Yes, the effects of Fildena 100 mg are dose-dependent, meaning its effectiveness and side effects are influenced by the dosage taken. Fildena contains sildenafil citrate, a PDE5 inhibitor that increases blood flow to the penis, helping to achieve and maintain an erection. At a 100 mg dose, Fildena typically provides stronger and longer-lasting results compared to lower doses like 25 mg or 50 mg.

However, increasing the dose does not always mean better results—it may increase the risk of side effects such as headaches, dizziness, flushing, nasal congestion, or vision disturbances. For men with mild erectile dysfunction, a lower dose might be effective and safer. On the other hand, men with more severe ED may require the 100 mg dose for optimal results. It is important to note that Fildena should only be used under medical supervision, as individual response, age, and other health conditions affect the ideal dosage.
