Activelle and Activelle LD are used to treat moderate to severe vasomotor symptoms (uncomfortable feelings of heat, sweating and flushing) that can occur as a result of low estrogen levels associated with menopause. Activelle is also used to treat vulval and vaginal atrophy (changes in the vagina or external genitalia as a result of low estrogen levels associated with menopause) with symptoms such as itching, burning, dryness in or around vagina, difficulty or burning while urination, and pain while having sex. The estrogen hormone is called estradiol (E2) and helps to relieve your menopausal symptoms. Estradiol is identical to the estrogen produced naturally by your body. Activelle replaces the estrogen in your body, which decreases naturally at menopause. The progestin hormone is called norethindrone acetate (NETA) and helps to reduce the risk of endometrial hyperplasia (stimulation of growth of the lining of the uterus), which could lead to cancer of the lining of the uterus (womb). Activelle and Activelle LD should be used only in women with intact uterus. Activelle and Activelle LD should be used only under the supervision of a doctor, with regular follow-up at least once a year to identify side effects associated with its use. Your first follow-up visit should be within 3to 6 months of start of treatment. Your visit may include a blood pressure check, a breast exam, a Pap smear and pelvic exam. You should have a mammogram before starting treatment and at regular intervals as recommended by your doctor. Your doctor may recommend some blood tests. You should follow the instructions of the doctor who prescribed Activelle to you. Activelle and Activelle LD is supplied in calendar dial packs of 28 white tablets. Take one tablet once daily. Try to take the medication at the same time each day. Once you have finished all the 28 tablets in the pack, start a new pack continuing the treatment without interruption.
