Frequently asked questions
Will vardenafil give me an erection automatically?
No. It only works when you are sexually aroused.
How is it different from sildenafil?
It works in a similar way with similar side effects; food and duration differences are small. Your doctor can help you choose.
Can I drink alcohol with it?
Small amounts are usually fine, but heavy drinking reduces its effect and increases dizziness.
