What is hydroxychloroquine tablets used for?

Hydroxychloroquine tablet, often shortened to HCQ, have been a subject of much discussion, particularly during the COVID-19 pandemic. However, its primary uses lie in treating and preventing other well-established medical conditions. Here’s a comprehensive look at the established uses of hydroxychloroquine tablets:

1. Malaria: A Powerful Weapon Against a Debilitating Disease

Fighting the Parasite: Hydroxychloroquine is a medication used to prevent and treat malaria, a mosquito-borne parasitic infection. It works by eliminating the malaria parasite in the bloodstream, preventing its further development and spread within the body.
Preventive and Treatment Applications: HCQ can be taken as a short-term preventive measure for travelers visiting regions with a high risk of malaria. It can also be used as a treatment for confirmed malaria cases.
Resistance Concerns: The overuse of hydroxychloroquine for malaria treatment has led to concerns about parasite resistance. Responsible use and alternative treatment options are crucial for maintaining its effectiveness against malaria.
2. Autoimmune Diseases: Modulating the Immune System

Taming the Overactive Response: Hydroxychloroquine is used to treat certain autoimmune diseases, such as lupus (systemic lupus erythematosus) and rheumatoid arthritis. These conditions involve an overactive immune system that attacks healthy tissues.
Managing Symptoms and Disease Progression: HCQ helps modulate the immune system, reducing inflammation, pain, swelling, and joint stiffness associated with these autoimmune diseases. It can improve quality of life and slow disease progression.
3. Other Potential Uses: Still Under Investigation

Beyond Established Applications: Research is ongoing to explore the potential use of hydroxychloroquine for other conditions, such as certain skin diseases and some complications of COVID-19. However, more research is needed to confirm its efficacy and safety in these contexts.
Important Considerations:

Prescription Medication: Hydroxychloroquine is a prescription medication and should only be taken under the supervision of a doctor.
Potential Side Effects: Like any medication, HCQ can cause side effects, including nausea, vomiting, diarrhea, and abdominal pain. In rare cases, it can have more serious side effects like eye damage. Regular eye exams are recommended while taking HCQ.
Drug Interactions: Hydroxychloroquine can interact with other medications. It’s crucial to disclose your complete medication list to your doctor before starting HCQ therapy.
Hydroxychloroquine and COVID-19: Separating Fact from Fiction

While initial studies explored the potential use of hydroxychloroquine for COVID-19 treatment, large-scale clinical trials haven’t shown conclusive evidence of its effectiveness. Currently, it is not recommended as a standard treatment for COVID-19.


Hydroxychloroquine tablets are a valuable medication with established uses in preventing and treating malaria and managing autoimmune diseases. However, it’s crucial to understand its appropriate applications, potential side effects, and the importance of consulting a doctor for diagnosis and treatment. For COVID-19, alternative treatment options based on current medical guidelines are recommended.
