Attached is an article that discusses the governments study into how long medications will really last.
122 medications were tested – likely those that are held in the US governments Strategic National Stockpile for use in a national emergency. The average extension of medications that were tested was 66-278 months past the manufacturers expiration date.
This study is important as it discusses and lists some over the counter medications you could possible store for future uses.
Read the attached article and store medications wisely.
Bottom line is that there is NO guarantee that any medication will retain its potency past its expiration date.
Those studied in the SLEP one could buy without a prescription are:
MEAN EXTENSION TIME (mo.)
- Diphenhydramine (Benadryl) – syringe-needle (Pill form was NOT studied) (76)
- Cimetidine (Tagamet) – tablets (67)
- Guaifenesin (Mucinex) – ER tablets (85)
- Povidone-Iodine – ointment (65)
- Povidone-iodine – solution (74)
- Acetaminophen pseudoephedrine – capsules (24)
- Naproxen (Aleve) – tablets (52)
Hope this helps.
