Filitra 20 mg contains vardenafil, a PDE-5 inhibitor prescribed to treat erectile dysfunction (ED). It can improve sexual performance for men whose difficulty achieving or maintaining an erection is related to ED. Vardenafil works by increasing blood flow to the penis during sexual stimulation, helping produce and maintain an erection suitable for sexual activity.

Vardenafil does not directly increase sexual desire or libido. Sexual stimulation is still necessary for the medicine to work. It also does not permanently cure ED; its benefit occurs when the medicine is active in the body.

For most men, the recommended starting dose is 10 mg, taken approximately 60 minutes before sexual activity. Depending on effectiveness and tolerability, a healthcare professional may increase the dose to Filitra 20 mg. It should not be taken more than once in 24 hours.

Common side effects include headache, flushing, nasal congestion, indigestion, and dizziness. Vardenafil can also lower blood pressure and has important interactions with other medicines. It must not be combined with nitrate medicines, such as nitroglycerin, because this can cause a dangerous drop in blood pressure.

Therefore, Filitra 20 mg may improve erectile performance when appropriately prescribed, but it should be used at the recommended dose and after checking for medical conditions and drug interactions. An erection lasting more than four hours requires immediate medical attention.
