Yes the medication are correct.
Rednisol is a steroid. Since you are an asthmatic pt, your doctor has given you this medicine. (Even if oxygen levels are normal)
In a non asthmatic patient with covid, rednisol is given only when the pt has low saturation below 94%
Next Steps
please monitor saturation thrice a day.
follow CARP, rotate posture in bed every 2 hrs
do not exert yourself.
your body needs rest to recover from the infection.
steam inhalation and betadine gargles thrice a day will help.
