How to Store Semaglutide: Refrigeration, Travel, and Shelf Life

Storing semaglutide correctly is one of the simplest things you can do to protect your treatment. Improper storage can reduce the medication’s effectiveness — and since each vial represents a meaningful investment, it’s worth getting right.

Refrigerate before first use

Compounded semaglutide should be kept in the refrigerator at 36°F to 46°F (2°C to 8°C) until you open or first use the vial. Store it upright, away from the freezer compartment and away from direct light.

Never freeze semaglutide. Freezing can damage the medication and make it unsafe to use.

After first use

Once you have drawn your first dose, many compounded semaglutide formulations can remain at room temperature (up to 77°F / 25°C) for up to 28 days. Always refer to the specific storage instructions on your medication label, as formulations vary.

If in doubt, keeping it refrigerated throughout is always the safer choice.

Traveling with semaglutide

Flying or road-tripping with your medication is straightforward with a little preparation:

• Air travel — injectable medications are TSA-permitted in carry-on bags. Carry your prescription or a letter from your provider in case of questions.
• Road trips — use an insulated travel case with a gel ice pack. Avoid leaving medication in a parked car, especially in warm weather.
• International travel — check the destination country’s rules on importing prescription medication before you go.

Signs your medication may be compromised

Inspect your semaglutide before each injection:

• The solution should be clear and colorless to slightly yellow
• Do not use it if it appears cloudy, discolored, or contains particles
• Do not use it past the expiration date

If you are unsure whether your medication is still good, contact your pharmacy or care team rather than guessing. With Renlo, your semaglutide treatment includes ongoing access to a care team for exactly these questions.

A note on compounded vs. brand-name storage

Storage guidelines for compounded semaglutide may differ slightly from brand-name versions like Ozempic or Wegovy. Always follow the specific instructions provided with your compounded medication, as formulations and preservatives can vary.
