Answer Choices:
Correct Answer:
"Your doctor might need to reduce your theophylline dose while taking this medication."
Rationale:
♦ Mechanism: Cimetidine inhibits cytochrome P450 enzymes, affecting metabolism of several drugs including theophylline, warfarin, and phenytoin.
♦ Clinical Importance: Concurrent use increases plasma concentrations, risking toxicity.
♦ Teaching: Advise clients to report signs of theophylline toxicity—nausea, tremor, restlessness, or tachycardia.
♦ Administration Tip: Take with meals or at bedtime, not with antacids, to avoid interference with absorption.
♦ Duration: Usually prescribed for 4–6 weeks, not months, unless clinically indicated.
