Plaquenil Oral Uses
Hydroxychloroquine is used to prevent or treat malaria infections caused by mosquito bites. It does not work against certain types of malaria (chloroquine-resistant). The United States Center for Disease Control provides updated guidelines and travel recommendations for the prevention and treatment of malaria in different parts of the world. Discuss the most recent information with your doctor before traveling to areas where malaria occurs.
This medication is also used, usually with other medications, to treat certain auto-immune diseases (lupus, rheumatoid arthritis) when other medications have not worked or cannot be used. 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, though it is not known exactly how the drug works.
How To Use Plaquenil Oral
Hydroxychloroquine is usually taken with food or milk to prevent stomach upset. The dosage and length of treatment are based on your medical condition and response to therapy. In children, dosage is also based on weight. For malaria prevention, take this medication by mouth once a week on the same day of the week, or as directed by your doctor. Mark a calendar to help you remember. This drug is usually started 2 weeks before entering the area with malaria. Take it once weekly while in the area, and continue taking it for 4 to 8 weeks after leaving the area or as directed by your doctor. To treat malaria, follow your doctor's instructions.
For lupus or rheumatoid arthritis, take this medication by mouth, usually once or twice daily or as directed. Your doctor may gradually increase your dose. Once you have been taking the medication for a while and your condition has improved, your doctor may instruct you to lower your dose until you find the dose that works best with the fewest side effects.
Use this medication regularly in order to get the most benefit from it. If you are taking it on a daily schedule, take it at the same time each day. Take this medication exactly as prescribed. Do not stop taking it without talking with your doctor, especially if you are taking it for malaria. It is important to continue taking this for the length of time prescribed. Stopping prevention or treatment too soon may lead to infection or a return of the infection.
Inform your doctor if your condition persists or worsens. It may take several weeks or months to see improvement if you are taking this for lupus or arthritis. Hydroxychloroquine may not prevent malaria in all cases. If you experience fever or other symptoms of illness, seek immediate medical attention. You may need a different medication. Avoid exposure to mosquitoes. (See also Notes section.)
