No, Cenforce 100 (sildenafil citrate) does not prevent sexually transmitted infections (STI). Cenforce 100 and other sildenafil-containing drugs are used specifically to treat erectile dysfunction (ED) in men. They operate by increasing blood flow to the penis during sexual stimulation, allowing you to obtain and sustain an erection. In contrast, STIs are illnesses that spread through sexual contact with an infected partner. The only reliable means of STI prevention are to practice safe sex by correctly and consistently using condoms, to be in a mutually monogamous relationship with an uninfected partner, and to get tested for STIs on a regular basis. While Cenforce 100 can help you have an erection, it does not protect against STIs. Prioritizing safe sexual behaviors, as well as the use of ED drugs, is critical for maintaining overall sexual health and lowering the risk of developing or transmitting STIs.
