Table of contents:

Cardura XL is a prescription medication that contains the active ingredient doxazosin mesylate. It belongs to a group of drugs called alpha-blockers and is primarily used to treat the symptoms of benign prostatic hyperplasia (BPH), a condition in which the prostate gland becomes enlarged and makes it difficult to urinate. Cardura XL works by relaxing the muscles in the prostate and bladder neck, which helps to relieve the symptoms of BPH.

In addition to its use in treating BPH, doxazosin is also indicated for the treatment of hypertension, or high blood pressure. It is usually taken once daily with breakfast and may take several weeks to reach its full effect.

Use and Dosage

Cardura XL (Doxazosin) is an oral tablet that is taken as directed by a doctor, usually once daily with breakfast. Swallow the tablets whole and not chew or crush them, as doing so can release all the drug at once and increase the risk of side effects.

The recommended dosage of Cardura XL (Doxazosin) depends on the individual's medical condition and response to treatment. However, the usual initial recommended dose is 4mg once daily. Depending on the patient's symptomatic response and tolerability, the dose may be increased to a maximum of 8mg once daily. Consult with your doctor for specific dosage instructions based on your individual needs.

To get the most benefit from it, take Cardura XL regularly at the same time each day. If you miss taking the medication for a few days, you may need to restart treatment at a lower dose and gradually increase it again. It is important to consult your doctor for more details.
