What is acetaminophen and guaifenesin?
Acetaminophen is a pain reliever and a fever reducer. It is used to treat many conditions,
such as headache, muscle aches, arthritis, backache, toothaches, colds, and fevers.
Guaifenesin is an expectorant. It thins mucous, increases the lubrication of your
respiratory tract (lungs, nose and throat), and improves the removal of mucous.
Acetaminophen and guaifenesin are used to treat headache, aches and pains, fever, and
chest congestion caused by common cold or flu. It also loosens phlegm (mucus) in your chest to
help you breathe more easily.
Acetaminophen and guaifenesin may also be used for purposes other than those listed in
this medication guide.
How should I take acetaminophen and guaifenesin?
Take acetaminophen and guaifenesin exactly as directed. If you do not understand these
directions, ask your pharmacist, nurse, or doctor to explain them to you. Do not crush or chew
the caplet or dissolve it in water.
Take each dose with a full glass of water. Increasing the amount of water you drink
may also help to loosen congestion.
Do not take more of this medication than is recommended. An overdose of this
medication can cause serious harm. The maximum amount of acetaminophen for adults is 1 gram
(1000 mg) per dose and 4 grams (4000 mg) per day. Taking more acetaminophen could cause
damage to your liver. If you drink more than three alcoholic beverages per day, talk to your
doctor before taking acetaminophen and never take more than 2 grams (2000 mg) per day.
Do not take acetaminophen and guaifenesin for longer than 7 days in a row. Stop using
