If a prescription must stay refrigerated, the best time to decide what happens during a power outage is before the refrigerator warms up. Write down the medicine name, its labeled storage requirements, where backup cooling supplies are kept and which pharmacy or manufacturer number you will call if the outage lasts longer than expected.
CDPH emphasizes following manufacturer requirements for refrigerated medications. FDA likewise warns that temperature-sensitive drugs can lose potency when refrigeration is interrupted. The correct next step depends on the exact product, how warm or cold it became and how long it was outside its recommended conditions.
Quick Answer
Before a summer power outage, identify every medicine that requires refrigeration and keep its label and storage instructions available. Have an insulated cooler or other backup method ready only if it can maintain the product’s required conditions without freezing it. During an outage, avoid repeatedly opening the refrigerator. Record when the power failed and, when possible, the medication-storage temperature. After power returns, do not use a food-safety time rule to decide whether medicine is usable. Contact the pharmacist or manufacturer with the exact product, time and temperature information.
Make the Refrigerated Medication Plan Before an Outage
Start by identifying which prescriptions actually require refrigeration. Keep the medication name, strength, dosage form and storage wording together with the pharmacy contact information.
FDA emergency guidance recommends knowing how much medication is on hand and having cooling supplies ready for medicines that need refrigeration.
Do not wait for an outage to learn that a medicine must not freeze or has a limited room-temperature allowance.
01
Know the Medication
- Medication name, strength and dosage form.
- Labeled refrigeration and freezing instructions.
- Manufacturer or pharmacy contact information.
02
Know the Backup Plan
- Insulated cooler or approved transport container.
- Cooling packs when appropriate for the medicine.
- Thermometer and a way to record outage times.

Not sure how your prescription should be kept cold during an outage?
La Quinta Pharmacy can review product-specific storage information and help you prepare the questions and exposure details needed for a power-outage plan.
What to Record When the Power Comes Back On
When power returns, note the time and check the refrigerator temperature before it cools back down, when that can be done safely.
Write down the approximate outage duration, the highest or lowest observed temperature and whether the medicine was moved to another container or cooling source. Keep the original label and package.
If no thermometer was available, say so. The pharmacy or manufacturer may still be able to help using the outage duration and product-specific information.
What to Do if the Medication Was Outside Its Recommended Conditions
Do not decide from appearance alone. A refrigerated medicine can look normal even when temperature exposure may have affected potency or stability.
Contact the pharmacy, healthcare provider or manufacturer with the medication, strength, storage conditions and exposure time.
Do not automatically discard an essential medicine before getting guidance when replacement is not immediately available.
If the outage also interrupts an electrically powered medical device or creates another medical emergency, follow the device plan and call 911 when emergency care is needed.
A June Power-Outage Checklist for Refrigerated Prescriptions
Use this list before extreme heat or a planned outage affects home refrigeration.
- Identify every refrigerated prescription. Keep the exact storage wording with the medication.
- Check whether freezing must be avoided. Do not assume direct contact with ice is appropriate.
- Prepare backup cooling supplies. Use a cooler, gel packs and thermometer only in a way that fits the product instructions.
- Record when the outage begins. Keep a simple written or phone note of the time.
- Keep the refrigerator closed when possible. Avoid unnecessary door opening while power is out.
- Record temperature information. Note readings before the refrigerator cools back down after power returns.
- Do not apply food rules to medicine. Use the exact product’s stability and storage information.
- Call after uncertain exposure. Give the pharmacist or manufacturer the medication name, outage duration and temperature details.
Frequently Asked Questions
How long can my refrigerated medicine stay safe during a power outage?
There is no single time limit for every refrigerated medicine. The answer depends on the exact product, temperature and duration of exposure.
Should I move refrigerated medicine to a cooler as soon as the power goes out?
Not automatically. Keeping the refrigerator closed may help maintain cold conditions, and moving a product incorrectly can expose it to freezing. Follow the product-specific plan.
Can I put refrigerated prescriptions directly on ice packs?
Do not assume so. Some products can be damaged by freezing. Ask how the exact medicine should be separated from cooling packs.
Does the four-hour food rule apply to refrigerated medications?
No. Food-safety time limits do not determine medication stability. Use the exact medicine’s labeled and manufacturer-supported storage information.
What information should I record after an outage?
Record the outage start and end times, available temperature readings, whether the medicine was moved and the cooling method used.
Can La Quinta Pharmacy review a refrigerated medication after a power outage?
Yes. The pharmacy can review appropriate product-specific storage information and explain when manufacturer or prescriber follow-up is needed.
Make the Cold-Storage Plan Before the Refrigerator Loses Power
A power-outage plan for refrigerated prescriptions should be specific to the medicine. Know its storage requirements, prepare backup cooling carefully, record outage conditions and ask for product-specific guidance before deciding whether an exposed medicine should be used or replaced.
For official guidance, review CDPH’s medication refrigeration guidance, CDPH’s power-outage safety guidance, and FDA’s safe drug use after a natural disaster.
This article provides general medication-storage information. Storage limits differ by product. Ask the pharmacist, prescriber or manufacturer the question appropriate to their role and call 911 for a medical emergency.
