Plaquenil 200 mg Tablet (Hydroxychloroquine) is a prescription medication used in the USA, UK, and Canada to treat and prevent several conditions, including malaria, rheumatoid arthritis, and systemic lupus erythematosus (SLE). It contains the active ingredient hydroxychloroquine, which is classified as a disease-modifying anti-rheumatic drug (DMARD) and an antimalarial agent.
In malaria prevention, Plaquenil 200 mg works by interfering with the growth and activity of parasites transmitted through mosquito bites. It is commonly taken before, during, and after travel to regions where malaria is prevalent, in accordance with CDC and WHO guidelines. When used as a preventive treatment, the medication helps lower the risk of infection and is considered a trusted option for travelers and residents in at-risk areas.
Beyond malaria, Plaquenil is widely prescribed for autoimmune conditions. In rheumatoid arthritis, it helps reduce joint pain, swelling, and stiffness, while slowing the progression of joint damage to improve long-term mobility. For patients with systemic lupus erythematosus (SLE), the medication helps control inflammation, reduce flare-ups, and protect organs from immune system–related damage. Because Plaquenil modifies the immune response, it can take weeks or months for patients to notice improvements, making consistent use essential.
Plaquenil 200 mg Tablet should be taken exactly as prescribed by a healthcare professional, usually with food to reduce stomach irritation. The dosage depends on the medical condition, age, and body weight, particularly in children. While generally well tolerated, some people may experience side effects such as nausea, headache, vision changes, or dizziness. Patients should seek medical attention if they notice eye problems or severe allergic reactions. Long-term use may require regular eye exams to monitor potential retinal changes.
As a versatile treatment option, Plaquenil 200 mg Tablet remains an important medication in the United States, United Kingdom, and Canada for managing malaria prevention and autoimmune diseases like rheumatoid arthritis and lupus. Patients are advised to follow their doctor’s guidance closely to ensure safe and effective use.
