Vardenafil is a medication primarily used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, facilitating an erection. This effect occurs because Vardenafil inhibits an enzyme called phosphodiesterase-5 (PDE5), allowing for increased levels of cyclic guanosine monophosphate (cGMP), a crucial molecule for penile erection.
Dosage and Administration
Vardenafil comes in different dosages, typically ranging from 5mg to 20mg. Your doctor will determine the appropriate dosage based on your individual health and medical history. It’s usually taken as needed, about 25-60 minutes before sexual activity. It’s crucial to follow your doctor’s instructions precisely. Do not exceed the recommended dose.
Potential Side Effects
Like all medications, Vardenafil can cause side effects. Common side effects include headache, flushing, nasal congestion, and indigestion. More serious, though rare, side effects include vision changes (such as blurred vision or changes in color perception) and sudden hearing loss. Seek immediate medical attention if you experience any serious side effects.
Important Considerations
Vardenafil interacts with certain medications, particularly nitrates. Combining Vardenafil with nitrates can cause a dangerous drop in blood pressure. Inform your doctor about all medications you are currently taking, including over-the-counter drugs and supplements. Pre-existing heart conditions also require careful consideration before using Vardenafil. Always consult your doctor before starting any new medication, including Vardenafil, to ensure it’s safe for you.
