Chloroquine is a medication used to treat both malaria and systemic lupus erythematosus. One side effect is GI upset, and if this occurs the patient may take the medication with food to minimize the symptoms. Chloroquine can also cause retinal damage, so encourage frequent eye exams and tell the patient to immediately report any change in vision.
