Malegra 120 mg (Sildenafil citrate, high dose) is a potent dose, so medical history really matters. Here’s a detailed breakdown of conditions that require caution or may even contraindicate its use: 1. Heart and Circulatory Conditions Heart attack, stroke, or life-threatening arrhythmias within the last 6 months. Severe angina (chest pain) or uncontrolled hypertension/hypotension. Heart failure or structural heart problems. Reason: Sildenafil dilates blood vessels, lowering blood pressure, which can be dangerous in these conditions. 2. Nitrate Medication Use Any nitrate drugs for angina or chest pain (e.g., nitroglycerin, isosorbide mononitrate). Reason: Combination can cause a dangerous drop in blood pressure leading to fainting, heart attack, or stroke. 3. Liver or Kidney Disease Severe liver impairment can increase drug levels → higher risk of side effects. Severe kidney disease can slow clearance → accumulation and prolonged effect. 4. Eye Disorders Retinitis pigmentosa (rare genetic retinal disorder). History of non-arteritic anterior ischemic optic neuropathy (NAION). Reason: Sildenafil can rarely affect vision or blood flow to the optic nerve. 5. Anatomical Penile Disorders Peyronie’s disease (penile curvature). Severe deformities of the *****. Reason: Risk of painful or prolonged erections. 6. Blood Disorders Sickle cell anemia, leukemia, or multiple myeloma. Reason: Higher risk of priapism (prolonged erection), which can be a medical emergency. 7. Other Caution Situations History of stroke or bleeding disorders. Concurrent use of strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir) → can increase sildenafil levels dangerously. Allergies to sildenafil or excipients in Malegra jelly.
