• QHow often should I be examined by an ophthalmologist if I take Plaquenil?

  A Dr. Wayne Bizer , Ophthalmology, answered on behalf of American Academy of Ophthalmology's EyeSmart

  Plaquenil (hydroxychloroquine) is a very important medication in the prevention and treatment of malaria and in the treatment of rheumatoid arthritis and lupus. It can do great things for you and can do serious things to you, including permanently reducing the clearness of your vision. Your prescribing doctor will likely advise you to see an ophthalmologist (eye doctor) as you begin taking Plaquenil to try to protect you from any eye complications. The damage that Plaquenil causes to your eyes cannot be reversed, so it is most important to catch any eye problems early, but stopping the medication will almost always stop any progression of blurred vision.

  
  The amount of Plaquenil required to cause these problems is somewhat dose-related, and therefore the frequency of problems goes up with the number of years and daily dosage taken. Your eye doctor will want to get photographs of your retinas, perform side-vision testing and color-vision testing, and measure your best vision level as you begin your Palquenil treatment. Your doctor will want to repeat these tests at various intervals, often every six months.

  
  All this being said, Plaquenil damage to the eyes is very rare. You should carefully discuss the risks and benefits of this medication with your prescribing physician and eye doctor.

  The main risk associated with using primaquine is hemolytic anemia. This form of anemia occurs when the number of red blood cells in the blood is insufficient. Symptoms of this disorder include dark urine, shortness of breath, jaundice, fatigue, fever, and rapid heartbeat. If not treated, hemolytic anemia can lead to death by causing the cardiovascular system to fail. Talk to your doctor if you experience any of these symptoms while taking primaquine.
  
  Primaquine also may cause heart rhythm changes in people with heart disease or heart rhythm disorders. Your doctor may give you tests to monitor your heart while you are taking primaquine.

  A Stacy Wiegman, PharmD , Pharmacy, answered

  Aralen (chloroquine) may cause a variety of strange side effects, including different types of visual problems. These include blurry or misty vision and difficulty focusing. If you are taking Aralen you should slowly return to performing activities requiring good vision and coordination, such as driving. Long-term or high-dose usage of similar drugs has caused irreversible vision loss in some patients. Before you take Aralen, you should discuss your complete medical history with your doctor, since the drug may affect you differently based on different conditions you have or have had. Also, be sure to discuss the possibility of changes in your vision.
