Suhagra 50 mg contains sildenafil, taking more than recommended doesn't necessarily produce a better or longer erection—it increases the risk of side effects. For most adults, 50 mg is the usual starting dose, and the recommended maximum is 100 mg once in 24 hours. D DailyMed +1 Overdosing can increase the likelihood or severity of: Severe headache, flushing and dizziness Low blood pressure, fainting, or rapid heartbeat Vision disturbances Nausea/indigestion A prolonged, painful erection lasting more than 4 hours (priapism), which is an emergency. D DailyMed Especially important: sildenafil must not be combined with nitrate medicines such as nitroglycerin or isosorbide, because the combination can cause a dangerous drop in blood pressure. D DailyMed Also, don't combine Suhagra with Tadacip/Tadarise (tadalafil) unless a doctor specifically directs you to do so. If you tell me how many mg you were thinking of taking (e.g., 100 mg or 150 mg) and whether you take any heart/BP medicines, I can explain the specific risk.
