4.4 Special warnings and precautions for use

The solvent contains the preservative benzyl alcohol, which may cause anaphylactoid reactions.

Intravenous administration of the preservative benzyl alcohol has been associated with serious adverse events, and death in paediatric patients including neonates characterized by central nervous system depression, metabolic acidosis, gasping respirations, cardio-vascular failure and haematological anomalies (“gasping syndrome”). The minimum amount of benzyl alcohol at which toxicity may occur is not known. Use only if it is necessary and if there are no alternatives possible. If given in high volumes, should be used with caution and preferably for short term treatment in subjects with liver or kidney impairment because of the risk of accumulation and toxicity (metabolic acidosis).

Premature and low-birth weight infants may be more likely to develop toxicity.

Benzyl alcohol containing products should not be used in pre-term or full-term neonates unless strictly necessary because of the risk of severe toxicity including abnormal respiration (“gasping syndrome”).

Benzyl alcohol can cross the placenta and has the potential for toxicity in the newborn. Medicines containing benzyl alcohol should therefore be avoided in pregnant women at or near term (see section 4.6).
