Overview
Hytrin is a blood pressure medicine that relaxes the muscles lining the
blood vessels. This reduces their resistance to blood flow.
This same
action, of smooth muscle relaxation, is often helpful in managing the urinary
difficulties that may result from an enlarged prostate gland (benign prostatic
hypertrophy).
Side Effects and Interactions
The most common side effects of Hytrin are
lightheadedness or dizziness when standing up from sitting or lying down.
Even after you have been taking Hytrin for some time, this effect is
more likely within the first few hours after swallowing the pill.
Palpitations and occasionally fainting may also occur.
Other
side effects include a feeling of tiredness or weakness, headaches, nausea,
fluid build-up in arms and legs, weight gain, drowsiness, nasal stuffiness, and
blurred vision. Tell your doctor about any symptoms you experience.
Few
interactions have been reported between Hytrin and other drugs.
If other
blood pressure drugs must be added, keep in mind that the first-dose effect may
crop up and exercise precautions against fainting and falling.
Special Precautions
Hytrin can cause a potentially dangerous "first-dose effect" soon after you begin taking it.
A person may feel faint or dizzy, especially when they stand up from sitting or lying down. This is apparently due to excessive lowering of the blood pressure at first.
Your doctor will probably start you on a low dose of Hytrin and gradually increase it to reduce this problem.
Remember that if you miss a few doses, starting again could produce this first-dose effect.
Avoid driving and other dangerous activities for at least 12 hours after your first pill or after resuming medication.
Don't stand up suddenly without holding on to something.
Taking the Medicine
Hytrin is started as a 1 mg pill given at bedtime.
The dose will be increased gradually
until the response is satisfactory.
Your doctor will tell you if you should take it once
or twice a day.
