What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

    Description

    CombiPatch is a patch that contains a combination of hormones used to treat women with a uterus who suffer from menopausal symptoms, vaginal atropy due to menopause, and low estrogen levels caused by hypogonadism, castration, or primary ovarian failure.

    Estradiol and norethindrone acetate are the hormones in CombiPatch.

    CombiPatch is available in the following strengths:

    • 0.05 mg estradiol with 0.14 mg norethindrone acetate
    • 0.05 mg estradiol with 0.25 mg norethindrone acetate

    Directions

    Carefully read and follow the instructions that come with your prescription. Use CombiPatch as your doctor has prescribed. If you have any questions, talk to your doctor or pharmacist.

    Application

    CombiPatch should be applied to smooth, clean, dry, and intact skin of the lower abdomen. Do not place the patch on or near the breasts or at the waistline where it could be rubbed off by clothing. You should rotate the application sites, allowing at least one week between applications to the same site. You should wear only one patch at a time during the 3- or 4-day dosing interval. Avoid exposing the patch to the sun for long periods of time.

    Removal

    Slowly remove the patch. If there is adhesive remaining, allow your skin to dry for 15 minutes, then gently rub the area with an oily cream or lotion to remove the residual adhesive.

    Storage
    CombiPatch systems should be stored in their sealed foil pouches in the refrigerator between 36°F and 46°F. Keep CombiPatch away from children and pets.

    Ingredients

    Estradiol and norethindrone acetate are contained in each CombiPatch transdermal system.

    Contraindications

    Cautions

    CombiPatch has a FDA Boxed Warning against the use of estrogens and progestins for preventing cardiovascular disease or dementia. The FDA Boxed Warning also warns that estrogen plus progestin therapy can increase the risk of blood clots in the legs or lungs, stroke, and heart attack in postmenopausal women. Further, the FDA Boxed Warning warns that estrogen plus progestin therapy can increase the risk of dementia and breast cancer in women. Estrogen alone has been shown to increase the risk of endometrial cancer in women with a uterus. Estrogen alone has also been shown to increase the risk of stroke, blood clots, and dementia in postmenopausal women. Estrogens with or without progestins should be used at the lowest dose possible and for the shortest duration of time while meeting treatment goals.
