Coal Tar Extract is primarily used to treat plaque psoriasis, atopic dermatitis (eczema), seborrheic dermatitis, and other conditions involving dry, scaly, or itchy skin. It may also be found in dandruff shampoos for scalp conditions.
Coal tar extract contains multiple active compounds that work by slowing rapid skin cell proliferation (keratoplastic effect), reducing inflammation, softening keratin (keratolytic effect), and decreasing itching. It is believed to affect DNA synthesis in skin cells and have mild antiseptic properties.
Coal tar preparations may cause skin irritation, staining of clothing or bedding, and increased sun sensitivity. Avoid applying to broken, inflamed, or infected skin and keep away from eyes. Use with caution during pregnancy and breastfeeding. May interact with other topical medications; consult a healthcare provider before combining treatments.
