Malaria is an infection that is transmitted by mosquito bites. Leemether 80mg/480mg Tablet effectively treats malaria by killing the malarial parasites. However, it should not be used to prevent malaria and should be taken only when prescribed by a doctor. This medicine makes you feel better within a few days of treatment. But, if you have fever, chills, muscle pain, or headache soon after you finish your treatment, this could be a sign that you still are infected with malaria. Consult your doctor immediately if you notice any such symptoms.
