Safety Profile and Monitoring of Hydroxychloroquine Therapy Hydroxychloroquine is generally considered a safe medication when prescribed at recommended doses. Most patients tolerate it well, with mild gastrointestinal symptoms such as nausea or abdominal discomfort being the most common side effects. One of the most important safety considerations is retinal toxicity, which can occur with long-term use or high cumulative doses. Regular ophthalmologic examinations are recommended to detect early changes before vision is affected. Other potential side effects include skin reactions, headache, and, rarely, cardiac conduction abnormalities. Patients with pre-existing heart or eye conditions require closer monitoring. Dose adjustment may be necessary for individuals with kidney or liver impairment. Patient education plays a crucial role in ensuring safe use, particularly regarding adherence to prescribed doses.
