What is Activelle?
Activelle is a medication that combines both estradiol (identical to the natural hormone estrogen) and progestin in a single tablet.
It’s used as a treatment for:
- Moderate to severe vasomotor symptoms (hot flashes, flushing, sweating), which are associated with lower estrogen levels brought on by menopause
- Vulval and vaginal atrophy and associated symptoms occurring due to menopause
Activelle should only be used in women that have an intact uterus.
For more resources, including a full list of the risks and benefits of Activelle, please review the product monograph.
How does Activelle work?
As the female body enters the menopausal and postmenopausal life stages, it begins producing less estrogen. This is a natural, universal transition.
However, reduced levels of estrogen can lead to unpleasant symptoms in some women (i.e., heart palpitations, mood changes, hot flashes, etc.).
Activelle works by providing estradiol to the body (virtually identical to the naturally produced hormone estrogen). This reduces the severity of certain vasomotor menopause/postmenopause symptoms (i.e., hot flashes, night sweats, excessive sweating, etc.).
The progestin hormone that is also in an Activelle dosage works in combination with the estradiol to help prevent endometrial hyperplasia (overgrowth of the lining of the uterus), as well as cancer of the lining of the uterus (endometrial carcinoma), if left untreated.
What is Activelle used to treat?
Activelle is used to treat women that have intact uteri, who are experiencing moderate to severe vasomotor symptoms associated with menopause and postmenopause, or vulvar or vaginal atrophy associated with menopause.
These symptoms relate specifically to temperature regulation within the body, leading to things like hot flashes, night sweats, feeling uncomfortably hot, or excessive sweating.
Because Activelle also contains the progestin hormone, it also helps reduce the chances of endometrial hyperplasia (overgrowth of the lining of the uterus) occurring.
How do you take Activelle?
Activelle tablets are to be taken orally, once a day. It can be taken with or without food.
It’s a good idea to try and take your Activelle doses around the same time each day, so that the medication maintains the highest possible level of efficacy throughout your treatment cycle.
There are 28 pills in each Activelle dial pack, and you should follow the instructions closely on the package, so that you can use the pack to help track your Activelle doses (and avoid missing any).

MHT is the most effective treatment for menopausal symptoms and has been shown to prevent bone loss.
In menopausal women who start appropriately-dosed MHT prior to age 60 OR within 10 years of their last period, the health benefits outweigh the risks.
Risks of MHT are considered very rare (~1 case per 1000 to 10,000 women on MHT per year) and may include:
- risks of stroke or blood clots in legs or lungs with oral estrogen (much lower risk with estrogen gel or patch)
- risks of dementia in women older than 65 years,
- risk of breast cancer (less than ~1 case per 1000 women on MHT per year)
These conditions are all rare, but they highlight the importance of having a full discussion with your healthcare practitioner; especially if you’re experiencing moderate to severe side effects.
Individualization is key, and your MHT treatment plan should be reassessed (at least) once a year to monitor your health, as well as ensure that you are on the correct dosage and formulation. Your practitioner can help you find balance between treating your symptoms safely, and avoiding increased risks.
