Patient leaflet - Doxand XL 4 mg prolonged-release tablets

1. WHAT DOXAND XL 4 MG PROLONGED-RELEASE TABLETS IS AND WHAT IT IS USED FOR

Doxand XL 4 mg Prolongued release tablets is one of a group of medicines called alpha-blockers.

It is used to treat:

  • high blood pressure
  • symptoms caused by enlargement of the prostate gland in men.

In patients taking this medicine to treat high blood pressure (hypertension), it works by relaxing blood vessels so that blood passes through them more easily. This helps to lower blood pressure.

In patients with enlargement of the prostate gland, this medicine is taken to treat poor and/or frequent passing of urine. This is common in patients with enlargement of the prostate gland (benign prostatic hyperplasia). This medicine works by relaxing muscle around the bladder exit and prostate gland so urine is passed more easily.

2. What you need to know before you take Doxand XL 4 mg Prolonged-release Tablets

Do not take this medicine

  • if you are allergic (hypersensitive) to doxazosin, related quinazolines e.g. prazosin or terazosin, or any of the other ingredients of this medicine (see section 6).
  • if you have had any form of obstruction of the digestive tract
  • if you have an enlarged prostate gland together with congestion of the upper urinary tract, chronic urinary tract infections or bladder stones
  • if you suffer from a loss of bladder control (bladder overflow), an inability to urinate, or kidney failure
  • if you are breast-feeding
  • if you are being treated for an enlarged prostate gland and you have low blood pressure
  • if you have or have ever had a fall in blood pressure on standing up, causing dizziness, light-headedness or fainting

Warnings and precautions

Talk to your doctor before taking this medicine:

  • if you have liver disease
  • if you have heart disease
  • if you undergo a surgery of cataract (clouding of eye lens)
  • If you are pregnant or trying to become pregnant
  • If you are also taking other medicines

Dizziness, weakness and in rare cases fainting may occur, especially when you first start taking this medicine. You should therefore be careful at the beginning of treatment, and avoid situations that could lead to injury if these symptoms occur.

Other medicines and Doxand XL 4 mg Prolonged-release tablets

Please tell your doctor or pharmacist if you are taking or have recently taken or might take any other medicines, including medicines obtained without a prescription. It is especially important to mention the following before taking this medicine:

  • medicines used to treat difficulties in getting an erection (e.g sildenafil, tadalafil or vardenafil); together with Doxand XL they may lower your blood pressure
  • medicines for high blood pressure (called anti-hypertensives)

Some patients who take alpha-blocker therapy for the treatment of high blood pressure or prostate enlargement may experience dizziness or light-headedness, which may be caused by low blood pressure upon sitting or standing up quickly. Certain patients have experienced these symptoms when taking drugs for erectile dysfunction (impotence) with alpha-blockers. In order to reduce the likelihood that these symptoms occur, you should be on a regular daily dose of your alpha-blocker before you start drugs for erectile dysfunction.

Pregnancy and breast-feeding

  • If you are pregnant do not take this medicine without consulting your doctor first. The safety of this medicine in pregnancy is not sufficiently established.
  • You should not take this medicine if you are breast-feeding (see section 2 `Do not take this medicine`).

Driving and using machines

Take care if you drive or operate machinery. Your tablets may affect your ability to drive or operate machinery safely, particularly when you first start to take them. They may make you feel weak or dizzy. If affected, do not drive or operate machinery and contact your doctor immediately.
