Selsun (selenium) is used to treat dandruff, seborrhea, and tinea versicolor (a fungus that discolors the skin). It is a topical (for the skin) antifungal medication. This medication is available in generic form. Common side effects include skin irritation, dry skin, oily or dry hair/scalp, or temporary hair loss.
To treat tinea versicolor: Apply the dose of Selsun to affected areas and lather with a small amount of water. Allow product to remain on skin for 10 minutes, then rinse thoroughly. Repeat procedure once a day for 7 days. To treat seborrheic dermatitis and dandruff: Usually two applications each week for two weeks will afford control. After this, may be used at less frequent intervals weekly, every two weeks, or every 3 or 4 weeks in some cases. Avoid using other topical medications at the same time you apply Selsun topical, unless your doctor approves. Other skin medications may affect the absorption or effectiveness of Selsun topical. Tell your doctor all medications you use. If you are using Selsun on the body for tinea versicolor, this medication should be used during pregnancy only when prescribed. It is unknown if this drug passes into breast milk. Though there have been no reports of harm to nursing infants, consult your doctor before breast-feeding.
