Contents of the pack and additional information

Your doctor has prescribed Doxazosina Neo ratiopharm because your blood pressure is high, which, without treatment, increases the risk of heart disease or stroke. The active ingredient in your tablets, doxazosina, belongs to a group of medicines known as alpha blockers. These drugs work by dilating blood vessels, making it easier for the heart to pump blood through them. In this way, it is easier to reduce high blood pressure.

You may also have been prescribed Doxazosina Neo ratiopharm because you have an enlarged prostate (prostatic hyperplasia), which makes it difficult to urinate. The prostate is located immediately below the bladder in men. Doxazosina Neo ratiopharm works by relaxing the muscle that surrounds the exit of the bladder and the prostate, making it easier to urinate.

Do not take Doxazosina Neo ratiopharm

• if you are allergic to doxazosina or any of the other components of this medication (listed in section 6),
• if you know you are sensitive to quinazolines (such as prazosina or terazosina), which is the chemical family to which doxazosina belongs
• if you have a history of orthostatic hypotension. Orthostatic hypotension is a drop in blood pressure that can occur when you stand up quickly from sitting or lying down, a situation that may be accompanied by dizziness
• if, in addition to benign prostatic hyperplasia, you have an infection or obstruction of the urinary tract or bladder stones
• if you suffer from or have suffered from any type of obstruction of the digestive system (only for patients taking the prolonged-release tablets)
• if, in addition to benign prostatic hyperplasia, your blood pressure is too low
• if you suffer from continuous urine loss (urinary incontinence), do not produce enough urine (anuria), or suffer from kidney insufficiency (only for patients with benign prostatic hyperplasia taking doxazosina as monotherapy)

Warnings and precautions

Consult your doctor or pharmacist before starting to take Doxazosina Neo ratiopharm

• if you have liver problems
• if you suffer from acute heart disease, such as pulmonary edema or heart failure
• if you are taking any medication to treat erectile dysfunction (see also the section “Other medications and Doxazosina Neo ratiopharm”)

At the beginning of treatment, avoid situations where injuries may occur due to dizziness or weakness, and in rare cases, fainting.

If you are to undergo eye surgery for cataracts (opacity of the crystalline lens), please inform your ophthalmologist before the operation that you are using or have used Doxazosina Neo ratiopharm previously. This is because Doxazosina Neo ratiopharm may cause complications during surgery that can be controlled if your ophthalmologist is previously notified.

The active substance in Doxazosina Neo ratiopharm is surrounded by an inert material, a non-absorbent coating designed to control the release of the substance over a prolonged period. After passing through the gastrointestinal tract, the coating of the empty tablet is separated. Do not worry if you occasionally see something in your stool that resembles a tablet.

Before starting treatment with Doxazosina Neo ratiopharm, 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

Doxazosina Neo ratiopharm is not recommended for children or adolescents under 18 years old as its safety and efficacy have not been established.

Other medications and Doxazosina Neo ratiopharm

Always discuss the medications you are taking with your doctor. This includes any medication you have purchased yourself and also any medication prescribed by a doctor. Some medications interact with Doxazosina Neo ratiopharm. These include:

• other medications used to treat high blood pressure
• medications used to treat erectile dysfunction (e.g. sildenafilo [Viagra], tadalafilo [Cialis], vardenafilo [Levitra]), see section “Warnings and precautions”. Some patients taking alpha-blockers to treat high blood pressure or prostate enlargement may experience dizziness or lightheadedness, which may be caused by low blood pressure when sitting or standing up quickly. Some patients have experienced these symptoms when taking erectile dysfunction medications (impotence) with alpha-blockers. In order to reduce the possibility of these symptoms occurring, you should be taking a regular daily dose of alpha-blockers before starting to take erectile dysfunction medication.
• medications used to treat bacterial or fungal infections, for example, claritromicina, itraconazol, ketoconazol, telitromicina, voriconazol.
• medications used to treat HIV, for example, indinavir, nelfinavir, ritonavir, saquinavir.
