A common prescription drug used to treat male erectile dysfunction (ED) is Fildena Professional 100 mg. Sildenafil Citrate, which is an ingredient in it, helps men get and keep a hard erection during sexual activity by boosting blood flow to the penile area. The convenient sublingual form of this tablet dissolves rapidly under the tongue, enabling it to function more quickly than conventional ED medications. The effects might linger for up to four or six hours and often start within fifteen to thirty minutes. The best time to take Fildena Professional 100 mg is approximately 30 minutes before scheduled intimacy; nevertheless, it should not be taken more than once daily.
