Dupixent Storage: How Long Can It Stay Out of the Fridge?

Understanding Dupixent Storage: A Guide for Patients

Dupixent, with the active ingredient dupilumab, is a crucial medication for managing several chronic conditions, including severe atopic dermatitis, asthma, and other inflammatory diseases. For the medication to remain effective and safe, proper storage is paramount. This guide provides clear, practical advice for patients in India on how to store Dupixent, particularly concerning its temperature requirements and how long it can be kept at room temperature.

Why Proper Storage Matters for Dupixent

Medications like Dupixent are sensitive to temperature fluctuations. Deviating from recommended storage conditions can compromise the drug's stability and efficacy. This means it might not work as well as it should, or in some cases, it could become unsafe to use. Understanding these guidelines ensures you get the full benefit of your treatment.

Refrigeration: The Long-Term Storage Solution

The primary recommendation for storing Dupixent is in the refrigerator. This ensures the medication remains stable over extended periods. The ideal temperature range for refrigeration is between 36°F and 46°F (2°C to 8°C). It's essential to keep Dupixent in its original carton. This packaging serves a dual purpose: it protects the medication from light, which can degrade it, and it clearly displays the expiration date, a critical piece of information.

Tips for Refrigerating Dupixent:

• Consistent Temperature: Ensure your refrigerator maintains the recommended temperature range. Avoid placing Dupixent near the freezer compartment, as accidental freezing can damage the medication.
• Avoid Freezing: Never freeze Dupixent. If there's any suspicion that the medication has been frozen, it should not be used.
• Original Packaging: Always store Dupixent in its original carton.
• Expiration Date: Regularly check the expiration date on the packaging and use the medication before it expires.

Room Temperature Storage: When and How Long?

There are situations where you might need to take Dupixent out of the refrigerator, such as before self-injection. In such cases, Dupixent can be kept at room temperature, but with strict limitations. The recommended room temperature is at or below 77°F (25°C). Under these conditions, you can keep the medication out of the fridge for a maximum of 14 days.

Guidelines for Room Temperature Storage:

• Time Limit: Use the Dupixent syringe or pen within 14 days of removing it from the refrigerator.
• Temperature Control: Ensure the room temperature does not exceed 77°F (25°C).
• No Re-Refrigeration: If a Dupixent syringe or pen has been removed from the refrigerator and reached room temperature, it should not be returned to the refrigerator.
• Use or Discard: After 14 days at room temperature, or if the temperature has exceeded the limit, the medication must be discarded.

Preparing for Injection: Warming Up Dupixent

To make the injection more comfortable, it's often recommended to let Dupixent reach room temperature before administration. The time needed for warming varies slightly by strength:

• 300 mg/2 mL: Allow approximately 45 minutes to warm up.
• 200 mg/1.14 mL: Allow approximately 30 minutes to warm up.

Important: Allow Dupixent to warm up naturally. Never attempt to speed up the process by using a microwave, hot water, or direct sunlight. These methods can damage the medication.

When Dupixent is No Longer Safe or Effective

The U.S. Food and Drug Administration (FDA) advises against using any medication, including Dupixent, past its expiration date. Furthermore, Dupixent is considered unsafe or ineffective if:

• It has been frozen.
• It has been kept at room temperature for more than 14 days.
• It has been exposed to temperatures above 77°F (25°C) for an extended period.
• The medication appears discolored or contains particles (though visual inspection is not always definitive).

If you are unsure about the storage or condition of your Dupixent, it is always best to err on the side of caution and consult your healthcare provider or pharmacist.

When to Consult a Doctor
