How to store Mounjaro in the fridge

Monday, October 7, 2024

Woman putting items in fridge

Mounjaro is a popular weight loss injection. It's a prescription medication that's gaining attention for its effectiveness.

However, like many medications, proper storage of Mounjaro is important. This prevents the medicine from breaking down, causing it to either stop working or not work as well as it should.

Mounjaro must be stored in the fridge until first use.

This article will cover:

  • When to put Mounjaro in the fridge
  • How to store Mounjaro before first use
  • How to store Mounjaro after first use
  • What your Mounjaro should look like
  • How to travel with Mounjaro

Do I have to put Mounjaro in the fridge?

Yes, but only until you first use it. Mounjaro should be stored in the refrigerator to maintain its potency (how well it works). The recommended temperature control range is between 2°C and 8°C (36°F and 46°F).

It's important to avoid temperature fluctuations, which can affect Mounjaro's effectiveness. A fridge thermometer can help monitor the temperature if you’re worried, but it isn’t essential.

Here are some tips for ensuring Mounjaro tirzepatide is kept at a stable temperature:

  • Keep weight loss drug Mounjaro in its original packaging until first use.
  • Avoid storing it in the fridge door where temperature varies the most.
  • Keep it away from the freezer compartment to prevent freezing.

Contact us with any questions or doubts about Mounjaro storage.

Before first use: Does Mounjaro have to stay cold?

Before using Mounjaro for the first time, check the strength and expiration date on the packaging. The pharmacy will have checked this too before sending your medicine to you.

Also, keep the Mounjaro pen in its original packaging until you use it. This protects it from light and moisture, which can degrade the medication. Once you’ve used your pen, you don’t have to keep it in the box but always store it with the lid firmly on as light causes the medicine to start to break down.

After first use: Can I keep Mounjaro at room temperature?

Once you've started using your Mounjaro pen, you can keep it at room temperature for 30 days. The medicine will stay effective for this long when stored at room temperature.

Some people prefer to store their pen in the fridge even once they’ve started using it. This is also fine, but we recommend you take it out 15 minutes before your injection.

This is because injecting a liquid straight from the fridge can sting or be uncomfortable.

What should Mounjaro look like?

If the liquid in your Mounjaro pen looks cloudy, discoloured, or has particles (bits) floating in it, you should check with the pharmacy that supplied it. These changes could indicate that the medication is no longer safe to use.

The liquid should be clear with no bits and look like water.

Mounjaro shelf life: How long can it last in the fridge?

The shelf life of Mounjaro in the fridge depends on several factors. Generally, unopened Mounjaro can last up to 24 months in the fridge if stored correctly. However, always check the expiration date on the packaging and the Mounjaro patient information leaflet.

Once opened, Mounjaro should be used within a month. After this period, its effectiveness may decrease, so keep track of when you first opened the medication.

Do I have to keep Mounjaro cold when travelling?

Consider using a portable cooler or insulated medical bag to maintain the recommended cold storage temperature for unopened pens while travelling. Once pens have been opened or used, it’s probably easier to keep them at room temperature for the 30 days they last, this should not affect how well they work.

Avoid exposing Mounjaro to direct sunlight or extreme heat. Try to keep it in a cool, shaded place and at a stable temperature. Your hotel room is ideal.

Understanding Mounjaro and its importance in weight loss

Mounjaro is a prescription medication used to treat obesity. One of a group of medicines called GLP-1 receptor agonists, it is used as part of a weight loss plan that includes a balanced diet and regular exercise.

The weekly weight loss injection is available to people with a body mass index (BMI) over 30. The medication mimics a hormone that targets areas of the brain that control blood sugar levels and regulate appetite, leading to the user eating less and losing weight.
