Can hydroxychloroquine affect other medicines and treatments?
Hydroxychloroquine is commonly used alongside other disease-modifying drugs including methotrexate – especially for rheumatoid arthritis.
However, some drugs can interact with hydroxychloroquine. Indigestion remedies (for example, antacids including some over-the-counter preparations) can stop hydroxychloroquine being absorbed. It's recommended you wait at least four hours after taking hydroxychloroquine before you take an indigestion remedy.
Discuss any new medications with your doctor before starting them, and always mention you're on hydroxychloroquine if you're treated by anyone other than your usual healthcare team.
Can I have vaccinations while I'm on hydroxychloroquine?
You can have vaccinations, including live vaccines such as yellow fever and shingles, while you're on hydroxychloroquine.
Even though hydroxychloroquine is an anti-malarial drug, don't assume it will protect you of you're travelling to an area where there's a risk of malaria. Always check with a healthcare professional what precautions you need to take against malaria.
