As with all medications during pregnancy, this product should be used with caution especially during the first trimester. There do not appear to be foetal abnormalities in toxicity studies, but this should not mitigate the care to be used with this product. The product should therefore only be used in pregnancy where there is a clear need.
There is no information to indicate that the use of sodium cromoglicate has any undesirable effects on the baby.
It is unlikely that this product would be excreted in breast milk but this has not been fully investigated
Instillation of drops may cause transient alteration of vision. Patients should be advised not to drive or operate machinery until clarity of vision is restored.
Stinging, blurring of vision and burning may occur briefly after instillation, as may local irritation.
Sodium cromoglicate is poorly absorbed through the gastrointestinal tract. In cases of overdosage, no action other than medical observation should be necessary.
Both in-vitro and in-vivo studies suggest that sodium cromoglicate prevents the release of granules that produce allergen-mediated inflammatory reaction in the eye. Sodium cromoglicate appears to inhibit reactions caused by both antigenic and non antigenic stimuli. Sodium cromoglicate has no intrinsic antihistaminic or anti-inflammatory action. Evidence suggests that the effects of the drug may be due to mast cell membrane stabilisation, although the precise mechanism is not known.
Sodium cromoglicate is poorly absorbed from the gastrointestinal tract, with less than 1% being made available by this route.
Systemically absorbed sodium cromoglicate is not metabolised and drug is excreted unchanged in the bile and urine. The drug does not cross the blood- brain barrier.
There is no published information on either mutagenicity or carcinogenicity testing with this drug.
