Chemoprophylaxis
For malaria prophylaxis the stated dose of Lariam should be given once weekly, always on the same day.
In order to ensure, before arrival in endemic area, that Lariam administration is well tolerated, it is 
recommended to start chemoprophylaxis with Lariam 10 days before departure (i.e. first intake 10 days 
before departure and 2nd intake 3 days before departure). Subsequent doses should be taken once a 
week (on a fixed day).
Treatment should be continued for 4 weeks after leaving a malarious area (minimum treatment period 6 
weeks). The maximum recommended duration of administration of Lariam is 12 months.
The recommended chemoprophylactic dose of Lariam is approximately 5 mg/kg bodyweight once weekly. 
The following dosage schedule is given as a guide: 


Adults and children of more than 45 kg bodyweight  1 tablet
Children and adults weighing less than 45 kg
5 – 19 kg ¼ tablet 1/ 4 tablet
20 – 30 kg ½ tablet 1/ 4 tablet

Method of administration
The daily dose should be taken once daily with food or a
milky drink (to ensure maximum absorption) at the same

vomiting within 1-hour of dosing a repeat dose should
