Has anyone had experience w Leflunomide( Arava)?

I don’t see that drug mentioned on here. It’s in the same category as Methotrexate so not a biologic. I was diagnosed w PMR 17 months ago. At one point about 4 months ago I was put on Leflunomide in order to help taper the pred. I think it helps and I’m down to 3 mg pred ( with slight flare but trying to cope) My question is - do you taper off Leflunomide like Pred? Is 20 mg a sizable dose? I want to see an end to this but thinking Leflunomide only is better than ongoing Pred. Thanks
