Long-Term Effects

Cautions
- Tardive dyskinesia, a syndrome consisting of potentially irreversible, involuntary, dyskinetic movements, may develop in patients treated with antipsychotic drugs; if signs and symptoms of tardive dyskinesia appear in patients on antipsychotics, consider drug discontinuation; however, some patients may require treatment despite presence of the syndrome
- May cause drowsiness, postural hypotension, motor instability, and sensory instability, which may lead to falls and, consequently, fractures or other injuries; complete fall-risk assessments for patients with diseases, conditions, or medications that could exacerbate these effects, when initiating antipsychotic treatment and recurrently for patients on long-term antipsychotic therapy
- Neuroleptic malignant syndrome (NMS) reported with antipsychotic drug use; immediately discontinue therapy if it occurs along with nonessential concurrent therapy and administer intensive symptomatic treatment and monitor carefully; if the patient requires antipsychotic drug treatment after recovery from NMS, it should be considered carefully, and the patient should be monitored closely because recurrences of NMS have been reported
- May cause drowsiness initially; advise the patient against activities requiring mental alertness until response to the drug has been established
- Convulsive seizures reported with the use
- The preparation contains calcium sulfate as an excipient; calcium ions may interfere with the absorption of preparations containing phenytoin sodium and tetracyclines
- Therapy may obscure signs of intestinal obstruction or brain tumor
- Antipsychotic drugs elevate prolactin levels; elevation persists during long-term administration; although disturbances such as galactorrhea, amenorrhea, gynecomastia, and impotence have been reported, the clinical significance of elevated serum prolactin levels are unknown for most patients
- Therapy has not been effective in the management of behavioral complications in patients with mental retardation
- In clinical trial and/or postmarketing experience, events of leukopenia/neutropenia and agranulocytosis have been reported temporally related to antipsychotic agents; possible risk factors for leukopenia/neutropenia include preexisting low white blood cell (WBC) count and history of drug-induced leukopenia/neutropenia; patients with clinically significant neutropenia should be carefully monitored for fever or other symptoms or signs of infection and treated promptly if such symptoms or signs occur; patients with severe neutropenia (absolute neutrophil count less than 1000/mm3) should discontinue therapy and have their WBC count followed until recovery
Pregnancy and Lactation
- Studies in pregnant women have not been performed; animal reproductive studies have not demonstrated a teratogenic potential; anticipated benefits must be weighed against unknown risks to the fetus if used in pregnant women
- Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at a risk for extrapyramidal and/or withdrawal symptoms following delivery; agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorders reported in neonates; complications have varied in severity; while in some cases symptoms have been self-limited, in other cases, neonates have required intensive care unit support and prolonged hospitalization
- Lactation
- Data are not available on the content of molindone hydrochloride in the milk of nursing mothers
