Cardura XL is a brand name for the medication doxazosin mesylate in an extended-release form, which belongs to a class of drugs known as alpha-1 adrenergic blockers. It is primarily used in the treatment of high blood pressure (hypertension) and the symptoms of benign prostatic hyperplasia (BPH), which is an enlarged prostate. By blocking alpha-1 receptors on blood vessels and in the prostate, Cardura XL causes relaxation of the blood vessels and muscles in the prostate and bladder neck, leading to improved urine flow and reduced blood pressure. The extended-release formulation allows for once-daily dosing, providing a convenient treatment option with a steady release of medication over time to manage symptoms effectively.
When using CARDURA XL, it's crucial to adhere to your doctor's instructions and thoroughly read the label that comes with the medication. This medicine can cause dizziness, lightheadedness, or fainting, especially after the first dose or when increasing the dose. Therefore, it's advisable to exercise caution when driving or operating heavy machinery until you know how CARDURA XL affects you. Common side effects include headache, tiredness, dizziness, and nausea. Although rare, more serious side effects such as irregular heartbeat, shortness of breath, or swelling of the feet, ankles, or legs can occur. It's essential to report any unusual symptoms to your doctor immediately. Additionally, inform your doctor about all other medications you are taking, as CARDURA XL can interact with other drugs, potentially leading to adverse effects. Following these precautions will help ensure the safe and effective use of CARDURA XL.
