Title: Features and overview

Context:
Rapid Taper is done over days. Rapid tapers can cause withdrawal effects and patients should be treated with adjunctive medications to minimize these effects; may need to consider admitting the patient for inpatient care. If patients are prescribed both long-acting and short-acting opioids, the decision about which formulation to be tapered first should be individualized based on medical history, mental health diagnoses, and patient preference. Data shows that overdose risk is greater with long-acting preparations. In rapid taper, reduce opioid by 20 to 50% of first dose if needed, then reduce by 10 to 20% every day. An example of the rapid taper is given below. During the first day in the rapid taper, 33% reduction of morphine SR 90 mg Q8h = 270 MEDD consists of 60 mg SR (15 mg x 4) Q8h. The subsequent daily dosage for the rapid taper is 45 mg SR (15 mg x 3) Q8h for day 2, 30 mg SR (15 mg x 2) Q8h for day 3, 15 mg SR Q8h for day 4, 15 mg SR Q12h for day 5-7, 15 mg SR QHS for day 8-11. Stop rapid tapering after day 11 and may consider morphine IR 15 mg ½ tablet (7.5 mg) twice daily.

Question: When reducing 33% of morphine SR 90 mg Q8h = 270 MEDD on day 1, what dose should be taken on day four of the rapid opioid tapering?

Answer: 15 mg SR Q8h
