Vilitra 10 mg contains Vardenafil, which is a PDE5 inhibitor similar to Tadalafil (found in Vidalista) and Sildenafil (found in Viagra). It works by increasing blood flow to the penis during sexual arousal, which helps men with erectile dysfunction (ED) achieve and maintain an erection. Why Vilitra 10 mg is not typically used for daily use: On-Demand Use: Vilitra 10 mg is generally designed for on-demand use, meaning it's taken before sexual activity (usually about 30 minutes to an hour before). It’s not intended to be taken daily because it’s formulated for temporary effects rather than continuous use. The 10 mg dose provides a quick, but shorter duration of action (usually 4-6 hours) compared to medications like Tadalafil (which lasts up to 36 hours), which are designed for daily use. Short Duration of Action: Vilitra 10 mg has a shorter half-life (about 4-5 hours) compared to Tadalafil (Vidalista), which can last up to 36 hours. This means that Vilitra 10 mg is effective for a few hours but would need to be taken again if you’re looking for continuous effects, making it less practical for daily use. Medications like Tadalafil (2.5 mg or 5 mg) or Sildenafil (daily low doses) are generally prescribed for daily use because they help provide more consistent, long-term improvements in erectile function. Risk of Overuse or Side Effects: If Vilitra 10 mg were taken daily, there could be a higher risk of side effects such as headaches, flushing, dizziness, or muscle pain, especially because it’s not designed to be used regularly. The daily use of a drug like Tadalafil (at a lower dose) is usually safer for long-term, daily use because it’s formulated for that purpose and has a longer action time at a stable, lower dose. Higher Dose for On-Demand Use: Vilitra 10 mg is typically prescribed at a higher dose (compared to daily-use doses like 2.5 mg or 5 mg of Tadalafil) because it’s intended for occasional use when you know you’ll need it, rather than as a maintenance treatment. For daily use, a lower dose would be preferable to keep a consistent level of the drug in your system without causing undue strain on the body or risk of side effects.
