Key points

  • Chloroquine kills the organisms that cause malaria and amebiasis, placing it in the Antiparasitics class.
  • It can cause serious vision problems; stop taking it and get urgent medical help if you notice changes in your vision.
  • The brand name Aralen is no longer on the market, so Chloroquine Tablets is the generic form available here.

What to watch for

Chloroquine can affect the heart rhythm, and irregular heartbeats, dizziness or fainting while taking it need urgent medical help. Children are especially sensitive to a chloroquine overdose, so keep the tablets out of their reach. If you are breastfeeding, chloroquine can harm a nursing infant. For long-term use, regular eye exams matter because of the vision risk.
