Transcript
Doxazosin treatment might cause you to feel faint or dizzy, particularly when you stand up quickly, so
you should avoid situations when this might cause you to fall over or collapse. This is more likely to
happen when you are starting treatment or are increasing the dose.

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.

DOXAZOSIN
TABLETS

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.

It may still be alright for you to take Doxazosin Tablets and your doctor will be able to decide what is
suitable for you.

Doxazosin is also used to treat hypertension (high blood pressure) by relaxing blood vessels so that blood
passes through them more easily. This has the effect of helping to reduce the blood pressure.

2. BEFORE YOU TAKE DOXAZOSIN TABLETS
Do not take Doxazosin Tablets if you:
• are allergic (hypersensitive) to doxazosin, other alpha-blockers (e.g. prazosin or terazosin) or any of

• are breast-feeding and are taking Doxazosin Tablets for high blood pressure
• have low blood pressure and are taking Doxazosin Tablets for benign prostatic hyperplasia

your urinary tract; a long standing infection of the urinary tract; bladder stones

BPH is caused by the prostate gland growing too big and obstructing the flow of urine from the bladder.
This leads to some unpleasant symptoms such as weak or interrupted urine flow, a need to pass water
more frequently and/or a sudden need to pass water. Doxazosin can relax the muscle of the prostate
gland and bladder exit to help relieve these symptoms.

Pregnancy and breast-feeding
The safety of using Doxazosin Tablets during pregnancy has not been established. If you are pregnant,
likely to become pregnant or suspect you are pregnant you must tell your doctor before taking this
medicine.
