Ang, I had hair loss pretty severe when I first started on Prednisone, Plaquenil, and Methotrexate. I guess it may depend on the dosage, and hopefully your hair loss will stop as mine did after a few months. My scalp was very sensitive at that time too and it hurt just to shampoo. In my case, it stopped and altho I have what I consider 'thinning' hair, it may or may not be due to my meds now, but it definitely was related in the beginning.
I didn't stay on Plaquenil for long tho since it had an almost immediate reaction to my eyes. I know this is a side effect for some people and you should be regularly seeing an opthamologist while you are on Plaquenil (I'm not a dr, but I do know that it is usually brought to your attention when they put you on this particular medicine).
I certainly didn't lose any weight - and really gained fat in places I never had it before when I went on Prednisone. (I used to have an angular face - it can't get much rounder now tho)😉
I take 5000 units of D3 everyday and did find that I had quite a low Vit D when I don't take it
I would make sure to tell your RA dr. about all your symptoms in your next visit.
I hope the meds will kick in soon to help with your pain. There is always that period of time of waiting before we notice improvements. Hang in there.
Sincerley,
