Mezolax is a widely prescribed topical medication used to manage inflammatory skin conditions. It's a type of corticosteroid that reduces the body's inflammatory response in the skin. Mezolax is available as a cream, lotion, or ointment.
How Does Mezolax Work?
The main active ingredient in Mezolax is Mometasone Furoate (0.1% w/w). Mometasone is a potent corticosteroid that reduces inflammation by inhibiting the release of inflammatory chemicals in the skin. In response to irritants, the body releases substances that cause redness, swelling, and itching. Mometasone helps suppress this response.
Some versions, like Mezolax S Ointment, also contain Salicylic Acid. Salicylic acid is a keratolytic agent that helps soften and break down keratin, aiding in the removal of dead skin cells and exfoliating scaly patches, such as those found in psoriasis. This also improves the absorption of mometasone.
Conditions Treated with Mezolax
Mezolax is prescribed for various skin conditions that respond to topical corticosteroids.
Eczema (Atopic Dermatitis) Mezolax helps manage eczema flare-ups by reducing inflammation and itching. Using Mezolax alongside moisturizers can help soothe the skin.
Psoriasis Psoriasis causes thick, scaly patches on the skin. Mezolax is used to control inflammation and scaling. Mezolax S Ointment, with salicylic acid, is especially helpful for thicker plaques by exfoliating scales and improving mometasone penetration. Lifestyle changes may also support skin health.
Other Dermatoses Mezolax is also effective for contact and seborrheic dermatitis, reducing redness, swelling, and itching.
Proper Usage and Administration
Use Mezolax exactly as prescribed by a healthcare provider.
- Wash and dry the affected area.
- Apply a thin layer of cream or ointment to the affected skin.
- Massage gently until absorbed.
- Wash hands afterward, unless treating hands.
- Apply typically once or twice daily. Do not overuse or use longer than prescribed.
Important Precautions:
- For external use only. Avoid eyes, mouth, and nose.
- Do not apply to face, groin, or underarms unless directed by a doctor.
- Avoid covering the treated area with bandages unless advised by a doctor.
- Do not use on broken, infected, or ulcerated skin.
Potential Side Effects and Safety Warnings
Mezolax can cause side effects.
Common Local Side Effects These may include burning, stinging, itching, dryness, or redness at the application site.
Less Common and Serious Side Effects Prolonged or excessive use can lead to skin thinning, stretch marks, folliculitis, acne, or systemic absorption of the steroid, which can cause more serious issues like Cushing's syndrome or adrenal gland suppression. Children are at higher risk of systemic absorption. Vision problems can also occur rarely.
Seek medical attention for severe irritation, signs of infection, or symptoms of systemic side effects.
