Precautions to keep in mind

Check with your doctor immediately if blurred vision, difficulty in reading, or any other change in vision occurs during or after long-term treatment. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).

If your symptoms do not improve within a few days (or a few weeks or months for arthritis), or if they become worse, check with your doctor.

Hydroxychloroquine may cause blurred vision, difficulty in reading, or other change in vision. It may also cause some people to become dizzy or lightheaded. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert or able to see well. If these reactions are especially bothersome, check with your doctor.

Malaria is spread by mosquitoes. If you are living in, or will be traveling to, an area where there is a chance of getting malaria, the following mosquito-control measures will help to prevent infection:

• If possible, sleep under mosquito netting to avoid being bitten by malaria-carrying mosquitoes.
• Wear long-sleeved shirts or blouses and long trousers to protect your arms and legs, especially from dusk through dawn when mosquitoes are out.
• Apply mosquito repellent to uncovered areas of the skin from dusk through dawn when mosquitoes are out.
