Why not prescribe Paxlovid?

23 nb AFAB currently infected with covid. I have celiac disease, Hashimoto's, hEDS, and some other unidentified autoimmune disease which causes swelling. I am also AuDHD. Most recent covid booster received in the fall. I have knowingly had covid once before in fall 2023 and had a moderate reaction, nearing severe. Had a persistent cough lasting for six months post infection which was treated with a steroid inhaler. This time I went to urgent care within 48 hours of being symptomatic and was prescribed prednisone and liquid promethazine. The urgent care doctor said he didn't want to prescribe Paxlovid, citing the nasty side effects and how hard it is on the kidneys. The urgent care doctor wasn't aware of my autoimmune diseases and I was too loopy to advocate for myself. I reached out to my PCP to get Paxlovid but she said she doesn't prescribe it to anyone, even taking into account my handful of autoimmune diseases. So... Why not prescribe Paxlovid to a patient like me? I know this is a question best asked to my own PCP, but I am looking to hear different medical perspectives on the matter. If it is just the negative side effects, what side effects are bad enough to completely disregard Paxlovid as an option? Is there literature to support prednisone as better than Paxlovid in terms of post infection outcomes/long covid prevention? Thank you in advance!
