Does Mounjaro Need to Be Refrigerated?

Mounjaro, a medication for type 2 diabetes and weight loss, requires careful storage to remain effective. Many users ask, does Mounjaro need to be refrigerated?

This article explains Mounjaro’s storage requirements, handling tips, and what to do if storage conditions are compromised.

What Is Mounjaro?

Mounjaro is an injectable drug containing tirzepatide. It’s FDA-approved for type 2 diabetes and often used off-label for weight loss. The medication comes in single-dose pre-filled pens.

Proper storage ensures Mounjaro works as intended. Incorrect handling can reduce its potency. Understanding storage rules is key for users.

Official Storage Guidelines

Does Mounjaro need to be refrigerated? Yes, Mounjaro pens should be stored in a refrigerator at 36°F to 46°F (2°C to 8°C). This keeps the drug stable until its expiration date.

Pens must be kept in their original carton to protect from light. Freezing is not allowed, as it damages the medication. Always check the label for details.

Room Temperature Storage

Mounjaro can be stored at room temperature, up to 86°F (30°C), for up to 21 days. This is helpful for travel or missed refrigeration. After 21 days, unused pens must be discarded.

Keep pens away from heat sources, like stoves or car dashboards. Room temperature storage is a temporary option. Refrigeration is preferred for long-term use.

Why Refrigeration Is Important

Mounjaro contains sensitive proteins that can degrade if not stored properly. Refrigeration at 36°F to 46°F maintains the drug’s chemical stability. This ensures it effectively controls blood sugar or supports weight loss.

Improper storage, like exposure to heat or freezing, can reduce potency. Consistent refrigeration prevents these issues. It’s a simple way to protect your medication.

What Happens If Mounjaro Freezes?

Freezing Mounjaro can damage its proteins, making it less effective. The liquid may appear cloudy or contain particles after freezing. Using frozen Mounjaro could lead to poor blood sugar control or reduced weight loss.

If a pen freezes, don’t use it. Contact your pharmacist or doctor for a replacement. Eli Lilly advises against using frozen pens.

What Happens If Mounjaro Gets Too Warm?

Exposure to temperatures above 86°F (30°C) can harm Mounjaro. Prolonged heat may break down tirzepatide, reducing its effectiveness. The pen may still look normal, but potency could be compromised.

If a pen gets too warm, consult your pharmacist. They may recommend discarding it. Proper storage prevents heat-related damage.

Note: Follow manufacturer guidelines for safe storage.

How to Store Mounjaro in the Refrigerator

Store Mounjaro pens in the refrigerator’s main compartment, not the door or near the freezer. Use a thermometer to ensure the temperature stays between 36°F and 46°F. Place pens in their original carton to block light.

Avoid overcrowding the fridge, which can affect cooling. Check the temperature regularly, especially after power outages. This keeps Mounjaro safe and effective.

Traveling with Mounjaro

Traveling with Mounjaro requires planning to maintain proper storage. Use an insulated cooler with gel packs kept at 36°F to 46°F. Avoid frozen gel packs, as they can freeze the pens.

For short trips, room temperature storage (up to 86°F) is fine for 21 days. Always carry pens in their carton. Check local pharmacy options for emergencies.

Tips for Safe Travel

To protect Mounjaro while traveling, follow these steps:

• Use a cooler with a thermometer to monitor temperature.
• Keep pens in a carry-on bag, not checked luggage.
• Avoid leaving pens in hot cars or cold trunks.

These precautions ensure Mounjaro stays effective. Plan ahead for long trips.

What to Do If Storage Conditions Are Compromised

If Mounjaro is exposed to improper temperatures, don’t use it without guidance. Contact your pharmacist or doctor to assess the pen. They may recommend discarding it and getting a replacement.

Keep the pen for inspection but avoid injecting it. Eli Lilly’s customer service can provide further advice. Quick action prevents treatment disruptions.

Replacing Damaged Mounjaro

If Mounjaro is damaged by heat or freezing, you’ll need a replacement. Contact your pharmacy to discuss options. Some insurance plans cover replacements, but coverage varies.

Without insurance, a new supply costs $1,000–$1,300 monthly. Ask about Lilly Cares or other assistance programs. Keep records of the incident for claims.

Costs Without Insurance

Mounjaro’s retail price is $1,000–$1,300 for a 28-day supply of four pens. Improper storage, like freezing, means losing a costly medication. Annual costs can exceed $15,600 without coverage.

Discounts from GoodRx or SingleCare lower prices to $990–$1,025. Lilly’s Savings Card may apply for commercial insurance but not Medicare. Explore savings to offset replacement costs.

How to Check Mounjaro for Damage

Inspect Mounjaro pens before use. Look for cloudiness, particles, or discoloration in the liquid. A stiff or jammed pen mechanism may indicate freezing.

If anything seems off, don’t inject. Contact your pharmacist for advice. Regular checks prevent using compromised medication.

Storing Mounjaro at Home

At home, designate a specific fridge spot for Mounjaro, away from the freezer. Use a container to organize pens and prevent mishandling. Label the area to avoid confusion with food or drinks.

Monitor the fridge temperature weekly with a thermometer. This ensures Mounjaro stays within 36°F to 46°F. Consistent storage maintains effectiveness.

Power Outages and Storage

Power outages can disrupt refrigeration, risking Mounjaro’s stability. Keep pens in a cooler with gel packs at 36°F to 46°F during outages. Avoid opening the cooler unnecessarily to maintain temperature.

If power is out for over a day, contact your pharmacist. They can advise on whether the pens are still usable. Act quickly to protect your supply.

Manufacturer Guidance

Eli Lilly, Mounjaro’s maker, provides clear storage instructions. Pens must stay refrigerated at 36°F to 46°F and never frozen. Room temperature is allowed for 21 days, but heat above 86°F is harmful.

Lilly’s website and packaging detail these rules. Contact their customer service at 1-800-545-5979 for storage concerns. They may assist with damaged pens.

Pharmacies and Proper Storage

Pharmacies store Mounjaro under strict conditions before dispensing. They keep pens refrigerated and monitor temperatures. If you suspect a pharmacy mishandled your prescription, ask about their storage practices.

Choose a reputable pharmacy to ensure quality. Return damaged pens for inspection. This protects your treatment and investment.

Impact of Improper Storage

Using improperly stored Mounjaro can reduce its effectiveness. For diabetes, this may lead to unstable blood sugar. For weight loss, progress may slow or stop.

Replacing damaged pens disrupts treatment and adds costs. Proper storage prevents these issues. Follow guidelines to stay on track.
