Fildena 100 is a medication used to treat erectile dysfunction (ED) in men. It contains Sildenafil Citrate, a phosphodiesterase type 5 (PDE5) inhibitor that works by increasing blood flow to the penis, allowing for a sustained erection during sexual stimulation. Fildena 100is taken orally about 30 minutes to an hour before sexual activity and should not be taken more than once per day. It is important to note that Fildena 100 will only work if the user is sexually aroused. It is not a cure for ED and should not be used by individuals who do not have ED. Side effects may include headache, dizziness, flushing, indigestion, and changes in vision or hearing. It is important to talk to a healthcare provider before taking Fildena 100 to determine if it is safe and appropriate for individual use.
