1. What Doxazosin Tablets are and what they are used for
The active ingredient in your tablets, doxazosin belongs to a group of medicines know as alpha-1 antagonists. Doxazosin is used to treat the following conditions:
- High blood pressure. If left uncontrolled, high blood pressure can increase the risk of heart disease or stroke.
Doxazosin works by widening your blood vesssels making it easier for your heart to pump blood through them. This helps to lower raised blood pressure and reduce the risk of heart disease.
2. Before you take Doxazosin Tablets Do not take Doxazosin Tablets
- if you have ever suffered an allergic reaction to the active ingredient, doxazosin, or any of the other ingredients listed at the end of the leaflet. Allergic reactions may be, for example, itching, reddening of the skin or difficulty breathing.
- if you know that you are sensitive to quinazolines (e.g. prazosin, terazosin). Quinazolines is the chemical family of medicines to which doxazosin belongs.
- if you are breast-feeding
- if you have any form of obstruction of the digestive tract.
- if you have a history of blood pressure dropping on standing
- if you suffer from enlarged prostate gland
- if you have a problem with your bladder or passing urine
- if you are under 16 years of age.
Take special care with Doxazosin Tablets
- if you have liver problems
- if you have a heart condition
- if you have a disorder of the blood vessels of the brain
- if you have a tendency to fainting or dizziness (hypotension)
- if you suffer from accumulation of fluid on the lungs.
Before surgery and anaesthesia (even at the dentist), you should tell the doctor or dentist that you are taking Doxazosin Tablets.
If you are undergoing eye surgery because of cataract (cloudiness of the lens) please inform your eye specialist before the operation that you are using or have previously used Doxazosin Tablets. This is because Doxazosin Tablets may cause complications during the surgery which can be managed if your specialist is prepared in advance.
Taking other medicines
Tell your doctor if you are already taking any of the following:
-Non-steroidal anti-inflammatory drugs (NSAIDs), e.g. ibuprofen
- Other medicines used in the treatment of high blood pressure, e.g. ramipril, bisoprolol, nifedipine, tamsulosin
- Oestrogens (female hormones)
- Dopamine, ephedrine, adrenaline, metaraminol, methoxamine, phenylephrine (medicines used for the treatment of heart problems)
- Drugs called monoamine oxidase inhibitors (MAOI’s) used to treat depression
- Drugs used for the treatment of erection problems (PDE-5 inhibitors, e.g. sildenafil (viagra), tadalafil, vardenafil).
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 erection problems (impotence) with alpha-blockers such as Doxazosin. In order to reduce the likelihood of these symptoms occurring, you should be on a regular daily dose of your alpha-blocker before you start drugs for erection problems.
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
Taking Doxazosin with food and drink
Doxazosin can be taken with or after food.
Pregnancy and breast-feeding
Do not take Doxazosin if you are pregnant, trying to become pregnant or if you are breast-feeding. Speak to your doctor first.
Driving and using machines
Doxazosin may influence your ability to drive and use machines. If you feel dizzy or light-headed, you must not drive or operate machinery. Be especially careful when you take your first dose or if your dose is increased. Also be careful if you are starting to take your medicine again after not having taken it for some time.

You must keep taking your Doxazosin Tablets exactly as your doctor has told you. The directions should be given on the label. You should check with your doctor or pharmacist if you are not sure.
Adults and the elderly

If you take more Doxazosin Tablets than you should
If you take too many tablets you should lie down on your back with your feet higher than your head. The most likely symptoms of overdose would be a feeling of light-headedness or dizziness due to a fall in blood pressure. If you have any of these symptoms you should tell your doctor or pharmacist or go to your accident and emergency department immediately
If you forget to take Doxazosin Tablets
If you miss a dose, do not worry. Simply take the next day’s tablet when it is due. Do not take a double dose to make up for a forgotten tablet.
