I have had astma all my life but I need something stronger to help me breath better?

Review. Review your symptoms and your medication with your doctor and have pulmonary function tests. Get recommendations from him or see a pulmonologist. All the best.
Please see your. Doctor or a pulmonary specialist or allergist for a further workup and possible change in your therapy. If you are having difficulty breathing, you should be seen ASAP at an emergency room.
