Dosage and Instructions

Important Recommendations Prior to Initiating IGALMI and During Therapy 

IGALMI should be administered under the supervision of a healthcare provider. A healthcare provider should monitor vital signs and alertness after IGALMI administration to prevent falls and syncope.

IGALMI is for sublingual or buccal administration. Do not chew or swallow IGALMI. Do not eat or drink for at least 15 minutes after sublingual administration, or at least one hour after buccal administration.

Recommended Dosage 

Table 1 includes dosage recommendations for IGALMI based on agitation severity for adults, patients with hepatic impairment, and geriatric patients. Lower dosages are recommended for patients with hepatic impairment and geriatric patients.

If agitation persists after the initial dose, up to two additional doses may be administered at least two hours apart. The dosage recommendations for additional doses vary depending upon the patient population and agitation severity (see Table 1). Assess vital signs including orthostatic measurements prior to the administration of any subsequent doses.

Due to risk of hypotension, additional half-doses are not recommended in patients with systolic blood pressure (SBP) less than 90 mmHg, diastolic blood pressure (DBP) less than 60 mmHg, heart rate (HR) less than 60 beats per minute, or postural decrease in SBP ≥ 20 mmHg or in DBP ≥ 10 mmHg.
