Second RT PCR test positive. Of high bp.

My mother was found covid Positive via antigen test on 30 Apr with hrct Score of 16 out of 25. From 2nd May she was on covid specific medication  faviflu 400, ivermectin 12mg, Defcort 30 mg, Cameriv 2.5, Zincovit, Vitamin D 60 k daily, Celin 500,Grillinctus BM Syrup, Doxt 100 till 16 may as directed by the doctor. However her second covid Test on 16 may again came out positive in RT PCR with CT Value 32.46. Now the doctor has suggested to carry on all meds except fabiflu for another two weeks. I am a bit sceptic about prolonged dosage of steroids as defcort 30. As her oxygen saturation remains mostly in the 94-95 range,is it really necessary to continue all meds. Kindly advise as she is a patient of high BP.
