Fildena 120 is a phosphodiesterase type 5 inhibitor (PDE5) that relaxes blood vessels and improves blood flow to the penile area. The PDE5 enzyme is naturally occurring in males. However, when the level of PDE5 in the body is high, it inhibits blood flow, causing the penile area to become flaccid. When the level of PDE5 is reduced, blood flow is restored and the erection becomes successful.

Whether you have just begun taking Fildena medications or you have been taking it for some time, you may need to know about the potential side effects that can occur. Some of the side effects that may occur are nausea, diarrhea, abdominal pain, headache, or difficulty breathing. If you experience any of these symptoms, you should stop taking Fildena immediately and see a health care professional. The side effects of Fildena 25 are not usually serious. However, if you experience an erection that lasts for more than four hours, or experience pain when attempting to ejaculate, you should contact your doctor. It is important to follow the recommended dosage and to store the medicine properly to avoid its misuse.
