The inability to achieve or sustain an erection during sexual activity is the hallmark of erectile dysfunction, a problem with male sexual health. A drug called Cenforce 100 is used to treat male impotence or erectile dysfunction (ED). Cenforce aids in firmness by increasing blood flow to the penile area. Preferably, you should take your medication an hour before engaging in sexual activity. If necessary, your doctor may adjust the medicine. If you suspect an overdose, call your doctor right once.
