Storing Your GLP-1 Medication and Travelling With It

One of the most common questions we hear from patients is: "What happens if my medication isn't in the fridge for a few hours?"

The good news is that GLP-1 medications are generally more stable than many people realise. While proper storage is important, short periods outside the refrigerator do not usually mean your medication has been damaged.

This guide explains how to safely store your medication at home, what to do while travelling, and when medication may need to be replaced.

How Should I Store My GLP-1 Medication?

Most GLP-1 medications should be stored in the refrigerator before use. The recommended storage temperature is: 2°C to 8°C (36°F to 46°F). Your medication should ideally be kept:

• In its original packaging

• Away from direct sunlight

• Away from the freezer compartment

• Out of reach of children

  
  

Never freeze your medication. If a pen or vial has been frozen, it should not be used, even if it appears normal after thawing.

What If My Medication Was Left Out of the Fridge?

Many patients worry that a few hours outside refrigeration means their medication is no longer safe. In most cases, this is not true.

Current manufacturer guidance shows that medications such as Wegovy and Ozempic can remain stable at room temperature (below 30°C) for extended periods, provided they have not been exposed to excessive heat or freezing. For example:

• Wegovy can remain below 30°C for up to 28 days

• Ozempic can remain below 30°C for up to 56 days after first use

• Mounjaro may remain below 30°C for 21–30 days depending on the pen type and local prescribing guidance

  
  

This means that if your medication was left out overnight, during a day of travel, or was unrefrigerated for several hours, it is usually still safe to use.

Heat Is a Bigger Risk Than Room Temperature

The biggest threat to GLP-1 medications is excessive heat. Avoid leaving your medication:

• In a parked car

• Near windows in direct sunlight

• On hot outdoor surfaces

• In checked airline luggage

• Near heaters or heat sources

  
  

Temperatures above 30°C can reduce medication effectiveness and may damage the active ingredient. If you're unsure whether your medication has been exposed to excessive heat, contact the Medara clinical team.

Travelling With GLP-1 Medication

Travelling with your medication is usually straightforward with a little preparation.

Domestic Travel

For short trips:

• Keep medication in your carry-on bag

• Avoid leaving it in a hot car

• Use an insulated travel pouch if travelling in warm weather

Most patients do not require special refrigeration during short journeys.

Flying With GLP-1 Medication

You can take GLP-1 medications on a plane. We recommend:

• Packing medication in your carry-on luggage

• Keeping it in its original packaging when possible

• Bringing enough medication for your trip, plus extra in case of delays

Do not place medication in checked luggage, where temperatures may become excessively hot or cold.

International Travel

When travelling overseas:

• Check local temperature conditions

• Carry medication in your hand luggage

• Consider an insulated medication travel case for long journeys

• Keep a copy of your prescription if required

If travelling for an extended period, ensure you have enough medication available before departure.

Do I Need a Medication Cooler?

Not always. For most day-to-day travel, an insulated pouch is sufficient. Cooling cases can be helpful when:

• Travelling in very hot climates

• Spending extended periods outdoors

• Taking long-haul flights

• Travelling where refrigeration access may be limited

The goal is to prevent overheating rather than keeping the medication ice-cold.

Signs Your Medication May Have Been Damaged

Do not use your medication if:

• It has been frozen

• The solution appears cloudy when it should be clear

• You notice particles floating in the solution

• The pen appears damaged

• It has been exposed to extreme heat

If you're unsure, contact Medara before administering your next dose.

Frequently Asked Questions

My medication arrived slightly cool rather than cold. Is that okay?

In many cases, yes. GLP-1 medications can generally tolerate short periods outside refrigeration during transport, provided they remain within manufacturer temperature limits and are not exposed to excessive heat.

I left my pen out overnight. Do I need to throw it away?

Usually not. A single night at normal room temperature is unlikely to affect the medication.

Can I put my medication back into the fridge after taking it out?

In most situations, yes. However, storage guidance varies slightly between medications and pen types. If you're unsure, follow the instructions supplied with your medication or contact the Medara clinical team.
