Use this medication exactly as directed on the label, or as it has been prescribed by your
doctor. Do not use the medication in larger amounts, or use it for longer than recommended.
Cold medicine is usually taken for only a short time until your symptoms clear up.
Always ask a doctor before giving cough or cold medicine to a child. Death can occur from the misuse of cough or cold medicine in very young children.
Measure the liquid form of this medicine with a special dose-measuring spoon or cup, not
a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
The chewable tablet should be chewed before you swallow it.
Talk with your doctor if your symptoms do not improve after 7 days of treatment, or
if you have a fever with a headache, cough, or skin rash.
This medication can cause you to have unusual results with allergy skin tests. Tell any
doctor who treats you that you are taking an antihistamine.
If you need to have any type of surgery, tell the surgeon ahead of time if you have taken a
cold medicine within the past few days.
Store this medicine at room temperature, away from heat, light, and moisture.
What happens if I miss a dose?
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?
Seek emergency medical attention if you think you have used too much of this
medicine.
Overdose symptoms may include feeling restless or nervous, nausea, vomiting, stomach
pain, dizziness, drowsiness, dry mouth, warmth or tingly feeling, or seizure (convulsions).
What should I avoid while taking chlorpheniramine and dextromethorphan?
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.
Avoid becoming overheated or dehydrated during exercise and in hot weather.
Avoid drinking alcohol while you are taking this medication. Alcohol can add to
drowsiness caused by an antihistamine.
Tell your doctor if you regularly use other medicines that make you sleepy (such as
other cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and
medicine for seizures, depression, or anxiety).
Avoid taking diet pills, caffeine pills, or other stimulants (such as ADHD medications)
without your doctor's advice. Taking a stimulant together with cough or cold medicine can
increase your risk of unpleasant side effects.
Do not use any other over-the-counter cough, cold, allergy, or sleep medication
without first asking your doctor or pharmacist. If you take certain products together you may
accidentally take too much of one or more types of medicine. Read the label of any other
medicine you are using to see if it contains an antihistamine or cough suppressant.
