DRUG INTERACTIONS: There are no known drug interactions with guaifenesin.

PREGNANCY: 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.

NURSING MOTHERS: It is not known if guaifenesin is secreted into breast milk.

SIDE EFFECTS: Side effects of guaifenesin are uncommon. Nausea, vomiting, headache, and rash may occur.
