To be honest,
Fildena Chewable 100 should first be used for a few weeks to let your body adjust to the drug. After that, it begins to show its effectiveness. This is the reason why Fildena Chewable 100 is mostly prescribed for at least six months. Your doctor will decide whether you should continue using this drug for impotence after this time or not. Sometimes men prefer to take it for more than a year, which means it is safe for long-term use.
