Hydroxychloroquine (brand name Plaquenil) is commonly used in the treatment of lupus SLE and Rheumatoid Arthritis. Originally an anti-malarial drug, it was found to be very effective in the treatment of Lupus SLE. It is a Disease Modifying Anti-Rheumatic Drug (DMARD). It works by dampening the underlying disease process and reducing inflammation, rather than just treating the symptoms. It can take 12 weeks or longer to notice any benefit. Risks and side effects are uncommon with this drug, but very rarely it may cause damage to the retina of the eye. There is however evidence that this risk can be almost completely eliminated if the doctor adjusts the dose carefully.

Before starting this medication you may have a blood test to check your liver and kidneys are working properly.

It is also advisable to have an eye check before you start the medication and then at least once a year afterwards. An optician can carry out this check for you.
