Drug pricing is set separately in each country through different negotiation, regulatory, and distribution systems, so the same medication can legitimately carry different price tags on either side of the border. In this case, our data shows the Canadian price coming in lower — but that isn't true for every drug, so it's worth checking each medication individually rather than assuming.

While chloroquine is widely available as a generic drug, it is also marketed under specific brand names. The primary brand-name versions are Aralen Phosphate and Aralen Hydrochloride. These products are manufactured by several pharmaceutical companies.

Chloroquine is an antimalarial drug used to prevent and treat malaria infections acquired from mosquito bites in endemic areas. It works by targeting the malaria parasites during their blood-stage lifecycle inside red blood cells. The drug interferes with the parasite's ability to detoxify heme, a byproduct of digesting hemoglobin, leading to a toxic buildup that kills the parasite. For a complete cure, especially for certain types of malaria, a second medication like primaquine may be required to eliminate parasites dormant in the liver. Chloroquine is also effective in treating amebiasis by killing the causative amoebic parasites in the intestines.

Common side effects of chloroquine can include gastrointestinal issues like diarrhea, vomiting, and stomach cramps, as well as headache, temporary hair loss, mild muscle weakness, and changes in skin or hair color. This is not a complete list of all possible adverse reactions. Patients should discuss any concerns or new symptoms with their healthcare provider. Serious side effects can be reported to the U.S. Food and Drug Administration (FDA).
