A patient who has been taking verapamil [Calan] for hypertension complains of constipation. The patient will begin taking amlodipine [Norvasc] to avoid this side effect. The nurse provides teaching about the difference between the two drugs
Which statement by the patient indicates that further teaching is needed? a. "I can expect dizziness and facial flushing with nifedipine."
b. "I should notify the provider if I have swelling of my hands and feet."
c. "I will need to take a beta blocker to pre-vent reflex tachycardia."
d. "I will need to take this drug once a day."
C
Amlodipine produces selective blockade of calcium channels in blood vessels with minimal ef-fects on the heart. Reflex tachycardia is not common, so a beta blocker is not indicated to prevent this effect. Dizziness and facial flushing may occur. Peripheral edema may occur and should be reported to the provider. Amlodipine is given once daily.
