4.6 Fertility, pregnancy and lactation
Pregnancy
As with all medication, caution should be exercised, especially during the first trimester of pregnancy. Cumulative experience suggests that sodium cromoglicate has no adverse effects on foetal development. It should be used in pregnancy only where there is a clear need.
Breast-feeding
It is not known whether sodium cromoglicate is excreted into human 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.
4.7 Effects on ability to drive and use machines
This preparation may cause transient blurring of vision, following instillation. Do not drive or operate machinery until clarity of vision is restored.
4.8 Undesirable effects
List of adverse reactions
The frequencies of adverse events are ranked according to the following: very common (>1/10), common (>1/100 to < 1/10), uncommon (>1/1,000 to < 1/100), rare (>1/10,000 to < 1/1,000), very rare (<1/10,000), not known (cannot be estimated from the available data).
Eye disorders
Not known: Burning, stinging, blurring of vision or other transient symptoms. 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 professional are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard
4.9 Overdose
Sodium cromoglicate is poorly absorbed through the gastrointestinal tract. Overdosage is very unlikely. In case of overdose no action other than medical observation should be necessary.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Both in-vitro and in-vivo studies have consistently suggested that sodium cromoglycate prevents the release of granules that produce the allergen-
mediated inflammatory reaction in the eye. Sodium cromoglycate appears to inhibit reactions caused by both antigenic and non antigenic stimuli. Sodium cromoglycate has no intrinsic antihistaminic or antiinflammatory activity. Most evidence suggests that the effects of sodium cromoglycate are due to a stabilisation of mast cell membranes, although the precise mechanism remains unknown.
5.2 Pharmacokinetic properties
Due to lipid insolubility, sodium cromoglycate is effective only by topical application and only very small amounts are systemically absorbed in man. Any systemically absorbed drug is excreted unchanged in the bile and urine.
5.3 Preclinical safety data
None available
