Medications are among the most important — and most perishable — supplies in a shelter. Heat, light, humidity, and time all degrade them. Storing them properly, and planning for refills and cold-chain items, is what keeps them effective when a pharmacy is not an option.

Control the four enemies
The same enemies that spoil food degrade medicine: heat, light, moisture, and oxygen. Store medications in a cool, dark, dry place in their original light-proof, sealed containers. A stable closet in the climate-controlled part of your shelter, kept dry with a dehumidifier, dramatically extends usable life.
Understand expiration dates
Expiration dates are conservative, and many stable medications retain potency well beyond them — but some do not, and a few can be unsafe past date. Never guess: consult a pharmacist about which of your specific medications store well and which must be strictly rotated.
Cold-chain medications
Insulin and some other drugs require refrigeration, which is a serious challenge off-grid. A portable medical refrigerator running off your battery bank, with solar backup, is the usual solution. If anyone in your group depends on a cold-chain medication, this is a top-priority design problem — plan the power for it first.
Build a rotation system
Track what you have, its date, and its storage needs. Use the oldest first and replace as you go, exactly like food rotation. Talk with your doctor about maintaining a reasonable emergency supply of essential prescriptions, and keep a written list of everyone's medications and doses in your grab-and-go documents.
Vitals and monitoring
For managing chronic conditions without regular checkups, basic monitoring tools help you catch problems early: a Pulse Oximeter for blood oxygen and a Blood Pressure Monitor for blood pressure are cheap, compact, and genuinely useful.
