4.4 Special warnings and precautions for use

treatment with corticosteroid antibiotic combinations should not be continued for more than 7 days in the absence of any clinical improvement, since prolonged use may lead to occult extension of infections due to the masking effect of the steroid. Prolonged use may also lead to skin sensitisation and the emergence of resistant
organisms. Prolonged use may lead to the risk of adrenal suppression in infants.
Aminoglycosides antibiotics may cause irreversible, partial or total deafness when given systemically or when applied topically to open wounds or damaged skin. This effect is dose related and is enhanced by renal or hepatic impairment.
Although this effect has not been reported following ocular use, the possibility should be considered when high dose topical is given to small children or infants.

None relevant to topical use

4.6 Fertility, pregnancy and lactation
Safety for use in pregnancy and lactation has not been established. There is inadequate evidence of safety in human pregnancy. Topical administration of corticosteroids to pregnant animals can cause abnormalities of foetal development including cleft palate and intrauterine growth retardation. There may therefore be a very small risk oLsuch effects in the human oetus. There is a risk of foetal
ototoxicity if aminoglycoside antibiotics preparations are administrated during pregnancy.
