Extra Super Vidalista is commonly used as part of a class of drugs called as phosphodiesterase type-5 inhibitors for adult male erectile dysfunction. It can occasionally induce side symptoms such as headache, nausea, dizziness, indigestion, and upset stomach. Most of these adverse effects are temporary and don't need to be treated by a doctor. Conversely, if these adverse effects persist over time, you should speak with your doctor. It is best to dissolve it by putting it under the tongue or in the mouth. Observe the directions on the label as instructed by the doctor. Pour the Extra Super Vidalista into half a glass of water, then sip the concoction immediately.
