Clonidine belongs to a group of medicines called vasodilators. Vasodilators widen the blood vessels to help the blood flow more easily. Clonidine is used for various reasons. For example to:
- reduce hot flushes and night sweats for menopausal women
- treat high blood pressure when other medicines may not work well
- treat severe pain.
Clonidine has also been used for migraine prevention but it is not generally recommended – other options are preferred. Read more about medicines to prevent migraine.
