Guaifenesin thins the mucus in the air passages and makes it easier to cough up the mucus and clear the airways, allowing you to breathe more easily. It relieves the coughs of colds, bronchitis, and other lung infections.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Guaifenesin comes as a regular and extended-release (long-acting) tablet and capsule and liquid to take by mouth. Follow the directions on the package or on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take guaifenesin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Do not break, crush, or chew extended-release tablets and do not open extended-release capsules; swallow them whole.
Drink plenty of fluid while taking this medication (unless your doctor has directed you to limit the amount of fluid you drink). Guaifenesin comes alone and in combination with antihistamines, cough suppressants, and decongestants. Ask your doctor or pharmacist for advice on which form is best for your symptoms.
If your symptoms do not improve within 7 days or if you have a high fever, rash, or persistent headache, call your doctor.
Before taking guaifenesin,
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
Although side effects from guaifenesin are not common, they can occur. Tell your doctor if any of these symptoms are severe or do not go away:
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Throw away any medication that is outdated or no longer needed. Talk to your pharmacist about the proper disposal of your medication.
In case of overdose, call your local poison control center at 1-800-222-1222. If the victim has collapsed or is not breathing, call local emergency services at 911.
Keep all appointments with your doctor.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
