For Healthcare Professionals
Applies to thiothixene: intramuscular powder for injection, oral capsule, oral concentrate
Nervous system side effects are common and include drowsiness, dystonia, akathisia, and other extrapyramidal effects in up to 46% of treated patients. Patients with renal insufficiency may be particularly prone to the extrapyramidal effects of thiothixene (the active ingredient contained in Navane)
Akathisia has been reported in up to 20% of patients receiving a single dose of thiothixene and 63% of patients receiving chronic treatment. Laryngeal-pharyngeal dystonia has also been reported rarely. In some cases, dystonia has been associated with rhabdomyolysis leading to acute renal failure.
Treatment of dystonic reactions and extrapyramidal effects, in addition to general supportive measures, may include judicious use of one or more of the following: benztropine, trihexyphenidyl, biperiden, or diphenhydramine.
Other side effects including tardive dyskinesia have been reported and may be irreversible. Neuroleptic malignant syndrome has been reported to occur in as many as 0.5% to 1.0% of patients taking neuroleptic agents. Thiothixene has been specifically implicated. Sudden death after parenteral administration of thiothixene (the active ingredient contained in Navane) has been rarely reported in patients without underlying medical illness.
Involuntary rhythmical movements of the tongue, face and mouth characterize tardive dyskinesia. Early recognition of premonitory symptoms of tardive dyskinesia (like hyperkinetic dysarthria and fine vermiform movements of the tongue) may allow discontinuation of thiothixene before irreversible dyskinesia ensues. Tardive dyskinesia has been reported to occur in patients taking as little as 5 mg of thiothixene daily for eight months.
Fever, altered consciousness, autonomic dysfunction and muscle rigidity are the hallmarks of the neuroleptic malignant syndrome. The neuroleptic malignant syndrome is associated with a case fatality rate of about 20%. Immediate discontinuation of neuroleptic therapy and intensive monitoring and supportive care are indicated.
The anticholinergic effects of thiothixene (the active ingredient contained in Navane) have been implicated as a cause of esophageal atony and esophageal dilatation in one patient. That patient was also taking benztropine. The esophageal atony and dilatation resolved after dose reductions.
Gastrointestinal side effects including nausea, vomiting, constipation, excessive salivation, and dry mouth have been reported.
Psychiatric side effects have included bizarre nightmares involving torture, worsening of underlying psychiatric illness, and agitation.
Endocrine side effects including hyperprolactinemia, galactorrhea, amenorrhea, and (less frequently) hyponatremia have been reported.
Ocular side effects including pigmentary retinopathy and lenticular pigmentation have been reported.
Some clinicians have recommended periodic slit lamp examination for patients on chronic thiothixene therapy.
Hematologic side effects including cases of reversible thrombocytopenia and leukopenia have been reported rarely.
Genitourinary side effects including priapism, urinary incontinence, nocturnal enuresis, and spontaneous ejaculation have been reported.
Immunologic side effects including Raynaud's phenomenon and a lupus-like syndrome have been reported.
Cardiovascular side effects including nonspecific EKG changes of uncertain clinical significance, orthostatic hypotension, tachycardia, and syncope have been reported.
Hypersensitivity side effects including a telangiectatic macular eruption of the palms has been reported. Thiothixene (the active ingredient contained in Navane) may also predispose patients to photosensitivity.
Oncologic side effects including endometrial adenocarcinoma have been reported in association with thiothixene (the active ingredient contained in Navane) induced hyperprolactinemia.
Some investigators have suggested that endometrial sampling be performed in women taking neuroleptics if warranted by clinical suspicion.
