Cenforce is a brand of sildenafil, the same active ingredient used in Viagra. Whether it’s appropriate for you depends mainly on your health conditions, medications, and what’s causing the erection problem. Cenforce may be appropriate if You have difficulty getting or maintaining an erection. You can safely engage in ***** activity. You aren't taking medicines that dangerously interact with sildenafil. You should not use it without medical advice if You take nitrates for chest pain (such as nitroglycerin or isosorbide) — this combination can cause a dangerous drop in blood pressure. You take riociguat. You have significant heart disease, very low/high blood pressure, recent heart problems or stroke, or significant kidney/liver disease. You take alpha-blockers or several blood-pressure medicines, because your dose may need adjustment. Common side effects include headache, flushing, indigestion/heartburn, nasal congestion, nausea, and visual changes. An erection lasting more than 4 hours, sudden vision/hearing loss, fainting, or chest pain requires urgent medical attention. If you want, I can help you assess whether Cenforce 50 mg or 100 mg would be reasonable based on your situation.
