Malegra FXT Plus (commonly a combination of sildenafil + fluoxetine) has some important emergency precautions because it can affect blood pressure, heart function, vision, and serotonin levels. Seek emergency medical help immediately if you have: Chest pain, severe dizziness, fainting, or trouble breathing (especially during or after ***** activity) An erection lasting more than 4 hours (priapism) — this needs urgent treatment to prevent permanent injury Sudden vision loss or sudden hearing loss Severe allergic reaction: swelling of face/lips/tongue, hives, or difficulty breathing Symptoms of serotonin syndrome (rare but serious): agitation, confusion, fever, heavy sweating, fast heartbeat, shaking/tremor, muscle stiffness, vomiting, or diarrhea Avoid or use only with medical advice: Nitrate medicines for chest pain (such as nitroglycerin) — combining them with sildenafil can cause a dangerous drop in blood pressure. Recreational “poppers” (amyl nitrite/nitrate) — same blood-pressure risk. Other erectile dysfunction medicines unless your doctor specifically advises it. Alcohol excess, which can worsen dizziness, low blood pressure, and side effects. Other antidepressants or serotonin-increasing medicines (including MAO inhibitors, certain migraine medicines, tramadol, etc.) without medical supervision because of fluoxetine interactions. Extra caution before taking it if you have: Heart disease, recent heart attack, irregular heartbeat, stroke history Very low or uncontrolled blood pressure Severe liver disease Eye problems such as certain retinal disorders If you tell me your Malegra FXT Plus strength (for example 100/60), your age, and whether you take BP medicines, nitrates, or antidepressants, I can help identify your specific risk factors.
