Guafenesin is an expectorant, a custom-made pharmacy drug widely prescribed by physicians for treatment of congestion due to allergies, common colds, bronchitis, and infection. Guafenesin works by loosening congestion and breaking it up so it can be coughed through the mouth and thus provide for better breathing.
Guafenesin is often given as a liquid medication but may also be administered via extended-release and controlled-release tablets and capsules. Never break, split, or crush capsules or tablets as this may cause a potential overdose. Drink plenty of water while taking this drug. If you are having issues with upset stomach, take with food. Do not give guafenesin to any child under the age of 6 years unless instructed to do so by your child's pediatrician or primary care physician. Some extended-release type capsules and tablets may be contraindicated for use by anyone under the age of 12 years, so ask your physician before administering to anyone 12 years or younger.
It is possible to encounter some side effects while using guafenesin. If you think you are experiencing any side effects that are lingering or growing in intensity, contact your physician right away. Common side effects seen with guafenesin are:
