Levitra | Healthcare and Science Focus:
Levitra, known generically as vardenafil, is used to treat erectile dysfunction (ED) in men by enhancing blood flow to the penis during sexual stimulation. As a PDE5 inhibitor, it typically starts working within 30 minutes to an hour, with effects lasting four to five hours. It’s prescribed when other treatments like sildenafil or tadalafil are unsuitable. Sexual stimulation is necessary for effectiveness, and it doesn’t permanently cure ED or increase sexual desire. Medical guidance is crucial due to possible interactions and side effects such as headaches or dizziness.
