There is a small possibility that you are allergic to the
ipratropium bromide (Atrovent), which is one of the two components of Combivent. The other component is albuterol. Strange as it may seem, ipratropium bromide is made from PEANUTS, one of the foods that almost every asthmatic is allergic to. I am allergic to peanuts, but my combivent helps my asthma.
No asthma medication will give long-lasting relief, if you are still exposing yourself to the trigger or triggers that are making you sick.
