Which class is used to treat malaria and rheumatoid arthritis unresponsive to NSAIDs and can cause dizziness and itching?

• A. Antimalarials
• B. Antihistamines
• C. Antibiotics
• D. Anti-inflammatory

Answer: (A)

Antimalarials are used for both malaria and as disease-modifying therapy in rheumatoid arthritis when NSAIDs aren’t enough. Drugs in this class, like hydroxychloroquine, help modulate immune activity and reduce joint inflammation, making them useful for RA that doesn’t respond to NSAIDs. A common part of their side effect profile is dizziness and itching, especially early in treatment; other potential effects include GI upset and headaches, with long-term use carrying a risk of retinal toxicity that requires regular eye monitoring. They are not antihistamines, antibiotics, or typical anti-inflammatories, which is why this class best fits the described uses and adverse effects.
