Aralen (chloroquine) is a Disease Modifying Anti-Rheumatic Drug (DMARD) that is widely used to reduce inflammation (pain and swelling) in the treatment of many types of arthritis and lupus.
Aralen is also known as a treatment for malaria, a disease caused by a blood-borne parasite that is spread by mosquitoes in many tropical and sub-tropical environments.
Aralen is available as 250 mg oral tablets. The dose is based on lean body weight.
The usual dose ranges from one-half tablet (125 mg) to one tablet (250 mg) per day. The dose should not exceed 3 mg/kg/day of lean body weight.
It can take 8 to 12 weeks for Aralen to start working. It is important for people starting this medication to continue to take it every day. It can take up to 6 months to feel the maximum effect.
Important Tests and Risks
Aralen is generally considered to be safe, but it can very rarely cause issues with the eyes. Patients who take Aralen should have their eyes checked by an eye doctor at least once a year to make sure the medication isn’t affecting the retina at the back of each eye.
