Are you asking about hydroxychloroquine or plaquenil? That is the only drug I can think of which might be "hcqs".
Plaquenil is often prescribed for rheumatoid arthritis. It does have potential side effects including eye problems, stomach difficulties, and severe tiredness. There can be other side effects as well, but I recommend that you talk to your rheumatologist and pharmacist about the benefits and risks of taking any medication for you RA.
Before I tried plaquenil, I needed to have my eyes examined to make sure that they were healthy. Eyes need to be checked again six months after starting plaquenil. I didn't stay on plaquenil very long because it made me extraordinarily tired (not a common side effect).
