Oh god I know exactly how you feel. I have been reading about how medicines stop working and then you have to change and oh god just all the drama. My daughter just recently started on concerta. Its been two weeks and so far so good. Does your son go for behavioral therapy once or twice a week? Is he in special education? If he isnt in therapy maybe that can help. I so understand your frustration I really really do. Just keep trying everything pray and dont give up. As Im telling you this, Im also telling myself this.
Thanks Chels718!! You do the same. No he's not in behavioral therapy, there are not any available in my area. I quit taking him to the counselor because its just simply too expensive, especially now that he has to be seen every thirty days by the nurse and every 90 by the doctor......I will keep praying, you do the same!! Sounds like all the symptoms are back. And his current dose isn't working anymore. It is as if he is not medicated at all, is the way I always describe my son when this happens.
We didn't last long at 54mg of concerta. We were at 72 mgs for a long time. We also use guanfacine for the impulsiveness, like talking, touching, blurting, etc.
Do you think an increase would help? What the doctor allowed me to do was have our son take two 36's.
Honestly, you will never know if this is the answer until you try it.
Call his doctor and discuss. I would also mention guanfacine.
Please let us know how you make out!! 
Please give me some advise. I am at my wits end with my child. My son was diagnosed with ADHD at the age of 5. As a toddler he was kicked out of 3 daycares and then suspended numerous times once in kindergarden and first grade. During those times I was taking him to psycologists and doctors and trying different natural remedies to control his out of control behavior and finally in the first grade I gave up and put him on meds. He started with concerta which worked for a while then stopped. The dosage was increased and it started working again then stopped. The second time the doctor decided to try adderol, which was a nightmare, he became agressive and violent within a week, so we went back to concerta. He was increase a couple more times til he is now on 54mg concerta, and yes, it is now not working again, or is it. I don't give him the meds on weekends or holidays, or when school is out. He was doing fine until winter break when I didn't give it to him the whole break. He went back to school in January and I began to notice behavior problems at home. He is very argumentative, aggrevates his siblings all the time and constantly talks back. I didn't really think anything of it because the teacher had not voiced any concerns and his report card was wonderful, straight A's. Now after having a very difficult time at home with homework I contacted the teacher, who now tells me she IS having problems with him at school and it began after winter break as well. What we both have seen is almost a zombie. He will be looking at you and watching your lips but won't understand a word you are saying. Matter of fact if you ask him, "repeat what I just said", he cannot. It's almost like there is some type of mental block there. We teach him something, which requires going over it about 6-7 times before he gets it and that night or next day, he won't remember. This accompanied with the talking back, agruementativeness, forgetfulness and what appears to be flat out defiance, I consulted his pediatrician. The doctor wants to move him now to Straterra? This medication scares me looking at the blogs and side affects......I'm considering trying natural remedies again, even though they didn't work in the past.....I'm not sure! I just know, as a parent, I am soooo frustrated and ready to burst into tears. I have a 1 year and 2 year old behind him and I can't take much more of this aggrevation!! Any suggestions?!
