After 4 wk, continue oral antidepressant therapy per clinical judgment.

Hypersensitivity to esketamine or ketamine. Patients for whom an increase in BP or ICP poses a serious risk eg, those w/ known aneurysmal vascular disease (including intracranial, thoracic or abdominal aorta, or peripheral arterial vessels) or history of intracerebral hemorrhage.

For nasal use only. Effectiveness in preventing suicide or reducing suicidal ideation or behavior has not been demonstrated. Does not preclude need for hospitalization if clinically warranted even if patients experience improvement after initial dose. Closely monitor patients for clinical worsening or emergence of suicidal thoughts & behaviors, especially during initial few mth of therapy & at times of dosage changes. Greater risk of suicidal thoughts or attempts in patients w/ history of suicide related events or those exhibiting a significant degree of suicidal ideation prior to commencement of treatment. Carefully assess patients w/ CV & cerebrovascular conditions prior to prescribing including those w/ unstable or poorly controlled HTN, history (w/in 6 wk) of CV event including MI, history (w/in 6 mth) of ischemic stroke or transient ischemic attack, hemodynamically significant valvular heart disease (eg, mitral regurgitation, aortic stenosis or aortic regurgitation), NYHA class III-IV heart failure of any etiology. Administration can temporarily raise BP lasting approx 1-2 hr; assess BP prior to dosing. Closely monitor BP in concomitant use w/ psychostimulants or MAOIs. Potential for cognitive (short- & long-term) & motor impairment. Patients w/ history of drug abuse or dependence; substance use disorder including alcohol; presence or history of psychosis, mania or bipolar disorder; hyperthyroidism that has not been sufficiently treated; significant pulmonary insufficiency; known uncontrolled brady or tachyarrhythmias that lead to hemodynamic instability; history of brain injury, hypertensive encephalopathy, intrathecal therapy w/ ventricular shunts, or any other condition associated w/ increased ICP. Advise patients not to eat for at least 2 hr & not to drink liqd at least 30 min prior to administration. Monitor patients for resp depression. Do not engage in potentially hazardous activities requiring complete mental alertness & motor coordination (eg, driving motor vehicle or operating machinery) until the next day following a restful sleep.

Increased mean C_max & AUC_∞ w/ oral clarithromycin. Decreased mean C_max & AUC_∞ w/ oral rifampicin. Minor pharmacokinetic effects w/ other nasal spray products (eg, oxymetazoline & mometasone furoate). Reduced mean plasma AUC_∞ of oral midazolam.
