The main reason men take Fildena is to help erectile dysfunction (ED). A phosphodiesterase type 5 (PDE5) inhibitor called sildenafil citrate is in it. When you're physically aroused, sildenafil helps get more blood to your penis, which makes it easier to get an erection. Fildena comes in different doses, like 50 mg, 100 mg, and 200 mg of Fildena Double. This means that each person can customize their dose based on their needs. Most people take it by mouth 30 to 60 minutes before getting sexual. When taking Fildena, you should only do so with the help of a medical professional. Only they can tell you the right dose and address any worries or possible side effects. For safe and successful treatment of ED, it's important to carefully follow their directions. Fildena may have side effects like headaches, itching, or heartburn, just like any other medicine. If you have any concerns, you should talk to your doctor before taking it.
