How does CombiPatch work?

CombiPatch is an alcohol-free patch that releases both estradiol (an estrogen) and norethindrone acetate (a progestin) continuously upon application to your skin. This patch technology allows the medication to be absorbed into your skin in a predictable manner over 3 ½ days.

What is the role of progestin in hormone therapy?

Clinical studies show that the addition of progestin to an estrogen treatment for at least 12 days per cycle reduces, but does not eliminate, the incidence of enlargement of benign tumors of the uterus (fibroids) and the potential risk of cancer of the uterus in women with an intact uterus. The addition of progestin to an estrogen treatment has not been shown to interfere with the effectiveness of hormone therapy for its approved uses.

How is CombiPatch technology different from other hormone therapy patches?

CombiPatch was the first patch in the U.S. to deliver both estrogen and progestin. CombiPatch was created with an innovative technology called DOT Matrix that allows it to be the smallest combination patch available.

What does CombiPatch look like and how well will it adhere to my skin?

CombiPatch is a small clear, discreet patch that comes sealed in a small protective pouch. In clinical studies, CombiPatch was proven to have excellent skin adherence with a complete adherence rate of 90 percent. Furthermore, patients reported that there were fewer than four days per year when their patch failed to adhere.

Can there be a reaction to the adhesive?

There has been a very low incidence of skin reactions reported with the use of CombiPatch. In clinical studies of 2,500 postmenopausal women, only 6 percent discontinued use of the product due to application-area reactions over the course of one year. Generally, reactions will include skin irritation, redness or rash at the area of the CombiPatch application.

What should be done if the patch falls off?

If your patch falls off, the same patch can be reapplied to another area of your lower abdomen. If necessary, a new patch can be applied, and the original treatment schedule should be continued. Only one system should be worn at a time during the 3 ½ day wear period

How often is the patch changed?

CombiPatch should be replaced twice weekly, and the new patch should be placed on a different skin area. The areas of application should be rotated, with at least one week allowed between applications to the same spot. CombiPatch should be placed on a smooth (fold-free), clean, dry area of the skin.

What should I do if I forget to change my patch?

In this case, you should remove the old patch and apply a new one to a new spot as soon as you remember. No matter what day this happens, you should stick to the twice-a-week schedule for the next patch.

What is the effect of water and sunlight on CombiPatch?

Contact with water when bathing, swimming or showering should not affect the patch as long as it is not rubbed when washing. However, soaking in a hot tub for a long time should be avoided as this can cause the patch to come off. The patch should not be exposed to the sun for prolonged periods of time.

Will I begin to get my period again if I start using CombiPatch?

While on hormone therapy, you might experience irregular bleeding or spotting. Over the course of a one-year study with CombiPatch, this bleeding and spotting stopped in the majority of women. Women who experienced bleeding usually characterized it as light. Rarely are these side effects serious enough to stop therapy.

What are the side effects associated with CombiPatch?

CombiPatch is made for menopausal women with an intact uterus. Some patients may experience side effects. Most are usually temporary and disappear over time. They include breast pain, vaginal bleeding and headaches. You should not use hormone therapy if you are pregnant because of possible risk to the fetus. When you speak with your health care provider, be sure to discuss your personal or family history of breast lumps, abnormal vaginal bleeding, abnormal blood clotting, severe headache, or dizziness. While on hormone therapy, if you experience any abnormal symptoms, such as leg or chest pain or vision changes, please contact your health care provider immediately as these symptoms may indicate serious life threatening illnesses such as heart attack or blood clots.

WHAT IS THE MOST IMPORTANT INFORMATION I SHOULD KNOW ABOUT COMBIPATCH (A COMBINATION OF ESTROGEN AND PROGESTIN HORMONES)?

Do not use estrogens and progestins to prevent heart disease, heart attacks, strokes or dementia (decline in memory and thinking skills). Using estrogens with progestins may increase your chances of getting heart attacks, strokes, breast cancer, and blood clots, and may increase your risk of dementia.

Do not use CombiPatch if you have had your uterus removed (hysterectomy). CombiPatch should not be used if you have unusual vaginal bleeding; currently have or have had certain cancers, including cancer of the breast or uterus; had a stroke or heart attack in the recent past (for example, in the past year); currently have or have had blood clots; currently have or have had liver problems; or think you may be, or know that you are, pregnant.

The most common side effects that may occur with CombiPatch are breast pain, vaginal bleeding, and headache.

CombiPatch is used after menopause to: reduce moderate to severe hot flashes; treat moderate to severe dryness, itching and burning in or around the vagina; and treat certain conditions in which a young woman’s ovaries do not produce enough estrogens naturally. If you use CombiPatch only to treat your dryness, itching and burning in or around the vagina, talk with your health care professional about whether a topical vaginal product would be better for you.

You and your health care professional should talk regularly about whether you still need treatment with CombiPatch and whether you are taking the lowest dose that works for you.
