Usual max: 60mcg. Neurogenic etiology: initially 1.25mcg; if partial response, may increase dose to 2.5mcg within 1hr; during titration: max 2 doses within 24hr period; if more titration is needed, may give 5mcg during the next 24hrs; thereafter, may give doses in increments of 5mcg at least 24hrs apart until optimal dose is achieved. Usual max: 60mcg. Maintenance for home use: max 3 injections/week; allow at least 24hrs between doses. Adjunct in diagnosis: see full labeling.
