Sildamax 100 mg includes the active ingredient Sildenafil Citrate and is one of the most often prescribed drugs for the treatment of male sexual issues by doctors worldwide. It is available in 100 mg doses and is used to treat erectile dysfunction (ED) in males. Sildenafil helps men develop and sustain an erection by boosting blood flow to the penis in conjunction with sexual stimulation. This medication includes the active component Sildenafil Citrate 100mg, which is the same active ingredient as Viagra. The generic version is just less expensive and has been professionally evaluated for safety by doctors. To treat erectile dysfunction-ED, take this at least 30 minutes but no more than 4 hours before sexual activity (1 hour before is the most effective). Sildenafil improves blood flow to the penis, allowing you to obtain and maintain a difficult enough creation for sex. It often takes 30 to 60 minutes to start functioning and should only be taken prior to engaging in sexual activity. It does not, however, create an erection on its own. You must have some form of sexual stimulation in order for your penis to respond and give you an erection.
