How are oral finasteride and compounded topical finasteride different?
Short answer
Oral finasteride is swallowed, while topical finasteride is applied to the scalp. Topical finasteride can still enter the bloodstream and cause whole-body side effects. Compounded medications are prepared by a licensed pharmacy for one patient and are not FDA-approved. Your physician decides which form, if either, is appropriate.
Oral finasteride is a prescription tablet that is absorbed through the digestive system. FDA-approved finasteride tablets are available for male pattern hair loss. Topical finasteride is applied directly to the scalp, but some medicine can still enter the bloodstream. Applying it to the scalp does not remove the risk of sexual, mood, or other whole-body side effects.
There is no FDA-approved topical finasteride product. Compounded medications are prepared by a licensed pharmacy for one patient and are not FDA-approved. The FDA does not review each compounded formula for safety, effectiveness, or quality before it is marketed.
Topical products can also cause scalp irritation and can expose another person through contact with treated skin or spilled medicine. Follow the pharmacy's instructions for application, handwashing, drying, and safe storage.
A licensed physician in your state reviews your needs and risks before choosing a form. Do not switch between pills and topical treatment, combine them, or change the amount without your prescriber's guidance.
