Indications

This medication is a combination antibiotic and steroid used on the skin to treat an infection and relieve associated itching and swelling.

Composition

Each gm cream or ointment contains:
  • Triamcinolone 1 mg
  • Neomycin 2.5 mg
  • Nystatin 10000 unit
  • Gramicidin 0.25 mg

Pharmacology

Triamcinolone is a fluorinated corticosteroid with anti-inflammatory, antipruritic and anti-allergic actions.

Nystatin, a polyene antifungal antibiotic, binds to ergosterol and interferes with the permeability of cell membrane of susceptible fungi e.g Candida spp.

Neomycin is an aminoglycoside, often used topically in the infections against susceptible staphylococci and other organisms.

Gramicidin, an antibacterial substance extracted from tyrothricin, is active against many Grampositive bacteria. Used together, this combination provides a wide coverage against gram-positive, gram-negative bacteria and yeast which are responsible for most of the skin infections.

Dosage & Administration

This medication is for use on the skin only. Wash your hands before using. Avoid getting this product in your eyes or inside the mouth. If this occurs, wipe off the medication and rinse thoroughly with water. Do not use inside the nose unless directed by your doctor.

Clean and dry the affected area as directed. Apply a small amount of medication in a thin layer on the skin and rub in gently, usually 2 to 3 times daily or as directed by your doctor. Wash your hands after use.

Do not bandage, wrap, or cover the treated area unless you are instructed to do so by your doctor. If this medication is applied to the groin area, do not use tight-fitting plastic pants/diapers/garments for incontinence (loss of control of your bladder or bowels). Doing so may increase the absorption of this product through the skin and increase the risk for side effects.

Do not use large amounts of this medication, apply it more often, or use it for a longer time than directed. Your condition may not improve faster, and the risk for side effects may be increased.

Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same times each day.

Tell your doctor if your condition does not improve or if it worsens after 1 week.
