Zuclopenthixol decanoate induced dysphagia.

Dysphagia, a well-recognised adverse effect in many different antipsychotics, is not a formally acknowledged side effect in zuclopenthixol. This case report describes a patient with known bipolar affective disorder who had been recently stabilised on zuclopenthixol decanoate and presented with sudden onset severe oropharyngeal dysphagia. Symptoms spontaneously resolved with the discontinuation of the medication, and this report explores the suggested underlying mechanisms from literature.
