Do Propecia pills have an expiration date?
Yes. Propecia (finasteride 1 mg) tablets are packaged with an expiration date. Like most prescription drugs, they’re expected to remain safe and effective only through that date if stored properly.
What happens if you take Propecia after the expiration date?
Using medication after its expiration date can mean the drug may be less effective, because the active ingredient can degrade over time. Expired tablets are also more likely to have packaging-related issues if they were exposed to heat, moisture, or light.
How can you tell whether your Propecia is still good?
Check the box and/or bottle label for the printed expiration date. If the tablets look unusual (discolored, crumbled, or the package has been damaged or exposed to moisture), don’t use them even if the date hasn’t passed—ask your pharmacist for advice.
Does the expiration date change if I split, store differently, or keep it longer than the bottle says?
The expiration date is tied to the product as manufactured and stored according to label conditions. Splitting tablets or storing them in a different container can increase exposure to air and humidity, which can shorten useful shelf life.
What should you do if your Propecia is expired?
Don’t take expired pills. Bring the bottle to a pharmacy to ask about safe disposal, and contact your prescriber for a replacement prescription if you need ongoing treatment.
