How should I take this medicine?
Take Hydroxychloroquine 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 prevent malaria: Start taking the medicine 2 weeks before entering an area where malaria is common. Continue taking Hydroxychloroquine regularly during your stay and for at least 8 weeks after you leave the area.
To treat malaria: Your doctor may recommend a single dose of Hydroxychloroquine, or a high starting dose followed by a smaller dose during the last 2 days of treatment. Follow your doctor's instructions.
Take Hydroxychloroquine for the full prescribed length of time for malaria. Your symptoms may improve before the infection is completely cleared.
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.
While using Hydroxychloroquine, you may need frequent blood tests at your doctor's office.
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.
What if I miss a dose?
If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.
