Cardura XL is a medication containing doxazosin mesylate, which is used for the treatment of hypertension (high blood pressure) and benign prostatic hyperplasia (BPH) in men.

Cardura XL is an extended-release tablet designed for oral use. Doxazosin works by relaxing the muscles in the prostate and bladder neck, making it easier to urinate.

Note that Cardura XL is intended only for residents of the United States and should be used only as directed by a healthcare professional.

Use and Dosage

Read the Patient Information Leaflet if available from your pharmacist before you start taking doxazosin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually once daily with breakfast.

Doxazosin may cause a sudden drop in your blood pressure, which could lead to dizziness or fainting, usually within a few hours after you take it. This risk is higher when you first start taking this drug after your doctor increases your dose, or if you restart treatment after you stop taking it. During these times, avoid situations where you may be injured if you faint.

Swallow the tablets whole. Do not crush or chew the tablets. Doing so can release all of the drugs at once, increasing the risk of side effects.

The dosage is based on your medical condition and response to treatment.

Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. If you miss taking doxazosin for a few days, you may need to restart treatment at a lower dose and gradually increase your dose again. Consult your doctor for more details.

If you are switching from another form of doxazosin to this extended-release form, be sure to follow your doctor’s instructions closely.

Side Effects

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Serious side effects include:

  • A light-headed feeling, like you might pass out
  • Severe ongoing stomach pain or bloating
  • New or worsening chest pain
  • Trouble breathing
  • A penis erection that is painful or lasts 4 hours or longer

Common side effects of Cardura XL may include:

  • Low blood pressure or dizziness
  • Drowsiness

This is not a complete list of side effects and others may occur.


Before taking doxazosin, tell your doctor or pharmacist if you are allergic to it; or to other alpha-blockers such as prazosin or terazosin; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of: stomach/intestine problems (such as short bowel syndrome, chronic constipation, narrow gut, slow gut movement), heart disease (such as congestive heart failure, angina, heart attack in last 6 months), liver disease, low blood pressure, certain eye problems (cataracts, glaucoma).

This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).

Before having surgery (including cataract/glaucoma eye surgery), tell your doctor or dentist if you are taking or have ever taken this medication, and about all the other products you use (including prescription drugs, nonprescription drugs, and herbal products).

Older adults may be more sensitive to the side effects of this drug, especially dizziness and low blood pressure when getting up from a sitting or lying position. These side effects can increase the risk of falling.
