Antibiotics And False Negative Urine Test

Updated

I'm on the butrans 20 mg patch and had been taking cephalexin and clindamycin for an abscessed tooth for over 2 weeks. My urine screening came back showing that I had no methylphenidate or suboxone in my urine. I've been consistent on keeping my patch on for 7 days and changing when due. I take 60 mg of methylphenidate daily and I've never failed in 3 years. Could these antibiotics be the reason why?
