Do ED Pills Expire? Viagra, Cialis, BlueChew and Minoxidil Dates

This guide covers where the date comes from, what the FDA says about expired medicine, how each label says to store the product, and what to do with old pills. Labels were read on DailyMed on 14 November 2026. We do not give doses.

Where the expiration date comes from

The date is not a guess. Federal rules say a drug "shall bear an expiration date determined by appropriate stability testing" (eCFR: 21 CFR 211.137, expiration dating, read 14 November 2026). Stability testing means the maker stores the product and checks over time that it still holds the right amount of drug.

The same rule ties the date to storage: "Expiration dates shall be related to any storage conditions stated on the labeling". So the date only counts if you keep the pills the way the label says.

The FDA explains its history and purpose. "In 1979, the U.S. Food and Drug Administration began requiring an expiration date on prescription and over-the counter medicines." It calls the date "a critical part of deciding if the product is safe to use and will work as intended." You will find it on the bottle, the blister pack or the carton, "sometimes following 'EXP.'"

A pharmacy that repacks pills into its own bottle may print its own date. Mail-order ED programs usually ship in the pharmacy's bottle, so check that label rather than looking for the maker's box.

What happens to an expired ED pill

The FDA lists two problems: "Expired medical products can be less effective or risky due to a change in chemical composition or a decrease in strength" (FDA: Don't be tempted to use expired medicines).

For an ED pill, "less effective" is the most likely result. A weaker pill may simply not work. That can lead a man to take more than prescribed, which is how side effects such as headache, flushing and low blood pressure become more likely. Do not make up for an old pill by taking extra.

You may have read that the military tests old drugs and extends their dates. That is true, but it does not apply to your bathroom cabinet. The FDA says the Shelf-Life Extension Program covers "certain federally stockpiled medical materiel" and works only after "select products undergo periodic stability testing conducted by FDA" (FDA: Expiration dating extension, read 14 November 2026). Those stockpiles are stored under controlled conditions and tested lot by lot. A bottle in a damp bathroom is neither.

Does Viagra expire? Does sildenafil expire?

Yes, both brand Viagra and generic sildenafil carry a date. The Viagra label's storage line is: "Store at 25°C (77°F); excursions permitted to 15-30°C (59-86°F)" (DailyMed: Viagra label, revised 11/2023). In plain words: room temperature, with short spells a little cooler or warmer allowed.

MedlinePlus adds the practical part for sildenafil tablets: "Store the tablets at room temperature and away from excess heat and moisture (not in the bathroom)" (MedlinePlus: sildenafil, read 14 November 2026).

The label does not print a set number of years. Each bottle's own date is the one that counts.

Does Cialis expire?

Yes. Brand Cialis and generic tadalafil have the same room-temperature rule. The Cialis label says "Store at 25°C (77°F); excursions permitted to 15-30°C (59-86°F)" and "Keep out of reach of children" (DailyMed: Cialis label, revised 3/2026).

MedlinePlus gives the same advice for tadalafil: keep it "in the container it came in, tightly closed, and out of reach of children" and away from heat and moisture (MedlinePlus: tadalafil, read 14 November 2026).

Daily tadalafil users get through a bottle fast, so expiry is rarely an issue. As-needed users who order a large pack are the ones who end up with old pills.

Does BlueChew expire?

Yes. BlueChew tablets are compounded, which means a pharmacy mixes them for each order rather than a drug maker producing them in bulk. BlueChew's FAQ says: "The medications offered through BlueChew are compounded. The FDA does not approve or evaluate the safety or effectiveness of compounded medications" (BlueChew FAQ, read 14 November 2026).

That FAQ does not state a shelf life. The date that counts is the one the compounding pharmacy prints on your pack. Compounded products are not covered by the maker's stability testing behind an FDA-approved tablet, so do not assume they last as long as a generic. If the pack has no date you can read, ask the pharmacy before using it. Our BlueChew cost guide lists its plans.

Does minoxidil expire?

Yes. Over-the-counter minoxidil foam and liquid carry an expiration date like any drug. The Kirkland Signature 5% solution label says "store at 20° to 25°C (68° to 77°F). Keep tightly closed" (DailyMed: Kirkland Signature minoxidil 5% solution, read 14 November 2026). The same label warns "Flammable: Keep away from fire or flame", because the liquid contains alcohol.

Oral minoxidil tablets, which some hair loss programs prescribe, also carry a date on the pharmacy bottle. A liquid that has changed color, smell or thickness should not be used even before its date.

How each product should be stored

The FDA's general tip fits all of them: "it is better to store medicine in a cool, dry place such as a dresser drawer, storage box, closet shelf, or kitchen cabinet", away from the stove and sink. It names "a damp bathroom cabinet" as the kind of place that can weaken a medicine before its date.

What to do with expired ED pills

Do not keep them "just in case". The FDA says "A drug take-back location, or pre-paid drug mail-back envelope, are the preferred ways to dispose of expired, unwanted, or unused medicine." Many pharmacies have a drop box. If none is near, the FDA's page explains how to throw most medicines in the household trash safely.

Then get a fresh supply. The cheapest way is usually an FDA-approved generic with the visit included, which also lets a clinician check that the drug still suits you.

What a fresh supply costs

Generic sildenafil starts at $1.60 a dose at Strut Health, and generic tadalafil at $1.80 a dose at Rex MD, visit included, as checked November 14, 2026. Every plan is on our ED price page, and programs are ranked on Best online ED programs. For hair loss, see the hair loss price page.
