Steph,
I'm not an expert by far...my son was only diagnosed in June. We've been on meds-two different ones. Not happy with either one of them. Adderall XR gave us huge meltdowns and focalin xr has his sad all the time. Both messed with his appetite and gave him the focus he needed for school.
What i"ve learned on this board is that what works for one person doesn't necessarily work for another. Each child is different and it is trial and error to figure out what's going to work best for your son. If you have a good trusting relationship with the doctor, I would suggest asking them what they suggest and moving from there.
Good luck and God bless
Vicky
As hossiermomma2 said, it is individual for each person. THe goal is to find the best treatment plan for your son's needs. The doc will usually suggest the med(s) that he/she has the most experience with. The stims will have the fastest results so you can tell if they are working (correct dose, correct med) pretty fast. Also, if there are side effects, they are out of the system in a matter of hours. Usually the doc will start at a low dose to check for side effects and then work up to an effective dose.
Some kids do well on the first med they try and others take some work to find a good fit. We have tried a few meds and have had success with concerta and focalin, but prefer the concerta for the smooth release and longer effective time. My oldest loves concerta and how it helps with concentrating in school; and she does not have issues with weight loss. We are now trying straterra for the youngest to see if we can get 24/7 coverage and not worry about weight loss and maybe cover her anxiety better. If it does not work, we will go back to concerta with summer breaks for weight gain. We are just trying to get the most out of the treatment.
Good luck, you will find your way through this.
