Tars for Psoriasis
Side Effects
Coal tar preparations are generally thought to be safe. There have been some concerns of cancer-causing chemicals in coal tar. But the U.S. Food and Drug Administration (FDA) reports that the chemical concentrations in over-the-counter coal tar are at safe levels. Use coal tar carefully when the skin rash is inflamed or is near the eyes or in skin folds.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
