Important safety information:

Hytrin may cause drowsiness, dizziness, blurred vision, or lightheadedness. These effects may be worse if you take it with alcohol or certain medicines. Use Hytrin with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
Do not drink alcohol or use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Hytrin ; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
Hytrin may cause a sudden drop in blood pressure after the very first dose. Take you first dose at bedtime. If you get up during the night, sit up slowly, then stand slowly. This will help to reduce your lightheadedness or dizziness. These effects will more likely occur after you have taken the first few doses or if you have increased your dose, but can occur at any time while you are taking the medicine. It can also occur if you stop taking the medicine and restart treatment.
Hytrin may cause dizziness, lightheadedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
Patients who take medicine for high blood pressure often feel tired or run down for a few weeks after starting treatment. Be sure to take your medicine even if you may not feel "normal." Tell your doctor if you develop any new symptoms.
Hytrin may rarely cause a prolonged, painful erection. This could happen even when you are not having sex. If this is not treated right away, it could lead to permanent sexual problems such as impotence. Contact your doctor right away if this happens.
Hytrin should not be used in CHILDREN; safety and effectiveness in children have not been confirmed.
PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Hytrin while you are pregnant. It is not known if Hytrin is found in breast milk. If you are or will be breast-feeding while you use Hytrin , check with your doctor. Discuss any possible risks to your baby.
