Hydroxychloroquine tablet (HCQ) has been in the spotlight for the past few years, particularly during the COVID-19 pandemic. While research into its effectiveness against COVID-19 hasn’t yielded positive results, hydroxychloroquine remains a well-established medication with proven benefits for several conditions

Established Benefits:

  • Malaria Prevention and Treatment: HCQ is a mainstay medication for preventing and treating malaria, a potentially life-threatening parasitic infection. It works by interfering with the parasite’s life cycle within the red blood cells. You can also try ivermectin 6 mg tablet to treat infections

  • Autoimmune Diseases: HCQ is a disease-modifying antirheumatic drug (DMARD) used to manage chronic autoimmune diseases like lupus and rheumatoid arthritis. It helps regulate the overactive immune system responsible for attacking healthy tissues. Here’s a story about Sarah’s experience:

    • Sarah’s Story: Diagnosed with lupus at a young age, Sarah battled fatigue, joint pain, and skin rashes. Traditional treatments offered some relief, but the flare-ups were debilitating. Her doctor introduced HCQ, and slowly, Sarah noticed a difference. The flares became less frequent and less severe. “HCQ isn’t a cure,” she says, “but it’s given me back control of my life.”

  • Other Potential Uses: Research is ongoing to explore HCQ’s potential benefits for other conditions, including:

    • Porphyria: A group of inherited disorders affecting the nervous system and skin.

    • Certain cancers: Studies suggest HCQ might have anti-cancer properties.

Important Considerations:

  • Side Effects: While generally well-tolerated, HCQ can cause side effects like nausea, diarrhea, and abdominal cramps. In rare cases, it can lead to serious eye problems. Regular eye exams are crucial during HCQ treatment.

  • Drug Interactions: HCQ can interact with other medications, so it’s important to disclose all medications you’re taking to your doctor.

  • Dosage and Monitoring: The appropriate dosage of HCQ varies depending on the condition being treated. Regular doctor visits are essential to monitor progress and potential side effects.

Historical Context:

  • HCQ’s story stretches back to the 1930s when it was developed as a treatment for malaria. Its effectiveness and relatively mild side effects compared to other antimalarial medications led to its widespread use.

  • In the 1950s, its benefits for managing lupus were discovered by accident. A doctor noticed a patient with both lupus and malaria improved significantly on HCQ for malaria, leading to further research on its impact on lupus symptoms.

Mechanism of Action:

  • The exact way HCQ works in autoimmune diseases is still under investigation. However, it’s believed to suppress the overactivity of the immune system, thereby reducing inflammation and tissue damage.

Treatment Regimen:

  • HCQ is typically taken as a daily pill, though the exact dosage depends on the condition being treated and the patient’s individual needs.

Safer Alternatives for Some:

  • For pregnant or breastfeeding women with lupus, other medications might be a safer alternative to HCQ due to potential risks to the developing baby. It’s crucial to discuss all options with a healthcare professional.

The Future of HCQ Research:

  • Ongoing research is exploring HCQ’s potential benefits for various conditions, including:

    • Neurodegenerative diseases like Alzheimer’s and Parkinson’s

    • Certain inflammatory bowel diseases


Human Stories & Research:

Here are some resources for further exploration:

  • Lupus Foundation: https://www.lupus.org/resources/drug-spotlight-on-hydroxychloroquine provides detailed information on HCQ’s use in lupus, including patient experiences.

  • National Institutes of Health (NIH): https://clinicaltrials.gov/ct2/show/NCT04332991 offers a search engine for clinical trials on HCQ for various conditions.

  • Arthritis Foundation: https://versusarthritis.org/about-arthritis/treatments/drugs/hydroxychloroquine/ provides information on HCQ’s use in rheumatoid arthritis, including patient stories.



Hydroxychloroquine is a valuable medication with established benefits for malaria prevention and treatment, as well as the management of autoimmune diseases like lupus and rheumatoid arthritis. While research into its effectiveness for other conditions continues, it’s important to remember that it should only be used under the supervision of a doctor and with careful monitoring for potential side effects.
