: has high first pass metabolism and may be preferred for some inhaled or bowel-targeted treatments with less systemic exposure.
- For asthma maintenance: inhaled corticosteroids such as beclometasone or fluticasone reduce airway inflammation with less systemic impact than oral prednisolone.
- Non-steroidal variant options: NSAIDs for pain and inflammation, antihistamines for allergic symptoms, and disease-modifying drugs for autoimmune diseases may be used instead of or alongside steroids depending on the diagnosis.
As a general note, generic prednisolone is usually among the lower-cost systemic steroids for short courses. See UK price levels when performing typical cost comparisons.
UK price levels

The figures shown are for guidance only. Final prices will depend on pharmacy fees, dispensing charges and whether a consultation is required.
Notes on United Kingdom the legal and regulatory environment matters
- Prescription status: Prednisolone is a Prescription Only Medicine (POM) in the UK. A valid prescription from an authorised prescriber is required to obtain it legally.
- Where to obtain: Only a registered pharmacy may supply prednisolone. For internet or distance sales, confirm the supplier is registered with the General Pharmaceutical Council (GPhC) and provides clear contact details.

- Bringing medicines into the UK: Personal quantities may be permitted but customs rules apply and proof of prescription may be requested. Check current government and MHRA advice before travel.
- Sporting restrictions: Systemic glucocorticoids are prohibited in-competition under WADA without a Therapeutic Use Exemption. Athletes should consult UK Anti-Doping expert counsel.
- Emergency identification: The NHS encourages patients on long term or high dose corticosteroids to carry a Steroid Emergency Card; ask your prescriber or pharmacist how to obtain one.
