What is Chloroquine?

Chloroquine is a prescription medication that helps treat or prevent malaria, a disease caused by a parasite that enters the system through a mosquito bite. This medicine is not effective against all the malaria strains. It is also not of much use against the parasite in the areas where the infection has become resistant to it or a similar drug known as hydroxychloroquine. This medicine is readily available, and you can easily buy Chloroquine online if you have a doctor’s prescription. 


Doctors primarily prescribe this drug to treat malaria. This drug can also help prevent malaria if you take it before going to a high infection rate area, as prescribed by your doctor. Doctors often prescribe this drug to treat amebiasis, which is an infectious disease caused by amoebae. 

This medicine works by attacking the parasite. It interferes with its essential processes. The malaria parasite metabolizes hemoglobin present in the red blood cells to survive, and this process produces a toxic and soluble molecule heme. The parasite crystalizes it to form hemozoin to avoid destruction by heme. Chloroquine diffuses into red blood cells and prevents the parasite from converting heme into hemozoin, which increases the toxicity and eventually kills the parasite.

How to take Chloroquine?

Try using this medicine as prescribed by your doctor. Make sure to follow the prescription label or the medication guide you get when you order Chloroquine online or purchase it from the local drugstore. Avoid consuming more than the prescribed amount and using it for more than the recommended period.

For preventing malaria, doctors typically recommend taking this drug once per week on the same day each week. Begin using this medicine at least two weeks before going to the area where malaria is common. Keep consuming this drug for your entire stay. You also have to continue the treatment for at least eight weeks after leaving the area.

For treating malaria, doctors prescribe one high dose of Chloroquine, followed by smaller amounts for the next two days. 

Your doctor might recommend higher doses for two days for treating amebiasis, followed by smaller quantities for two to three weeks. The doctor might also prescribe another medication to help prevent further infection.

Chloroquine doses usually correspond to the body weight, so your doctor might change the prescribed amount if you gain or lose weight during the treatment period.
