Cenforce 50 mg contains sildenafil, a medicine used to treat erectile dysfunction (ED). You should discuss it with a doctor before taking it for the first time, especially if you have other medical conditions or take regular medication. When should you talk to a doctor? Before starting: If you have heart disease, high or low blood pressure, liver or kidney problems, or a history of stroke or heart attack. If you take other medicines: Especially nitrates for chest pain, riociguat, certain blood-pressure medicines, or other ED treatments. Sildenafil must not be combined with nitrates. If it does not work: If you cannot get or maintain an erection despite using it correctly, consult your doctor rather than increasing the dose yourself. If side effects occur: Discuss persistent headaches, dizziness, indigestion, flushing, or visual changes. If you have frequent ED: Recurring erection problems can sometimes indicate diabetes, cardiovascular disease, hormonal issues, or psychological stress. When is medical help urgent? Seek emergency care if you experience: An erection lasting more than four hours. Sudden loss of vision or hearing. Chest pain, fainting, or severe difficulty breathing. If you develop chest pain after taking sildenafil, seek emergency help and tell the medical team when you took it. Do not take nitrates.
