A patient who has parkinsonism will begin taking carbidopa-levodopa. What information will the nurse include when teaching this patient about this medication?
a. "Call your health care provider immediately if your urine or perspiration turn a dark color."
b. "Rise slowly from your bed or your chair to avoid dizziness and falls."
c. "Take the drug with foods high in protein to improve drug delivery."
d. "Discontinue the drug if you experience insomnia."
ANS: B
Carbidopa-levodopa can cause orthostatic hypotension, so patients should be taught to take care when getting out of bed or a chair. Darkening of the urine and perspiration is a harmless side effect. Patients should take the drug with low-protein foods to improve drug transport to the CNS. Carbidopa-levodopa should not be discontinued abruptly because rebound parkinsonism may occur; insomnia is an expected adverse effect of the drug, and the patient should report this effect to his or her health care provider.
