Q: 22 year old female with severe peanut allergy presented to ER with asthma execerbation. Which commonly use drug should be avoided or at least be use with caution in this patient?



Answer: Atrovent

Actually, nebulized Atrovent doesn't pose a problem, but it was the soy lecithin additive in the propellant in the MDI's that could trigger a reaction in those with peanut and/or soy hypersensitivity.
