Cenforce 200 mg contains sildenafil 200 mg, which is a higher-than-usual dose used for erectile dysfunction (ED). Realistic expectations are important because a higher dose does not always mean a better erection and may increase side effects. Realistic expectations  Better erection firmness for many men with ED Effect typically lasts several hours (the drug may remain active in the body longer, but this does not mean you will have a continuous erection)  It helps with physical erection response, not ***** desire, attraction, or relationship issues What it will not do   It will not create an erection without ***** stimulation   It does not increase testosterone or cure the underlying causes of ED   It does not guarantee a successful ***** experience every time About the 200 mg dose A 200 mg sildenafil dose is above the commonly recommended maximum dose (100 mg) for many patients. Higher doses can raise the risk of side effects such as: headache flushing dizziness low blood pressure indigestion nasal congestion vision changes prolonged erection (priapism), which requires urgent medical attention if it lasts more than 4 hours Avoid sildenafil if you use nitrate heart medicines (such as nitroglycerin) or have been advised to avoid ***** activity due to heart problems. If you are considering Cenforce 200 mg because 100 mg was not effective, it helps to know why it failed (timing, food, dose, anxiety, health conditions, or other medicines). I can help you troubleshoot that safely.
