Activella should not be used to prevent heart disease, heart attacks, strokes, or dementia. Estrogens, with or without progestins, have been shown to increase the risk of heart disease (including heart attack), stroke, dementia, serious blood clots (eg, in the lungs or legs), cancer of the uterus, and breast cancer in some women. Tell your doctor right away if you have unusual vaginal bleeding while you use Activella. Talk with your doctor if you have questions about the benefits and risks of using Activella.
Activella should be used for the shortest possible time at the lowest effective dose to minimize the risk of these side effects. Talk with your doctor regularly about your need to use Activella.
Activella is used for:
Treating certain moderate to severe symptoms of menopause (eg, hot flashes; dryness, itching, or burning in or around the vagina). It is also used to prevent osteoporosis (weakened bones) in certain women after menopause. It may also be used for other conditions as determined by your doctor.
Activella is a combination of estrogen and progestin hormones. It works by replacing natural progestin and estrogen in women who can no longer produce enough of these hormones.
Do NOT use Activella if:
- you are allergic to any ingredient in Activella
- you are pregnant or think you may be pregnant

- you have had recent (within the past year) bleeding in the brain, stroke, heart attack, or other serious blood vessel problems
Contact your doctor or health care provider right away if any of these apply to you.
