My son is 10 and is almost tic free when he takes 500 mg Primrose Oil 2 times daily (over the counter) and .5 mg Guanfacine (a very small doseage of blood pressure med also called Tenex) He weighs just 54 pounds so your son might benefit by more. There is no explaination about the Primrose Oil, but the doctor said to keep giving it to him. The brain is made up of fat and water and this oil (fat) seems to be something that he needs for the brain. He is taking other prescriptions for other issues but none ever addressed the tics like these.
