4.6 Fertility, pregnancy and lactation


As with all medication caution should be exercised especially during the first trimester of pregnancy. Cumulative experience with sodium cromoglicate suggests that it has no adverse effects on fetal development. It should only be used in pregnancy where there is a clear need.


It is not known whether sodium cromoglicate is excreted in the breast milk but on the basis of its physico-chemical properties this is considered unlikely. There is no information to suggest that the use of sodium cromoglicate has any undesirable effects on the baby.

None known.

4.8 Undesirable effects

Nausea, skin rashes and joint pains have been reported in a few cases.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via Yellow Card Scheme at: or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose

As Nalcrom is only absorbed to a minimum extent, no action other than medical supervision should be necessary.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Antiallergic agents, excluding corticosteroids, ATC Code: A07EB01

Sodium cromoglicate inhibits the release from mast cells of mediators of the allergic reaction. In gastrointestinal allergy the release of mediators can result in gastrointestinal symptoms or may allow absorption of antigenic material leading to systemic allergic reactions.

Animal studies have shown that sodium cromoglicate has a very low order of local or systemic toxicity.
