How does Catapres work? What will it do for me?

Clonidine belongs to the group of medications called antihypertensives or vascular stabilizers. It is used alone or in combination with thiazide diuretics (e.g., hydrochlorothiazide) to treat high blood pressure. It is usually tried when other types of blood pressure medications are ineffective or cannot be used. This medication works by widening the blood vessels, which increases blood flow and lowers blood pressure.

Clonidine can also be used to relieve menopausal hot flashes when hormone replacement therapy is not needed or not desired. For hot flashes, clonidine works by helping reduce the response of the blood vessels to stimuli that cause them to narrow and widen.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

How should I use Catapres?

For treatment of high blood pressure, the usual starting dose of clonidine is 0.1 mg twice daily, taken in the morning and at bedtime. After 2 to 4 weeks, your doctor may increase your dose gradually by 0.1 mg per day. The usual dose ranges from 0.1 mg to 0.3 mg twice daily.

The tablets should be swallowed whole with water.

Do not stop taking this medication suddenly without checking with your doctor.
