Logidruf-S Solution is used to treat skin conditions such as psoriasis, dandruff, and to control seborrheic dermatitis (characterised by scaly patches and red skin on the scalp). It contains Salicylic acid and Coal Tar, which break down the clumps of keratin, remove dead skin cells, and soften the skin. It may cause common side effects, such as warmth, a burning sensation, skin irritation, itching, and redness at the application site. Before using this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions.
