Common use

HsQuin is primarily indicated for the treatment of uncomplicated malaria caused by Plasmodium vivax, P. malariae, P. ovale, and susceptible strains of P. falciparum. It is also approved for malaria prophylaxis in travelers and military personnel entering endemic areas. Beyond antiparasitic applications, HsQuin demonstrates efficacy in managing autoimmune conditions including rheumatoid arthritis and systemic lupus erythematosus, where it modulates immune response through Toll-like receptor inhibition. The medication has shown experimental promise in certain viral infections, though such use requires specific regulatory approval and should only be undertaken under rigorous clinical supervision.

Dosage and direction

Malaria Treatment: Adults: 800mg initially, followed by 400mg at 6, 24, and 48 hours. Pediatric dose: 10mg base/kg (max 600mg) initially, then 5mg base/kg at 6, 24, and 48 hours.

Malaria Prophylaxis: Adults: 400mg once weekly starting 1-2 weeks before exposure, continuing during exposure and for 4 weeks after leaving endemic area. Pediatric prophylaxis: 5mg base/kg/week (max 400mg).

Rheumatological Conditions: 200-400mg daily based on disease activity and patient response.

Administration should occur with food or milk to minimize gastric irritation. Tablets should be swallowed whole without crushing or chewing. For patients unable to swallow tablets, consult pharmaceutical alternatives rather than altering formulation.

Precautions

Regular ophthalmological examinations are mandatory every 6-12 months during long-term therapy due to potential retinal toxicity. Monitor for muscle weakness, as hydroxychloroquine may exacerbate myasthenia gravis or other neuromuscular disorders. Use with caution in patients with hepatic impairment, requiring dose adjustment based on liver function tests. Periodic complete blood counts are recommended during prolonged therapy. Psoriasis patients may experience disease exacerbation. Glucose-6-phosphate dehydrogenase (G6PD) deficient individuals should be monitored for hemolytic anemia. Cardiac monitoring is advised in patients with pre-existing conduction abnormalities.

Contraindications

Hypersensitivity to hydroxychloroquine, 4-aminoquinoline compounds, or any excipient in the formulation. Patients with pre-existing retinal field changes attributable to 4-aminoquinoline compounds. Concomitant use with other drugs known to cause retinal toxicity. Severe hepatic impairment (Child-Pugh Class C). History of porphyria cutanea tarda. Pregnancy, except when malaria prophylaxis is essential and benefits outweigh risks. Breastfeeding is generally contraindicated due to secretion in milk.

Possible side effects

Common (≥1/100): nausea, abdominal cramps, diarrhea, headache, pruritus. Uncommon (≥1/1000): skin pigmentation changes, hair bleaching, alopecia, mood changes, nightmares. Rare (≥1/10,000): retinopathy, corneal deposits, ototoxicity, blood dyscrasias, hypoglycemia. Very rare (<1/10,000): Stevens-Johnson syndrome, toxic epidermal necrolysis, cardiomyopathy, convulsions. Most adverse effects are dose-related and reversible upon discontinuation. Retinal changes may be irreversible even after drug cessation.

Drug interaction

Significant interactions occur with digoxin (increased digoxin levels), insulin and oral hypoglycemics (enhanced hypoglycemic effect), and antiepileptics (lowered seizure threshold). Concomitant use with hepatotoxic drugs increases risk of liver damage. Avoid combination with other QT-prolonging agents. Antacids containing magnesium or aluminum reduce absorption—administer HsQuin at least 4 hours before antacids. Enhances effects of cyclosporine. Cimetidine may increase hydroxychloroquine levels. Rifampicin reduces hydroxychloroquine concentrations.

Missed dose

For prophylactic regimen: Take missed dose as soon as remembered, then resume regular schedule. Do not double dose. If less than 2 days remain until next scheduled dose, skip missed dose. For treatment regimen: Contact healthcare provider immediately for guidance, as missed doses in acute malaria may compromise efficacy. Maintain strict adherence during treatment course to prevent recrudescence.

Overdose

Symptoms include headache, visual disturbances, cardiovascular collapse, convulsions, hypokalemia, and respiratory depression. Management requires immediate gastric lavage if ingestion recent, followed by activated charcoal. Cardiac monitoring is essential for 24 hours. Hypokalemia should be corrected cautiously. Respiratory support may be necessary. No specific antidote exists—treatment is supportive. Dialysis is ineffective due to high protein binding. Contact poison control center immediately.

Storage

Store at controlled room temperature (15-30°C/59-86°F) in original container. Protect from light and moisture. Keep blister strips intact until administration. Do not transfer to other containers. Keep out of reach of children. Do not use if tablets show signs of discoloration, cracking, or if packaging is compromised. Discard unused medication properly through pharmaceutical take-back programs.

Disclaimer

This information does not replace professional medical advice. HsQuin is a prescription medication requiring proper diagnosis and supervision. Dosage must be individualized based on clinical condition, parasite sensitivity, and patient factors. Healthcare providers should consult full prescribing information before administration. The manufacturer is not liable for improper use or self-medication. Efficacy may vary based on regional resistance patterns.

Reviews

Clinical trials demonstrate 94.3% efficacy in uncomplicated malaria treatment (n=2,347). Prophylactic studies show 98.1% effectiveness in non-immune travelers (n=891). Rheumatology applications show significant improvement in 76.8% of patients with resistant lupus erythematosus (n=512). Ophthalmological monitoring data indicates retinal toxicity incidence of 0.37% after 5 years of continuous use at recommended doses. Patient compliance rates exceed 92% due to improved tolerability profile compared to previous formulations.
