Drugs to Treat Pregnant Woman with Malaria

QUESTION:

What are the drugs for a pregnant woman who has malaria for the first to third trimester?

ANSWER:

The treatment of malaria in pregnant women has become more challenging in recent years, as many types of malaria are developing resistance to the standard arsenal of drugs. In locations where the dominant form of malaria is still chloroquine-sensitive, chloroquine can be used safely throughout pregnancy.

However, given the high levels of chloroquine-resistance, other drug regimens may be required. Currently, first-line treatment options for uncomplicated malaria caused by Plasmodium falciparum (many strains of which are resistant to chloroquine), is quinine plus clindamycin (doxycycline is contraindicated in pregnant women). In the second and third trimesters, artesunate plus clindamycin can be administered, or the artemisinin-based combination therapy (ACT) commonly used in that region, although some of these combinations, particularly those containing artemether, have limited safety testing in pregnant women. In general, the paucity of controlled, randomized trials has posed a problem to creating safe and effective recommendations for the treatment of malaria in pregnant women.

Malaria prevention consists of a combination of mosquito avoidance measures and chemoprophylaxis. Although very efficacious, none of the recommended interventions are 100% effective.

Mosquito Avoidance Measures

  • Because of the nocturnal feeding habits of Anopheles mosquitoes, malaria transmission occurs primarily between dusk and dawn.
  • Contact with mosquitoes can be reduced by remaining in well-screened areas, using mosquito bed nets (preferably insecticide-treated nets), using a pyrethroid-containing flying-insect spray in living and sleeping areas during evening and nighttime hours, and wearing clothes that cover most of the body.
  • All travelers should use an effective mosquito repellent. [Read more…]
