Is Concerta an "AS NEEDED" medication?

There are two schools of thought on this. Some feel it should be given daily as they need it for focus for school and also on weekends for interaction with their peers and others. Others feel it is good to give the child "breaks" from the medication. My sons were ADD and ADHD as well. My one who is ADD took meds only while at school since he only needed the drug to help him focus. His behavior was not an issue. My younger son was very hyperactive and needed the medication 24/7 for the first several years. Once he was a little older he matured and developed better coping and I started allowing him to go off over the weekend and on school breaks and over the summer. Once school began again, he started right back on his dose with no problems. I did this because the medication took his appetite away so much and he was already small for his age. This helped him catch up a bit on his growth. I never had trouble starting him right back on it. I think it is really parental preference as to whether or not you want to give it every day or if you want to administer it only during school. I have heard pro's and con's for both ways.
