Guanfacine hydrochloride

Pronounced: GWAHN-fah-seen

Why is Guanfacine hydrochloride prescribed?

Guanfacine is given to help control high blood pressure. This medication reduces nerve impulses to the heart and arteries; this slows the heartbeat, relaxes the blood vessels, and thus reduces blood pressure. Guanfacine may be given alone or in combination with other high blood pressure medications, especially thiazide diuretics, such as Diuril, Esidrix, or Naturetin.

Most important fact about Guanfacine hydrochloride

You must take guanfacine regularly for it to be effective. Since blood pressure declines gradually, it may be several weeks before you get the full benefit of guanfacine; and you must continue taking it even if you are feeling well. Guanfacine does not cure high blood pressure; it merely keeps it under control.

How should you take Guanfacine hydrochloride?

Take guanfacine exactly as prescribed by your doctor--usually 1 dose per day. Guanfacine should be taken at bedtime, since it will probably cause drowsiness.

After 3 or 4 weeks, if your blood pressure is still too high, your doctor may raise the dosage of guanfacine. In some cases, you may take 2 evenly spaced doses per day rather than a single dose at bedtime.

--If you miss a dose...

Take the forgotten dose as soon as you remember. This will help to keep the proper amount of medicine in your body. However, if it is almost time for the next dose, skip the one you missed and go back to your regular schedule. Never try to "catch up" by doubling the dose. If you miss taking guanfacine for 2 or more days in a row, check with your doctor.

--Storage instructions...

Store guanfacine at room temperature. Use the container it came in.

Guanfacine hydrochloride side effects

Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine whether it is safe for you to continue taking guanfacine. This medication will probably make you drowsy, especially when you first begin to take it.
