Fildena CT 50 is a medication used to treat erectile dysfunction (ED) in males. It contains sildenafil citrate, the active ingredient found in the brand-name medication Viagra. I don't have firsthand knowledge with drug effects as a language model, but I can give you a general overview of Fildena CT 50 based on its composition and intended use. Fildena CT 50 is the lowest available dose of this medication and is frequently used for people who have never used this type of medication before or who have ED but are otherwise healthy. It is crucial to note that this medication should only be taken as directed by a doctor. Fildena CT 50 effects typically last for 4-6 hours after taking the prescription, though this varies by individual. Headaches, dizziness, flushing, and stomach upset are all common side effects. Serious adverse effects, such as vision issues or hearing loss, are rare but possible.
