Question

Pt. has h/o vomiting & doctor gave antiemetic. Patient developed abnormal movements. What would be given

• A. Methyl dopa
• B. Benzhexol
• C. Hyoscine
• D. Cyproheptadine

Answer 1

The Correct Option is B

The patient was given an antiemetic and subsequently developed abnormal movements. This scenario suggests that the prescribed antiemetic is likely a dopamine antagonist, such as metoclopramide or prochlorperazine, which are known to cause extrapyramidal side effects (EPS) like abnormal movements or drug-induced parkinsonism due to dopamine receptor blockade.

To manage these symptoms, an anticholinergic medication is typically administered, as it helps to rebalance the neurotransmitters in the brain by counteracting the effects of dopamine antagonists. Benzhexol, also known as trihexyphenidyl, is an anticholinergic agent often used to treat drug-induced parkinsonism or EPS.

Therefore, in this scenario, the appropriate medication to give is Benzhexol.

Option	Type	Use in Scenario
Methyl dopa	Antihypertensive	Not applicable for EPS
Benzhexol	Anticholinergic	Used for EPS
Hyoscine	Antimuscarinic	Not used for EPS
Cyproheptadine	Antihistamine/Serotonin antagonist	Not used for EPS

Hence, Benzhexol is chosen to alleviate the abnormal movements caused by the antiemetic treatment.
