Does Activella cause weight gain?

Activella (estradiol/norethindrone acetate) is a brand-name medication containing a form of estrogen (estradiol) and progesterone (norethindrone acetate). It is used to treat postmenopausal women with symptoms such as night sweats, hot flashes, and vaginal dryness that are due to low estrogen levels. It can also be used to prevent osteoporosis in women who have reached menopause.

While weight loss is also a reported side effect, it is more common to see weight gain. In clinical studies, up to 9% of people taking Activella reported weight gain. It is not known if the medication was the cause of the increase in weight. In fact, there is little evidence that most types of HRT make you gain weight. You can gain some weight during menopause and as you get older, and this often happens whether you take HRT or not. Exercising regularly and eating a balanced diet should help you to manage your weight. It is also important to note that the medication can also cause your body to hold onto fluids (fluid retention), which can look like swelling or weight gain. If you notice any rapid weight gain while taking Activella, call your healthcare provider to discuss if this medication is right for you.
