Other Comments
Administration advice:
- Administer with food; although patients with acute malaria are often averse to food, encourage patients to resume normal eating as soon as food can be tolerated as this improves absorption of each component.
- For patients unable to swallow the tablets (e.g., infants, children), crush tablet(s) and mix with a small amount of water (1 to 2 teaspoons) in a clean container for administration immediately prior to use; rinse the container with more water and swallow the contents; whenever possible, follow this crushed tablet preparation with food/drink (e.g., milk, formula, pudding, broth, porridge).
- If vomiting occurs within 1 to 2 hours after dosing, administer a repeat dose; if the repeat dose is vomited, use an alternative antimalarial for treatment.
