Fetal hydrothorax, chylothorax, or large pleural effusion associated with bronchopulmonary sequestration should be treated using a Fetal needle drainage of effusion or placement of thoracoamniotic shunt. This procedure can be performed prior to delivery if gestational age is advanced. Hydrops Fetalis resulting from fetal CPAM can be treated using either a fetal needle drainage of effusion or placement of thoracoamniotic shunt or a maternal administration of corticosteroids, betamethasone 12.5 mg IM q24 h × 2 doses or dexamethasone 6.25 mg IM q12 h × 4 doses. Therapy for hydrops fetalis derived from TTTS or TAPS requires laser ablation of placental anastomoses or selective termination. Therapy for hydrops fetalis derived from TRAPS requires percutaneous radio frequency ablation. See also

This meta-analysis also found that asenapine has approximately the same odds ratio (3.28; 95% CI: 1.37-6.69) for causing sedation [compared to placebo-treated patients] as olanzapine (3.34; 95% CI: 2.46-4.50]) and haloperidol (2.76; 95% CI: 2.04-3.66) and a higher odds ratio (although not significantly) for sedation than aripiprazole (1.84; 95% CI: 1.05-3.05), paliperidone (1.40; 95% CI: 0.85-2.19) and amisulpride (1.42; 95% CI: 0.72 to 2.51) to name a few and is hence a mild-moderately sedating antipsychotic. The same meta-analysis suggested that asenapine had a relatively high risk of extrapyramidal symptoms compared to other atypical antipsychotics but a lower risk than first-generation or typical antipsychotics. Discontinuation
For all antipsychotics, the British National Formulary recommends a gradual dose reduction when discontinuing to avoid acute withdrawal syndrome or rapid relapse. Symptoms of withdrawal commonly include nausea, vomiting, and loss of appetite. Other symptoms may include restlessness, increased sweating, and trouble sleeping. Less commonly there may be a feeling of the world spinning, numbness, or muscle pains. Symptoms generally resolve after a short period of time.There is tentative evidence that discontinuation of antipsychotics can result in psychosis. It may also result in recurrence of the condition that is being treated. Rarely tardive dyskinesia can occur when the medication is stopped.
