Vardenafil is the active component in Levitra 10 mg tablets. It is often used to treat erectile dysfunction in men (the inability to obtain or maintain a penile erection sufficient for effective sexual intercourse). Levitra tablets work by relaxing blood arteries, which increases blood flow to specific body locations, particularly the penile region. It is vital to note that sexual excitement is required to determine whether the Levitra tablet is effective. As a result, it should be taken orally and eaten whole with a glass of water between 25 to 60 minutes before sexual activity. The dosage, frequency, and duration of medication must be rigorously followed as prescribed by the doctor.
