Biotar Ointment 25 gm is a dermatological medication used to treat and control skin conditions like psoriasis of the scalp, dandruff, and seborrheic dermatitis (scaly patches and red skin on the scalp). Psoriasis is a skin disorder in which skin cells multiply up to 10 times faster than usual, leading to skin build-up into bumpy (uneven) red patches covered with white scales. These commonly appear on the scalp, elbows, knees, and lower back. 

Biotar Ointment 25 gm is composed of: Salicylic acid (peeling agent), Coal tar, and Sulphur. Salicylic acid is a keratolytic medicine (softens, separates, and causes desquamation (peeling) of the cornified epithelium or horny layer of skin). It increases the amount of moisture in the skin and dissolves the substance that causes the skin cells to stick together. It breaks down the clumps of keratin, removes dead skin cells, and softens the skin. Coal tar is a keratoplastic (thickens the keratin layers) agent. It works by removing dead cells from the skin’s top layer and slowing down skin cells' growth. This effect decreases scaling and dryness, thus relieving itchiness from various skin conditions. Sulphur is an antiseptic agent and relieves itching. It also has an antifungal action and promotes the shedding of the skin.

Biotar Ointment 25 gm is for topical (for skin use) only. Biotar Ointment 25 gm has common side effects like warmth or a burning sensation, skin irritation, hair loss, acne-like eruptions, peeling of the skin, itching, and redness at the application site.
