DM Oral
Generic Name: GUAIFENESIN/DEXTROMETHORPHAN SUSTAINED-RELEASE
TABLET - ORAL
Pronounced: (gweye-FEN-eh-sin/dex-trow-meth-OR-fan)
DM Oral Uses
This combination medication is used to relieve coughs caused by
the common cold, bronchitis, and other breathing illnesses.
Guaifenesin belongs to a class of drugs known as expectorants.
It works by thinning and loosening mucus in the airways, clearing
congestion, and making breathing easier. Dextromethorphan belongs
to a class of drugs known as cough suppressants. It acts on a part
of the brain (cough center) to reduce the urge to cough.
Do not use this medication in children younger than 12 years
unless specifically directed by the doctor. To decrease the risk
for serious side effects, carefully follow all of the doctor's
dosage directions. Do not give other cough and cold medication that
might contain the same or similar ingredients (see also Drug
Interactions section). Ask your doctor or pharmacist about other
ways to relieve cough and cold symptoms (e.g., saline nose
drops/spray, using a humidifier or infant nasal suction bulb).
How To Use DM Oral
Take this medication by mouth with or without food, usually
twice daily or as directed by your doctor.
Swallow the long-acting tablets whole with a full glass of water
(8 ounces or 240 milliliters). Drink plenty of fluids while taking
this medication. Fluids will help to break up mucus and clear
congestion.
Do not crush, chew, or break the tablets. Doing so can destroy
the long action of the drug and may increase side effects.
Dosage is based on your medical condition and response to
therapy.
Use this medication regularly in order to get the most benefit
from it. To help you remember, take it at the same times each
day.
Improper use of this medication (abuse) may result in serious
harm (e.g., brain damage, seizure, death). Do not increase your
dose, take it more frequently, or use it for a longer time than
directed.
If your condition persists or worsens after 7 days, or if you
think you may have a serious medical condition, seek immediate
medical attention.
