Hydroxychloroquine is a well-known medication that has been in use for decades. Originally developed as an anti-malarial drug, it is now primarily used to treat autoimmune conditions like rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Over the years, its potential benefits, side effects, and safety profile have been closely examined, especially during recent global health events where it gained widespread attention.

In this article, we’ll explore what hydroxychloroquine is, its approved uses, how it works, its benefits, and most importantly—is it safe?
What Is Hydroxychloroquine?
Hydroxychloroquine (brand names: Plaquenil, HCQ) is a disease-modifying antirheumatic drug (DMARD) and belongs to a class of medications known as antimalarials. While it was initially designed to prevent and treat malaria, its anti-inflammatory and immunomodulatory properties made it a mainstay for managing chronic autoimmune diseases.
✅ Approved Medical Uses of Hydroxychloroquine
Hydroxychloroquine is commonly prescribed for:
1. Rheumatoid Arthritis (RA)
It helps reduce joint pain, stiffness, and swelling by calming down an overactive immune response.
2. Systemic Lupus Erythematosus (SLE)
In lupus patients, hydroxychloroquine helps manage flare-ups, reduce fatigue, and protect against organ damage.
3. Malaria Prevention and Treatment
It is used in some parts of the world to prevent or treat malaria, especially strains that are still sensitive to it.
4. Other Off-Label Uses
Doctors may sometimes prescribe HCQ for other autoimmune diseases like Sjogren’s syndrome, dermatomyositis, or COVID-19 (off-label and under strict regulation)—although its effectiveness for COVID-19 is still controversial and not recommended by many health authorities.
How Does Hydroxychloroquine Work?
Hydroxychloroquine works by interfering with the communication between the immune system cells. In autoimmune diseases, the body mistakenly attacks its own tissues. HCQ helps prevent this by:
Reducing immune overactivity
Decreasing inflammation
Protecting against organ damage
Unlike painkillers or steroids that offer immediate relief, hydroxychloroquine takes several weeks to months to show full effects. However, its long-term use can reduce the frequency and severity of disease flares.
Benefits of Hydroxychloroquine
Hydroxychloroquine is widely prescribed because of its unique blend of effectiveness and long-term tolerability. Here are some key benefits:
1. Slows Disease Progression
In conditions like lupus and rheumatoid arthritis, hydroxychloroquine can slow down the progression of joint and organ damage.
2. Reduces Flares
Lupus patients often report fewer and milder flares while on HCQ.
3. Safer Than Other Immunosuppressants
Compared to other DMARDs or steroids, HCQ generally causes fewer serious infections or liver/kidney issues.
4. May Improve Heart Health in Lupus
Some studies suggest HCQ may help protect lupus patients from cardiovascular disease.
5. Compatible with Long-Term Use
Because of its low risk of organ toxicity, HCQ is safe for years of use when monitored correctly.
⚠️ Risks and Side Effects of Hydroxychloroquine
Despite its many benefits, hydroxychloroquine is not free from side effects. Fortunately, most are mild and reversible. However, serious complications, although rare, can occur—especially with long-term use.
✅ Common Side Effects:
Nausea
Stomach cramps
Diarrhea
Dizziness
Headache
Skin rashes
These usually resolve on their own or with dose adjustment.
❌ Less Common but Serious Side Effects:
1. Eye Toxicity (Retinopathy)
The most serious risk is retinal damage, which can lead to vision loss if untreated.
It typically occurs after 5+ years of use or at high doses.
Regular eye exams (every 6-12 months) are essential for early detection.
2. Heart Issues
Rare cases of cardiomyopathy and QT prolongation (irregular heart rhythms) have been reported.
Patients with pre-existing heart conditions should be carefully monitored.
3. Low Blood Sugar
Can cause episodes of hypoglycemia, especially in diabetics.
4. Mood Changes
Some patients report anxiety, mood swings, or vivid dreams, although these are uncommon.
⚕️ Who Should Not Take Hydroxychloroquine?
Hydroxychloroquine is generally safe, but not suitable for everyone. You should not take it without medical supervision if you:
Have pre-existing eye disease (especially retinal issues)
Suffer from heart rhythm disorders
Are allergic to HCQ or similar drugs
Have severe liver or kidney disease
Are pregnant or breastfeeding, unless your doctor determines it’s necessary (HCQ is often safe but used cautiously)
Monitoring and Safety Tips
To safely use hydroxychloroquine, doctors often recommend:
✔️ Baseline and Annual Eye Exams
To monitor for early signs of retinal damage.
✔️ Regular Blood Tests
To check liver function, blood sugar, and kidney health.
✔️ Keep the Dose Within Recommended Limits
The safest dosing is less than 5 mg/kg of body weight per day.
✔️ Inform Your Doctor About All Medications
Avoid combining HCQ with drugs that affect the heart rhythm or lower blood sugar unless advised.
❓ Hydroxychloroquine and COVID-19: What Happened?
During the early days of the COVID-19 pandemic, hydroxychloroquine received attention as a potential treatment. However, clinical trials did not support its effectiveness, and safety concerns—including heart risks—led major health authorities like the FDA, WHO, and CDC to recommend against its use for COVID-19 outside of clinical studies.
Today, its use for COVID-19 is not advised in routine practice.
Key Takeaways
Hydroxychloroquine is generally safe when used under medical guidance for lupus, rheumatoid arthritis, and malaria.
It offers many long-term benefits, especially for autoimmune patients.
However, serious side effects like eye damage and heart problems are possible, particularly with high doses or prolonged use.
Regular monitoring—especially eye exams—is crucial.
It should not be used without a prescription, especially for unapproved conditions like viral infections.
Yes, hydroxychloroquine is safe for most people when taken as prescribed and monitored regularly. It remains one of the most effective treatments for lupus and rheumatoid arthritis, with a better safety profile than many alternatives. Like all medications, it carries risks—but with proper care and follow-up, these can be minimized.
If you’re considering or currently using hydroxychloroquine, speak with your doctor about your individual risk factors, and ensure you follow up with routine testing. When used wisely, HCQ can be a life-changing and life-stabilizing medication.
