If so how much. I see a possible APAP overdose potential? I sometimes take APAP 500mg tabs 2 to relieve pain. When it is ineffective I take 2 Tramadol HCL 50mg tabs. One site mentions Tramadol/Acetamenophen as a tablet. Knowing the potential for hepatic damage with APAP overdose I need to know if the tablets issued by the pharmacy contain APAP.
