So my rheumatologist told me to stop taking leflunomide as it was causing me increasing numbness and mild pain in my feet and hands. I started this (20 mg/day) on September 25, 2021 and it did succeed in getting me to 5.5 mg so far.
She prescribed a 10 day dose of Olystr which she claims will help flush the leflunomide out of my system a little quicker.
Just wanted to share in case you run into the same issue.
