Clonidine for Treating Hot Flashes
Clonidine is available by prescription only in pill or patch form.
How It Works
Clonidine is a blood pressure medicine that relaxes the smooth muscle of blood vessels, causing them to widen, or dilate. This reduces the pressure of blood flow through the artery. Clonidine's effect on hot flashes is not well understood.
Why It Is Used
Clonidine can be used to treat hot flashes. Because it is a nonhormonal treatment, women with a history of breast cancer can use it without increasing the risk of further cancer cell growth (as in the case of estrogen treatment).
How Well It Works
Clonidine may relieve hot flashes for some women. But studies have not shown that clonidine makes hot flashes less severe or less frequent.1
If you have high blood pressure and hot flashes, clonidine may be an effective choice for both problems.

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Advice for women
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
