Which condition is a relative contraindication to midazolam use?

• A. History of allergy to penicillin
• B. Diabetes mellitus without complications
• C. Hypersensitivity to benzodiazepines
• D. Controlled hypertension

Answer: (C)

The main concept is drug allergy to a class of medications guiding sedation choices. Midazolam is a benzodiazepine, and if a patient has hypersensitivity to benzodiazepines, giving midazolam could provoke a serious allergic reaction. Cross-reactivity within the benzodiazepine class means a prior benzodiazepine allergy raises the risk with any drug in that class, so midazolam should be avoided. That’s why hypersensitivity to benzodiazepines is the best answer. The other conditions—penicillin allergy, diabetes without complications, and controlled hypertension—do not involve the benzodiazepine class and do not by themselves contraindicate midazolam.
