Plaquenil (Hydroxychloroquine) Buyer and Patient Handbook in Singapore
What is Plaquenil?
Plaquenil is the brand name for hydroxychloroquine, an antiviral agent supplied as a pill. It is approved by the FDA, EMA and Singapore’s Health Sciences Authority (HSA) for the treatment of Malaria, certain autoimmune disorders and, in specific clinical trials, for viral infections. The tablet is available in 200 mg and 400 mg strengths.
Who Should Use Plaquenil?
- Adults diagnosed with malaria, Systemic [Lupus](link=con:tag:lupus "explore lupus medications") Erythematosus, or Rheumatoid Arthritis.
- Patients enrolled in clinical studies for viral illnesses where hydroxychloroquine is indicated.
- Individuals whose physician has determined that the drug’s benefits outweigh its risks.
How Does It Work?
Hydroxychloroquine interferes with the parasite’s ability to digest hemoglobin and also modulates the immune system, reducing inflammation. In viral contexts, it is thought to raise the pH inside host cells, hindering viral replication. Do not exceed the recommended dose as higher amounts increase the risk of toxicity.
Why Choose Plaquenil?
- Brand reliability: Manufactured under strict GMP standards, ensuring consistent potency.
- Clinical experience: Widely studied for malaria and autoimmune disease, providing a robust safety record.
- Generic hydroxychloroquine is available and may offer cost savings while delivering the same active ingredient.
Dosage, Administration, Lifestyle and Dietary Recommendations
Recommended Dosage
- 200 mg tablet: Usually taken once daily or as directed by a healthcare professional.
- 400 mg tablet: May be prescribed as a loading dose (e.g., two tablets on day 1) followed by 200 mg daily, depending on the condition.
How to Take
- Swallow the tablet whole with a full glass of water.
- Take with or without food; a meal may reduce stomach upset.
- Do not crush or chew the tablet.
Missed Dose
If you remember within 12 hours, take the missed tablet. If it is longer than 12 hours, skip it and resume your regular schedule. Do not double-dose.
Overdose
Seek emergency care immediately if you experience severe Nausea, Vomiting, visual changes, or cardiac symptoms. Bring the medication packaging to aid healthcare providers.
Special Populations
- Elderly: Start at the lower end of the dosage range; monitor kidney function.
- Renal or hepatic impairment: Dose adjustment may be required; close clinical supervision is essential.
- Pregnancy & breastfeeding: Discuss risks with your clinician; hydroxychloroquine crosses the placenta.
Lifestyle & Diet
- Avoid grapefruit and grapefruit juice as they can affect drug metabolism.
- Limit excessive alcohol consumption, which may increase liver strain.
- Maintain adequate hydration to support renal clearance.
Precautions and Warnings
- Perform baseline eye examinations; hydroxychloroquine can cause retinal toxicity with long-term use.
- Monitor blood glucose, especially in diabetic patients, as the drug may affect glycemic control.
- Notify your clinician of any heart rhythm disorders; hydroxychloroquine can prolong the QT interval.

Frequently Asked Questions
How quickly will I feel better after starting Plaquenil?
Most patients notice symptom improvement within 1-2 weeks, but full therapeutic effect for autoimmune conditions may take up to 3 months.
Can I drink coffee while taking Plaquenil?
Moderate coffee intake is acceptable; however, avoid large amounts of grapefruit juice as it interferes with drug metabolism.
Is it safe to take Plaquenil with my blood pressure medication?
Generally yes, but beta-blockers and certain calcium channel blockers may increase the risk of heart rhythm changes; consult your clinician for a personalized review.
What should I do if I experience mild nausea?
Take the tablet with food or a light snack and stay hydrated. If nausea persists, inform your healthcare provider.
Does Plaquenil protect me from viral infections like COVID-19?
Current evidence does not support routine use for COVID-19 prevention. Use only as directed for approved indications.
Can I stop taking Plaquenil abruptly?
Do not discontinue suddenly without medical advice; tapering may be needed to avoid disease flare-ups.
Are there any travel considerations when using Plaquenil?
For malaria prophylaxis, start the medication 1-2 days before travel, continue daily, and finish 7 days after leaving the endemic area.
How often should I have eye exams while on Plaquenil?
Baseline exam before starting, then annual screening after 5 years of use, or sooner if you develop visual symptoms.

Reviews
Just hit the three-month mark on 200mg and finally feeling the difference in my joints. The morning stiffness is maybe 60% better. But seriously, the stomach cramps in the first month were brutal. My rheumatologist told me this, but I didn't listen: TAKE IT WITH A FULL MEAL. Not just a snack. A real dinner. It completely solved the nausea issue for me. Worth the wait, honestly.
Started Plaquenil two weeks ago for mild SLE and I feel like I have perpetual jetlag. The headaches are constant, especially behind the eyes. I'm only on 200mg daily. Is this normal? My doctor mentioned the eye checks, which is terrifying, but the lethargy right now is making me question if I should stick it out. Hoping the side effects settle down soon like everyone says they do.
Been cycling 400mg daily for over five years for my RA. It keeps the inflammation manageable, but my system is now super sensitive to UV. Living in Manila, that means I have to be religious with SPF 50+. A small user hack: I split my 400mg dose into two 200mg pills, one in the morning, one at night. Less GI drama that way, and the concentration seems steadier. Essential med, just watch the sun.
The good news: My skin symptoms (Dermatitis) have cleared up significantly after nine months. The bad news: My hair is thinning. It's not massive clumps, but definitely noticeable recession along the temples. I've introduced biotin and collagen but not seeing much help. Still, I'd rather deal with hair loss than the awful rashes. This drug is a serious balancing act.
Took this for undifferentiated connective tissue disease. It helped my joint pain initially, but I started developing really intense vivid dreams and sometimes insomnia. I talked to my pharmacist, and she suggested taking the pill right after dinner, around 7 PM, instead of close to bedtime. That slight schedule shift drastically reduced the weird nighttime effects. Still on it, it's effective if you can manage the side effects.
This medication feels like it takes forever to kick in. I started 6 weeks ago and saw minimal change, but Week 7 hit and suddenly the fatigue lifted. I'm less dependent on ibuprofen now, which is a massive win for my liver. Word of caution though: DO NOT mix this pill with grapefruit juice. Learned that the hard way. Felt flushed and dizzy that afternoon. Stick to water or plain yogurt.
Been on 200mg for Systemic Sclerosis for two years. My raynaud's phenomenon is better controlled, but the retinal toxicity fear is real. I insist on the advanced visual field testing every six months now. It keeps my rheumatologist and ophthalmologist talking to each other, which is crucial. It’s effective-but you have to be proactive about the checkups. Don't skip them.
My joint inflammation is mostly resolved, thank goodness. However, my skin has become inexplicably dry-like painfully dry patches on my elbows and shins, something I never had before Plaquenil. I noticed if I take high-dose fish oil with the hydroxychloroquine pill, the dryness doesn't bother me as much. Maybe it's mitigating the drying effect? Hard to say, but it works for me.
