Cenforce 150 mg if any of the following situations apply, because 150 mg is a high-dose sildenafil tablet, higher than standard doses: 1. Pre-existing health conditions Heart problems: Chest pain, angina, heart attack history, irregular heartbeat, or heart failure. Low or high blood pressure that is not well controlled. Liver or kidney disease, which can affect how the drug is metabolized. Stroke history or severe vascular problems. 2. Medication interactions You are taking nitrates (for angina) or nitric oxide donors—this combination can cause dangerous drops in blood pressure. Alpha-blockers or certain blood pressure medications may interact. Other ED medications or recreational drugs can increase side effects. 3. Side effects during or after use Severe headache, dizziness, fainting, or chest pain. Prolonged erection lasting more than 4 hours (priapism) — medical emergency. Sudden vision changes, hearing loss, or allergic reactions (rash, swelling, difficulty breathing). 4. Before first use If you have never taken sildenafil before, a doctor should assess your heart health and suitability for a 150 mg dose. Men over 65 or with chronic illnesses may need a lower starting dose. Summary: Cenforce 150 mg is strong, and while it may be effective for ED, it carries higher risk of side effects than standard doses. Consult a doctor before taking it, and seek immediate medical help if severe reactions occur.
