Guaifenesin is used for the treatment of cough associated with colds and minor upper respiratory tract infections in individuals 12 years and older.

Side effects of guaifenesin are uncommon, but can include:

• Nausea,
• vomiting,
• headache, and
• rash

Guaifenesin may be taken with or without food. The tablets should be taken whole and should not be crushed, chewed, or broken. The recommended dose is 600-1200 every 12h hours up to a maximum of 2.4 g per day. Patients should consult a health care professional if symptoms last more than 7 days.

There are no known drug interactions with guaifenesin.

Although one analysis found a correlation between guaifenesin use in the first trimester of pregnancy and an increased risk of hernia in the fetus, others found no increased risk of fetal malformations. Thus, guaifenesin should be used in pregnancy only if the physician feels that the potential benefits outweigh the potential and unknown risks.

It is not known if guaifenesin is secreted into breast milk.
