Clonidine Description
Generic Name: CLONIDINE
Pronunciation: (kloe' ni deen)
Trade Name(s): Arkamin, Catapres
Why it is prescribed: Clonidine controls high blood pressure
by relaxing the blood vessels so that blood can flow more easily
through the body. It has also been used to prevent migraine headaches.
When it is to be taken: In tablet form, this drug usually
is taken twice a day. When applied to the skin, clonidine is used
once every seven days. Follow the instructions on your prescription
label carefully. This medication controls high blood pressure
but does not cure it. Therefore, it is important that you use
it regularly. The tablets should be taken at evenly spaced intervals.
If you are to take clonidine twice a day, take one dose at bedtime
and the second dose 12 hours later.
How it should be taken: Clonidine comes in the form of
tablets and as patches that are applied to the skin. Your prescription
label tells you how much to take at each dose. Your doctor may
change your dose from time to time, especially when you first
start taking the drug, until your blood pressure is controlled.
If you are using the clonidine patches, carefully follow the instructions.
Apply the patches in the following way:
(1) Clean a relatively hairless area of unbroken skin on your
upper arm or chest with mild soap and water and dry it completely.
(2) Peel the clear plastic strip from the adhesive side of a patch.
(3) Attach the patch to your skin by placing the adhesive side
against it and pressing firmly.
(4) If the patch loosens before replacement time, place adhesive
tape over the top of it to secure it.
(5) Apply each patch to a different skin area to avoid irritation.
If the skin under the patch become irritated, remove the patch
and replace it with a new one in a different area.
(6) Fold the used patch in half with the sticky sides together
and dispose of it carefully. The patch still contains active medication
that could be harmful to children.
Special Instruction:
1. Clonidine makes some people drowsy. Do not drive a car or operate
dangerous machinery until you know how it affects you.
2. Alcohol, sleeping pills, and narcotics may increase the drowsiness
caused by the drug. Ask your doctor for advice about the safe
use of alcohol and other drugs while you take clonidine.
3. Your blood pressure should be checked regularly, and your eyes
may be examined occasionally.
4. Do not skip doses or stop taking clonidine, even if you feel
well without consulting your doctor.
5. Your doctor probably will want to decrease your dose gradually.
6. Be sure that you have enough medication on hand at all times,
especially for vacations and holidays.
7. If you forget to take a dose, take the missed dose as soon
as you remember it. However, if you remember a missed dose at
the time you are scheduled to take the next one, take only one
dose. Do not take a double dose.
Side Effects:
1. Dry mouth. Chew gum or suck or sugarless hard candies. This
problem should disappear as you continue to take clonidine.

common during the first few weeks of therapy and may go away.

or lying position. If these effects are severe or persistent,
