When and How to Take This Medication

Some general considerations to keep in mind during treatment with dextromethorphan include the following:
  • This medication comes in many different strengths and forms. It is usually taken every 4 to 12 hours, but the specific directions for each individual product can vary substantially. Make sure to refer to the directions for your specific dextromethorphan medication.
  • It generally does not matter if you take dextromethorphan with or without food. Try taking it with food if it seems to upset your stomach.
  • Do not use a household spoon to measure liquid dextromethorphan. Household spoons are not accurate enough, so you may get the wrong dose. Use the measuring spoon or dosage cup that comes with the medicine, or ask your pharmacist for an appropriate measuring device.
  • If you are using the strips, allow them to dissolve on your tongue.
  • If you are using the lozenges, let them dissolve in your mouth. Do not swallow them whole.
  • For the medication to work properly, it must be taken as prescribed.
