Estradiol
Women's health and hormonesAlso known as Estrace, Climara
Estradiol replaces the estrogen your body stops making at menopause, easing hot flashes, night sweats, and vaginal dryness. It works — often dramatically. But it carries FDA boxed warnings: small increased risks of blood clots, stroke, and, with certain regimens, breast and uterine cancer. If you still have your uterus, you'll usually take a progestin alongside it to protect the uterine lining. The guiding idea: the lowest dose for the shortest time that works, revisited with your doctor regularly.
How to take it
When
Pills are usually daily; patches are changed on a schedule — follow your exact prescription.
Food
Pills can be taken with or without food — with food if it upsets your stomach.
Avoid
Smoking raises the clot and stroke risk — this is a strong reason to quit.
Good to know
This is an ongoing conversation with your doctor — recheck each year whether you still need it.
Missed a dose?
Take it as soon as you remember, unless it's almost time for the next dose — then skip the missed one. For patches, apply a new one as soon as you remember and stay on your usual change day. Never double up.
