Key Takeaway: A power outage does not always mean refrigerated medication must be discarded, but safe storage depends on the medication and the conditions it experienced. Before a storm, members should confirm product-specific guidance with their pharmacist and make a plan to keep medications cold without freezing them.
Storm season has a way of testing every plan we make. Across the U.S. and here in Puerto Rico, most of us know the checklist by heart: water, batteries, gas for the generator, cash on hand. But one item rarely makes the list, and it may be the most important thing in your house: the medication sitting in your refrigerator.
Insulin, GLP-1s, certain eye drops, and many liquid antibiotics all depend on staying cold, typically between 36°F and 46°F. When the power goes out, a clock starts. The good news? With a little planning, you can protect your treatment through almost any outage.
Here's what the FDA and CDC recommend.
Before the storm arrives
The best time to make a medication plan is while the sky is still clear. Start by asking your pharmacist how long each of your refrigerated medications can safely stay at room temperature. The answer varies more than you'd expect. Some products are stable for weeks, others for only a day or two.
If a storm is on the way, check your supply. If a refill is already due, don't wait. Pharmacies get crowded fast once a storm has a name. And if you're worried about running low during an extended outage, call your plan's member services team before assuming anything. Refill timing rules exist to protect both members and plans, and whether an exception applies during a declared emergency depends on your specific benefit.
Finally, keep a cooler and a few gel packs ready, and store a current list of your medications, doses, and prescribers in a waterproof bag. If you ever need a replacement supply from an unfamiliar pharmacy, that list will save you real time.
When the lights go out
Keep the refrigerator door closed. According to the CDC, an unopened fridge holds a safe temperature for about four hours. For a short outage, doing nothing at all may be your best move.
If the outage stretches longer, move your medications to a cooler with ice or gel packs, but never let them touch the ice directly. Freezing permanently damages many medications, and a product that's been frozen generally shouldn't be used. A towel or the original packaging placed between the medication and the ice is all it takes.
Many refrigerated medications also have more room-temperature flexibility than people realize. Insulin, for example, can sit between 59°F and 86°F for up to 28 days per FDA guidance, and several biologics and injectables have similar windows. The label or your pharmacist can tell you exactly how long. Heat is the bigger enemy: keep medications out of direct sunlight and away from anything that runs warm, like a car dashboard or a windowsill.
The concern isn't that warm medication becomes harmful to take. It's that heat steadily drains potency, so your treatment can quietly stop working as well as it should.
After the power comes back
The CDC recommends replacing any refrigerated medication once the power has been out for a day or more, unless the label says otherwise. Once pharmacies reopen and properly stored medication is available again, swap out anything that spent the outage warm, even if it seems to be working fine.
Your pharmacist is part of your storm plan
If you're ever unsure whether a medication is still good, don't guess. Call your pharmacist. Manufacturers also run support lines that can tell you whether a specific product survived the conditions it was exposed to.
