Frequently Asked Questions

CombiPatch helps to treat moderate to severe hot flashes, night sweats and vaginal dryness associated with menopause by providing a continuous flow of hormones through the skin directly to the bloodstream. If you use CombiPatch only to treat dryness, itching and burning in or around the vagina, talk with your healthcare professional about whether a topical vaginal product would be better for you.

CombiPatch is made specifically for women who still have their uterus. If you've had your uterus removed, ask your doctor about Vivelle-Dot^® (estradiol transdermal system), an estrogen-only Delivery Optimized Thermodynamics (DOT) Matrix^® technology patch. For important safety information, including Boxed Warning, about Vivelle-Dot, click here.

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
• May be pregnant

Talk to your doctor about what treatment option may be right for you.

CombiPatch is the only transdermal combination hormone therapy that utilizes DOT Matrix^® Technology. This patented delivery system releases both estradiol (a form of estrogen like your body's own) and norethindrone acetate (a progestin) continuously upon application to your skin. This does not mean that CombiPatch is safer or more effective than hormone therapy pills. DOT Matrix^® Technology allows the medication to be absorbed through your skin and into your bloodstream over 3 to 4 days.

A small transparent patch, CombiPatch uses the patented DOT Matrix^® technology delivery system to allow hormones to be absorbed directly into your bloodstream through your skin. That's why CombiPatch can help to treat moderate to severe symptoms associated with menopause with smaller total doses compared to pills that need to be first digested and then metabolized. This does not mean that CombiPatch is safer or more effective than hormone therapy pills.

CombiPatch is available in two dosage options (reflected in two patch sizes). This allows your doctor to make adjustments to your treatment (specifically your progestin level) according to your symptoms and any side effects you may be experiencing.

CombiPatch was the first patch in the U.S. to deliver both estrogen and progestin. CombiPatch was created with an innovative technology called Delivery Optimized Thermodynamics (DOT) Matrix^® that allows it to be small and transparent for a discreet appearance.

CombiPatch is a small transparent round patch that comes sealed in a protective pouch. In clinical studies, CombiPatch was shown to have excellent skin adhesion and a low level of skin irritation.

CombiPatch is worn on the lower abdomen. (See how.)

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 patch should be worn at a time during each half-week time period.

CombiPatch should be replaced twice a week, 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. You can choose the days of the week you change patches.

You should remove the old patch and apply a new one to a new area of the lower abdomen as soon as you remember. No matter what day this happens, you should stick to the twice-a-week schedule for the next patch.

Contact with water when bathing, swimming or showering should not affect the patch as long as it is not rubbed when washing. The patch should not be exposed to the sun for prolonged periods of time.

Women on the Continuous Combined regimen with CombiPatch often experience irregular bleeding or spotting during the first year of treatment. This can occur with any combination hormone therapy regimen. 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 (1.3 on an intensity scale of 1 [light] to 4 [heavy]). Talk to your doctor about any issues you have with spotting. He or she may be able to help by adjusting your treatment plan.

Women on the Continuous Sequential regimen with CombiPatch and Vivelle-Dot^® (estradiol transdermal system) receive a consistent level of estrogen throughout the 4-week schedule, but progestin during only half of the schedule. They often experience regular, monthly bleeding, similar to your natural monthly period. Ask your doctor any questions you have about bleeding.

There are several different forms of hormone therapies, including patches, pills and emulsions. While all hormone therapies have similarities, there are differences in dosage strength, delivery (patch, pill, gel, emulsion, or vaginal ring), indication (used for the treatment of menopause symptoms, such as vaginal dryness or hot flashes, and/or for osteoporosis prevention), regimen (combination therapy, estrogen-only therapy) and frequency (every day, twice a week, etc). Some therapies include a combination of hormones, while others may be estrogen or progestin only.

Some women are fine without any therapy. But women who are bothered by moderate to severe symptoms might want to consider treatment. Hormone therapy is the most effective treatment available for hot flashes. It also helps treat night sweats and vaginal dryness.

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.

Women without a uterus who have moderate to severe symptoms associated with menopause can be treated with estrogen only. Women who still have a uterus should be treated with estrogen plus progestin. Adding progestin helps prevent cancer of the uterus.

Hormone therapy has not been shown to cause permanent weight gain. Some women experience temporary weight gain due to water retention. Increasing fluid intake, limiting salt consumption and regular exercise help reduce water retention. A slowing metabolism, common as people age, should be accounted for in reduced calorie intake and regular exercise. Hormone therapies are not indicated for the treatment of weight loss.

It is recommended that women who use hormone therapy to help manage their moderate to severe symptoms associated with menopause use the lowest effective dose for the shortest time. Different solutions are right for different women, depending on each woman's health history, current symptoms and personal preferences. You and your doctor should regularly discuss if you still need treatment with hormone therapy. Together you can make the right choice for you.
