From the Guidelines
To taper a patient off morphine MSIR 15mg BID when 15mg is the lowest manufactured dose, I recommend implementing a gradual reduction schedule using pill splitting or liquid formulation, as suggested by the CDC clinical practice guideline for prescribing opioids for pain - United States, 2022 1. When considering tapering, it's crucial to weigh the benefits and risks of continuing opioid therapy versus tapering, and to involve the patient in the decision-making process.
Key Considerations
- The patient's agreement and interest in tapering are key components of a successful taper 1.
- A taper slow enough to minimize symptoms and signs of opioid withdrawal should be used, with longer durations of previous opioid therapy potentially requiring longer tapers 1.
- For patients who have taken opioids long-term, tapers of 10% per month or slower are likely to be better tolerated than more rapid tapers 1.
Tapering Schedule
Start by reducing to 15mg in the morning and 7.5mg (half tablet) in the evening for 3-7 days, then 7.5mg twice daily for 3-7 days, followed by 7.5mg once daily for 3-7 days before discontinuing completely. If pill splitting is not feasible, consider switching to morphine oral solution (20mg/mL or 10mg/5mL), which allows for more precise dose reductions. For example, reduce to 10mg BID for 3-7 days, then 5mg BID for 3-7 days, then 5mg once daily before stopping.
Monitoring and Support
Throughout the taper, monitor for withdrawal symptoms such as anxiety, irritability, muscle aches, insomnia, and gastrointestinal distress. Adjunctive medications like clonidine, NSAIDs, or antiemetics may help manage these symptoms 1. The gradual taper is essential because abrupt discontinuation of opioids can lead to withdrawal syndrome due to neuroadaptation and receptor downregulation that occurs with chronic opioid use. The body needs time to readjust to functioning without the opioid, and a slow taper minimizes the severity of withdrawal symptoms while allowing physiological readaptation.
Additional Guidance
The CDC guideline also recommends that clinicians follow up frequently (at least monthly) with patients engaging in opioid tapering, and that team members can support the clinician and patient during the ongoing taper process through telephone contact, telehealth visits, or face-to-face visits 1. Clinicians should remain alert to signs of and screen for anxiety, depression, and opioid misuse or opioid use disorder that might be revealed by an opioid taper, and provide treatment or arrange for management of these comorbidities 1.
From the FDA Drug Label
When a decision has been made to decrease the dose or discontinue therapy in an opioid-dependent patient taking morphine sulfate tablets, there are a variety of factors that should be considered, including the dose of morphine sulfate tablets the patient has been taking, the duration of treatment, the type of pain being treated, and the physical and psychological attributes of the patient For patients on morphine sulfate tablets who are physically opioid-dependent, initiate the taper by a small enough increment (e.g., no greater than 10% to 25% of the total daily dose) to avoid withdrawal symptoms, and proceed with dose-lowering at an interval of every 2 to 4 weeks. It may be necessary to provide the patient with lower dosage strengths to accomplish a successful taper
To taper a patient off morphine MSIR 15mg BID, initiate the taper by reducing the dose by 10% to 25% of the total daily dose, which is 30mg in this case. This would be a reduction of 3mg to 7.5mg per day. Since the lowest available dose is 15mg, alternative formulations or doses may be needed to accomplish a successful taper. The taper should be done gradually, with dose-lowering at an interval of every 2 to 4 weeks, and the patient should be frequently reassessed to manage pain and withdrawal symptoms 2.
From the Research
Tapering Morphine MSIR 15mg BID
To taper a patient off morphine MSIR 15mg BID when 15mg is the lowest dose made, consider the following steps:
- Gradually reduce the dose by the smallest possible amount to minimize withdrawal symptoms
- Monitor the patient's response to the dose reduction and adjust the tapering schedule as needed
- Consider alternative pain management options, such as non-opioid analgesics or adjuvant therapies, to support the patient during the tapering process
Alternative Pain Management Options
Some studies suggest that combining morphine with other medications, such as gabapentin 3 or pregabalin 4, 5, may enhance its analgesic effect and allow for lower doses of morphine to be used. However, these combinations should be used with caution and under close medical supervision.
Considerations for Tapering
When tapering a patient off morphine, it is essential to consider the potential for withdrawal symptoms, such as anxiety, insomnia, and restlessness. A gradual tapering schedule can help minimize these symptoms. Additionally, the patient's individual needs and medical history should be taken into account when developing a tapering plan.
Lack of Direct Evidence
There is no direct evidence in the provided studies to support a specific tapering schedule for morphine MSIR 15mg BID. However, the studies suggest that combining morphine with other medications or using alternative pain management options may be effective in reducing the dose of morphine required for pain management 3, 4, 5.
