What is Chloroquine used for?Chloroquine phosphate is prescribed for the prevention and treatment of malaria caused by mosquito bites. Malaria parasites enter the body through mosquito bites in countries where malaria is common. The parasites then live in body tissues such as the liver or red blood cells. Chloroquine works to kill the malaria parasites living within the red blood cells. If you have malaria parasites living in other bodily tissues you will be prescribed an additional medication to kill those parasites. Both medications may be needed to completely cure malaria and prevent relapse. Chloroquine is part of a drug class called antimalarials. The United States Centers for Disease Control give frequently updated travel recommendations and guidelines for the malaria prevention and treatment in different parts of the world. Talk with your doctor about this before travelling to parts of the world where malaria occurs. Chloroquine can be used to treat other conditions such as infections caused by ameba, or lupus erythematosus. Talk to your doctor about these uses of Chloroquine to see if it is a good fit for your treatment.
How to Use Chloroquine?
Always take your medications exactly as your doctor prescribes. Do not change how frequently you take Chloroquine or how much medication you take without first consulting your doctor. This is a description of the typical dosing and use instructions and not in any way medical advice.
Take Chloroquine with meals or a glass of milk to lessen stomach upset, unless your doctor tells you otherwise.
If you take Chloroquine to prevent malaria:
- Your doctor will ask you to start treatment with chloroquine 1-2 weeks before travelling to an area where malaria can be contracted through mosquito bites. This will help to see how you react to Chloroquine. It also allows time for your doctor to change your treatment if you react to Chloroquine.
- You should keep taking Chloroquine while you’re in the area and for 4 weeks after leaving. No medication will completely protect you from malaria. However, to be as protected as is possible, it’s important to keep taking Chloroquine for the full time your doctor has prescribed. If fever develops during your travel or within 2 months of leaving the area, check in with your doctor immediately.
If you take this medication to protect you from getting malaria, take it for the full time it’s prescribed. If you have malaria, you should keep taking Chloroquine for the fully prescribed time, even if you start to feel better after a few days. This will help to clear your infection completely. If you stop Chloroquine too early your symptoms may return.
To get the best results take Chloroquine on a regular schedule. Take it at the same time of day at the frequency it’s prescribed. Do not skip any doses.
If you also take antacids or kaolin take them at least 4 hours before or after you take Chloroquine. If you take ampicillin take it 2 hours before or after using Chloroquine.
