Acetaminophen (Fervex Rhume) is metabolized (eliminated by conversion to other chemicals) by the liver. Therefore drugs that increase the action of liver enzymes that metabolize Acetaminophen (Fervex Rhume) [for example, carbamazepine (Tegretol), isoniazid (INH, Nydrazid, Laniazid), rifampin (Rifamate, Rifadin, Rimactane)] reduce the levels of Acetaminophen (Fervex Rhume) and may decrease the action of Acetaminophen (Fervex Rhume). Doses of Acetaminophen (Fervex Rhume) greater than the recommended doses are toxic to the liver and may result in severe liver damage. The potential for Acetaminophen (Fervex Rhume) to harm the liver is increased when it is combined with alcohol or drugs that also harm the liver.

Cholestyramine (Questran) reduces the effect of Acetaminophen (Fervex Rhume) by decreasing its absorption into the body from the intestine. Therefore, Acetaminophen (Fervex Rhume) should be administered 3 to 4 hours after cholestyramine or one hour before cholestyramine.

Acetaminophen (Fervex Rhume) doses greater than 2275 mg per day may increase the blood thinning effect of warfarin (Coumadin) by an unknown mechanism. Therefore, prolonged administration or large doses of Acetaminophen (Fervex Rhume) should be avoided during warfarin therapy

Very rarely (and usually mild) skin rashes and palpitations. Sedation and dizziness may occur after the intake of the yellow (night) tablet. In this case it is not advisable for patients who drive or operate machinery at night. Therefore the yellow tablet is recommended at bedtime.
