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.

Reference information, not medical advice

This page is a reference, not medical advice. It reports what the FDA-approved label states and links to that label. It does not tell anyone what to take, and it cannot replace a conversation with a doctor or pharmacist who knows the person's history.

Finasteride and topical minoxidil are the only two ingredients with an FDA approval for pattern hair loss. Everything else discussed for hair loss is either approved for something else or not approved at all. This page compares the two labels.

Warnings and precautions	PROPECIA is not indicated for use in women or pediatric patients. Women should not handle crushed or broken PROPECIA tablets when they are pregnant or may potentially be pregnant due to potential risk to a male fetus. PROPECIA causes a decrease in serum PSA levels. Any confirmed increase in PSA while on PROPECIA may signal the presence of prostate cancer and should be evaluated, even if those values are still within the normal range for men not taking a 5α-reductase inhibitor. 5α-reductase inhibitors may increase the risk of high-grade prostate cancer.

Contraindications	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. In female rats, low doses of finasteride administered during pregnancy have produced abnormalities of the external genitalia in male offspring.	you are a woman your amount of hair loss is different than that shown on the side of this carton or your hair loss is on the front of the scalp. 5% minoxidil topical solution is not intended for frontal baldness or receding hairline. you have no family history of hair loss your hair loss is sudden and/or patchy you do not know the reason for your hair loss you are under 18 years of age.

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

Written by us

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.

They are approved for different populations

Written by us

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.

Both labels say the effect depends on continued use

Written by us

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.

The safety sections are not comparable

Written by us

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.
