Table of contents:

Plaquenil (also known as hydroxychloroquine sulfate) is a prescription medication used to treat or prevent malaria caused by mosquito bites. It belongs to a class of medications known as disease-modifying antirheumatic drugs (DMARDs). It can reduce skin problems in lupus and prevent swelling/pain in arthritis.

Plaquenil tablets contain 200 mg of hydroxychloroquine sulfate and are available for oral administration. Hydroxychloroquine can be used as a disease-modifying anti-rheumatic drug (DMARD) to help decrease pain and swelling associated with arthritis.

Uses and Dosages

Plaquenil comes in the form of a tablet to take by mouth exactly as directed by your doctor, usually once a week on the same day of each week. To prevent stomach upset, take Plaquenil with food or milk. Do not crush or break the tablets, as they may leave a bitter taste. You should mark a calendar to help you remember. Plaquenil is usually started 1 to 2 weeks before entering an area with widespread malaria. Continue taking it weekly while in the area and for 4 to 8 weeks after leaving, or as directed by your doctor. Finally, to treat malaria, follow your doctor's instructions.

The dosage and length of treatment are based on your medical condition and response to treatment. Children's dose is also based on weight. The recommended dosage for adults with chronic discoid lupus erythematosus is 200mg to 400mg in a day of the week, while the initial dosage for treating other conditions such as rheumatoid arthritis or malaria is higher, usually around 400mg to 600mg in a day of the week, and then decreased to 200mg or 400mg per in a day of the week as a maintenance dose.
