Key takeaways
Quinine (Qualaquin) and hydroxychloroquine (Plaquenil) are both antimalarial medications, but they have different uses and side effects. Quinine is specifically used to treat malaria in people aged 16 and older and must be taken every 8 hours for 7 days. It has many side effects, including nausea, stomach pain, and serious risks like abnormal heart rhythms and bleeding problems. Hydroxychloroquine, on the other hand, is used to prevent and treat malaria in both adults and children, and it is also used to treat rheumatoid arthritis and lupus in adults. It is typically taken once or twice a day with food or milk. Common side effects include nausea, vomiting, and diarrhea, but it can also cause serious issues like heart rhythm problems and eye damage. Both medications are available as a lower-cost generic, making them more affordable. Both medications require a prescription and have significant interactions with other medications, so it's important to discuss all your medications with your healthcare provider.
