Acetaminophen is a less potent pain reliever that increases the effects of hydrocodone. Mitchell JR, Jollow DJ, Potter WZ, Davis DC, Gillette. Hydrocodone is in a group of drugs called narcotic pain relievers.

This report re-emphasises the need for therapeutic drug monitoring whenever these two drugs are used together. Metabolic oxidation of acetaminophen (Paracetamol) mediated by cytochrome P-450. Acetaminophen and hydrocodone is a combination medicine used to relieve moderate to moderately severe pain. Acetaminophen, when given orally for several days, increased the clearance of chloramphenicol, perhaps by increased glucuronidation. Significant differences were observed in mean (SD) peak serum chloramphenicol concentration (-9.7 (3.2) mg/l), mean (SD) apparent volume of distribution (+225 (162) ml/kg), mean (SD) chloramphenicol half life (-1.9 (1.1) hours), mean (SD) chloramphenicol clearance (+236 (94) ml/kg/h), mean (SD) area under the curve (-83.5 (33.0) mg/l/h), and mean (SD) elimination constant (+0.34 (0.13) h-1) between samples obtained before and during treatment with acetaminophen. Vellani V, Mapplebeck S, Moriondo A, Davis JB, McNaughton PA. To confirm one of these findings we studied the clearance of chloramphenicol and its metabolites using high pressure liquid chromatography in five patients (ages 2.5 to 5 years) before and during oral treatment with acetaminophen (50 mg/kg/day). paracetamol (acetaminophen), a very widely used analgesic with a lesser anti-inflammatory. Acetaminophen has been reported either to prolong or not to affect the clearance of chloramphenicol. Upon questioning he tells you that he takes 1000 mg of Tylenol four times a day at home for his back and knee.
