Read the entire leaflet carefully before starting to take the medicine because it contains important information for you.
even if they have the same symptoms, as it may harm them.
Contents of the leaflet
The active substance in your tablets, doxazosin, belongs to a group of medicines known as alpha-blockers.
It is used to treat high blood pressure or symptoms of Benign Prostatic Hyperplasia (BPH), which is caused by the enlargement of the prostate in men.
Your doctor may have prescribed doxazosin because your blood pressure is high (hypertension), which, if left uncontrolled, can increase the risk of heart disease or stroke. Doxazosin works by relaxing blood vessels, making them wider and helping your heart pump blood through them more easily. This helps reduce your blood pressure and the risk of heart disease or stroke.
Your doctor may have prescribed doxazosin to treat the symptoms of Benign Prostatic Hyperplasia (BPH) that cause prostate enlargement, which is located just below the bladder. The symptoms are poor and/or frequent urination. Doxazosin acts by relaxing the muscle that surrounds the bladder outlet, allowing urine to pass more easily.
Do not take Doxazosin Neo Vir
Doxazosin should not be taken as the only therapy if you have severe kidney disorder (anuria or progressive renal failure) or suffer from loss of bladder control (urinary incontinence).
Warnings and precautions
Particularly at the start of therapy, you may experience a drop in blood pressure when standing up (postural hypotension) characterized by dizziness and weakness or, rarely, loss of consciousness (syncope). Your doctor may monitor your blood pressure regularly at the start of therapy to minimize the risk of these effects. You should avoid situations that could cause harm as a result of dizziness or weakness that occurs during the start of doxazosin therapy.
Consult your doctor or pharmacist before starting to take doxazosin:
Before starting treatment with doxazosin, your doctor may perform tests to rule out other diseases, such as prostate cancer, which can cause the same symptoms as benign prostatic hyperplasia.
Children and Adolescents
Doxazosin is not recommended for use in children or adolescents under 18 years, as its efficacy and safety have not been established in this population.
Use of Doxazosin Neo Vir with other medicines
Some patients taking alpha-blockers for the treatment of high blood pressure or prostate enlargement may experience dizziness or lightheadedness, caused by a drop in blood pressure when sitting or standing up quickly. Certain patients have experienced these symptoms when taking medicines with alpha-blockers for erectile dysfunction (impotence). To reduce the likelihood of these symptoms, you should have your daily dose of alpha-blocker regulated before starting to take medicines for erectile dysfunction.
If you take doxazosin with medicines used to lower blood pressure (alpha-blockers and other antihypertensives), doxazosin may increase their effect.
