- USES
-
- Guanethidine is used to control high blood pressure. It works by

- pressure.
-
- TREATMENT
-
- Guanethidine can be taken either on an empty stomach or, to avoid stomach
- irritation, with food or milk (as directed by your doctor). Try to take your
- doses at the same times each day, in order to become accustomed to taking this
- medication.
- This medication does not cure high blood pressure, but it will help to
- control the condition, as long as you continue to take it.
- If you miss a dose of this medication, take the missed dose as soon as
- possible, unless it is almost time for the next dose. In that case, do not
- take the missed dose at all; just return to your regular dosing schedule. Do
- not double the next dose.
-
- SIDE EFFECTS
-
- Minor.
-
- Diarrhea; dizziness; dry mouth; fatigue; nasal congestion; nausea;
- vomiting; weakness; and weight gain. These side effects should disappear in
- several weeks, as your body adjusts to the medication.
- If you feel dizzy, sit or lie down awhile; change positions slowly, and
- be careful on stairs.
- To help relieve mouth dryness, chew sugarless gum, or suck on ice chips
- or a piece of hard candy.
-

- eyelids; hair loss; increased urination; itching; muscle pain or tremors;
- rapid weight gain (three to five pounds within a week); skin rash; shortness

-
- INTERACTIONS
-
- Guanethidine interacts with several other types of drugs.
- 1. Concurrent use of guanethidine and alcohol can lead to fainting or
- extreme drowsiness.
- 2. Amphetamines, appetite suppressants, ephedrine, methylphenidate,
- phenothiazine tranquilizers, phenylpropanolamine, and tricyclic
- anti-depressants can decrease the beneficial effects of guanethidine.
- 3. Barbiturates, methotrimeprazine, narcotics, fenfluramine, and
- reserpine can increase the blood-pressure-lowering effects of guanethidine,
- which can be dangerous.
- 4. The dosage of oral anti-diabetic medications may need to be adjusted
- when guanethidine is started.
- 5. Concurrent use of guanethidine with monoamine oxidase (MAO) inhibitors
- can lead to serious side effects. At least one week should separate doses of
- these two types of medication.
- BE SURE TO TELL YOUR DOCTOR if you are already taking any of the
- medications listed above in combination with guanethidine.
