What Causes False Positive Drug Test Results For Benzodiazepines While On Sulfamethoxazole?
My son is in a recovery house and he got tested and he thinks he got positive results for Benzos. He was extremely upset cuz he said he didn’t take anything. He is on 2 antibiotics called Cephalexin Bacrim D table 500 mg and Sulfamethoxazole - xazole -temp-SD. Could this have interfered w drug testing?
