ACTIVELLA® FAQs
What is hormone therapy (HT)?
Hormone therapy consists of the use of prescription drugs most often used when treating menopause symptoms. It encompasses both estrogen therapy (ET) and estrogen plus progestin therapy (EPT). HT replaces the more dated term hormone replacement therapy (HRT).
What is ACTIVELLA® used for?
ACTIVELLA® is used after menopause to:
- Reduce moderate to severe hot flashes
- Help reduce your chances of getting osteoporosis (thin weak bones)
- If you use ACTIVELLA® only to prevent osteoporosis from menopause, talk with your doctor about whether a different treatment or medicine without estrogens might be better for you.
ACTIVELLA® 1.0 mg/0.5 mg is also used after menopause to:
- Treat moderate to severe dryness, itching, and burning in and around the vagina
Who should not take ACTIVELLA®?
