What happens if I miss a dose?
Since cough or cold medicine is taken when needed, you may not be on a dosing schedule. If you are taking the medication regularly, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of acetaminophen can be fatal.
The first signs of an acetaminophen overdose include loss of appetite, nausea, vomiting, stomach pain, sweating, and confusion or weakness. Later symptoms may include pain in your upper stomach, dark urine, and yellowing of your skin or the whites of your eyes.
Overdose symptoms may also include dizziness, drowsiness, feeling restless or nervous, diarrhea, loss of appetite, seizure (convulsions), or coma.
What should I avoid while taking acetaminophen, dextromethorphan, and pseudoephedrine?
This medication may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP), dextromethorphan, and pseudoephedrine are contained in many combination medicines. Taking certain products together can cause you to get too much of a certain drug. Check the label to see if a medicine contains acetaminophen, APAP, dextromethorphan, or pseudoephedrine.
Avoid drinking alcohol. It may increase your risk of liver damage while taking acetaminophen.
