Sildenafil citrate 100 mg is a medication commonly used to treat Erectile Dysfunction in men. It works by increasing blood flow during sexual stimulation, helping achieve and maintain an erection. The well-known brand version is Viagra, while generics such as cenforce 100 mg contain the same active ingredient. The 100 mg dose is often prescribed when lower doses are less effective, but it should only be taken under medical guidance. Effects typically begin within 30 to 60 minutes and last several hours. Some people look to buy cenforce 100 as a cost-effective alternative, but it’s important to ensure safe, legitimate sourcing and consult a doctor before use.
