Prelone (Prednisolone) – Patient Information

Prelone contains prednisolone, a corticosteroid medicine used to reduce inflammation and calm an overactive immune response. It is commonly prescribed for a range of conditions affecting the skin, lungs, gut, joints and other organs.

This page explains how Prelone works, what it’s used for, typical dosing approaches, important safety information, and practical tips for taking it safely in the United Kingdom.

Basic product information

Always follow the instructions given with your product. Dose and timing vary depending on the condition, age, and how severe symptoms are.

How Prelone works (mechanism of action)

Prednisolone is a synthetic corticosteroid. It helps control inflammation by affecting how cells communicate and respond during immune reactions. In simplified terms, prednisolone:

• Reduces inflammation by limiting the production of inflammatory substances
• Suppresses immune activity, which can be helpful in autoimmune or allergic conditions
• Stabilises immune cell behaviour and reduces swelling and redness
• May affect how the body responds to stress (important for the adrenal system when steroids are used for longer periods)

Prelone is not an antibiotic and does not directly kill bacteria or viruses. If you are fighting an infection, your clinician will balance the benefits of reduced inflammation with the potential for steroids to mask symptoms.

Pharmacokinetics (how your body handles prednisolone)

Pharmacokinetics describes how a medicine is absorbed, distributed, metabolised and eliminated. Prednisolone after oral use is generally absorbed from the gastrointestinal tract and then processed by the liver.

• Absorption: Typically absorbed after swallowing; the exact rate can vary between formulations and individuals.
• Distribution: Prednisolone circulates in the bloodstream and reaches many tissues where it exerts effects.
• Metabolism: Prednisolone is metabolised mainly in the liver into active and inactive metabolites.
• Elimination: Metabolites are excreted primarily via the kidneys and, to a lesser extent, other routes.

The practical takeaway: consistent dosing and attention to liver health and drug interactions can be important for safe use.

Typical uses (indications)

Prelone is used for inflammatory and immune-mediated conditions, including:

• Severe allergic reactions and certain immune conditions (where appropriate)
• Asthma exacerbations and other inflammatory airway disorders (as part of an overall plan)
• Inflammatory bowel disease (e.g., ulcerative colitis or Crohn’s disease flares)
• Autoimmune diseases such as certain connective tissue disorders
• Skin conditions with strong inflammatory/immune involvement
• Rheumatic and joint conditions including some inflammatory arthritis types
• Hematologic and other specialist indications determined by a clinician

Your exact indication determines the dose, duration, and whether a gradual reduction (“taper”) is needed. If you’re unsure why Prelone was chosen for you, check with your healthcare professional.

Timing and how to take Prelone

Many people are advised to take prednisolone once in the morning, usually with breakfast or just after eating. This approach is commonly used because corticosteroids can influence natural hormone rhythms.

• Morning dosing: Often preferred (e.g., shortly after breakfast) to match the body’s natural cortisol rhythm.
• Multiple daily doses: Sometimes used if higher totals are required or for specific conditions. Your schedule may differ from once-daily dosing.
• Consistency: Try to take doses at the same times each day.
• Do not stop suddenly: If you’ve been taking it for more than a short course, stopping abruptly can be unsafe. Dose reduction should be guided by a clinician.

If you miss a dose, take it when you remember unless it is close to the next dose. Do not double the dose to make up for a missed one.

Food interactions and what to eat

Prednisolone can cause stomach irritation in some people. Taking it with food can help reduce this effect. It may also contribute to increased appetite and changes in blood sugar.

• Take with food (especially if you get indigestion or stomach discomfort).
• Stay hydrated and maintain a balanced diet.
• Watch salt intake if you have fluid retention, raised blood pressure, or heart failure history, as steroids can increase sodium and water retention.
• Blood sugar awareness: If you have diabetes or prediabetes, you may need closer monitoring of glucose.

There are no common “must avoid” foods in the same way as with some other medicines, but overall diet choices can strongly influence comfort and side effects.

Alcohol interactions

Alcohol can increase the risk of stomach irritation and may worsen certain side effects such as mood changes, indigestion, and sleep disruption. While a strict prohibition is not always required, it’s generally advisable to:

• Limit alcohol during steroid treatment
• Avoid heavy drinking, particularly if you have a history of ulcers, gastritis, or liver problems
• Seek advice if you take Prednisolone for longer courses or have complex medical conditions

If you notice new heartburn, stomach pain, black stools, or vomiting blood, contact urgent medical services.

Medicine interactions (including OTC and herbal products)

Prednisolone interacts with several medicines and substances. Some interactions can reduce steroid effectiveness, while others can increase side effects. Always provide a full list of your medicines and supplements to your pharmacist or clinician.

