Adult Cocaine Overdose presenting with SVT, wide complex tachycardia, hypertension, seizure: which medication is contraindicated in hypotension?

• A. Versed
• B. Ketamine
• C. Fentanyl
• D. Nitroglycerin

Answer: (A)

In cocaine overdose, treatment aims to calm the central sympathetic surge with sedatives, but the patient’s blood pressure status must guide which drugs you use. Midazolam can cause vasodilation and decreased systemic vascular resistance, which can further drop blood pressure. When hypotension is present, this additional BP drop makes a benzodiazepine like midazolam contraindicated, because it can worsen perfusion to vital organs. The other options interact with blood pressure differently: ketamine tends to raise blood pressure and heart rate, so it’s less likely to worsen hypotension; fentanyl can cause some BP drop but is not as strongly hypotensive as a benzodiazepine in this context; nitroglycerin would also lower BP as a vasodilator, which would be problematic in hypotension, but the key teaching point here is that the sedative that most clearly risks dangerous BP decrease in a hypotensive cocaine-toxic patient is midazolam.
