What are the side effects of atovaquone/proguanil?

Possible side effects of atovaquone/proguanil are split into common and serious.

Information about taking atovaquone/proguanil at the same time as other medications or herbal supplements

Is there a herbal atovaquone/proguanil?

No. Herbal atovaquone/proguanil does not exist. If you have been marketed such a formulation, it may be fake. Also, it has not been proven that garlic or vitamin B are effective mosquito repellents. Citronella, however, has been shown to repel mosquitoes, but requires applying every 30 minutes which may be impractical.

You can eat and drink normally when taking atovaquone/proguanil. You are advised to take atovaquone/proguanil with food or a milky drink.

What else can I do to help prevent malaria?

It is important to prevent mosquito bites to reduce the risk of getting malaria. Precautions include:

  • Using insect repellents containing DEET
  • Wearing long-sleeved clothes, especially when mosquitos are most active during dusk and dawn
  • Sleep under mosquito nets impregnated with insecticide
  • Keep away from ponds, lakes, puddles, storm drains or wells, where mosquitos like to lay their eggs

Alternatives to atovaquone/proguanil
