Hydroxychloroquine is a medication that has gained widespread attention in recent years, largely due to its controversial role in treating COVID-19. However, this medication has a rich history and a variety of uses that extend far beyond the pandemic. Known primarily as an antimalarial drug, hydroxychloroquine has proven effective in managing a range of diseases, particularly autoimmune conditions. In this blog, we’ll dive deep into the uses of hydroxychloroquine, its history, how it works, and the benefits and risks associated with it. By the end of this post, you’ll have a clear understanding of the diverse applications of hydroxychloroquine and why it’s such a valuable medication in modern medicine.
What is Hydroxychloroquine?
Hydroxychloroquine, sold under brand names like Plaquenil, is a medication first developed in 1955. It belongs to a class of drugs known as disease-modifying antirheumatic drugs (DMARDs), which help in treating diseases by altering the underlying conditions rather than merely relieving symptoms.

Originally synthesized as a less toxic derivative of chloroquine (another antimalarial drug), hydroxychloroquine has since been used to treat several conditions.
Hydroxychloroquine works by reducing inflammation in the body and modulating the immune system, making it beneficial for both infection-related conditions and autoimmune diseases. Its effectiveness in regulating the immune response is what makes it such a versatile medication.
The Primary Uses of Hydroxychloroquine
1. Treatment and Prevention of Malaria
The original and still one of the primary uses of hydroxychloroquine is for the treatment and prevention of malaria. Malaria is a mosquito-borne disease caused by parasites that infect red blood cells, leading to high fever, chills, and flu-like symptoms. Hydroxychloroquine interferes with the growth of these parasites in the blood, making it effective in both treating active malaria infections and preventing the disease when traveling to regions where malaria is prevalent.
However, it’s important to note that malaria-causing parasites have developed resistance to hydroxychloroquine in some parts of the world, particularly in Southeast Asia and Africa. As a result, other medications may be preferred in these regions. Still, hydroxychloroquine remains a valuable option in areas where resistance has not developed.
2. Rheumatoid Arthritis (RA)
Rheumatoid arthritis is an autoimmune disorder where the body’s immune system mistakenly attacks healthy joint tissue, causing inflammation, pain, and eventual joint damage. Hydroxychloroquine is often prescribed for patients with mild to moderate rheumatoid arthritis because of its ability to reduce inflammation and slow down the progression of the disease.
The drug doesn’t work immediately—it may take several weeks or months for patients to experience the full benefits. However, once it starts working, hydroxychloroquine can significantly improve quality of life by reducing pain and stiffness, allowing patients to maintain mobility and prevent further joint deterioration.
3. Systemic Lupus Erythematosus (SLE)
Systemic lupus erythematosus, commonly known as lupus, is another autoimmune disease where the immune system attacks its own tissues, leading to inflammation and damage in organs such as the skin, joints, kidneys, and heart. Lupus is a complex disease that can vary greatly in severity from person to person, and managing its symptoms often requires a combination of medications.
Hydroxychloroquine is one of the cornerstone treatments for lupus due to its immunomodulatory effects. It helps reduce inflammation, skin rashes, joint pain, and the risk of lupus flares. Perhaps most importantly, studies have shown that lupus patients who take hydroxychloroquine long-term have lower mortality rates compared to those who don’t. It can even help prevent the formation of blood clots, a common complication in lupus patients.
4. Juvenile Idiopathic Arthritis (JIA)
Juvenile idiopathic arthritis is a type of arthritis that affects children under the age of 16. Like rheumatoid arthritis, it causes joint pain, swelling, and stiffness. Hydroxychloroquine can be prescribed as part of the treatment plan for JIA, especially when other medications like NSAIDs (non-steroidal anti-inflammatory drugs) do not provide sufficient relief. Its role in controlling inflammation makes it an important treatment option for children dealing with this chronic condition.
5. Discoid Lupus Erythematosus
Discoid lupus is a form of lupus that primarily affects the skin. It causes round, red, scaly patches on the face, scalp, and other parts of the body, which can lead to scarring if untreated. Although it does not affect internal organs like systemic lupus, the impact of discoid lupus on a person’s appearance and self-esteem can be significant. Hydroxychloroquine is commonly prescribed for discoid lupus because it helps reduce skin inflammation and prevents the condition from progressing to systemic lupus in some cases.
How Hydroxychloroquine Works
Understanding how hydroxychloroquine works can provide insight into why it’s used to treat such a diverse array of conditions. The drug alters the immune system by affecting how immune cells function. For instance, it inhibits certain pathways that lead to inflammation, which is crucial in autoimmune diseases where the immune system mistakenly targets healthy tissues.
Hydroxychloroquine also increases the pH inside cells, which interferes with the ability of certain parasites (like those that cause malaria) to survive and replicate. This combination of immune-modulating and antiparasitic properties makes it a valuable drug in both infection and autoimmune diseases.
The Controversy: Hydroxychloroquine and COVID-19
Hydroxychloroquine became a household name in 2020 during the COVID-19 pandemic. Initially, there was a lot of excitement surrounding the drug after some early studies suggested that it might help treat COVID-19. As the pandemic progressed, hydroxychloroquine was touted by some as a potential cure or preventive measure for the virus.
However, as more research was conducted, it became clear that hydroxychloroquine was not as effective as initially hoped in treating COVID-19. Large clinical trials found little to no benefit in reducing the severity or duration of the disease. Furthermore, the use of hydroxychloroquine without proper medical supervision was found to cause serious side effects in some patients, including heart problems. As a result, many health authorities, including the World Health Organization (WHO) and the U.S. Food and Drug Administration (FDA), cautioned against its use for COVID-19 outside of clinical trials.
While hydroxychloroquine is no longer considered a viable treatment for COVID-19, the controversy surrounding its use highlighted the importance of rigorous scientific research before endorsing a medication for new uses.
Potential Side Effects and Risks
Like any medication, hydroxychloroquine is not without its side effects. Most people tolerate the drug well, but some may experience adverse effects, particularly with long-term use. Common side effects include:
- Nausea and vomiting
- Headaches
- Dizziness
- Stomach cramps
More serious but less common side effects include vision problems due to retinal damage, muscle weakness, and heart rhythm issues. Regular monitoring by a healthcare provider, including eye exams, is recommended for patients on long-term hydroxychloroquine therapy to catch any potential complications early.
Conclusion: Hydroxychloroquine’s Versatility in Medicine
Hydroxychloroquine is a medication that has stood the test of time. Initially developed for malaria, it has found a home in the treatment of a variety of autoimmune diseases like rheumatoid arthritis and lupus, where its anti-inflammatory and immune-modulating properties have made it indispensable. While its role in COVID-19 treatment was ultimately debunked, its uses in other conditions remain invaluable to millions of patients worldwide.
