My 3 yr old was put on viravan 1 tsp 2x a day. He turned into a monster child. I would be very cautious with theis med!!!!It is very potent! I check the label after I noticed how wild he became and it said only 1/2 tsp for his age. Well, he had been on it for 3-4 days, so I just stopped it all together. His cough is back, but no way will I put him through that again ...ever!! He is still crazy from it. Very aggressive and no reaction to correctioon what so ever. He is usually a very well mannoer child, and I hope thiss goes away soon!! GOOD LUCK!
