Prednisolone Medications

Prednisolone Info

What is Prednisolone?

Prednisolone is a synthetic glucocorticoid used to reduce inflammation and modify the body's immune response. It belongs to the corticosteroid class of medicines, which mimic the natural hormone cortisol. In Hong Kong, prednisolone is available in several forms, including tablets, oral suspensions, eye drops, topical creams and injectable solutions, and it is marketed under brand names such as Prelone as well as the generic name Prednisolone.

Medications that Contain Prednisolone

A variety of products in Hong Kong contain prednisolone as the active ingredient. The most commonly encountered ones are:

• Prelone - available as oral tablets (5 mg, 10 mg) and as an oral suspension for those who prefer a liquid form.
• Prednisolone - sold as generic tablets, a syrup for children, ophthalmic drops for eye inflammation, and a cream for skin conditions.

Both brand and generic versions may be supplied in single-strength tablets or combined with other agents, such as a bronchodilator for asthma inhalers. The dosage strength and formulation differ between products, so each package carries its own instructions.

What Does Prednisolone Treat?

Prednisolone is prescribed for a range of inflammatory and immune-related conditions. Typical uses include:

• Allergic reactions - such as severe skin rash or allergic asthma attacks.
• Autoimmune diseases - including rheumatoid arthritis, systemic lupus erythematosus and inflammatory bowel disease.
• Dermatologic inflammation - conditions like eczema, psoriasis or contact dermatitis that require topical treatment.
• Respiratory disorders - exacerbations of asthma or chronic obstructive pulmonary disease (COPD).
• Eye inflammation - uveitis, keratitis and other ocular conditions managed with prednisolone eye drops.

These uses are recognised by the Hong Kong Department of Health and align with the drug’s anti-inflammatory properties. While some clinicians may employ prednisolone off-label for other inflammatory problems, the primary approved indications remain those listed above.

How Prednisolone Works

Prednisolone mimics the action of the body’s natural cortisol, helping to calm the immune system and decrease swelling. By limiting the release of substances that trigger inflammation, it eases redness, pain and tissue swelling. The effect can be noticeable within a few hours for acute symptoms, although longer courses may be needed for chronic conditions.

Safety Information

Common Side Effects

Most people experience only mild, temporary effects, such as:

• Increased appetite or slight weight gain.
• Mild insomnia or changes in mood.
• Stomach discomfort or heartburn.
• Slight thinning of the skin or easy bruising.

These symptoms usually resolve when treatment ends or the dose is reduced.

Serious Reactions

Rare but important reactions can occur. Seek urgent medical help if you notice:

• Severe breathing difficulty or swelling of the face and throat.
• Rapid heartbeat, high fever or signs of infection that worsen quickly.
• Sudden vision changes, severe headache or signs of an allergic reaction (hives, rash, itching).

Who Should Be Cautious

Prednisolone may not be suitable for everyone. Special care is advisable for individuals with:

• Known hypersensitivity to corticosteroids.
• Uncontrolled diabetes, hypertension or osteoporosis.
• Active infections, including tuberculosis or fungal infections.
• Pregnancy or breastfeeding, unless a clinician determines the benefit outweighs the risk.

Interaction Awareness

Prednisolone can interact with several other substances. General points to keep in mind:

• Non-steroidal anti-inflammatory drugs (NSAIDs) - may increase the risk of stomach irritation or ulcers.
• Blood thinners (e.g., warfarin) - corticosteroids can affect clotting times.
• Vaccines - live vaccines may be less effective while taking systemic steroids.
• Alcohol - can worsen stomach upset and increase blood-sugar fluctuations.

For a complete list of possible interactions, refer to the product-specific information leaflets.

What to Know Before Using

Store prednisolone-containing products at room temperature, away from moisture and direct sunlight. Keep them out of reach of children. Treatment length varies: short courses are typical for acute flare-ups, whereas chronic conditions may require longer therapy under close supervision. Because formulations differ-tablet versus eye drop versus cream-always follow the directions printed on the specific medication you have.

Key Terms

Glucocorticoid: A type of steroid hormone that reduces inflammation and modifies immune activity.

Inflammation: The body’s natural response to injury or irritation, often causing redness, swelling, heat and pain.

Immunosuppression: Lowering the activity of the immune system, which can help control autoimmune diseases but may increase infection risk.

Topical: Applied directly to the skin or eyes, as opposed to systemic (taken by mouth or injection).

Systemic: A medication that works throughout the whole body after being absorbed into the bloodstream.
