• 
B/P, pulse, respirations during beginning therapy; notify prescriber if pulse <50 bpm or systolic B/P <90 mm Hg

 
ECG
continuously if using as antidysrhythmic IV, PCWP (pulmonary capillary wedge pressure), CVP (central venous pressure)

• 
Hepatic enzymes: AST, ALT, bilirubin

• 
Angina pain: duration, time started, activity being performed, character

• 
Tolerance with long-term use

• 
Headache, lightheadedness, decreased B/P; may indicate need for decreased dosage; may aggrevate symptoms of arterial insufficiency

• 
Protection from light

Evaluate:

• 
Therapeutic response: decreased B/P, dysrhythmias

Teach patient/family:

 
Not to discontinue abruptly; may precipitate life-threatening dysrhythmias, exacerbation of angina, MI; to take product at same time each day, either with or without food consistently; to decrease dosage over 2 wk

• 
To avoid OTC products unless approved by prescriber; to avoid alcohol
