Sildenafil citrate is the active ingredient of Fildena Double 200, also known as Fildena Double 200mg. Men with erectile dysfunction may benefit from this medication's ability to regulate blood flow to the pelvic organs and have satisfying sexual encounters. If at all possible, take the pills without food; nonetheless, a little lunch is OK. Therefore, unless a doctor prescribes otherwise, there are no dietary restrictions. Pour half a cup of water into your mouth, then swirl it about for a few seconds. The only thing left to do is swallow the tablets whole, without breaking them.
