Since the unit-dose vials contain no preservative, it is important that the contents are used soon after opening and that a fresh vial is used for each administration to avoid microbial contamination. Partly used, opened or damaged unit-dose vials should be discarded.
Unused vials should be discarded three months after opening of the pouch.
It is strongly recommended not to mix ipratropium bromide + salbutamol (Combivent UDV) solution for inhalation with other drugs in the same nebulizer.
