Vriligy 60 is generally taken on demand, approximately 1–3 hours before sexual activity, and should not normally be taken more than once in 24 hours. The usual starting dose is 30 mg. A 60 mg dose may be considered by a healthcare professional when 30 mg does not provide sufficient benefit and is well tolerated. Common side effects include nausea, headache, dizziness, diarrhea, dry mouth, and difficulty sleeping. Dapoxetine can cause a sudden decrease in blood pressure or fainting, particularly when standing up quickly.
