Treatment for Pregnant Woman with P. Vivax Malaria

QUESTION:

A pregnant woman has vivax malaria what treatment should be given in case of relapse?

ANSWER:

Primaquine, the usual drug given to prevent relapse of P. vivax malaria, is not recommended for pregnant women due to inadequate information about its safety. As such, it is normally recommended to treat the relapses with chloroquine, to cure each malarial episode, until after delivery of the child, after which time the woman should be treated with primaquine.
