My doctor gave me scripts for Cipro, said stored in the refrigerator it would keep almost indefinitely. Said it was one of the best broad spectrum to store for this purpose.
He also had me get some prescription antibiotic ointment for use with MRSA infections. That is also now stored in the frig.
And ALWAYS keep a 12 month supply of any essential medicines you have to take. If you have to pay more to get the quantity because insurance will only cover 30 days at a time, tough, spend the money and do it. I have 18 months of my heart meds, and I keep it at that level. Ditto for the wife’s BP meds.
I have “LOST” prescriptions and had to get a duplicate....(thyroid)....so I could get a bit ahead in case of emergency. I don’t know why, when the FEDS tell us to stock up on needed prescriptions that the docs/pharms don’t just allow them.
