Plaquenil (Hydroxychloroquine) 200mg Tablet 60s (Box)

Plaquenil 200mg Tablet is a well-established prescription medicine belonging to the antimalarial and disease-modifying antirheumatic drug (DMARD) class, with hydroxychloroquine sulfate as its active ingredient. If you or someone you care about in Singapore has been diagnosed with an autoimmune condition, your doctor may have recommended this tablet as part of a long-term management plan.

Like most medicines, Plaquenil can cause some side effects — the ones most commonly reported include nausea, headache, skin rashes, and stomach discomfort — though many people tolerate it well over time. It is important to know that this medicine works gradually, so patience and consistency are key, and you should never adjust your dose without speaking to your doctor first. We want Singaporean patients to feel confident and informed every step of the way, so please read through this product information carefully before starting or continuing your treatment.

Plaquenil (Hydroxychloroquine) 200mg Tablet 60s (Box) is primarily indicated for the treatment of autoimmune conditions such as rheumatoid arthritis and systemic lupus erythematosus, and for malaria prevention. It successfully fights parasite infections and reduces inflammation.

In Singapore, this medication is widely recognized by medical specialists for its disease-modifying properties, helping to prevent joint damage and long-term tissue complications in chronic autoimmune conditions. When used for antimalarial prophylaxis, it serves as an effective preventive treatment for Singaporean travelers visiting endemic regions. Because proper dosage management is critical to ensure patient safety and minimize potential side effects, this prescription-only medicine should be taken strictly under the guidance of a licensed doctor.

The commonly recommended adult dosage of Plaquenil 200mg Tablet ranges from 200mg to 400mg per day, taken as a single daily dose or divided into two doses, depending on the condition being managed and your doctor's assessment. Your prescribing doctor will determine the most appropriate dose for you based on your body weight, kidney function, and overall health status — so always follow their guidance precisely.

Plaquenil 200mg Tablet should be taken orally with food or a glass of milk to help reduce the chance of stomach upset. Swallow the tablet whole with water and try to take it at the same time each day to maintain a consistent level of the medicine in your body.
