Psoriasin is a topical, over-the-counter treatment approved by the U.S. Food and Drug Administration (FDA) to treat psoriasis. Psoriasin is also known by its drug name, coal tar. Coal tar is often used as an ingredient in creams, foams, soaps, and shampoos, sometimes in combination with salicylic acid. Doctors may prescribe coal tar at higher strengths than are available over the counter, or recommend that you use coal tar along with a prescription medication. Psoriasin is frequently used to treat psoriasis on the scalp.
Psoriasin is a mild antiseptic and a keratolytic, or medication that promotes peeling. In cases of psoriasis, coal tar is believed to work by relieving itching, reducing inflammation, slowing the growth of cells, and softening scales, making them easier to remove.
How do I take it?
Always check with your doctor before taking a new medication, including over-the-counter medications.
Use products containing coal tar according to directions given by your doctor or found on the medication package. Do not exceed the recommended dosage. Note that products with different concentrations of coal tar are suitable for different parts of the body. For instance, stronger products are appropriate for the scalp, but not the face.
Avoid getting Psoriasin on broken skin, eyes, nose, mouth, anus, or genitals. Wash your hands after applying Psoriasin.
Common side effects of Psoriasin may include staining, irritation, bruising, and thinning of the skin. Blood vessels may become more visible after using Psoriasin.
Psoriasin increases your sensitivity to sunlight and your risk for sunburn for 24 hours after use.
At extremely high concentrations, Psoriasin can increase your risk of developing cancer. However, the FDA has stated that coal tar products are safe for humans at approved concentrations for over-the-counter products.
Seek medical help immediately if you experience symptoms of an allergic reaction such as trouble breathing, severe dizziness, rash, or itching or swelling of the face, tongue, and throat.
