The patient’s treatment included fluvoxamine at a dosage that was increased to 300 mg/day, carbamazepine 200mg twice daily, zuclopenthixol, temazepam and procyclidine. A few days after he started the full dose of fluvoxamine and several weeks after he started carbamazepine therapy, he developed pitting oedema from his ankle to his mid-calf. In addition, he became acutely breathless after minimal exertion. A few days later, the man developed a left-sided weakness with paraesthesia and drooping of the left side of his face.

Further examination revealed that the man had impaired sensation to light touch and pin-prick over the left side of his face and leg. He found it difficult to walk.
