IMPORTANT PRESCRIBING INFORMATION


Subject: Change in recommended storage conditions for CombiPatch® (estradiol/ norethindrone acetate transdermal system)


Dear Health Care Provider,

Noven Pharmaceuticals, Inc. would like to inform healthcare professionals of the change in storage conditions for CombiPatch® (estradiol/norethindrone acetate transdermal system) 0.05/0.14 mg/day and 0.05/0.25 mg/day, as approved by the U.S Food and Drug Administration (FDA). The new storage condition requires to only “store CombiPatch in the refrigerator at 2°C to 8°C (36°F to 46°)”. Previous CombiPatch storage conditions allowed for the product to be stored as follows: “Prior to dispensing to the patient, store refrigerated 2°C to 8°C (36°F to 46°F). After dispensing to the patient, CombiPatch can be stored at room temperature between 20°C to 25°C (66°F to 77°F) for up to 6 months”.

The change in the storage condition for CombiPatch from up to 6 months at room temperature between 20°C to 25°C (66°F to 77°F) to fully refrigerated between 2°C to 8°C (36°F to 46°F), is not due to a product change. Recent analyses of test results showed that storage of CombiPatch in refrigerated conditions of 2°C to 8°C (36°F to 46°F) lead to improvement of product adhesion.

Starting December 2021, healthcare professionals are advised to inform their patients of the revised storage conditions and to ensure that the product is stored according to the new instructions: CombiPatch should be kept in refrigerated storage conditions (2°C to 8°C (36°F to 46°)) in its sealed foil pouch until the patient is ready to apply the transdermal system.

Please be advised that starting August 2022, patients will see changes on the outer packaging of CombiPatch reflecting these storage condition changes. Until then, we advise you to proactively inform any patient receiving CombiPatch of its new storage conditions.
