Vardenafil is a medication used to treat erectile dysfunction (ED). It is a phosphodiesterase type 5 (PDE5) inhibitor, also present in Vilitra. When sexually excited, vardenafil relaxes the blood vessels in the penis, improves blood flow, and facilitates erections. Like other ED medications, Vilitra 60 should only be taken under the guidance and supervision of a medical professional. In addition to reviewing any risks or contraindications, they can review your medical history and determine the appropriate dosage for you. As with other PDE5 inhibitors, vardenafil might have unfavorable side effects that include headache, flushing, nasal congestion, dizziness, and indigestion.
