Avloclor 250mg Tablets contain chloroquine, a medicine used to prevent and treat malaria, a serious disease caused by parasites transmitted through mosquito bites. Chloroquine works by interfering with the growth and reproduction of the malaria parasites in the red blood cells, helping to stop the infection from developing or worsening.

It is commonly taken before, during, and after travel to malaria-risk areas as prescribed, and may also be used to treat certain other parasitic infections or autoimmune conditions like lupus. The tablets should be taken exactly as directed to ensure effective protection and reduce the risk of side effects.
