For most households, emergency preparedness is primarily about food, water, and safety. For households where someone depends on prescription medications, medical equipment, or ongoing treatment, preparedness involves an additional layer of planning that most generic guides don’t cover.
A 72-hour power outage is manageable for a household with no medical dependencies. For a household where someone uses a home oxygen concentrator, an insulin pump, or a medication that requires refrigeration, that same 72 hours requires a specific plan. And a major regional disaster — the kind where utilities may be down for weeks — requires thinking far beyond what most people have considered.
This guide is for households where medical needs are part of the equation.
Start With a Complete Medical Inventory
Before you can plan, you need a clear picture of what you’re planning around. Write down, for every member of your household:
- All prescription medications: name, dosage, prescribing doctor, pharmacy
- Any over-the-counter medications used regularly
- Medical equipment used at home: CPAP, oxygen concentrator, nebulizer, infusion pump, power wheelchair, hearing aids, dialysis equipment
- Any conditions that require temperature management, regular treatment, or specialist access
- Allergies and adverse reactions
Store this document in your go-bag in a waterproof sleeve. Keep a digital copy in cloud storage or emailed to yourself. First responders and emergency medical personnel will need this information — having it written down and accessible is significantly better than trying to recall it under stress.
Building a Medication Supply Buffer
Insurance systems are designed around 30-day refill cycles. Emergencies don’t respect those cycles. Building even a small buffer of critical medications requires planning ahead, but it’s achievable for most people.
Practical strategies:
- Refill at day 25, not day 30. If you consistently refill before you run out, you naturally build a 5-day buffer. Over several months, that buffer can grow.
- Ask your doctor for a written emergency supply letter. Some physicians will provide a letter stating the medical necessity of having a 7–14 day emergency supply. This can support insurance coverage exceptions in some cases.
- Discuss disaster preparedness explicitly with your prescriber. Many physicians are aware of these challenges and have solutions — a slightly larger supply, a mail-order option that provides 90-day supplies, or coordination with your pharmacy for emergency dispensing protocols.
- For 90-day mail-order supplies: If your insurance covers mail-order pharmacy, a 90-day prescription leaves you naturally ahead of a 30-day cycle. Consider this for maintenance medications.
Medication Storage During Emergencies
Heat-Sensitive Medications
Many medications — insulin, certain biologics, eye drops, and others — require refrigeration. A power outage puts these at risk.
Options for refrigerated medications during an outage:
- Insulated coolers with ice packs: Most refrigerated medications can tolerate 24–48 hours at room temperature before degrading. A quality insulated cooler with gel packs can extend viable storage significantly.
- Portable power stations with a small medical fridge: Compact 12V coolers and portable power banks (1,000Wh+) can keep a small refrigerator running for several hours.
- Know your medication’s specific tolerance: Ask your pharmacist what the acceptable temperature range and duration is for your specific medication. The answer varies significantly and is often more forgiving than people assume — or stricter. Know before you need to.
All Medications
Store a supply of all critical medications in your go-bag, rotating to maintain current expiration dates. Heat, humidity, and light degrade medications — the go-bag should be stored somewhere temperature-stable, not in a hot car or a damp garage.
Power-Dependent Medical Equipment
Home medical equipment that requires electricity presents a specific planning challenge. Address each category:
CPAP / BiPAP
Most modern CPAP machines can run from 12V DC power, which means a portable power station or a vehicle can power them. A 10,000–20,000 mAh battery specifically marketed for CPAP use can provide one to several nights of use. Check your machine’s power requirements and invest in a compatible battery.
Oxygen Concentrators
Concentrators draw significant power and typically cannot run on small portable stations for extended periods. Options: backup oxygen tanks for short-term use during outages, coordination with your oxygen supplier about emergency protocols, and registration with your utility company as a medical baseline customer (which prioritizes your household for restoration).
Power Wheelchairs and Mobility Devices
Keep batteries charged above 80% routinely. Have a plan for manual evacuation if the chair cannot move. Know whether your chair can be charged from a vehicle outlet.
Infusion Pumps, Dialysis, and Complex Equipment
For households with life-critical equipment, connect directly with your medical supplier and your county emergency management office. Many counties maintain medical needs registries for exactly this purpose — registering ensures that first responders know your household’s situation and that utility restoration prioritizes your area when possible.
Register with Your Local Utility and Emergency Management
Both PGE/Pacific Power (Oregon) and Puget Sound Energy (Washington) maintain medical baseline and life support programs. Registering identifies your household as having critical power needs, which can influence restoration priority and may provide advance notification of planned outages.
Your county emergency management office may also maintain a Special Needs Registry or Access and Functional Needs (AFN) program. These registries help emergency managers plan for residents who will need additional assistance during disasters. Registration is voluntary and confidential.
Evacuation with Medical Equipment
If you need to evacuate, medical equipment comes first in the load-out. Establish in advance:
- What absolutely must come with you
- What can be left and replaced or borrowed
- Whether your evacuation destination can support your medical needs
- Whether you need to pre-identify a medical-needs shelter rather than a general population shelter
Talk to your healthcare team about evacuation scenarios. Many home health agencies have emergency plans and can be a resource during regional disasters.
Managing medical needs in an emergency is more complex than basic preparedness, but it’s plannable. The time to work through these questions is now, with your doctors and pharmacists, not in the middle of a crisis. Have questions about a specific medical situation?
