What happens if I miss a dose (Coricidin HBP Maximum Strength Flu, Mapap Cough & Sinus Formula, Triaminic Flu Cough & Fever, Triaminic Multi-Symptom Fever, Tylenol Childrens Plus Cough & Runny Nose)?

Since cough or cold medicine is usually taken only as 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. If it is almost time for your next dose, skip the missed dose and take the medicine at your next regularly scheduled time. Do not take extra medicine to make up the missed dose.

What happens if I overdose (Coricidin HBP Maximum Strength Flu, Mapap Cough & Sinus Formula, Triaminic Flu Cough & Fever, Triaminic Multi-Symptom Fever, Tylenol Childrens Plus Cough & Runny Nose)?

Seek emergency medical attention if you think you have used too much of this medicine.

Overdose symptoms may include dry mouth, feeling restless or nervous, dizziness, drowsiness, nausea, vomiting, diarrhea, stomach pain, loss of appetite, increased sweating, vision changes, fast heart rate, warmth or tingly feeling, hallucinations, seizure (convulsions), or coma.

What should I avoid while taking acetaminophen, chlorpheniramine, and dextromethorphan (Coricidin HBP Maximum Strength Flu, Mapap Cough & Sinus Formula, Triaminic Flu Cough & Fever, Triaminic Multi-Symptom Fever, Tylenol Childrens Plus Cough & Runny Nose)?

Do not use any other cough, cold, pain, or allergy medication without first asking your doctor or pharmacist. Acetaminophen (sometimes abbreviated as "APAP"), chlorpheniramine, and dextromethorphan are contained in many cold, pain, and allergy medicines available over the counter. If you take certain products together you may accidentally take too much of a certain drug. Read the label of any other medicine you are using to see if it contains acetaminophen, APAP, chlorpheniramine, or dextromethorphan.

Avoid drinking alcohol. It can increase the risk of liver damage while you are taking acetaminophen. If you drink more than three alcoholic beverages per day, do not take acetaminophen without your doctor's advice, and never take more than 2 grams (2000 mg) of acetaminophen per day.

This medication can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Tell your doctor if you regularly use other medicines that make you sleepy (such as cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by chlorpheniramine.
