Just read your post and wanted to offer a suggestion. My 8-yr-old son takes Pulmicort. I'm researching Singular which is why I'm posting. I have found that giving him Airborne has strengthened his immune system and hasn't interfered with his meds. It's an OTC that was invented by a schoolteacher. You might try it or add more Vitamin C to your diet. Good luck!
