Primaquine Tablets are an antimalarial medication primarily used to treat and prevent malaria caused by specific parasites.

Here are the key details:

• Main Uses:

  • Treatment of Plasmodium vivax and Plasmodium ovale infections by targeting the dormant liver stages that can cause relapses.

  • Sometimes used as malaria prophylaxis for travelers to malaria-endemic regions.

  • Helps prevent the spread of malaria by acting against the sexual forms of the parasite (gametocytes).

• How It Works:

  • Primaquine kills malaria parasites in the liver and prevents them from multiplying.

  • Effective against both the liver stage and the gametocytes, reducing the risk of recurrence and transmission.

• Administration:

  • Taken orally, usually once daily for the duration prescribed by a doctor.

  • Dose is determined based on body weight, age, and type of malaria.

  • Best taken with food to reduce stomach upset.

• Common Side Effects:

  • Nausea, vomiting, stomach discomfort.

  • Dizziness or mild headache.

  • Occasional mild skin rash.

• Serious Concerns:

  • Can cause hemolytic anemia in people with G6PD deficiency, a genetic enzyme disorder.

  • Rarely may lead to methemoglobinemia, affecting oxygen delivery in the blood.

  • Severe allergic reactions are rare but possible.

• Precautions:

  • G6PD testing is recommended before starting therapy to prevent serious complications.

  • Use with caution during pregnancy, especially in G6PD-deficient individuals.

  • Monitor for signs of anemia such as fatigue, pale skin, or shortness of breath.

  • Inform the doctor about other medications and existing health conditions.

• Storage: Store at room temperature, away from moisture, heat, and direct sunlight.

👉 Primaquine Tablets are effective for eliminating dormant malaria parasites and preventing relapses, but require careful screening for G6PD deficiency and monitoring for side effects.
