Vilitra 60 mg, if it contains vardenafil, can cause nausea. Nausea is a recognized side effect of vardenafil, and studies show that some side effects, including nausea, become more likely as the dose increases. More importantly, 60 mg is far above the usual recommended maximum of Vilitra 60 mg  for vardenafil. The standard starting dose is 10 mg, taken about 60 minutes before sexual activity, with a maximum recommended dose of 20 mg once daily. If you've already taken 60 mg and are feeling nauseous, don't take any more vardenafil today. Seek urgent medical care if you develop severe dizziness/fainting, chest pain, vision changes, or an erection lasting more than 4 hours. If you tell me when you took the 60 mg and what symptoms you're having now, I can help you assess what to do next.
