Atovakvon / Proguanil Glenmark – Atovaquone / Proguanil hydrochloride uses, dose and side effects


250 mg / 100 mg film-coated tablets 
atovaquone / proguanil hydrochloride

1. What Atovaquone / Proguanil Glenmark is and what it is used for

Atovaquone / Proguanil Glenmark belongs to a group of medicines called antimalarial drugs. They contain two active ingredients, atovaquone, and proguanil hydrochloride.

Atovaquone / Proguanil Glenmark has two uses:

  • to prevent malaria in adults and children weighing more than 40 kg
  • to treat malaria in adults and children weighing more than 11 kg

Malaria is spread by the bite of an infected mosquito that transmits the malaria parasite (Plasmodium falciparum) to the bloodstream. Atovaquone / Proguanil Glenmark prevents malaria by killing this parasite. In people who are already infected with malaria, Atovaquone / Proguanil Glenmark also kills these parasites.

Protect yourself from getting malaria

People of all ages can get malaria. It is a serious disease, but it can be prevented. In addition to taking Atovaquone / Proguanil Glenmark, it is very important that you also avoid getting stung by mosquitoes.

  • Use insect repellent on exposed skin areas.
  • Wear light clothing that covers most of the body, especially after sunset because it is the time when mosquitoes are most active.
  • Sleep in a room with mosquito nets or under a mosquito net that is impregnated with insect repellent.
  • Close windows and doors at sunset, if they are not equipped with mosquito nets.
  • Consider using insect repellent (substrate, spray, electric mosquito coil) to empty the room of insects or discourage mosquitoes from entering the room.

If you need further advice, talk to your doctor or pharmacist.

It is still possible to get malaria even though the necessary precautions have been taken. With some types of malaria infections, it takes a long time for symptoms to appear, so the disease may not be noticed until several days, weeks, or months after you have returned from abroad.

See a doctor immediately if you experience symptoms such as high fever, headache, chills, and fatigue after returning home.

Atovaquone / Proguanil Hydrochloride contained in Atovaquone / Proguanil Glenmark may also be approved for the treatment of other conditions not mentioned in this product information. Ask your doctor, pharmacist, or other healthcare professionals if you have any further questions, and always follow their instructions.
