Get Cardura Online

Cardura is FDA-approved to treat the urinary symptoms of benign prostatic hyperplasia (BPH), such as weak stream, frequent urination, and difficulty starting urination. It is also approved to treat high blood pressure (hypertension) in adults.

Doxazosin blocks alpha-1 adrenergic receptors found in the smooth muscle of the prostate, bladder neck, and blood vessel walls. Blocking these receptors allows the muscles to relax, improving urine flow for BPH patients and reducing resistance in blood vessels to lower blood pressure.

Common side effects include dizziness, headache, fatigue, and low blood pressure upon standing (orthostatic hypotension). The risk of dizziness and fainting is highest after the first dose or when the dose is increased, so doxazosin is typically started at a low dose and titrated gradually.

Many patients notice an improvement in urinary symptoms within one to two weeks of starting treatment. Blood pressure reduction can occur within a few hours of the first dose. Full benefit at a given dose is usually apparent after two to four weeks.

No. Cardura relaxes the smooth muscle around the prostate and bladder neck but does not reduce prostate size. Medications that reduce prostate volume, such as 5-alpha reductase inhibitors, work through a different mechanism and are sometimes used alongside alpha-blockers.

Yes. Doxazosin is approved for both BPH and hypertension and can address both conditions simultaneously. However, combining it with other blood pressure medications may cause an additive blood pressure-lowering effect, so your physician will review all your current medications before prescribing.
