Orofacial dyskinesia associated with tiemonium.

Tiemonium, an anti-spasmodic drug, can have adverse effects related to its anti-muscarinic effect. Dyskinesia is described with other anti-cholinergic drugs, but there are no reports of dyskinesia associated with tiemonium. We report a reversible orofacial dyskinesia following tiemonium intake (contained in Viscéralgine forte) in a woman with positive rechallenge. She presented these symptoms two times after two separate injections with an interval of 2 months. The case was reported to the Tunisian Centre of Pharmacovigilance.
