Cardura is an oral alpha-1 adrenergic blocker used to ease symptoms of an enlarged prostate (BPH) and to help lower high blood pressure (BP). The first few doses can sometimes cause a sudden drop in blood pressure. Doctors typically begin with a low dose and adjust it slowly.
It contains doxazosin mesylate, which helps in relaxing tight muscles in the bladder neck and prostate, so urination becomes easier. This medicine also widens blood vessels to support healthier blood pressure levels.
Cardura is available in common strengths (1 mg, 2 mg, 4 mg, and 8mg). If you are comparing safe options or looking to buy Cardura online from Canada, obtain a prescription from your health care provider and always follow their guidance.

Follow these steps when you buy Cardura from Canada and start taking it:
Doxazosin (Cardura’s active ingredient) works by blocking certain receptors called alpha-1 receptors. In blood vessels, this action relaxes the muscle walls, which allows them to widen. This action makes blood flow easily, which lowers blood pressure.
In the urinary tract, it relaxes the muscles in the bladder neck and prostate. This helps urine pass more freely and eases symptoms of an enlarged prostate (BPH).
Common Cardura side effects may include:
Serious side effects (rare):
Note: Call your provider if you experience any serious symptoms or unusual changes.

To use Cardura safely, take these precautions:
Missing a dose of Cardura tablets is not likely to cause any severe side effects, so take it when you remember the very same day, unless it’s close to your time of daily routine dose. In that case, skip the one you missed and resume with your daily dosing regimen.
Don’t take a higher dose than your doctor has prescribed, as it may cause severe low blood pressure, dizziness, and a fast heart rate.
If you or someone accidentally took an extra dose, contact your local emergency services or the Poison Control Center 1-800-222-1222 in the U.S. right away.
