Vardenafil is used to treat erectile dysfunction.
How Vardenafil works Vardenafil is a phosphodiesterase (PDE-5) inhibitor. It treats erectile dysfunction by increasing blood flow to the penis through the relaxation of muscles in the penile blood vessels. It facilitates the achievement of an erection only when the individual is sexually stimulated.
Common side effects of Vardenafil include flushing (a sense of warmth in the face, ears, neck, and trunk), dizziness, headache, nausea, nasal congestion (stuffy nose), dyspepsia, sinus inflammation, flu-like symptoms, increased creatinine levels in the blood, and back pain.
