Hydroxychloroquine (also known as hydroxychloroquine sulfate) is an arthritis medicine that also can be used to prevent malaria. It is available in the United States by prescription only. It is sold under the brand name Plaquenil and it is also sold as a generic medicine. It is available in tablets of 155mg base (200mg salt). You should know that the 155mg base tablet is the same as the 200mg salt tablet. It is just two different ways of describing the same thing. Hydroxychloroquine can be prescribed for either prevention or treatment of malaria. This fact sheet provides information about its use for the prevention of malaria infection associated with travel.
