Which statement about Chloroquine (Aralen) is correct?

Chloroquine (Aralen) is generally considered safe in pregnancy, which makes the selected answer correct. This antimalarial medication has been widely used to treat malaria and certain autoimmune conditions, and its use during pregnancy has been evaluated in various studies. Recommendations often indicate that chloroquine can be administered to pregnant women when there are no safer alternatives, particularly in areas where malaria is endemic. The benefits of treating malaria during pregnancy, which can pose significant risks to both the mother and fetus if untreated, often outweigh potential risks associated with chloroquine.

While the other statements present misinformation about chloroquine, understanding why is important for the context. For instance, chloroquine is not classified as unsafe in pregnancy, thus ruling out that possibility. Additionally, it is not required to be taken daily; the dosing schedule can vary depending on the condition being treated. It's also ineffective against hepatitis C, a viral infection that typically requires different antiviral therapies, thereby confirming that chloroquine is not a suitable treatment option for that condition.
