    Serious adverse reactions including neurotoxicity, ototoxicity and nephrotoxicity have occurred in patients receiving systemic aminoglycoside therapy. Caution is advised when used concomitantly.

    According to the MHRA/CHM advice, there is an increased risk of ototoxicity when aminoglycosides are administered to patients with mitochondrial mutations, including cases where the patient's aminoglycoside serum levels were within the recommended age. Monitor renal, auditory function, hepatic and laboratory parameters to reduce the risks of adverse reactions.

    Pregnancy and Lactation


    Use netilmicin with caution during pregnancy.

    The manufacturer advises that netilmicin should be administered only after a careful benefit-risk assessment and under strict control. Preclinical studies show no foetal toxicity with topical administration of netilmicin.


    Netilmicin is contraindicated during breastfeeding.

    The manufacturer does not recommend breastfeeding whilst taking netilmicin. Aminoglycosides are excreted in breast milk in small amounts. Effects on exposed infants are unknown.
