Fildena CT 50 mg should not be taken with medications that contain nitrates, as this can cause a dangerous drop in blood pressure. It should also be used with caution when combined with other medications for ED, such as other Sildenafil-based products, or drugs for hypertension or HIV. https://www.genericday.com/fildena-ct-50-mg.html
