Drugs don't last long but they're all religiously marked with expiration dates. Insulin is dead a day or two after the fridge warms up, same with withdraw medications, injected inoculations.

Inhalers, hypoxia arresters and Epi Pens and contraceptives last about a year. A lot of Antibiotics start go go after a year, some last a bit longer. I remember mood stabilizers having a short shelf-life but that could be old information.

Pain killers and fever remedies, anti-inflamatories, flu remedies last much longer than their expiration date, probably up to a decade. They just get weaker.

Scalpels, tongue depressors, clamps, forceps, thermometer covers, all that examination and surgery business, comes in individually plastic wrapped packs. Even towels are sterilized and sealed in bundles. You could raid a hospital under water and come up with perfectly find surgical tools.
