Hydroxychloroquine is considered a preferred agent in which situation?

• A. Osteoarthritis
• B. Pregnancy
• C. Acute infection
• D. Gout

Answer: (B)

Hydroxychloroquine is favored during pregnancy because it has a well-established safety profile for the fetus and helps prevent maternal autoimmune disease flares, which are particularly dangerous in pregnancy. In conditions like systemic lupus erythematosus that can worsen during gestation, continuing hydroxychloroquine reduces disease activity and improves pregnancy outcomes, with extensive data supporting its relative safety at standard doses. It’s not used for osteoarthritis, which is a degenerative, non-inflammatory joint condition, not driven by the immune pathways hydroxychloroquine targets. It isn’t a first-line treatment for acute infections or for gout, where other medications are preferred. Thus, its use in pregnancy is the scenario where it is considered a preferred agent.
