My son who is 3 yrs. Old is very hyperactive but a neuro has prescribed sizodon 0.5 mg. 1 tab. At night for my son so that he will calm down and listen to us. He also has speech delay. V are giving the same by mixing in pediasure for the past 4 months but very few days only v can notice the change in him. Now also sometimes he becomes very excited and jumps and troubles us by harming us. Doen t understand others pains. Will this sizodon create any other side effect in future.Pls. Let me know doctor. Shall i continue it for another 3 months as originally prescribed by doctor.
