What is Plaquenil 200 mg (Hydroxychloroquine)?
Plaquenil 200 mg is a brand name for Hydroxychloroquine, a medication primarily used to treat malaria and autoimmune diseases such as rheumatoid arthritis and lupus erythematosus. Hydroxychloroquine belongs to a class of drugs known as antimalarials and disease-modifying antirheumatic drugs (DMARDs). It works by modulating the immune system and reducing inflammation in autoimmune conditions while also targeting the parasites that cause malaria.
Hydroxychloroquine is available in tablet form, and the 200 mg dosage is commonly prescribed for various conditions, including prevention and treatment of malaria and management of autoimmune diseases.
How Does Plaquenil 200 mg (Hydroxychloroquine) Work?
Hydroxychloroquine works through different mechanisms depending on the condition being treated:
- Malaria Treatment:
Hydroxychloroquine prevents the growth and spread of the Plasmodium parasite, which causes malaria. It does this by interfering with the parasite’s ability to digest hemoglobin within red blood cells. This action prevents the parasite from multiplying and spreading throughout the body. - Rheumatoid Arthritis:
In autoimmune diseases like rheumatoid arthritis, hydroxychloroquine helps modulate the immune system by reducing the production of inflammatory cytokines and immune complexes. These compounds contribute to the inflammation and joint damage seen in rheumatoid arthritis, so by reducing them, hydroxychloroquine helps alleviate symptoms like pain, swelling, and stiffness. - Lupus Erythematosus:
For lupus, Plaquenil 200 mg helps manage symptoms such as skin rashes, fatigue, and joint pain. It works by suppressing the overactive immune system that attacks healthy tissues, reducing inflammation and preventing flare-ups. Hydroxychloroquine also helps prevent long-term damage to organs affected by lupus.

Plaquenil is also used to treat skin rashes associated with lupus and other autoimmune diseases. It helps improve the appearance of the skin and reduces the severity of lesions. - Prevention of Disease Flare-ups:
By modulating the immune system, Plaquenil 200 mg helps reduce the likelihood of disease flare-ups, especially in autoimmune conditions like lupus and rheumatoid arthritis.
How to Take Plaquenil 200 mg Tablets
- Dosage:
The typical dosage of Plaquenil 200 mg depends on the condition being treated. For malaria, the usual dose is 400 mg once a week for prevention or 400 mg daily for treatment, as prescribed by your doctor. For rheumatoid arthritis and lupus, the usual starting dose is 400 mg daily, but the dose may be adjusted based on your response to the medication. - Administration:
Plaquenil 200 mg tablets should be taken with food to reduce the risk of stomach upset. Swallow the tablet whole with a full glass of water. Do not chew or crush the tablet. - Missed Dose:
If you miss a dose, take it as soon as you remember. If it is close to the time for your next dose, skip the missed dose and continue with your regular schedule. Never take two doses at once to make up for a missed dose. - Consistency:
For optimal results, take Plaquenil 200 mg exactly as prescribed. Do not stop taking the medication without consulting your doctor, even if you feel better, as this may lead to a relapse of symptoms.

Is Plaquenil 200 mg Safe for Humans?
Plaquenil 200 mg is generally safe for most people when used as prescribed by a healthcare provider. However, as with any medication, there are potential risks and side effects. It is important to inform your doctor of any pre-existing conditions, especially heart disease, liver or kidney issues, or eye problems.
Hydroxychloroquine can affect the retina (the light-sensitive tissue at the back of the eye), and long-term use can lead to retinal damage. For this reason, regular eye exams may be recommended for patients on long-term therapy. Hydroxychloroquine should be used with caution during pregnancy and breastfeeding, and only if deemed necessary by a healthcare provider.
