Finasteride vs dutasteride: What pregnancy and handling precautions apply?

Both medicines affect hormones needed for the normal development of a male fetus. They should not be used during pregnancy. If you can become pregnant, discuss that with a licensed physician before considering either drug for any form of hair loss. Treatment decisions require a careful, individual review.

Someone who is pregnant or may become pregnant should not handle crushed or broken finasteride tablets. Intact tablets have a coating that limits contact with the drug during normal handling. Dutasteride can be absorbed through the skin, so leaking capsules should not be handled by someone who is pregnant or may become pregnant.

If accidental contact occurs, wash the area with soap and water and contact a healthcare professional for advice. Do not open dutasteride capsules or crush tablets unless your pharmacist gives specific instructions.

Topical products can leave medicine on skin, hands, or surfaces. Ask how to prevent transfer to another person. Compounded medications are prepared by a licensed pharmacy for one patient and are not FDA-approved. Keep all forms stored safely away from children and follow blood donation restrictions for your prescribed medicine.
