Tafenoquine (Krintafel) is used to prevent the return of malaria (a serious infection that is spread by mosquitoes in certain parts of the world and can cause death) in people that are infected and are currently receiving another medication to treat malaria. Tafenoquine (Arakoda) is used alone to prevent malaria in travelers who visit areas where malaria is common. Tafenoquine is in a class of medications called antimalarials. It works by killing the organisms that cause malaria.
Tafenoquine comes as tablets to take by mouth with food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take tafenoquine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
If you are taking tafenoquine (Krintafel) to prevent malaria from coming back, it is usually taken as a single dose (2 tablets).
If you are taking tafenoquine (Arakoda) for the prevention of malaria, one dose (2 tablets) is usually taken once a day for 3 days, starting 3 days before traveling to an area where there is malaria. While you are in the area, one dose (2 tablets) is usually taken once a week on the same day of the week. After you return from the area, one dose (2 tablets) is usually taken 7 days after the last dose that was taken before your return. You should not take tafenoquine (Arakoda) for the prevention of malaria for more than 6 months.
Swallow the tablets whole; do not split, chew, or crush them.
If you vomit within an hour after taking tafenoquine (Krintafel), call your doctor. You may need to take another dose of this medication.
Take tafenoquine until you finish the prescription, even if you feel better. If you stop taking tafenoquine too soon or skip doses, your infection may not be completely treated or you may not be protected from future infections.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient if you are taking Tafenoquine (Krintafel).

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site
