250/100 mg film-coated tablets
atovaquone / proguanyhydrochloride

What Malastad is and what it is used for

Malastad belongs to a group of medicines called malaria medicines. Each tablet contains two active substances, atovaquone, and proguanil hydrochloride.

Malastad has two uses:

  • prophylaxis (prevention) against malaria in adults and children weighing more than 40 kg.
  • treatment of malaria in adults and children weighing more than 11 kg.

Malaria is spread through the bite of infected mosquitoes, which carry the malaria parasite ( Plasmodium falciparum ) further into the bloodstream. Malastad kills the parasite and can thus prevent malaria from developing ( prophylaxis ). Malastad also kills Plasmodium falciparum parasites in individuals who have already developed malaria.

Atovaquone and proguanil hydrochloride found in Malastad 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.

Protect yourself from malaria

  • In addition to taking Malastad, it is very important that you also make sure to avoid mosquito bites. Use insect repellent on exposed skin surfaces .
  • Wear light clothing that covers most of the body , especially after sunset because that is when the mosquitoes are most active.
  • Sleep in a screened room or under a mosquito net impregnated with insect repellent.
  • Close windows and doors at sunset if mosquito nets are missing.
  • Consider using insect repellent (substrate, spray, plug) to remove mosquitoes before nightfall or to prevent mosquitoes from entering.
  • If you need further advice , talk to your doctor or pharmacist.

However, you can get malaria even though all precautions have been taken. In some types of malaria infection, it takes a long time for symptoms to appear, and the disease only breaks out after several days, weeks, or even months after you have returned home from your stay abroad.

Seek medical attention immediately if you experience symptoms such as fever, headache, chills, and fatigue after returning home.

What you need to know before using Malastad

Do not use Malastad

  • if you are allergic ( hypersensitive ) to atovaquone, proguanil hydrochloride or any of the other ingredients of this medicine (listed in section 6)
  • As a prophylaxis (prevention) against malaria if you have a serious kidney disease.

Warnings and cautions

Talk to a doctor or pharmacist before taking Malastad.

Malaria prevention

  • if you are sick (vomiting) within an hour after taking the tablet, take a new dose immediately
  • it is important that you complete the prescription one of Malastad. If you have to take additional tablets due to vomiting, you may need to get more Malastad prescribed
  • if you have vomited, it is especially important to use other protective measures such as insecticides and mosquito nets. The effect of Malastad can be reduced because the amount of drugs taken up in the body then becomes smaller.

Treatment of malaria

  • If you experience vomiting and diarrhea, consult your doctor as regular blood tests should be taken. The effect of Malastad decreases because the amount of drug taken up in the body then becomes smaller. Blood samples are taken to show if the malaria parasite has disappeared from the blood
  • If you have severe kidney disease, your doctor may decide to prescribe another medicine
  • if you get a certain type of infection during treatment with Malastad, your doctor may prescribe another type of medicine instead of Malastad
  • for malaria treatment, but then comes back repeatedly or if malaria is caused by a certain type of parasite, your doctor may decide that a different drug is taken simultaneously with Mala City.

Other medicines and Malastad

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Some medicines can affect the effect of Malastad and Malastad can also increase or decrease the effect of other medicines taken at the same time, eg:

  • antibiotics , tetracyclines , rifampicin and rifabutin
  • efavirenz or some very active protease inhibitors (used to treat HIV )
  • warfarin and other blood thinners
