Vardenafil, like other PDE5 inhibitors, can cause side effects. The most common are headache, flushing, nasal congestion, and indigestion. These typically are mild and temporary. However, more serious, though rare, side effects exist, and require immediate medical attention.
Cardiovascular Risks
Vardenafil can lower blood pressure. Individuals with pre-existing heart conditions, such as angina or uncontrolled hypertension, should discuss vardenafil use with their doctor. Sudden vision loss or hearing loss necessitates immediate medical help. These are rare but potentially serious side effects.
Other Potential Side Effects
Priapism, a prolonged and painful erection lasting more than four hours, requires immediate medical intervention. Less common side effects include back pain, muscle aches, dizziness, and changes in vision (blurred vision, increased sensitivity to light). Allergic reactions, while infrequent, can manifest as skin rash, itching, or swelling. If you experience any unusual symptoms, contact your healthcare provider immediately.
Medication Interactions
Important: Vardenafil interacts with certain medications, particularly nitrates (used to treat angina). Combining them can dangerously lower blood pressure. Inform your doctor about all medications, including over-the-counter drugs and supplements, before starting vardenafil. Grapefruit juice can also interfere with vardenafil metabolism, increasing its levels in the blood and potentially causing side effects. Avoid grapefruit juice while taking vardenafil.
