Newswise — Denver, Colo. – Researchers found that 70% of patients received a dose of hydroxychloroquine that exceeded safety guidelines, and can potentially cause vision loss, in an inner city hospital. The research is being presented at the 2015 Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO) this week in Denver, Colo.

The study tracked dosing of patients in a single hospital outpatient service and compared the dosage to safety guidelines, which are based on a patient’s height and weight. The results highlight a need for better communication between eye care providers and prescribing physicians.

Hydroxychloroquine (Plaquenil®) is a commonly used medication to treat autoimmune diseases such as rheumatoid arthritis and lupus. Long term use of hydroxychloroquine can cause damage to the macula, the part of the eye responsible for central vision.Abstract Title: Avoiding the Bull’s Eye: Ensuring “On-Target” Hydroxychloroquine Dosing and Eye Screening in an Inner-City Hospital
