Prevomax® should be administered subcutaneously or intravenously once daily at a dose of 1mg per kg bodyweight (1mL per 10kg bodyweight). Treatment may be repeated for up to 5 consecutive days.

For prevention of nausea and vomiting, Prevomax® should be administered more than 1 hour in advance. The duration of effect is approximately 24 hours and therefore treatment can be given the night before administration of an agent that may cause nausea or emesis eg. chemotherapy. Injecting the product at refrigerated temperatures may reduce pain at the time of injection.

Use the contents within 56 days of first broaching the vial.


Available in a 20mL multi-use vial.
