The first time i took it I didn't notice any differences but my parents did. The only side effects I initially experienced were a loss of appitite that lasted for about 4 of the 6 hours that the meds are effective. good luck!
So dd (8) was prescribed Concerta 18 mg.The dose may be low, so you may see no real change. They usually start you low and you work your way up. Call the doctor immediatley if she needs an increase. She will lose her appetite until they wear off and she may have rebound. Have you heard of this or read about it here on the boards?
My son has been on concerta since he ended 1st grade and is now entering 6th. We moved up quickly with the milligrams, but it works for him. Don't get hung up on the dosage, it is NOT age based, it is how quickly the person burns it off.
Concerta also may not be her best med choice. DS couldn't handle adderall and strattera. EVeryone is different.
Best wishes!
