Cenforce 100 mg usually starts working within 30 to 60 minutes after taking the tablet. However, the exact onset time can vary depending on factors such as your age, metabolism, overall health, and whether you have eaten a heavy meal beforehand. Taking Cenforce 100 mg on an empty stomach or after a light meal may help it work more quickly, while high-fat foods can delay its effects. The medication requires sexual stimulation to be effective and does not cause an automatic erection. Its effects typically last for 4 to 6 hours, although this does not mean you will have a continuous erection during that time. To achieve the best results, take Cenforce only as prescribed by your healthcare provider and avoid excessive alcohol consumption, as it may reduce the medication's effectiveness. Never take more than one dose within a 24-hour period without medical advice.
