4.6 Pregnancy and lactation

Although adequate and well-controlled studies in pregnant women have not been performed, the Collaborative Perinatal Project monitored 197 mother-child pairs exposed to guaifenesin during the first trimester. An increased occurrence of inguinal hernias was found in the neonates. However, congenital defects were not strongly associated with guaifenesin use during pregnancy in 2 large groups of mother-child pairs.


Guaifenesin is excreted in breast milk in small quantities.

Caution should therefore be exercised by balancing the potential benefit of treatment against any possible risks.

5. Pharmacological properties

Go to top of the page
5.1 Pharmacodynamic properties

Guaifenesin has an expectorant action which increases the output of respiratory tract fluid by reducing adhesiveness and surface tension. The increased flow of less viscid secretions promotes ciliary action and facilitates the removal of mucus. This changes an unproductive cough to a cough that is more productive and less frequent.

Pharmacotherapeutic group: Expectorant

ATC code: RO5CAO3

Go to top of the page
5.2 Pharmacokinetic properties

Guaifenesin is well absorbed from the gastro intestinal tract following oral administration. Guaifenesin has a plasma half-life of approximately 1 hour. It is rapidly hydrolyzed (60% within seven hours) and then excreted in the urine, with beta-(2-methoxyphenoxy)-lactic acid as its major urinary metabolite
