Budamate 200 inhaler used for five days.

I was COVID +ve in April and I was in home isolation with normal spo2.I was not prescribed any kind of steroid only took multivitamins+Azithral(5days) as prescribed by my physician.I recovered around 20 April but I had some breathing problem as I was feeling my breathing was not fulfilling.So then I consulted a pulmonologist on 8th May (approx 1 month after my first COVID symptom) for this problem he prescribed me Budamate 200mcg inhaler 2 puffs day and night.I did this medicine for 5 days and my breathing issue resolved and I stopped taking it. My concern is that as budamate contains Budesonide which is a steroid can it cause any side effects such as black fungus ? It's been 15 days since I stopped the inhaler.I am not diabetic or obese.
