Fildena contains sildenafil, a PDE5 inhibitor. In general, do not combine Fildena with another ED medicine on your own, especially another PDE5 inhibitor such as tadalafil (Cialis), vardenafil (Levitra), or avanafil (Stendra). The safety of combining PDE5 inhibitors has not been established, and the combination can increase adverse effects such as low blood pressure, dizziness, and prolonged erection. F FDA Access Data +1 Also, never combine sildenafil with nitrate FILDENA such as nitroglycerin or isosorbide, because the combination can cause a dangerous drop in blood pressure. F FDA Access Data +1 If Fildena isn't working adequately, a clinician can instead consider adjusting the sildenafil dose, changing to a different ED treatment, or investigating other causes of ED. If you tell me which other ED medicine you mean (e.g., tadalafil, vardenafil, or an injection), I can explain the specific interaction and usual medical approach.
