Colixil XL 4 mg Prolonged-release Tablets are one of a group of medicines called alpha-blockers.
They are 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.
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 Colixil 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 Colixil XL 4 mg Prolonged-release Tablets 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

Colixil XL 4 mg Prolonged-release Tablet is a prolonged release tablet. The medicine is contained within a non-absorbable shell that has been specially designed to slowly release the medicine. Once swallowed, doxazosin is slowly released into the body from the tablet, until the tablet is empty.
