... I have been taking Concerta 54 mg for 2 years.For the last 6 months I have been given a urine screen test at my doctor's and it comes back negative for amphetamines. I also had a blood test done last month and it was negative. I KNOW I AM TAKING THE MEDICATION. Has anyone else had this problem?
yes but not concerta, lithium my daughter takes concerta that's why i am reading all of these i take lithium and i get blood taken and they said i dont take it i take 700 mg a day i dont understand it at all lol
Concerta does not show up pos on drug screens, I have been tested SEVERAL times and it always is NEGATIVE
I tested negative and I take my adderall as scheduled twice a day my doctor dont believe me and dropped me as a patient???
