Buy Hydroxychloroquine Online (HCQ) has been at the center of much attention due to its potential role in treating COVID-19. Originally used to treat malaria, HCQS 200 mg has garnered interest for its possible effectiveness against the novel coronavirus. However, it’s essential to understand its uses, benefits, and potential side effects before considering its use.

Uses of hydroxychloroquine:


HCQS 200 mg is primarily used to prevent and treat malaria caused by Plasmodium vivax, P. malariae, P. ovale, and certain strains of P. falciparum. It is often used in combination with other antimalarial drugs.

Autoimmune Diseases:

HCQS 200 is used to treat autoimmune diseases such as rheumatoid arthritis, lupus erythematosus, and Q fever. It helps reduce inflammation and control symptoms in these conditions.

HCQS 200 mg has anti-inflammatory properties, making it useful in managing autoimmune diseases like rheumatoid arthritis and lupus. It helps reduce joint swelling, pain, and stiffness.

Potential COVID-19 Treatment:

While still under study, HCQ has shown some potential in reducing the severity of COVID-19 symptoms. It is believed to interfere with the viral entry into cells and inhibit viral replication, though more research is needed to confirm its efficacy.

Side Effects:

Gastrointestinal Issues:

Common side effects include nausea, vomiting, diarrhea, and abdominal pain. Taking HCQ with food can help alleviate these symptoms.

Skin Reactions:

HCQS 200 mg can cause skin rashes, itching, and sensitivity to sunlight. It’s important to use sunscreen and protective clothing when outdoors.

Eye Problems:

Long-term use of HCQ can lead to retinal toxicity, which may cause vision changes. Regular eye examinations are recommended for those on prolonged HCQ therapy.

Cardiac Effects:

HCQ can prolong the QT interval in the heart, which can lead to serious heart rhythm abnormalities. It should be used cautiously in patients with underlying heart conditions.


Malaria Prophylaxis:

The typical dosage for malaria prevention in adults is 400 mg once a week, starting 2 weeks before entering an endemic area and continuing for 4 to 8 weeks after leaving the area.

Malaria Treatment:

For malaria treatment in adults, the dosage is 800 mg initially, followed by 400 mg at 6 hours, 24 hours, and 48 hours after the initial dose.

Rheumatoid Arthritis and Lupus:

The usual dosage for these conditions is 400 to 600 mg per day, taken as a single daily dose or divided into two doses.

If HCQ is used for COVID-19 treatment, the dosages can vary. It’s essential to follow the specific dosing regimen prescribed by your healthcare provider.


  1. Medical Supervision: HCQS 200 should only be used under the supervision of a healthcare provider. Do not self-prescribe or take HCQS 200 mg without medical advice.
  2. Eye Exams: Regular eye examinations are recommended for individuals taking HCQ long-term, as the medication can cause retinal toxicity.
  3. Heart Health: HCQ can prolong the QT interval in the heart, which may increase the risk of arrhythmias. It should be used with caution in patients with heart conditions.
  4. Liver and Kidney Function: HCQ should be used cautiously in patients with liver or kidney disease, as the drug is primarily metabolized in the liver and excreted by the kidneys.
  5. Skin Sensitivity: HCQ can increase sensitivity to sunlight, leading to sunburn or skin rash. Use sunscreen and protective clothing when outdoors.
  6. Drug Interactions: HCQ can interact with other medications, including certain antibiotics, antacids, and anti-seizure drugs. Inform your healthcare provider about all medications you are taking before starting HCQ.


HCQS 200 mg is a versatile medication with uses ranging from malaria prevention to managing autoimmune diseases. While it has shown promise in treating COVID-19, its efficacy and safety profile for this indication are still being studied. It’s crucial to use HCQS under medical supervision and be aware of its potential side effects. As research on HCQS continues, more definitive conclusions regarding its role in COVID-19 treatment will hopefully emerge.
