Q: How should I take Chloroquine?
A: A patient can take Chloroquine in parasitic infections like malaria and amoebic liver disorders and certain conditions involving the immune system. There are four different types of malaria, though only two are more common; the dosage and duration may change for each type. Hence Chloroquine has to be taken under medical supervision to avoid irregular usage. The dosage of this medicine in immune disorders such as Systemic Lupus Erythematosus and Rheumatoid Arthritis also differs based on the severity of the disease. Improper administration may cause unwanted effects and hence self-medication with Chloroquine is not advised.
Q: How does Chloroquine act against blood parasites and the immune system?
A: Chloroquine can penetrate the parasites present in the blood (malaria) and the liver (Amoebiasis). After entering the parasite, it stops the formation of substances that may cause harm to us and thus control the infection. In diseases such as Systemic Lupus Erythematosus (SLE) or Rheumatoid Arthritis (RA) due to improperly regulated immune systems, Chloroquine disrupts the signaling between immune cells. It thus reduces or suppresses the unwanted immune system activity resulting in relief of symptoms. Chloroquine acts in different diseases with different mechanisms.
