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.

Storage requirements:

Store at 20C to 25C (68F to 77F); excursions permitted to 15C to 30C (59F to 86F).
