Section 4.6 has been updated with worldwide post marketing experience. In summary, pregnancy and lactation information is now detailed under individual subheadings. Limited pregnancy data do not suggest causal relationship between 'Singular' and limb defect malformations that have been rarely reported. Studies in rats show montelukast is excreted in milk. Not known if excreted in human milk. 'Singulair' may be used during pregnancy and in nursing mothers only if considered clearly essential.

Section 4.5: Previously included a caution on inhibition of drugs metabolised by CYP 2C8 (eg. paclitaxel, rosiglitazone, and repaglinide) but that no in vivo interaction studies had been performed.
New information is now available from an interaction study and the statement has been revised to the following

However, data from a clinical drug-drug interaction study involving montelukast and rosiglitazone (a probe substrate representative of drugs primarily metabolised by CYP 2C8) demonstrated that montelukast does not inhibit CYP 2C8 in vivo. Therefore, montelukast is not anticipated to markedly alter the metabolism of drugs metabolised by this enzyme (eg., paclitaxel, rosiglitazone, and repaglinide)'.
 

Section 4.9:

Mainly  editorial changes and updated in line with post-market reports and most frequently occurring AEs consistent with montelukast safety profile. Some AE terminology re-defined. Previously: thirst, somnolence, mydriasis, hyperkinesia, abdominal pain.

Now: abdominal pain, somnolence, thirst, headache, vomiting, and psychomotor hyperactivity.
