read the package label carefully to be sure that it is the right product for a child of that age.
Do not give dextromethorphan products that are made for adults to children.
Before you give a dextromethorphan product to a child, check the package label to find out how much medication the child should receive. Give the dose that matches the child’s age on the chart. Ask the child’s doctor if you don’t know how much medication to give the child.
If you are taking the liquid, do not use a household spoon to measure your dose. Use the measuring spoon or cup that came with the medication or use a spoon made especially for measuring medication.
If you are using the dissolving strips, place them on your tongue and swallow after they melt.
If you are taking the chewable tablets you can allow them to melt in your mouth or you can chew them before swallowing.
If you are taking the extended-release suspension, shake the bottle well before each use to mix the medication evenly.
If you are taking the lozenges, allow them to slowly melt in your mouth.
Stop taking dextromethorphan and call your doctor if your cough does not get better within 7 days, if your cough goes away and comes back, or if your cough occurs with a fever, rash, or headache.
