Cenforce D is a combination of two ingredients: Sildenafil Citrate and Dapoxetine. This is helpful in the treatment of erectile dysfunction and premature ovulation. It has 60mg of dapoxetine and 100 mg of sildenafil. Sildenafil Citrate is a vasodilator that dilates blood vessels in the male genital area, increasing blood flow. The other active ingredient, dapoxetine works by obstructing the serotonin reuptake channels, which stops serotonin from reentering the synapses. Flushing, headaches, blurred vision, indigestion, muscle discomfort, and upset stomach are a few of the primary side effects of Cenforce D. Most Cenforce D side effects are minor and will go away as your body responds to the medication.
