What is the “expiration date” on Descovy?
Descovy (emtricitabine/tenofovir alafenamide) comes with an expiration date printed on the bottle label or outer packaging. That date is the manufacturer’s guarantee for potency and safety when stored as directed (typically at controlled room temperature and kept in the original container).
Is “expiration” the same as patent or exclusivity expiration?
No. An “expiration date” on a drug package refers to the product’s shelf life. A patent or exclusivity expiration refers to when other manufacturers may be allowed to market competing versions of the drug. These are different timelines and are not interchangeable.
What happens if a patient takes Descovy after the printed expiration date?
Using any medication past its printed expiration date can mean potency may decline. If a dose is missed or storage conditions were poor, patients should contact their prescriber or pharmacist for guidance on whether to continue with existing supplies or replace them.
How can I find the right expiration date for the specific bottle I have?
Check the label or carton for:
- “EXP” (or “Expiration”) followed by a month/year, and
- the specific lot number (often helpful if there’s a recall or storage issue).
If you share the exact “EXP” text from your package (month/year), I can help interpret what it means.
