01
Dates explained
Expiration date vs. beyond-use date
FDA explains that expiration dates reflect the period a drug is known to remain stable, meaning it retains strength, quality, and purity when stored as labeled. Compounded medications may also carry a beyond-use date assigned by the pharmacy. Do not treat either date as a suggestion.
An expiration date is the manufacturer's promise. A beyond-use date is the pharmacy's. Mix them up and you'll injure yourself slowly.
02
Storage variables
Common storage variables
- Temperature: some products require refrigeration, while others have different labeled conditions.
- Light: some compounds are light-sensitive and should remain in protective packaging.
- Time after opening or mixing: pharmacy instructions may change after puncture or preparation.
- Clean handling: storage does not fix contamination introduced during use.
03
If something's wrong
What to do if something goes wrong
If a package sits in heat, a vial freezes, the solution changes appearance, the label is unclear, or the beyond-use date has passed, contact the pharmacy before use. Do not try to rescue questionable medication with online advice.
04
Safe disposal
Safe disposal
For injectable supplies, use an appropriate sharps disposal container and follow local disposal rules. Do not put loose needles in household trash.
