Use in Pregnancy
Category C. Animal reproduction studies have not been conducted with Selenos™ Shampoo. It is also not known whether Selenos™ Shampoo can cause fetal harm when applied to the body surfaces of a pregnant woman or can affect reproduction capacity. Under ordinary circumstances, Selenos™ Shampoo should not be used by pregnant women.
It is not known whether or not this drug is secreted in human milk. Because many drugs are secreted in human milk, caution should be exercised when Selenos™ Shampoo is administered to a nursing woman.
In decreasing order of severity: skin irritation; occasional reports of increase in normal hair loss; discoloration of hair (can be avoided or minimized by thorough rinsing of hair after treatment). As with other shampoos, oiliness or dryness of hair and scalp may occur.
There are no documented reports of serious toxicity in humans resulting from acute ingestion of Selenos™ Shampoo. However, acute toxicity studies in animals suggest that ingestion of large amounts could result in potential human toxicity. Evacuation of the stomach contents should be considered in cases of acute oral ingestion.
Dosage and Administration
For seborrheic dermatitis and dandruff: Generally 2 applications each week for 2 weeks will usually control symptoms. After 2 weeks, shampoo may be used less frequently: weekly, every 2 weeks, every 3 to 4 weeks or as directed by a physician. Do not apply more frequently than necessary to maintain control. For tinea versicolor: Apply to affected areas and lather with a small amount of water. Rinse thoroughly after 10 minutes. Repeat procedure once a day for 7 days or as directed by a physician.
