Which allergy is listed as a contraindication to Ipratropium Bromide?

• A. Peanuts
• B. Seafood
• C. Gluten
• D. Latex

Answer: (A)

Allergic reactions to medications can come from the active drug or from ingredients used in the formulation (excipients). Some ipratropium bromide inhalation products have included peanut-derived components such as peanut oil or peanut lecithin. For patients with peanut allergy, exposure to these excipients could trigger an allergic reaction, so peanut allergy is listed as a contraindication. The other options—seafood, gluten, and latex—do not have a known, direct contraindication relationship with ipratropium bromide itself.
