The active ingredient in its tablets, doxazosina, belongs to a group of medications known as alpha antagonists.

It is used to treat high blood pressure or the symptoms of Benign Prostatic Hyperplasia (BPH), which is caused by the enlargement of the prostate in men.

Your doctor may have prescribed doxazosina because your blood pressure is high (hypertension), which, if left uncontrolled, can increase the risk of cardiovascular disease or stroke. Doxazosina works by relaxing blood vessels, causing them to dilate and helping your heart pump blood through them more easily. This contributes to reducing your blood pressure and the risk of cardiovascular disease or stroke.

You may have been prescribed doxazosina to treat Benign Prostatic Hyperplasia (BPH) syndrome that causes prostate enlargement, which is located just below the bladder. The symptoms are poor and/or frequent urination. Doxazosina acts by relaxing the muscle that surrounds the bladder outlet, allowing urine to pass more easily.

Do not take Doxazosina Neo Vir

- If you are allergic (hypersensitive) to doxazosina or to any of the other ingredients of this medicine or to any quinazoline (e.g. prazosina, terazosina) (see section 6).

- If you have had low blood pressure when standing up

- If you have Benign Prostatic Hyperplasia (BPH) and have constant infections in the urinary tract or bladder stones

- If you have or have had intestinal obstruction

- If you are taking this product to treat symptoms of Benign Prostatic Hyperplasia and have low blood pressure

Do not take doxazosina as the only therapy if you have a severe kidney disorder (anuria or progressive renal insufficiency) or suffer from loss of bladder control (urinary incontinence).

Warnings and precautions

Particularly at the beginning 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 the dizziness or weakness that occurs during the start of therapy with doxazosina.

Consult your doctor or pharmacist before starting to take doxazosina:

• if you have an acute heart condition, such as heart failure.
• if you have liver disease. Since there is no experience in patients with severe liver disease, use in these patients is not recommended.

• if you are a man and use medications to treat erectile dysfunction such as sildenafilo, tadalafilo, and vardenafilo, as taking these medications at the same time as doxazosina may cause a drop in blood pressure. Your doctor will advise you on the necessary interval between taking these medications and doxazosina.

if you are to undergo eye surgery for cataracts (cloudy lens), inform your eye specialist before the operation that you are using or have used doxazosina previously. This is because doxazosina may cause complications (Intraoperative Iris Flaccidity Syndrome) during the surgical intervention that can be treated if your specialist is prepared in advance.

Before starting treatment with doxazosina, your doctor may perform tests to rule out other diseases, such as prostate cancer, which may cause the same symptoms as benign prostatic hyperplasia.

Children and Adolescents

Doxazosina is not recommended for use in children or adolescents under 18 years of age as its efficacy and safety have not been established in this population.

Use of Doxazosina Neo Vir with other medications

Some patients taking alpha-blockers for the treatment of high blood pressure or prostate enlargement may experience dizziness or vertigo, caused by a drop in blood pressure when sitting or standing up quickly. Certain patients have experienced these symptoms when taking medications with alpha-blockers for erectile dysfunction (impotence). In order to reduce the likelihood of these symptoms occurring, you should have your daily dose of alpha-blocker regulated before starting to take medications for erectile dysfunction.

If you take doxazosina with medications used to lower blood pressure (alpha-blockers and other antihypertensives), doxazosina may increase its effect.

It is especially important that your doctor knows if you are already being treated with the following medications:

- Medications used to treat bacterial or fungal infections, for example, claritromicina, itraconazol, ketoconazol, telitromicina, voriconazol.

- Medications used in the treatment of HIV, for example, indinavir, nelfinavir, ritonavir, saquinavir.

- Nefazodona, a medication used to treat depression.

Inform your doctor or pharmacist if you are using or have used recently or may need to use any other medication, including those acquired without a prescription.
