1. What Doxazosin Sandoz is and what it is used for

Doxazosin Sandoz belongs to a group of medicines called alpha-blockers.

It is used to treat:

  • High blood pressure
  • Symptoms are caused by the enlarged prostate gland in men.

In patients taking this medicine for the treatment of high blood pressure ( hypertension ), the medicine works by relaxing the blood vessels so that the blood can pass through them more easily. This helps to lower blood pressure.

In patients with an enlarged prostate gland, this medicine is used to treat poor and/or frequent urination. This is common in patients with an enlarged prostate gland ( benign prostatic hyperplasia ). This drug works by making the muscle around the exit of the bladder and the prostate gland relax so that the urine can pass more easily.

Doxazosin contained in Doxazosin Sandoz may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.
