Cardura (doxazosin) Tablets 4 mg. #30
Cardura is a medication that contains the active ingredient doxazosin, which belongs to a class of drugs known as alpha-blockers. It is commonly prescribed to treat high blood pressure (hypertension) and symptoms of benign prostatic hyperplasia (BPH).
What is Cardura used for?
Cardura is primarily used to treat high blood pressure by relaxing the blood vessels, allowing blood to flow more easily. This helps lower blood pressure and reduce the risk of complications such as heart attacks, strokes, and kidney problems.
In addition to treating high blood pressure, Cardura is also prescribed to manage the symptoms of benign prostatic hyperplasia (BPH). BPH is a non-cancerous enlargement of the prostate gland that can cause urinary symptoms such as difficulty urinating, frequent urination, and a weak urine stream. Cardura helps relax the muscles in the prostate and bladder, making it easier to urinate.
How does Cardura work?
Cardura works by blocking alpha-adrenergic receptors in the body. These receptors are found in the smooth muscle of blood vessels and the prostate gland. By blocking these receptors, Cardura causes the muscles to relax, which leads to vasodilation (widening of blood vessels) and improved blood flow.
By relaxing the blood vessels, Cardura helps lower blood pressure and reduce the workload on the heart. In the case of BPH, Cardura helps relax the muscles in the prostate and bladder, relieving urinary symptoms and improving urine flow.
How to take Cardura?
Cardura tablets are usually taken by mouth once daily, with or without food. The typical starting dose for high blood pressure is 1 mg. once daily, which may be increased by your doctor as needed. For BPH, the starting dose is usually 1 mg. once daily, with a maximum dose of 8 mg. per day.
It is important to take Cardura exactly as prescribed by your doctor. Do not stop taking the medication suddenly without consulting your doctor, as this can lead to a rapid increase in blood pressure or worsening of BPH symptoms. If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule.
