What should patients be advised to do if they experience facial swelling while taking Benazepril Hydrochloride?

Facial swelling while taking Benazepril Hydrochloride can be indicative of a serious allergic reaction called angioedema, which requires immediate medical attention. This reaction, although rare, can lead to potentially life-threatening complications, especially if it affects the airway.

Advising patients to seek immediate medical attention is critical in situations involving signs of severe allergic reactions. Prompt response can ensure that the patient receives the necessary evaluation and treatment to prevent further complications.

In contrast, continuing the medication could exacerbate the reaction; using antihistamines may not be effective against angioedema, and adjusting the dose without medical guidance could be unsafe. Therefore, seeking medical attention is the most appropriate course of action for patients experiencing such symptoms.
