What is Primaquine 15 mg?
Primaquine 15 mg is an antimalarial medication manufactured by HAB Pharmaceuticals & Research Ltd. It contains the active ingredient Primaquine and is primarily used to prevent and treat malaria, a mosquito-borne infectious disease. This medicine plays a crucial role in eliminating the dormant forms of malaria parasites in the liver, preventing relapse and progression of the disease. Available in tablet form, Primaquine 15 mg is carefully formulated to meet medical standards applicable in Australia and worldwide.
Uses of Primaquine 15 mg
Primaquine 15 mg is prescribed mainly for:
- Treatment of Malaria, particularly the elimination of liver-stage parasites (hypnozoites) that may cause relapse in infections caused by Plasmodium vivax and Plasmodium ovale.
- Prophylaxis against malaria for travelers heading to regions with high malaria transmission.
- Adjunct therapy to prevent the spread and reinfection by targeting the gametocyte stage of Plasmodium falciparum in combination treatments.
How Primaquine 15 mg Works
Primaquine 15 mg works by targeting the malaria parasites residing in the liver and blood. Unlike other antimalarial drugs that mainly act on the blood stages, Primaquine uniquely eradicates dormant liver forms called hypnozoites, which can reactivate causing malaria relapses. It disrupts the parasites’ metabolism leading to their death, reducing the risk of re-emergence of infection. This dual action makes Primaquine essential for radical cure of certain types of malaria.
Benefits of Primaquine 15 mg
- Effective Radical Cure: Clears dormant liver parasites, preventing relapse.
- Reduces Transmission: Destroys gametocytes to reduce malaria spread.
- Convenient Dosage: Available in 15 mg tablets for flexible dosing.

- Supports Malaria Control Programs: Helps to combat malaria in endemic regions.
Dosage and Administration
Primaquine 15 mg should be taken as prescribed by a healthcare professional. Typical adult dosage for radical cure usually involves a daily dose taken orally for 14 days. For malaria prophylaxis, dosing regimens may differ and can include weekly administration. It is important to take the tablets with food to reduce stomach upset and to complete the full course even if symptoms improve. Dosage may vary based on individual patient condition, age, and weight.
