To ensure safety and effectiveness, Ethinyl Estradiol and Norelgestromin patches must be stored at room temperature in their original, sealed pouches. Used patches should be disposed of by folding them in half so the sticky sides adhere to each other, then placed in a trash receptacle that is inaccessible to children or pets.
Proper storage is essential for maintaining the medication's potency, while careful disposal is a critical safety measure to prevent accidental exposure to the powerful hormones remaining in a used patch.

Proper Storage: The Key to Effectiveness
How you store your patches before use has a direct impact on whether they will work as intended. The active hormones are sensitive to environmental conditions.
Keep it at Room Temperature
The patches must be stored between 15 and 30 degrees C (59 and 86 degrees F). Storing them in places that are too hot or too cold can degrade the hormones and reduce the patch's effectiveness.
Use the Original Pouch
Always keep each patch inside its sealed protective pouch until the moment you plan to apply it. This pouch shields the medication from light and moisture, which can also compromise its integrity.
Do Not Refrigerate or Freeze
Exposing the patches to extreme cold is just as damaging as extreme heat. A cool, dry place like a dresser drawer or a closet shelf is a much better location than a bathroom medicine cabinet, where heat and humidity fluctuate.
Safe Disposal: Protecting Others
A used patch still contains a significant amount of active hormones that can be absorbed through the skin. Disposing of it correctly is not just about cleanliness; it's a crucial safety step.
The Fold-and-Toss Method
Once you remove a patch, immediately fold it in half, pressing the sticky sides firmly together. This action seals the remaining medication within the patch, minimizing the risk of accidental contact.
Why This Method is Critical
Hormones like estrogen and progestin can be absorbed by anyone who touches the patch, including children and pets. This accidental exposure can be harmful. The "fold-and-seal" method is the first line of defense.
Secure the Trash
After folding the patch, throw it away in a secure trash can. Ensure the receptacle has a lid or is otherwise kept out of the reach of curious children and pets who might rummage through it.
Never Flush a Patch
Do not dispose of patches by flushing them down the toilet. The hormones can leach into the water system, posing a risk to the environment.
Common Pitfalls to Avoid
Simple mistakes in handling can undermine the medication's purpose or create unnecessary risks.
Avoiding Bathroom Storage
The bathroom is one of the worst places to store your patches. The steam and temperature changes from showers and baths create an unstable environment that falls outside the recommended storage conditions.
Disposing of Expired Medication
Unused patches should be discarded after their expiration date. Even if they are still in the pouch, the medication may no longer be effective. Dispose of them using the same fold-and-toss method to prevent accidental use.
Forgetting Key Safety Practices
Proper handling extends to how you use the medication. Remember to apply the patch to clean, dry skin on an approved area and to follow your prescribed schedule precisely. Discuss all related health factors, such as smoking or sun sensitivity, with your provider to ensure your overall safety.
A Simple Checklist for Safe Handling
Use these points to ensure you are managing your medication correctly at every stage.
- If your primary focus is ensuring the patch works correctly: Always store it in its original pouch at room temperature, away from heat and moisture, until you are ready to apply it.
- If your primary focus is protecting your family and pets: After use, immediately fold the patch in half with the sticky sides together and dispose of it in a secure trash can.
- If your primary focus is overall health and safety: Follow the application and removal schedule precisely, and maintain regular check-ups with your healthcare provider to monitor your health.
Following these simple storage and disposal protocols is a critical step in using this medication safely and effectively.