Important interaction themes

• Other medicines that affect the stomach: NSAIDs (like ibuprofen) may increase risk of stomach irritation or bleeding when combined with steroids.
• Diabetes medicines: Prednisolone can raise blood glucose; you may need dose adjustments and monitoring.
• Blood thinners: Some anticoagulants can have altered effects with steroids (monitoring may be needed).
• Vaccines: Live vaccines may be unsafe in people taking higher-dose or long-term steroids.
• Antifungals/antibiotics and other liver-metabolised medicines: Some can affect prednisolone levels.
• Drugs that increase infection risk: If you take other immunosuppressants, the combined effect may raise infection risk.

Herbal and supplementary products

• Be cautious with products that affect immunity or liver enzymes.
• Examples of “commonly used” supplements include St John’s wort; this can interact with many medicines.

If you are unsure whether a particular product interacts with prednisolone, ask a pharmacist.

Dosing guidance (general information)

Prednisolone dosing varies widely depending on the condition being treated, severity, and patient factors (age, other illnesses, previous steroid exposure). Your prescriber will provide an exact dose and schedule.

Important: Do not use a dose different from the one given to you.

How dosing may be structured

• Short courses: Often used for flare-ups; may be taken once daily in the morning.
• Longer courses: Commonly require a planned reduction as treatment ends to allow the adrenal glands to recover.
• Higher doses: May be used for severe inflammatory conditions, sometimes with specialist oversight.

Children and older adults

• Children: Doses are typically weight-based and require careful monitoring for growth and side effects.
• Older adults: Higher sensitivity to side effects is possible (e.g., blood sugar, blood pressure, bone health, infection risk).

If you are managing dosing for someone else (such as a child), double-check the concentration on the bottle and measure accurately. If using an oral liquid, use the supplied measuring device rather than kitchen spoons.

Safety profile and side effects

Like all medicines, Prelone can cause side effects. Many are dose- and duration-dependent. Short-term use is often tolerated, but even short courses can produce noticeable effects in some people.

Common side effects

• Increased appetite and possible weight gain
• Indigestion or stomach discomfort
• Difficulty sleeping (especially if taken later in the day)
• Mood changes such as irritability or anxiety
• Fluid retention (e.g., swelling in ankles)
• Raised blood sugar (particularly relevant for people with diabetes)
• Headache

Less common but serious effects (seek medical advice promptly)

• Signs of infection (fever, chills, severe sore throat, shortness of breath). Steroids can mask symptoms.
• Severe stomach problems (black stools, blood in vomit, severe persistent abdominal pain).
• Allergic reaction (swelling of face/lips, rash, breathing difficulty).
• New vision symptoms (e.g., blurry vision) or eye pain.
• Severe mood/behaviour changes, confusion, or unusual agitation.

Risk with longer use

With extended treatment or repeated steroid courses, the risk of complications increases, including:

• Bone thinning (osteoporosis) and fractures
• Muscle weakness
• Skin thinning and easy bruising
• Cataracts and glaucoma
• Adrenal suppression (the body’s own cortisol production can decrease)
• Higher blood pressure and lipid changes

If you are on steroids for more than a short period, your clinician may recommend preventative measures such as bone protection and monitoring.

When you should seek urgent help

Contact urgent medical services if you develop:

• Severe allergic symptoms (trouble breathing, swelling of face/throat)
• Signs of a serious infection (high fever, severe shortness of breath, confusion)
• Black/tarry stools, vomiting blood, or severe abdominal pain
• Severe worsening of mental health symptoms or inability to sleep for multiple nights

Practical use tips (getting the best results safely)

• Take it at the right time: If prescribed once daily, aim for morning dosing.
• Take with food: Helps reduce indigestion.
• Measure liquids accurately: Use a proper dosing syringe or cup.
• Keep track of changes: Note improvements in symptoms and any side effects.
• Don’t share your medicine: Steroid dosing is highly individual.
• Carry a steroid alert (if advised): especially for long courses, because steroid therapy can affect how the body responds to stress.
• Attend follow-up: Monitoring may include blood pressure, weight, blood sugar, eyes, and bone health depending on duration.
• Plan when stopping: If you’ve used it for more than a short course, ask for a clear stopping/taper schedule.

Alternative options

Depending on the condition you’re treating, alternatives may include other corticosteroids, inhaled therapies (for asthma), or non-steroid anti-inflammatory or immunomodulating medicines. Your clinician will tailor options to your diagnosis, severity, and risk profile.

Common alternative approaches may include

• Other corticosteroids (e.g., different steroid types or routes such as inhaled or topical forms)
• Non-steroidal anti-inflammatory medicines for selected conditions
• Biologic or disease-modifying treatments for chronic inflammatory diseases (specialist-led)
• Supportive care and trigger avoidance alongside medication

If you are considering switching away from prednisolone, do not stop abruptly—ask your healthcare professional about a safe transition.
