Our Zithranol-RR (anthralin cream) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Very few instances of contact allergic reactions to anthralin have been reported. Transient primary irritation and staining of normal or uninvolved skin surrounding the treated lesions, which is frequently seen with other anthralin preparations is less common with Zithranol-RR due to microcrystalline coating of the anthralin particles. If the initial treatment produces excessive soreness or if the lesions spread, reduce frequency of application and, in extreme cases, discontinue use and consult a physician. Some temporary discoloration of hair and fingernails may arise during the period of treatment but should be minimized by careful application. Staining of fabrics may be permanent, so contact should be avoided.
