Medicines to Prevent Malaria?

QUESTION

Which medicines are used to prevent malaria?

ANSWER

There are a number of drugs used to prevent malaria infection, known as malaria prophylactic medication. These vary in terms of how they are taken, how long they are taken for, how much they cost and the typical side effects people experience while they are taking them. In addition, some are recommended more highly for certain types of malaria or certain regions of the world, due primarily to the emergence of resistance in certain areas.

The most common forms of malaria prophylaxis used are doxycycline, atovaquone/proguanil (sold under the brand name Malarone), chloroquine (sold as Aralen) and mefloquine (sold as Lariam). More information on these, on other types of prophylaxis and malaria prevention in general can be found on our Malaria Prevention page.

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…]
