The Beurer IH 55 is an inhaler that is suitable for the nebulisation of medication. Although the specific medications Atrovent, Pulmicort and Ventolin are not explicitly mentioned in the manual, the IH 55 is designed for use with medications that are suitable for inhalation. It is advisable to have the compatibility of these medications with the device confirmed by the manufacturer or a doctor to ensure that they will work with the IH 55's oscillating diaphragm technology.
