OWHAT DOXAZOSIN IS AND WHAT IT IS USED FOR
Doxazosin belongs to the group of medicines called vasodilatants (alpha-blockers).
Doxazosin is used to treat:
• high blood pressure
• the symptoms caused by an enlarged prostate gland in men.
Doxazosin works by widening the blood vessels, making it easier for the heart to pump blood around the body. This helps to lower blood pressure.
In patients with enlargement of the prostate gland, Doxazosin works by relaxing the muscles around the bladder and prostate gland so that urine may be passed more easily.
WHAT YOU NEED TO KNOW BEFORE YOU TAKE DOXAZOSIN
Do NOT take Doxazosin:
• if you are allergic (hypersensitive) to doxazosin, or to other medication from the same medicine category (the so-called quinazolines, such as prazosin or terazosin), or to any of the other ingredients of Doxazosin (listed in section 6)
• if you suffer from dizziness when standing up from a lying or sitting position due to decrease in blood pressure (orthostatic hypotension)
• if you have experienced problems with urinating and are using Doxazosin as monotherapy:
• have a loss of urinary control (overflow bladder)
• decreased or absent production of urine (anuria)
• progressive kidney insufficiency • if you are breast-feeding
Additionally, if you were prescribed doxazosin for an enlarged prostate you should not take this medication if you:
• have low blood pressure • have congestion of the upper urinary tract • suffer from chronic infections of the urinary tract • have bladder stones.
Warnings and precautions
Take special care with Doxazosin • at start of the treatment. The blood pressure reducing influence may be stronger, which is noticeable by dizziness and weakness or sometimes fainting. Your doctor may check your blood pressure to minimize the risk. Avoid situations in which you could be hurt when you experience dizziness or weakness • if you are suffering from acute heart disease • if you have liver problems. In patients with severe liver function impairment, use of Doxazosin is not recommended.
• if you are using certain medication for erectile dysfunction (PDE-5-inhibitors) such as sildenafil, tadalafil and vardenafil (see section "Taking other medicines")
• 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. This is because Doxazosin may cause complications during the surgery which can be managed if your specialist is prepared in advance.
Children
Use in children below the age of 12 years is not recommended.
If any of these apply to you, talk to your doctor before you start to take this medicine.
Other medicines and Doxazosin
Some medicines may influence each other's activity and/or side effects if taken simultaneously (known as interaction). An interaction can occur when this medication is taken at the same time with:
• other blood pressure lowering agents (antihypertensives) or other alpha-blockers (e.g. prazosin, terazosin); the blood pressure lowering effect can be increased
• medicines which may influence the metabolism of the liver such as cimetidine, a H2-receptor antagonist (which acts to decrease the natural production of acid in the stomach), medication for erectile dysfunction (PDE-5-inhibitors) such as sildenafil, 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 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.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.
These remarks can also be applicable to medicines you have taken in the recent past or you will take in the near future as well as medicines you are already taking. Medicines mentioned in this section may be known to you under another name, usually a branded name. In this section only the name of the active ingredient is mentioned and not the branded name. Look at the package or in the patient information leaflet of your other medicines to see what the active ingredient is of the medication you take.
Pregnancy, breast-feeding and fertility
• Do not take doxazosin if you are breast-feeding. See also section 'Do not take Doxazosin'.
• Alternatively, mothers should stop breast-feeding when treatment with doxazosin is necessary.
• If you are pregnant or are planning to become pregnant, talk to your doctor before taking this medicine. Doxazosin is not recommended for use during pregnancy unless your doctor decides that the potential benefit of treatment outweighs the risks.
