Compare Hsquin (Hydroxychloroquine) with Alternatives for Autoimmune and Inflammatory Conditions

Hydroxychloroquine - sold under the brand name Hsquin - was once widely used for malaria and later became a go-to drug for autoimmune conditions like lupus and rheumatoid arthritis. But after years of controversy, shifting guidelines, and new research, many patients and doctors are asking: Are there better options? If you’re on Hsquin or considering it, you deserve to know what else is out there - and what actually works today.

What Hsquin (hydroxychloroquine) actually does

Hydroxychloroquine is an antimalarial drug that also has immune-modulating effects. It doesn’t cure autoimmune diseases, but it helps calm overactive immune responses. For people with systemic lupus erythematosus (SLE), it reduces skin rashes, joint pain, and fatigue. In rheumatoid arthritis, it slows joint damage and lowers flare frequency. It’s often used long-term because it’s generally well-tolerated and doesn’t suppress the immune system as hard as steroids or biologics.

But here’s the catch: it’s not magic. Studies show only about 40-60% of lupus patients respond well to hydroxychloroquine alone. And it takes weeks - sometimes months - to see results. That’s why many doctors pair it with other drugs, or switch entirely if side effects show up.

Common side effects of Hsquin

Most people tolerate hydroxychloroquine fine. But side effects can be serious - and they don’t always show up right away.

• Eye damage (retinopathy): Risk increases after 5+ years of use. Requires annual eye exams.
• Stomach upset: Nausea, diarrhea, cramps - common early on.
• Headaches and dizziness.
• Low blood sugar: Especially risky for diabetics.
• Heart rhythm issues: Rare, but dangerous. Can cause QT prolongation, especially with other drugs.

The FDA issued a warning in 2020 about heart risks when combined with azithromycin - a combo that briefly gained attention during the pandemic. Even without that, long-term use demands monitoring. If you’re on Hsquin, you should have an eye exam every year and an ECG if you have heart disease or take other QT-prolonging meds.

Alternative 1: Chloroquine

Chloroquine is hydroxychloroquine’s older cousin. It works similarly but is stronger and more toxic. It’s rarely used today for autoimmune conditions because it carries a higher risk of retinal damage - up to twice as much as hydroxychloroquine.

Chloroquine is still used in some parts of the world for malaria, but for lupus or arthritis, it’s not the first choice anymore. If your doctor suggests it, ask why. In most cases, hydroxychloroquine is safer and just as effective.

Alternative 2: Sulfasalazine

Sulfasalazine is an old-school drug originally developed for ulcerative colitis. It’s now commonly used for rheumatoid arthritis and sometimes for lupus-related joint pain. It works by reducing inflammation in the gut and joints.

Pros:

• Lower risk of eye damage
• Good for patients with both arthritis and inflammatory bowel disease
• Cost-effective

Cons:

• Can cause nausea, headaches, and low sperm count in men
• Turns urine and tears orange - which freaks people out at first
• Slower to work than hydroxychloroquine

It’s not a direct replacement for Hsquin, but for patients who can’t tolerate eye monitoring or need gut-targeted therapy, sulfasalazine is a solid backup.

Alternative 3: Methotrexate

Methotrexate is the most common disease-modifying antirheumatic drug (DMARD) used for rheumatoid arthritis. It’s stronger than hydroxychloroquine and works faster - often within 6-8 weeks.

For lupus patients, methotrexate is used when skin or joint symptoms don’t respond to hydroxychloroquine alone. It’s also used in combination with Hsquin for better control.

Pros:

• Proven to prevent joint damage
• Works well with hydroxychloroquine
• Available as a weekly pill or injection

Cons:

• Requires monthly blood tests (liver and kidney function)
• Can cause mouth sores, fatigue, and hair thinning
• Not safe during pregnancy
• Must take folic acid daily to reduce side effects

Methotrexate isn’t for everyone, but for moderate to severe arthritis or lupus with organ involvement, it’s often the next step after hydroxychloroquine.

Alternative 4: Leflunomide

Leflunomide is another DMARD used for rheumatoid arthritis. It blocks immune cells that cause joint inflammation. It’s less commonly used for lupus but can be helpful when methotrexate fails or isn’t tolerated.

Pros:

• Once-daily pill
• Effective for joint swelling and pain
• Can be used if methotrexate causes liver issues

Cons:

• High risk of liver toxicity
• Can cause diarrhea, high blood pressure, and hair loss
• Stays in the body for months - requires a special washout if you need to stop it

Leflunomide is a good option if you’ve tried hydroxychloroquine and methotrexate and still have active disease. But it’s not a first-line replacement - more of a second or third choice.

Alternative 5: Biologics (like belimumab or rituximab)

For lupus patients who don’t respond to traditional drugs, biologics are the next level. Belimumab (Benlysta) is the only FDA-approved biologic specifically for lupus. It targets B-cells that drive autoimmune attacks.

It’s given as a monthly IV infusion or weekly injection. Studies show it reduces flares by about 30% and lowers steroid use.

Rituximab (Rituxan) isn’t officially approved for lupus but is used off-label for severe cases - especially kidney or neurological involvement.

Pros:

• Targets the root cause of lupus, not just symptoms
• Can induce remission in resistant cases
• Lower long-term steroid use

Cons:

• Expensive - often over $20,000 per year
• Requires IV infusions or injections
• Higher infection risk
• Not always covered by insurance without trial of other drugs first

Biologics aren’t replacements for Hsquin - they’re for when Hsquin isn’t enough. Most patients try hydroxychloroquine, then methotrexate, then biologics.

When to consider stopping Hsquin

You shouldn’t quit Hsquin on your own. But if you’re experiencing:

• Vision changes (blurriness, light sensitivity, blind spots)
• Unexplained heart palpitations or dizziness
• Severe nausea or skin rashes
• Low blood sugar you can’t explain

…then talk to your doctor. You might need a switch. Some patients stop because of cost - Hsquin can be expensive without insurance. Others stop because they feel fine and think they don’t need it anymore. That’s risky. Stopping suddenly can trigger a flare.

What most doctors recommend today

In 2025, the standard approach is:

1. Start with hydroxychloroquine for mild lupus or arthritis.
2. Get annual eye exams - don’t skip them.
3. If symptoms persist after 3-6 months, add methotrexate or switch to sulfasalazine.
4. If you still have flares or organ damage, move to biologics like belimumab.
5. Avoid chloroquine unless there’s no other option.

There’s no one-size-fits-all. Your choice depends on your symptoms, other health conditions, cost, and how well you tolerate side effects.

Real patient stories

Anna, 52, from Durban, was on Hsquin for 7 years for lupus. Her vision started blurring. Her eye doctor caught early retinopathy. She switched to methotrexate and now takes folic acid daily. Her joints still ache, but her eyes are stable.

James, 38, had rheumatoid arthritis. Hsquin helped a little, but he still couldn’t grip his tools. His doctor added sulfasalazine. The orange urine freaked him out at first - but within 3 months, he could lift his kids again.

These aren’t rare cases. They’re routine.

Bottom line

Hsquin isn’t bad - it’s just not always enough. For many, it’s a helpful first step. But if it’s not working, or if you’re worried about side effects, there are real, proven alternatives. The key is not to stay stuck on one drug. Autoimmune diseases change. Your treatment should too.

Don’t be afraid to ask your doctor: "Is Hsquin still the best option for me?" If they don’t have a clear answer, get a second opinion. Your health isn’t a one-drug solution.
