Insulin that must stay cold, oxygen concentrators, home dialysis, CPAP machines — all of them assume the outlet works and the pharmacy can order. In a short outage, neighbors and hospitals absorb the shock. In a long one, that assumption fails quietly and then all at once.

A short outage can be absorbed because the hospital is still a hospital and the pharmacy’s supplier is still delivering. A long one fails the assumption that those backstops are infinite. Each device dies in a private room, on a shared clock. The emergency department is a plan for a bad night, not for a city whose outlets, deliveries, and staff homes are dark together.

The practical step is unglamorous: ask the clinician what a week without power does to the specific device or drug, keep a written dose list, and know the nearest facility that has its own generation. A freezer brick and a small cooler plan beat a vague hope that “they” will prioritize you.

A drug that must stay cold is a storage problem inside the medical problem. The vial in a warm drawer is not a plan. A cooler and a freezer brick, rotated while the power was on, are a plan with a limit you should learn before you need it. Ask the clinician what a week does to that specific drug or device. A box label is not that conversation.

This is not a reason to hoard someone else’s medication. It is a reason to treat your own care plan as infrastructure.

Write the dose list for a stranger with a flashlight: name, dose, schedule, allergies. Phones hold this well until they do not. The nearest facility with its own generation is not a guaranteed bed. It is a more real destination than a clinic whose refrigerator and dispenser died with the feeder. Put the address on the same paper as the doses.

Other people’s medication is not a backup supply. Your own care is the infrastructure you can actually arrange. Pills, cold storage, oxygen, dialysis, and a machine that only works when plugged in are different problems. If the device is the care, the power for that device is the care. Say the steps out loud to the person who would be in the house.
