Many men fail to respond to Fildena 100 pills because they are taking them improperly, according to new research. A Spanish study found that 69 percent of the guys who were unable to achieve an erection while taking ED drugs weren't taking the meds correctly. Researchers offered them a "re -education" program to help them understand how to use their meds properly. They responded favorably to the program, and 77 percent reported having better results with their ED medication.

There are several different PDE5 inhibitors on the market, including sildenafil, tadalafil and vardenafil. They're all available by prescription and are able to help men get erections during sexual intercourse.

Fildena is a safe drug to use when used at the right dose, according to your doctor’s instructions. However, it can have side effects if taken in excess.
