Fildena 100 mg contains Sildenafil Citrate, a medication commonly used to treat erectile dysfunction (ED). While it's generally safe when used as directed, there are some potential side effects that users should be aware of, including rare effects on hearing. While Fildena 100 mg is effective for treating ED, it may cause rare hearing-related side effects in some individuals. To minimize risk, use the medication under medical supervision and report any hearing issues as soon as they occur. If you experience sudden hearing changes or ringing in the ears after taking Fildena, stop using the medication and seek medical attention immediately. Early intervention may help prevent permanent hearing damage.
