How It Works
Guaifenesin may help thin the
mucus, improving drainage of mucus from the nose and
sinuses during
sinusitis.
Why It Is Used
Guaifenesin may be used to treat
symptoms caused by acute or chronic sinusitis. It is usually used along with
antibiotics and home treatment.
How Well It Works
Guaifenesin has not proven to
be effective in reducing symptoms of sinusitis, but it is widely used.
Side Effects
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.
Here are some important things to think about:
- Usually the benefits of the medicine are more important than any minor side effects.
- Side effects may go away after you take the medicine for a while.
- If side effects still bother you and you wonder if you should keep taking the medicine, call your doctor. He or she may be able to lower your dose or change your medicine. Do not suddenly quit taking your medicine unless your doctor tells you to.
Call 911 or other emergency services right away if you have:
- Trouble breathing.
- Swelling of your face, lips, tongue, or throat.
Call your doctor if you have:
Common side effects of this medicine include:
- Diarrhea.
- Headache.
- Nausea or vomiting.
See Drug Reference for a full list
of side effects. (Drug Reference is not available in all systems.)
What To Think About
Guaifenesin is inexpensive and
available without a prescription. There is no evidence showing that it is
effective in treating sinusitis.
Saline (saltwater)
nasal sprays and washes may help clear up a stuffy nose. Both are available at pharmacies without a prescription. A
humidifier may also help thick or dried mucus to drain.
This medicine is often combined with another
medicine such as a cough suppressant or decongestant.
Mucolytics may not be safe for young children or for people who have certain health problems. Before you use them, check the label. If you do use these medicines, always follow the directions about how much to use based on age and in some cases weight.
Taking medicine
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Advice for women
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Checkups
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
