How should I take hydroxychloroquine (Plaquenil)?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Take hydroxychloroquine with a meal or a glass of milk, unless your doctor tells you otherwise.
Hydroxychloroquine is sometimes given only once per week. Choose the same day each week to take this medication if you are on a weekly dosing schedule.

To treat malaria: Your doctor may recommend a single dose, or a high starting dose followed by a smaller dose 6 to 8 hours later for 2 days in a row. Follow your doctor's instructions.
Take this medicine for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated.
In addition to taking hydroxychloroquine, use protective clothing, insect repellents, and mosquito netting around your bed to further prevent mosquito bites that could cause malaria.
Contact your doctor as soon as possible if you have been exposed to malaria, or if you have fever or other symptoms of illness during or after a stay in an area where malaria is common.
When treating lupus or arthritis, hydroxychloroquine is usually given daily for several weeks or months. For best results, keep using the medication as directed. Talk with your doctor if your symptoms do not improve after 6 months of treatment.
If you take hydroxychloroquine long-term, your doctor may need to check your knee and ankle reflexes and also do blood tests on a regular basis to check for harmful side effects. Your vision may also need to be tested every 3 months. Do not miss any scheduled appointments.
No medication is 100% effective in treating or preventing all types of malaria. For best results, keep using the medication as directed. Talk with your doctor if you have fever, vomiting, or diarrhea during your treatment.
