A guy with erectile dysfunction is unable to get and/or sustain an erection strong enough for sexual activity. An efficient medication for treating erectile dysfunction (ED) in men is Fildena 150 mg. As directed by your physician, Fildena 150 tablets may be taken with or without meals. It is advised to take the pill of Fildena 150 mg 30–60 minutes before sexual activity. But you can also take it four hours prior to having sex. Avoid taking alcohol or fatty meals when using Fildena 150 medication.
