Product Details

Description

Buy Cardura Online from Licensed Canadian Pharmacies

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.

Uses and Benefits

What Is Cardura Used For?

Cardura is used to treat:

  • High blood pressure (hypertension)
  • Benign prostatic hyperplasia or BPH

What Are the Benefits of Cardura?

  • Cardura helps reduce nighttime urination caused by BPH.
  • Since it targets muscle tension rather than shrinking the prostate, Cardura for BPH often starts helping within just a few days.
  • Many men notice less hesitancy, stronger urine flow, and less straining when urinating.
  • Cardura can be added to other blood pressure medicines if extra control is needed.
  • This medicine may reduce urinary retention and the need for catheters in men with severe blockage.
Dosage

What Is the Recommended Dosage of Cardura?

Dosage of Cardura for Benign Enlargement of the Prostate

For adults:

  • Starting dose: Take 1 mg once per day.
  • Dose adjustment: Your health care provider will increase your dose to up to 8 mg once daily, gradually.
Dosage of Cardura for High Blood Pressure

For adults:

  • Starting dose: Take 1 mg once per day.
  • Dose adjustment: Your provider can increase your dose up to 16 mg once daily, if needed.

For children: Dose and use for children will be decided by a health care professional.

Usage Guide

How Do You Take Cardura Tablets?

Follow these steps when you buy Cardura from Canada and start taking it:

  • Take your dose at the same time every day, either in the morning or in the evening.
  • Swallow the tablets whole with water.
  • Slowly stand up from a sitting or lying position to avoid dizziness.
How It Works

How Does Cardura Work?

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).

Side Effects

What Are the Side Effects of Cardura?

Common Cardura side effects may include:

  • Lightheadedness (feeling dizzy, particularly when standing)
  • Headache
  • Unusual weakness or tiredness
  • Runny nose
  • Lack of energy
  • Edema (peripheral fluid retention) in some patients

Serious side effects (rare):

  • Marked orthostatic hypotension (blood pressure drop when standing) with fainting, especially after the first dose or dose escalations
  • Syncope (loss of consciousness) from sudden blood pressure drops
  • Priapism (painful, prolonged erection): This is rare, but if it happens, it requires urgent medical attention
  • Intraoperative floppy iris syndrome (IFIS) during cataract surgery, which may complicate the procedure
  • Severe allergic reactions like swelling or breathing difficulty

Note: Call your provider if you experience any serious symptoms or unusual changes.

Safety Guide

What Precautions Should You Take While Using Cardura?

To use Cardura safely, take these precautions:

  • If you feel light-headed, sit or lie down. Seek help if you feel like you’ll faint.
  • Tell all your health care providers, especially eye surgeons, if you’re currently taking or have ever taken an alpha-blocker.
  • Try not to combine Cardura tablets with medicines that lower blood pressure.
  • If taking Cardura for BPH, get your prostate checked timely and follow up with your health care provider.
Missed Dose

What Should You Do If You Miss A Dose of Cardura?

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.

Overdose

What Happens When You Take Too Much of Cardura?

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.
