In the absence of data in patients with severe renal impairment (CrCl <10 ml / min), amisulpride is contraindicated (see contraindications).
- Hepatic insufficiency :
Since amisulpride is weakly metabolized, dosage reduction is not necessary in patients with hepatic impairment.
This medicine MUST NOT BE USED in the following cases:
- Known hypersensitivity to amisulpride or any other constituent of the product.
Serious hypertensive events have been reported in patients with pheochromocytoma with anti-dopaminergic drugs including some benzamides. It is therefore prudent to refrain from prescribing this product in known or suspected carriers of pheochromocytoma.

The frequency of extrapyramidal symptoms that are dose-dependent, is very low in patients receiving doses between 50 and 300 mg / d in the treatment of predominant deficit symptoms.

. gastrointestinal disorders such as constipation, nausea, vomiting, dryness of the mouth.

. Acute dystonia (spasmodic torticollis, oculogyric crises, trismus ...) may appear. It is reversible without stopping treatment under the effect of antiparkinsonian anticholinergic.

Antiparkinsonian anti-cholinergic drugs have no action or can cause aggravation.
. Cases of hypotension and bradycardia.
. Cases of prolongation of the QT interval, and very rare cases of torsades de pointes have been reported (see warnings and precautions for use).
. Allergic reactions.
. Cases of seizures.
. Cases of malignant syndrome (see warnings and precautions for use: hyperthermia, muscle rigidity, neurovegetative disorders, impaired consciousness, increased CPK).
