Ask about a prescription
for antimalarial drugs if you will be visiting an area that has
malaria. This includes large
areas of Central and South America, Haiti and the Dominican Republic, Africa,
the Indian subcontinent, East Asia, Southeast Asia, the Middle East, and many
South Pacific islands.
You may need to take one of several different preventive
medicines, depending on the type of malaria parasite in that part of the world.
These medicines need to be taken daily during your travels and for a specified
time after you return. It is important to take all the tablets you were given.
This may mean taking antimalarial tablets for several weeks after you get home.
