MONITOR: Agents that increase blood pressure such as vasopressors, triptans, decongestants, beta-2 agonists, and amphetamines may potentiate the risk of supine hypertension associated with the use of droxidopa in the treatment of neurogenic orthostatic hypotension.
MANAGEMENT: Supine blood pressure should be monitored prior to and during droxidopa treatment, and more frequently when increasing dosage. Patients should elevate the head of the bed when resting or sleeping, and have blood pressure also measured in this position. Dosage reduction or discontinuation of droxidopa is recommended if supine hypertension cannot be managed by elevation of the head of the bed. Supine hypertension that is not well managed may increase the risk of cardiovascular events, particularly stroke.

GENERALLY AVOID: Use of anticholinergic agents with alcohol may result in sufficient impairment of attention so as to render driving and operating machinery more hazardous. In addition, the potential for abuse may be increased with the combination. The mechanism of interaction is not established but may involve additive depressant effects on the central nervous system. No effect of oral propantheline or atropine on blood alcohol levels was observed in healthy volunteers when administered before ingestion of a standard ethanol load. However, one study found impairment of attention in subjects given atropine 0.5 mg or glycopyrrolate 1 mg in combination with alcohol.
MANAGEMENT: Alcohol should generally be avoided during therapy with anticholinergic agents. Patients should be counseled to avoid activities requiring mental alertness until they know how these agents affect them.
