What is the most important information I should know about guaifenesin?

Ask a doctor or pharmacist before using this medicine if you have health problems or use other medications, or if you are pregnant or breast-feeding.

What is guaifenesin?

Guaifenesin is used to reduce chest congestion caused by the common cold, flu, or chronic bronchitis.

Guaifenesin helps loosen congestion in your chest and throat, making it easier to cough out through your mouth.

There are many brands and forms of guaifenesin available. Not all brands are listed on this leaflet.

Guaifenesin may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking guaifenesin?

You should not use guaifenesin if you are allergic to it.

Ask a doctor or pharmacist if it is safe for you to use this medicine if you have other medical conditions.

Ask a doctor before using this medicine if you are pregnant.

You should not breast-feed while using guaifenesin.

How should I take guaifenesin?

Use exactly as directed on the label, or as prescribed by your doctor. Cold or cough medicine is only for short-term use until your symptoms clear up.

Always follow directions on the medicine label about giving cough or cold medicine to a child. Do not use the medicine only to make a child sleepy. Death can occur from the misuse of cough or cold medicines in very young children.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

To use guaifenesin granules, pour out the entire packet onto your tongue and swallow without chewing.

Call your doctor if your symptoms do not improve after 7 days, or if you have a fever, rash, or headaches.

This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using guaifenesin.

Store at room temperature away from moisture and heat. Do not freeze.

What happens if I miss a dose?

Since cough or cold medicine is used when needed, you may not be on a dosing schedule. Skip any missed dose if it's almost time for your next dose. Do not use two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid while taking guaifenesin?

Ask a doctor or pharmacist before using other cough or cold medicines that may contain similar ingredients.

Avoid driving or hazardous activity until you know how this medicine will affect you. Your reactions could be impaired.

What are the possible side effects of guaifenesin?

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Common side effects may include:

  • nausea; or
  • vomiting.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What other drugs will affect guaifenesin ?

Avoid using this medicine with other drugs that cause drowsiness or slow your breathing (such as opioid medicine, a muscle relaxer, or medicine for anxiety or seizures). Ask a doctor or pharmacist before using any other medication, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed in this medication guide.

Where can I get more information?

Your pharmacist can provide more information about guaifenesin.
