Using this medicine while you are pregnant can harm your unborn baby.

If you think you have become pregnant while using this medicine, tell your doctor right away.

Before taking this medicine, you and your child should be tested for G6PD deficiency or favism (blood disorder). Tafenoquine may cause hemolytic anemia in patients with these conditions. Talk to your doctor if you have concerns about this.

This medicine may cause some people to be agitated, irritable, or display other abnormal behaviors. Make sure the doctor knows if you have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. Also tell the doctor if you have sudden or strong feelings, such as feeling nervous, angry, restless, violent, or scared. If you or your caregiver notice any of these side effects, tell your doctor right away.

This medicine may cause a serious allergic reaction, including angioedema, which can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or large, hive-like swelling on face, eyelids, lips, tongue, throat, hands, legs, feet, or genitals.

Malaria is spread by the bites of certain kinds of infected female mosquitoes. If you are living in or will be traveling to an area where there is a chance of getting malaria, the following mosquito-control measures will help to prevent infection:

  • If possible, avoid going out between dusk and dawn because it is at these times that mosquitoes most commonly bite.
  • Remain in air-conditioned or well-screened rooms to reduce contact with mosquitoes.
  • Wear long-sleeved shirts or blouses and long trousers to protect your arms and legs, especially from dusk through dawn when mosquitoes are out.
  • Apply insect repellant, preferably one containing DEET, to uncovered areas of the skin from dusk through dawn when mosquitoes are out.
  • If possible, sleep in a screened or air-conditioned room or under mosquito netting, preferably coated or soaked with pyrethrum, to avoid being bitten by malaria-carrying mosquitoes.
  • Use mosquito coils or sprays to kill mosquitoes in living and sleeping quarters during evening and nighttime hours.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
