One drug used to treat erectile dysfunction (ED) is called Fildena 200. Sildenafil citrate, the active component, is a member of the phosphodiesterase type 5 (PDE5) inhibitors pharmacological class. When a man is sexually aroused, this medicine helps him get and keep an erection by boosting blood flow to the penis. Never begin or cease taking any medication without first seeing your physician. For the doctor to notify you of any potential drug interactions, you should let them know about any other prescriptions you take, including over-the-counter drugs that might intensify the effects of Fildena and dietary supplements like vitamins, minerals, and herbal remedies.
