Does Aczone (dapsone) expire like other medicines?
Yes. Aczone has an expiration date printed on the package or prescription label, and it can lose potency after that date. Using it past expiration is generally not recommended.
What does “Aczone expires” mean in practice?
“Expires” usually refers to the manufacturer’s expiration date for the specific product strength and formulation (for example, the 5% gel). Once that date passes, the drug may become less effective, and the product’s quality can’t be guaranteed.
How can you tell if your Aczone is still okay to use?
Check the expiration date on:
- The box or tube label (for the gel), or
- Your prescription label (if it lists a separate date).
If the product is past its expiration date, has changed color/texture, or looks damaged, it should not be used.
Does opening the tube affect expiration?
Opening doesn’t automatically reset the expiration date printed by the manufacturer. The labeled expiration date still applies. If your pharmacist gave a “discard after” date, follow that instead.
What should you do if your Aczone is expired?
Ask your pharmacist or prescriber about:
- Getting a replacement prescription, and
- Whether a different formulation or alternative acne treatment is appropriate.
If you tell me whether you have Aczone gel (5%) or another form, and what the date on your tube says, I can help you interpret what to check.
