Verbatim response from Perplexity
Yes, but only if you buy it from a legitimate pharmacy with a prescription. Finasteride is a prescription medicine, and sources that offer it online through a clinician visit or valid prescription—such as GoodRx Care, Blink Health, DiRx Health, and HealthWarehouse—describe it as prescription-only and FDA-approved in its generic form.[3][6][8][1]
The main safety issue is where you buy it, not the fact that it’s online. The U.S. FDA warns that topical finasteride from compounded pharmacies is not FDA-approved and has been linked to serious side effects; products sold without a prescription are also risky and may be illegal.[2][4]
What to look for in a safe online purchase:
- Requires a prescription or an online medical consultation.[3][4][6][8]
- Uses a licensed U.S. pharmacy and states the product is FDA-approved generic finasteride.[6][8][1]
- Provides clear side-effect warnings and clinician/pharmacist access.[1][3][6]
- Does not sell finasteride “over the counter” without medical review.[4][7]
What to avoid:
- Sites selling finasteride without a prescription.[4][7]
- Compounded topical finasteride unless a clinician has specifically discussed the risks, since the FDA has warned about potential serious harms and lack of FDA approval for those formulations.[2]
Safety-wise, finasteride can cause sexual side effects and other adverse effects, and it should not be used by pregnant women or handled by them if tablets are crushed/broken because of fetal risk.[1][3][6]
