Tell your prescriber or health care professional about all other medicines you are taking, including nonprescription medicines, nutritional supplements, or herbal products. Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your prescriber or health care professional before stopping or starting any of your medicines.

What side effects may I notice from taking terazosin?

Side effects that you should report to your prescriber or health care professional as soon as possible:

Rare or uncommon:

• difficulty breathing, shortness of breath
• prolonged painful erection of the penis (priapism)

More common:

• blurred vision
• fainting spells, lightheadedness
• fast or irregular heartbeat, palpitations or chest pain
• swelling of the legs and ankles

Side effects that usually do not require medical attention (report to your prescriber or health care professional if they continue or are bothersome):

• constipation or diarrhea
• drowsiness or dizziness
• headache
• nausea
• nasal stuffiness
• unusual weakness or tiredness

What should I watch for while taking terazosin?

Check your blood pressure regularly. Ask your prescriber or health care professional what your blood pressure should be and when you should contact him or her.

Do not take capsules that show evidence of melting or breakage. Terazosin capsules must be stored at a controlled room temperature (see below).

You may feel drowsy or dizzy. Do not drive, use machinery, or do anything that requires mental alertness until you know how terazosin affects you. To reduce the risk of dizzy or fainting spells, do not sit or stand up quickly. Avoid alcoholic drinks; they can make you more drowsy, increase flushing, and cause rapid heartbeats. Taking initial doses of terazosin at bedtime can lessen the effects of drowsiness and dizziness, but be careful if you have to get up during the night. Drowsiness and dizziness are more likely to occur after the first dose, after an increase in dose, or during hot weather or exercise. These effects can decrease once your body adjusts to this medicine.

Although extremely rare in men taking terazosin, contact you health care provider immediately if you experience prolonged and painful erection of the penis which is unrelated to sexual activity (priapism). If not brought to immediate medical attention, priapism can lead to permanent erectile dysfunction (impotence).

If you are going to have surgery, tell your prescriber or health care professional that you are taking terazosin.

Where can I keep my medicine?

Keep out of the reach of children in a container that small children cannot open.

Store at room temperature between 20 and 25 degrees C (68 and 77 degrees F). Higher temperatures may cause the capsules to soften or melt. Protect from light and moisture. Throw away any unused medicine after the expiration date.

What is the shelf life of the pills?

• The expiry date is mentioned on each blister. It is different for different batches. The shelf life is 2 years from the date of manufacture and would differ from batch to batch depending on when they were manufactured.
