Which of the following is not a symptom of Pethidine overdose?

• A. Hypotension
• B. Respiratory depression
• C. Pinpoint pupils
• D. Tinnitus

Answer: (D)

Pethidine, also known as meperidine, is an opioid analgesic used to relieve moderate to severe pain. Like other opioids, an overdose can lead to several distinctive symptoms due to its central nervous system effects. Hypotension, respiratory depression, and pinpoint pupils are classic signs of opioid overdose. Hypotension refers to abnormally low blood pressure, which can occur due to vasodilation and central nervous system depressant effects of opioids. Respiratory depression is one of the most serious and critical symptoms of opioid overdose, characterized by slowed or difficulty breathing. Pinpoint pupils, or miosis, are often observed in opioid overdose, where the pupils constrict to a very small size. Tinnitus, or ringing in the ears, is not typically associated with pethidine overdose. While tinnitus can be a side effect of various medications or conditions, it is not a hallmark symptom of opioid toxicity. Therefore, this makes tinnitus the correct response to the question posed, as it does not align with the known symptoms of pethidine overdose.
