Warnings and precautions

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

• If you have liver problems: as there is no clinical experience in patients with severe hepatic impairment, its use is not recommended in these patients.
• If you have acute heart disease, such as pulmonary edema or heart failure.
• If you are taking any medication for erectile dysfunction (see "Taking Doxazosina Neo Teva with other medicines").

Especially at the start of treatment with this medicine, dizziness, weakness, and, in rare cases, fainting may occur. Therefore, caution should be exercised when starting treatment and situations that could cause injury if such symptoms occur should be avoided.

If you are going to undergo cataract surgery, inform your doctor before surgery if you are taking or have previously taken Doxazosina Neo Teva. This is because Doxazosina Neo Teva may cause complications during surgery, which can be taken into account and controlled by your ophthalmologist if informed beforehand.

Children and adolescents

Doxazosina is not recommended for children or adolescents under 18 years of age, as safety and efficacy have not yet been established.

Taking Doxazosina Neo Teva with other medicines

Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Doxazosina Neo Teva has been administered with other antihypertensives, other medications such as non-steroidal anti-inflammatory drugs, antibiotics, oral antidiabetics, gout medications, anticoagulants, digoxin, warfarin, phenytoin, and indomethacin without negative consequences. Doxazosina enhances the action of other antihypertensives in lowering blood pressure.

Doxazosina should be used with caution in patients receiving medications for erectile dysfunction (e.g., sildenafil, tadalafil, vardenafil), as symptomatic hypotension may occur in some patients.

Some patients who are receiving an alpha-blocker for the treatment of high blood pressure or prostatic hyperplasia may experience dizziness or fainting that can be caused by a decrease in blood pressure when sitting or standing up quickly. Some patients have experienced these symptoms when taking medications for erectile dysfunction (impotence) with alpha-blockers like Doxazosina Neo Teva. In order to minimize the likelihood of these symptoms, you should be receiving your daily dose of alpha-blocker regularly before starting treatment for erectile dysfunction.
