I'm prescribed 70mg vyvanse, plus have anemia and 50% less blood levels in my body than a regular person. i have been coming up positive with methamphetamine! i don't ever take that drug, yet since mt vyvanse increased i'm positive for meth?

Yes, Vyvanse is an amphetamine that will turn your urine positive. Make sure the testing entity is aware of your current prescriptions.

Discuss your concerns with your Physician who prescribed Vyvanse. Vyvanse is prescribed for ADHD, usually. Did you ask to have another blood test, since you were positive for Meth. Ask your Physician for assistance, and possible explanation.

Prior to any drug testing a full disclosure of one's current medications and who is prescribing them should be done. This can alleviate potential accusations of illicit drug use where prescription medications are being used and are under review of the prescriber as is appropriate.
