Plaquenil Q & A
What is hydroxychloroquine (PlaquenilⓇ) toxicity?
Hydroxychloroquine (Plaquenil) is a medication that’s used to treat malaria, rheumatoid arthritis, systemic lupus erythematosus, and other autoimmune disorders. Its potential side effects include retinal toxicity which leads to retinopathy (disease of the retina). As the condition progresses, it results in what’s known as bull’s eye maculopathy and may also cause blind spots in your visual field.
What is bull’s eye maculopathy?
Maculopathy is a broad term for disease of the macula. The macula is a small area of tissue that lies at the center of your retina and provides central vision which you use for driving, reading, computer work, and a multitude of other tasks that require sight. “Bull’s eye” refers to the appearance of the visible changes noted on the macula if you’re experiencing maculopathy that can be related to hydroxychloroquine toxicity.
How common is hydroxychloroquine toxicity?
Hydroxychloroquine toxicity is relatively rare, but the risks increase rather significantly with long-term therapy of five years or more.
You’re also more at risk for this side effect of hydroxychloroquine if:
- Your daily dose is greater than 400 milligrams
- You have kidney or liver disease
- You have underlying retinal disease or maculopathy
- You are older than 60
It’s recommended that anyone planning to take hydroxychloroquine see an ophthalmologist for a comprehensive eye exam. This will help determine whether a different class of medication would be a better choice for your treatment.
It is also imperative, no matter the current health of your eyes, that you undergo annual screening for retinal changes while taking hydroxychloroquine. Dr. Lazar has the most sophisticated diagnostic tools available for identifying the signs of hydroxychloroquine toxicity that can appear pre-clinically before visual symptoms occur.
