Contraindications
There are no contraindications for inhaled ipratropium, apart from hypersensitivity to atropine and related substances. For oral administration, contraindications are similar to other anticholinergics; they include narrow angle glaucoma and obstructions in the gastrointestinal tract and urinary system.
Ipratropium bromide inhalers often contain soy lecithin and peanut oil as excipients, so allergies to these plants is also a contraindication.
