In This Guide
Yes, condoms expire. Latex and polyisoprene condoms typically last three to five years from the manufacture date; polyurethane lasts about five years; lambskin lasts about one year. Spermicidal condoms expire roughly a year sooner than their non-spermicidal equivalents because the N-9 spermicide degrades faster than the latex. The printed date on each wrapper is the absolute outside limit, but real-world shelf life depends heavily on storage. Heat, friction, sunlight, and humidity all shorten condom life dramatically, sometimes by years. This guide covers exactly how long condoms last, where to store them, and how to tell when one has gone bad.
Shelf Life by Material
- Latex (lubricated, no spermicide): 4 to 5 years from manufacture.
- Latex (with spermicide): 3 years from manufacture (N-9 degrades faster than latex).
- Polyisoprene (like SKYN): 3 to 5 years.
- Polyurethane: 5 years.
- Lambskin: about 1 year.
- Latex (non-lubricated, no spermicide): 5 years.
How to Read the Date
The expiration date is printed on every individual wrapper and on the outer box. The format is usually YYYY/MM or MM/YYYY (some brands print only the year and month, not a specific day). The condom is good through the end of that month.
What you sometimes also see:
- "EXP" or "USE BY" followed by a date — this is the expiration date.
- "MFG" followed by a date — this is the manufacture date, not the expiration. Add the shelf life of the material to get the expiration.
- A lot number for tracking — not a date, ignore for shelf life purposes.
How Storage Affects Real Shelf Life
The printed date assumes correct storage. Bad storage shortens shelf life dramatically. The main enemies of condoms:
Heat
Latex begins to degrade above 100°F (38°C). Storage in a hot car (which can hit 140°F inside on a summer day), a glove box, near a heater, or in direct sunlight all destroy condoms quickly. A condom stored in a hot car for one summer is functionally expired regardless of printed date.
Friction and Pressure
A condom carried loose in a wallet or back pocket is subject to friction every time you sit down. The wrapper can wear through, and even an intact wrapper does not protect the latex from compression. A condom in a wallet for a few weeks should be considered expired.
Sunlight
UV light breaks down latex. Storage on a windowsill or in any direct-light area shortens shelf life.
Humidity
Less critical than heat and friction, but extreme humidity can affect condoms over time. Storage in a steamy bathroom is suboptimal.
Cold
Less harmful than heat. A condom stored in a cool place is generally fine. Avoid freezing if possible.
Where to Store Condoms
Good storage spots:
- Nightstand drawer (cool, dark, accessible).
- Bathroom medicine cabinet (assuming not above a steamy shower).
- Closet shelf in a cool room.
- Travel toiletry kit (for short trips only, not extended hot-weather travel).
Bad storage spots:
- Wallet or back pocket.
- Car glove box (subject to heat).
- Car center console.
- Beach bag in direct sun.
- Above a heater or warm appliance.
- Windowsill or anywhere with direct sunlight.
Signs a Condom Has Gone Bad
Before using, check each condom:
- Wrapper looks crushed, torn, or punctured: throw it out.
- Wrapper feels flat (no air bubble): the seal is broken; throw it out.
- Past the expiration date on the wrapper: throw it out.
- Latex feels sticky, brittle, or discolored: it has degraded; throw it out.
- Latex has a noticeably strong or rancid smell: it has degraded; throw it out.
- Wrapper has been carried in a wallet/glove box/hot environment: assume expired regardless of printed date.
Condoms are cheap; replacement risk is high. When in doubt, use a fresh one.
Bulk Buying and Expiration
For households buying in bulk (like the Trojan ENZ 40-piece bowl 40-piece bowl or the Trustex Assorted Colors Bulk Case of 1,000 1,000-piece case), check the expiration date before buying and try to use the box within the dated range. For very large purchases, store extras in a cool, dark place and rotate stock so the oldest get used first.
Manufacturers typically ship product with two to three years of shelf life remaining. If you receive a box with less than a year remaining, that is unusual; contact the seller.
Spermicidal Condom Caveats
Spermicidal condoms (like Trojan Stimulations Ultra Ribbed with Spermicide, Trojan Ultra Thin Armor with Spermicide, or Trojan ENZ with Spermicide 3-pack) have a shorter shelf life than non-spermicidal because N-9 degrades faster than latex. About three years versus four to five for non-spermicidal. Check the date carefully and use within the dated window. See Specialty Condoms: Glow, Warming & Spermicidal for the broader N-9 discussion.
What If You Use an Expired Condom?
Expired condoms are more likely to break or leak, but using one is not certain failure. If you have used an expired condom and want to assess risk:
- For pregnancy: emergency contraception is available over the counter and most effective within 72 hours of unprotected sex.
- For HIV exposure concern: PEP (post-exposure prophylaxis) is most effective started within 72 hours.
- For STI testing: talk to a clinician about appropriate testing windows.
Frequently Asked Questions
How long do unopened condoms last?
Three to five years from manufacture date for latex and polyisoprene, one year for lambskin, about three years for latex with spermicide. The exact expiration date is printed on every wrapper.
Can I use a condom one month past the expiration date?
Possibly, but the failure risk is elevated. Condoms are cheap and replacement is easy. Use a new one whenever possible.
How long does a condom last in a wallet?
Far less than the printed date suggests. Body heat and friction degrade latex quickly. Treat any wallet-stored condom older than a few weeks as expired.
Does refrigerating condoms make them last longer?
No meaningful benefit. Storage in a cool, dry place is plenty. Refrigeration is not necessary.
How can I tell if a condom is still good?
Check the wrapper for an air bubble (seal intact), check the expiration date, and check the latex itself for color, smell, and texture changes. If anything looks off, use a new one.
