High level briefing
Prednisolone is a prescription corticosteroid used to control inflammation and suppress overactive immune responses. It is prescribed for many acute and chronic conditions where reducing inflammation or modulating immunity is required.
Standard clinical uses span allergic reactions, inflammatory joint disease, exacerbations of respiratory conditions such as asthma, selected autoimmune and haematological disorders, eye inflammation, part of some oncology regimens, adrenal replacement in specific situations, inflammatory bowel disease and a variety of skin disorders.
Available strengths
In the UK, oral prednisolone is typically supplied in tablet strengths such as 5 mg, 10 mg, 20 mg and 40 mg. For patients who cannot swallow tablets, liquid or soluble preparations may be available. Hospitals also use injectable forms for intravenous or intramuscular administration.
Whom is this for
Prescribers may choose prednisolone for a variety of disorders. Frequent manifestations include:
- Severe allergic reactions and significant seasonal allergy flares.
- Rheumatic illnesses and inflammatory joint conditions.
- Acute asthma attacks and other respiratory inflammatory events.
- Autoimmune blood disorders and connective tissue diseases such as systemic lupus.
- Ocular inflammations like uveitis under ophthalmology supervision.
- Supportive or direct use within some cancer treatment plans.
- Adrenal insufficiency when replacement is appropriate.
- Moderate to severe inflammatory bowel disease including ulcerative colitis.
- Extensive dermatological problems such as severe eczema or psoriasis.
Only take prednisolone if it has been prescribed for you. For off-label uses your clinician should explain the reasons and expected benefits.
How to process it
Follow the dosing schedule written on your prescription. Practical advice includes:
- Stick to the exact when and how much to take the dose advised by your prescriber or pharmacist. If the directions are unclear, contact them for clarification.
- Swallow tablets whole unless the product is labelled as dispersible or soluble and you were instructed to dissolve it.
- Taking prednisolone with food or milk often reduces stomach irritation.
- If you have been on treatment for many weeks or months, do not stop abruptly; gradual tapering may be necessary to avoid adrenal insufficiency.
For questions about vaccines, infection risk or dose reductions, consult the warning signs and precautionary actions section or speak to your prescriber.
How it operates step by step
Prednisolone is a synthetic steroid hormone that decreases production of inflammatory mediators and reduces activity of certain immune cells. By lowering inflammation, symptoms such as swelling, pain and redness improve.
Management tips after a failure to take a dose
If you miss a dose, take the next dose at the usual time. Do not exceed one dose at a time to catch up. If you miss several doses or are on a reducing regimen, contact your prescriber for tailored advice.
Advice on access to storage space determines how quickly items can be retrieved.
- Keep at around 25 C; brief excursions between 15 C and 30 C are acceptable.
- Store in the original container, away from direct heat, sunlight and dampness; avoid bathrooms.
- Store in a place unreachable by children and pets. and dispose of unused medicine safely.
Warning notes and measures for safety
When prednisolone should be avoided
- Known hypersensitivity to prednisolone or any ingredient in the product.
- Untreated systemic fungal illnesses or some parasitic infections.
- Certain eye infections such as active herpes simplex affecting the eye.
- The simultaneous use of mifepristone.
- Planned administration of live vaccines while on systemic steroids.
If any of these apply to you, contact your healthcare professional before taking prednisolone.
Other important safety considerations
- Infection risk: steroid treatment can weaken immune defenses. Avoid close contact with contagious illnesses and report any signs of infection promptly.
- Vaccinations: discuss planned immunisations with your clinician since live vaccines are often contraindicated while on systemic steroids.
- Inform all healthcare providers, including dentists and surgeons, that you are taking prednisolone prior to procedures.
- Diabetes, the high blood sugar disorder: steroids can raise blood glucose. If you have diabetes, monitor your levels more closely and consult your diabetes team about dose adjustments.
- Security monitoring: blood tests or reexamines of adrenal function may be needed during or after prolonged therapy.
- Young ones: long-term steroid use can affect growth; regular growth checks are recommended.
- Gestation and nursing: discuss risks and benefits, as prednisolone is partly transferred into breast milk.
- Steroid emergency information: in the UK, patients on long-term or high-dose courses are commonly advised to carry a Steroid Emergency Card. Ask your prescriber or pharmacist for details, see the following.
Possible effects on your body
Expected or typical effects
Long term effects are more likely at higher doses or early in therapy. Contact your clinician if any effect is severe or persistent:
- Skin changes, such as acne or thinning of the skin.
- Cephalalgic pain, dizziness or balance disturbances.
- Pipe flushing or increased sweating.
- Boosted appetite with weight change.
- Gastrointestinal upset including nausea or indigestion.
- Sleep problems, mood swings or anxiety.
Significant repercussions that need urgent attention
Seek immediate medical help if you notice any of the following:
- Signs of a severe allergic reaction: difficulty breathing, swelling of the face, lips or throat, widespread rash or hives.
- Severe gastrointestinal bleeding or vomiting that resembles coffee grounds.
- Major mental changes such as severe depression, confusion or hallucinations.
- Unusual bruising, persistent fever, sore throat, or other signs of serious infection.
- Marked muscle weakness, sudden severe bone or joint pain, or acute changes in vision.
Alternate medicines and similar drugs
Selection of an an alternate path depends on diagnosis, severity and patient factors. Do not switch or stop medicines without professional directional support. Some different choices clinicians may consider include:
- Methylprednisolone - used in similar situations; available orally and by injection and sometimes chosen for pulse therapy.
- Prednisone - converted to prednisolone in the liver; choice may depend on liver function and local prescribing practice.
- Dexamethasone pharmaceutical agent - longer acting and more potent milligram for milligram; used where a prolonged effect is desired.
- Hydrocortisone - preferred for adrenal replacement because it more closely resembles the natural hormone.
- Budesonide - has high first-pass metabolism and can provide localised effect in the bowel or airway with less systemic exposure.
- For chronic respiratory care: inhaled steroids such as beclometasone or fluticasone reduce airway inflammation with much lower systemic impact than oral prednisolone.
- Non-steroidal options: NSAIDs, antihistamines or disease-modifying antirheumatic drugs may be used instead of or alongside steroids depending on the condition.
Generic prednisolone is generally among the lower-cost systemic corticosteroids for short-term courses. For cost evaluation and side by side price comparison, access the comparison page uK price data.
