My Husband says it really helps keep his Asthma under control. Without it, he has constant low-level Asthma with flareups from almost everything (pollen, certain foods, exercise, etc.). He's not aware of any side-effects from it.
As for interactions with other meds, that's a better question to ask your pharmacist - they are trained about this in their pharmacy schooling.
