This post is also available in:

Medication Name: Cardura 1 mg tablets
Active Ingredient: Doxazosin mesylate 1 mg
Drug Class: Alpha-1 adrenergic blocker

Indications:

Cardura is used for:

1. Hypertension (high blood pressure) – helps relax blood vessels so blood can flow more easily.

2. Benign prostatic hyperplasia (BPH) – relieves urinary symptoms caused by an enlarged prostate such as:

   • Difficulty starting urination

   • Weak stream

   • Frequent or urgent urination (especially at night)

Mechanism of Action:

Doxazosin blocks alpha-1 receptors in the vascular smooth muscle and prostate, leading to:

• Vasodilation, lowering blood pressure.

• Relaxation of the prostate and bladder neck muscles, improving urine flow in BPH.

Dosage and Administration:

• Initial dose: 1 mg once daily, usually taken at bedtime to reduce the risk of dizziness or fainting (first-dose effect).

• The dose may be gradually increased by the physician based on response, typically up to 4–8 mg once daily.

• Can be taken with or without food.

• Take the tablet at the same time each day.

Side Effects:

• Dizziness or lightheadedness (especially after the first dose)

• Fatigue or drowsiness

• Headache

• Swelling of legs or feet (edema)

• Nasal congestion

• Palpitations or low blood pressure

Warnings and Precautions:

• Use caution when standing up from sitting or lying down (may cause sudden drop in blood pressure).

• Avoid driving or operating machinery until you know how it affects you.

• Inform your doctor if you have:

  • Liver disease

  • Heart problems

  • Low blood pressure or history of fainting

• If used for BPH, treatment may be combined with other prostate medications such as finasteride if needed.

Storage:

Store below 25°C, away from moisture and direct sunlight.
