primalex (PRIMAQUINE)
What is Primalex?
Primalex is an antimalarial medication used to treat malaria caused by the Plasmodium vivax and Plasmodium ovale parasites. It is also used to prevent malaria relapse by targeting the liver stages of the parasite. It works by disrupting the parasite's ability to multiply in the liver, reducing the chances of malaria reoccurring.
What is the usual dose of Primalex?
For malaria prevention, the typical dose is 30 mg of Primalex once daily for 14 days after travel to endemic areas. For relapse prevention, the dose may vary from 15 to 30 mg daily, depending on the severity of the condition. Always follow the doctor’s prescribed dosage for specific needs.
How do I take Primalex?
Primalex should be taken with food to reduce the risk of stomach upset. Swallow the tablets whole without crushing or chewing. The exact duration of treatment will depend on your doctor's recommendation, but it's usually a short-term regimen. Stick to the prescribed schedule, even if you feel better, to ensure effective treatment.
For how long do I take Primalex?
For relapse prevention and malaria treatment, the usual course of Primalex is between 7 to 14 days. The treatment duration depends on the nature of the malaria infection, and it’s essential to complete the full course as prescribed to prevent relapse and ensure complete parasite elimination.
What disease or symptom is Primalex used for?

How long does it take for Primalex to start working?

Is Primalex effective?
Primalex is highly effective for relapse prevention in P. vivax and P. ovale malaria. It works by targeting the liver stages of the parasite, which are often responsible for relapses.

How does Primalex work?
