Hi & Welcome.
I can understand your concern.
Since
rheumatoid arthritis is an
autoimmune disease which results in production of auto antibodies (against self) that damage the articular surfaces of the joints, the treatment in most of the cases is life long.
Hydroxychloroquine Sulfate (HCQS) is a disease-modifying anti-rheumatic drug (DMARD), because it can decrease the pain and swelling of arthritis, and it may prevent joint damage and reduce the risk of long-term
disability.
Symptoms start to improve in 1-2 months, but it may take up to 6 months before the maximum benefits of this medication are experienced.
Generally it is a safe drug, however the most important toxicities are on the eyes like corneal deposits, weakness of the eye muscles, loss of accommodation (and sensitivity to light), & a
retinopathy that may progress to irreversible visual loss can occur.
As a matter of fact before starting long-term treatment with HCQS, a patient should be given a careful eye exam. Eye exams should be conducted annually during the period of treatment.
Hope this answers your query.
