Fildena 50, which contains the active ingredient sildenafil citrate (the same compound found in Viagra), typically has a half-life of around 3 to 5 hours in the human body. This means that within this timeframe, half of the drug's active substance is metabolized and eliminated. However, the effects of
Fildena 50 mg may last up to 4 to 6 hours, depending on individual factors like age, metabolism, liver function, and other medications taken concurrently.
Although the drug starts to diminish in concentration after a few hours, traces can remain detectable in the system for more than a day. The drug is primarily metabolized by the liver via the CYP3A4 enzyme, and its elimination is mostly through the feces and urine. It’s important to note that food—especially high-fat meals—can delay its absorption and slightly alter the duration of effect. For optimal results, Fildena should be taken about 30 to 60 minutes before sexual activity. Always consult with a healthcare provider before use, especially if underlying health conditions exist.
