Hydroxychloroquine is a disease-modifying anti-rheumatic drug (DMARD) that reduces inflammation and modulates the immune system. It is utilized in the management of systemic lupus erythematosus and rheumatoid arthritis. As a vital ingredient in trusted generic medications, it provides a stable treatment option for chronic conditions. Our UK pharmacy offers verified access to quality pharmaceutical products containing Hydroxychloroquine.
Hydroxychloroquine is a synthetic compound that belongs to the antimalarial family of medicines. It was first created to treat malaria but has since become a regular part of therapy for certain autoimmune disorders. In the UK you will most often find it marketed under the name Plaquenil.
The best-known product that contains hydroxychloroquine is Plaquenil. It is available in tablet form, usually in 200 mg strengths. Plaquenil is sold both as a brand-named medicine and as a generic version that carries the same active ingredient. The tablets can be taken whole or, for those who have difficulty swallowing, the tablets may be split according to the specific product’s instructions. Plaquenil is the only hydroxychloroquine-containing medication that is routinely supplied on the National Health Service (NHS) in the United Kingdom.
