Reserpine (patient information)

# Why is this medication prescribed
Reserpine is used to treat high blood pressure. It works by decreasing your heart rate and relaxing the blood vessels so that blood can flow more easily through the body. It also is used to treat severe agitation in patients with mental disorders.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

# How this medication should be used
Reserpine comes as a tablet to take by mouth. It usually is taken once daily. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take reserpine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Reserpine controls high blood pressure or symptoms of agitation, but does not cure them. Continue to take reserpine even if you feel well. Do not stop taking reserpine without talking to your doctor. Abruptly stopping reserpine may increase blood pressure and cause unwanted side effects.

# Special precautions
Before taking reserpine:
- tell your doctor and pharmacist if you are allergic to reserpine, aspirin, tartrazine (a yellow dye in some processed foods and medications), or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially amitriptyline (Elavil), clomipramine (Anafranil), desipramine (Norpramin), digoxin (Lanoxin), doxepin (Adepin, Sinequan), ephedrine, epinephrine, imipramine (Tofranil), MAO inhibitors , methylphenidate (Ritalin), nortriptyline (Aventyl, Pamelor), phenylephrine, protriptyline (Vivactil), quinidine (Quinaglute), trimipramine (Surmontil), and vitamins.
- tell your doctor if you have or have ever had kidney disease, gallstones, ulcers, ulcerative colitis, a history of depression, or electric shock therapy.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking reserpine, call your doctor.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking reserpine.
- you should know that this drug may make you drowsy or dizzy. Do not drive a car or operate machinery until you know how it affects you.
