Can they be used together?

Whether to combine treatments is a clinical decision and neither label addresses the other product. This page reports what each label states separately.

Which one works better?

The labels do not compare them, they were approved on separate evidence, and this page does not rank them.

Is minoxidil available for women?

Yes. There are separate approved products for women with their own Drug Facts labels and their own concentrations and directions.

Contraindications	Propecia PROPECIA is contraindicated in the following: Pregnancy. Finasteride use is contraindicated in women when they are or may potentially be pregnant. Because of the ability of Type II 5α-reductase inhibitors to inhibit the conversion of testosterone to 5α-dihydrotestosterone (DHT), finasteride may cause abnormalities of the external genitalia of a male fetus of a pregnant woman who receives finasteride. If this drug is used during pregnancy, or if pregnancy occurs while taking this drug, the pregnant woman should be apprised of the potential hazard to the male fetus.

02Written by us

One is a prescription tablet, the other is bought off the shelf

Finasteride is a prescription tablet taken once daily, and it is documented in a full prescribing information document. Topical minoxidil is sold over the counter under a Drug Facts label, applied to the scalp, and the two documents are not even the same kind of document.

That difference shows up throughout this comparison: prescription labels list contraindications and drug interactions, while Drug Facts labels list what to do and when to stop.

03Written by us

They are approved for different populations

The Propecia label states that finasteride is indicated in men only and is not indicated for use in women. Topical minoxidil is approved for both men and women, as separate products with their own labels, formulations and directions.

04Written by us

Both labels say the effect depends on continued use

The Propecia label states that continued use is recommended to sustain benefit and that benefit should be re-evaluated periodically. The minoxidil label states that continued use is necessary to increase and keep hair regrowth, and that hair loss will begin again otherwise. On this point the two documents agree.

05Written by us

The safety sections are not comparable

Finasteride's label lists sexual adverse reactions and is contraindicated in pregnancy, with a warning about handling broken tablets. The minoxidil Drug Facts label lists local scalp effects and systemic signs that should prompt stopping the product. Because one is a systemic tablet and the other is applied to the scalp, these lists are not two versions of the same thing.
