I just received a positive drug test for HTC, Amphetamine and Methamphetamine. The test was done twice with the same results. I am currently on prescription Labetalol HCL, Clonidine HCL, HCTZ/Lisinopril, Metformin HCL, Cholecaleferol and 7 days ago had 1 Fluconazole for a yeast infection. Are these melds giving me a positive result? Please help!
