Cardura XL 4mg (Doxazosin) for BPH and Hypertension in Nigeria
Cardura XL 4mg is an extended-release (XL) medication containing Doxazosin mesylate. It belongs to the class of drugs known as alpha-1 adrenergic antagonists, or alpha-blockers. In Nigeria, doctors commonly prescribe Cardura XL to manage symptoms of an enlarged prostate, known as Benign Prostatic Hyperplasia (BPH), and to treat high blood pressure (hypertension).
How Cardura XL 4mg Works
Cardura XL uses advanced Gastrointestinal Therapeutic System (GITS) technology. This delivery system ensures that the Doxazosin is released slowly and steadily into your body over a 24-hour period.
For hypertension, it works by relaxing the walls of your blood vessels, making it easier for blood to flow and reducing your overall blood pressure. For BPH, it relaxes the smooth muscles in the prostate and bladder neck, which helps to improve urine flow and reduce symptoms like frequent urination or difficulty starting.
Key Benefits
- Effective BPH Relief: Helps men with enlarged prostates pass urine more easily.
- Steady Blood Pressure Control: The XL formulation provides consistent management of hypertension throughout the day and night.
- Controlled Release: The GITS technology reduces the risk of "first-dose effect" or sudden drops in blood pressure compared to immediate-release tablets.
Usage and Dosage
Cardura XL 4mg is a Prescription Only Medicine (POM). It is usually taken once daily. The tablets must be swallowed whole with water—do not crush, chew, or break them, as this will destroy the extended-release mechanism. You can take it with or without food.
If you have questions about your dosage or how this medicine affects you, contact a GoMed pharmacist for professional guidance.
Side Effects and Precautions
Common side effects may include dizziness, headache, or a feeling of tiredness. Because Cardura XL can cause your blood pressure to drop when you first start taking it, it is often recommended to take your first dose at bedtime. Always inform your doctor if you are taking other medications for blood pressure or erectile dysfunction (like sildenafil).
