Mefloquine Resistance

Mefloquine resistance occurs when malaria parasites evolve and gradually become less affected by the drug mefloquine. This means the medication is less effective at killing the parasites, making it harder to treat the infection. Resistance develops through genetic changes in the parasites, often due to overuse or improper use of the drug. As resistance spreads, alternative treatments are needed, and controlling malaria becomes more challenging. Monitoring resistance helps health officials recommend effective drugs and prevent widespread treatment failures.
