Quick Answer: Refrigerated medications like insulin and biologics need storage between 2°C and 8°C to stay effective. Always check instructions and use a reliable fridge or cooler for proper storage!
There are many temperature-sensitive medications that need refrigeration to remain effective and safe to use. These include widely recognised treatments such as insulin, Ozempic, Mounjaro, Wegovy, Saxenda, Humira, Enbrel, various eye drops, growth hormones, EpiPens, and even specific vaccines to name a few.
But what does refrigeration mean for these medications? What specific temperature range should be maintained? How can you ensure they are stored correctly, whether at your local pharmacy or in your home fridge?

What’s the Ideal Refrigerator Temperature for Medications?
Most medicines that require refrigeration belong to a category called biologics. These innovative treatments contain living cells derived from plants, animals, or humans, making them both highly effective and highly sensitive to their storage conditions. Exposure to improper temperatures or light can cause these medications to degrade and lose their potency.
To maintain their effectiveness, biologics and other refrigerated medications must stay within precise temperature ranges. Any break in the cold chain, even briefly, can render them ineffective or unsafe to use.
If you’ve been prescribed a temperature-sensitive medication, particularly injectables, it’s vital to ensure your fridge is set to the correct temperature to protect their quality and effectiveness.

What Is the Ideal Fridge Temperature for Medications?
As a rule of thumb, medicines requiring refrigeration should be kept within a temperature range of 2°C to 8°C. However, it’s essential to check the specific requirements for each medication on the packaging or consult with your pharmacist to ensure optimal storage conditions are met.

How to Store Medications in Your Refrigerator
Maintaining a stable environment inside your fridge is crucial for preserving the quality of your medications. Here are several tips to help ensure your medications are stored safely and effectively:
- Avoid overloading your fridge. Overcrowding can block airflow, leading to uneven cooling.
- Minimise how long the fridge door is open to prevent temperature fluctuations.
- Keep medicines away from the freezer compartment, as temperatures can drop too low and freeze your medication.
- Store your medications in the central part of the fridge where temperatures are most consistent. Avoid door shelves, as these areas are subject to frequent temperature changes.
- Separate medications from food items to reduce the risk of contamination.
- Regularly check your fridge’s temperature using a thermometer to ensure it remains within the recommended range.
How Often Should You Check Your Fridge Temperature?
Pharmacies typically use specialised medical refrigerators equipped with built-in temperature monitoring systems. For home use, it’s advisable to check the temperature of your fridge regularly to ensure it’s functioning correctly and consistently maintaining the proper range.
Many patients use connected thermometers that can send temperature data to your smartphone. These devices provide alerts if the temperature goes outside the acceptable range, offering peace of mind for those storing sensitive medications.
How Long Can Refrigerated Medicine Be Left Out?
Fortunately, many refrigerated medications are designed to remain stable for some time at room temperature, making daily management somewhat easier. However, how long refrigerated meds can be left out varies depending on the specific medication. Below are some common examples:
- Insulin: Typically safe for up to 30 days at room temperature.
- Mounjaro: Stable for up to 21 days when not refrigerated.
- Wegovy: Can be left unrefrigerated for up to 28 days.
- Humira: Effective for up to 14 days outside of refrigeration.
- Aimovig: Maintains efficacy for 7 days at room temperature.
- Latanoprost eye drops: Remain stable for up to 6 weeks at room temperature.
- Dupixent: Can stay unrefrigerated for 14 days.
- Vaccines: Highly sensitive and typically remain stable for only a few hours at room temperature.
Always consult the manufacturer’s guidelines or your pharmacist for accurate storage instructions for your specific medication.
What Does Room Temperature Mean for Medications?
For medications, room temperature generally falls within a range of 8°C to 25°C. Ensure medications are stored in a cool, dry place, away from direct sunlight, heat sources, and humidity.
If transporting or storing medications during warm weather, consider using a portable medical-grade cooler to maintain the appropriate temperature range.
Tips for Keeping Medications Cool While Travelling
Travelling with refrigerated medications requires additional planning to prevent exposure to unsuitable temperatures. Here are some helpful tips:
- Invest in a medical-grade Mini Travel Fridge designed for medications.
- Keep medications in a shaded area, avoiding direct sunlight whenever possible.
- Use a connected thermometer to monitor the temperature inside your storage bag.
- Pack medications securely to prevent movement or damage during transit.
