Thank you for your reply. I'm not on any beta blockers. I never had asthma before but did have pneumonia about 5 years ago. My diagnosis is post-covid asthma. The Pulmicort is taken through a nebulizer, morning and night. It's a glucocorticosteroid and its active ingredient is budesonide. The bronchodilator I take is inhaled as needed. I didn't need the latter all summer. Suddenly, I need to use it a couple of times a day again. Very frustrating. I wish you luck on your quest for treatment. Let's definitely keep each other updated.
