Filitra, a medication primarily used to treat erectile dysfunction, has a specific time limit for taking it due to how it interacts with the body and its active ingredients. Filitra contains vardenafil, which works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), leading to increased blood flow to the penis when sexually aroused. The Filitra medication typically starts to work within 30 to 60 minutes and can last for about 4 to 5 hours. To maximize its effectiveness and minimize potential side effects, it is recommended to take Filitra about 1 hour before anticipated sexual activity. Taking it beyond the recommended time frame could either reduce its efficacy or increase the risk of adverse effects. Therefore, adhering to the prescribed time limit ensures the medication works safely and effectively.
