Anaphylaxis due to proton pump inhibitors: current understanding and important clinical considerations.

Proton pump inhibitors (PPIs) are one of the most prescribed drug classes. PPIs are remarkably safe, with minimal side effects, most of which are related to drug's pharmacokinetic interaction profiles. However, hypersensitivity reactions can occur and anaphylactic reactions to PPIs have been described.

Hypersensitivity Reactions to Nonsteroidal Anti-Inflammatory Drugs among Adults: Clinical Features and Risk Factors for Diagnosis Confirmation.
