Diagnosis
- When offering pain treatment with strong opioids to a patient with advanced and progressive disease, ask them about concerns such as:
- Addiction
- Tolerance
- Side effects
- Fears that treatment implies the final stages of life
- Provide verbal and written information on strong opioid treatment to patients and carers including:
- When and why strong opioids are used to treat pain
- How effective they are likely to be
- Taking strong opioids for background and breakthrough pain, addressing: how, when and how often to take strong opioids & how long pain relief should last
- Side effects and signs of toxicity
- Safe storage
- Follow-up and further prescribing
Investigation
Management
Starting Strong Opioids - Titrating the Dose:
- Regular oral sustained-release or oral immediate-release morphine (patient preference) with rescue doses of oral immediate-release morphine for breakthrough pain
- Renal or hepatic comorbidities, offer a total daily starting dose of 20–30 mg of oral morphine (i.e. 10-15 mg sustained release BD) + 5 mg immediate release PRN
- Adjust the dose until a good balance exists between acceptable pain control and side effects
First Line Maintenance:
- Oral sustained-release morphine
- If oral opioids are not suitable (consider with specialist advice):
- Transdermal patch formulations but not routinely
- Subcutaneous morphine
First Line Breakthrough Pain:
- Oral immediate-release morphine
- Do not offer fast-acting fentanyl, if pain remains inadequately controlled despite optimising treatment, consider seeking specialist advice
Management of constipation
- Prescribe laxative treatment regularly at an effective dose, advise takes time to work and adherence important
Management of nausea
- advise likely transient, if persists prescribe and optimise anti-emetic treatment before considering switching strong opioids
Management of drowsiness
- consider dose reduction if pain is controlled or consider switching opioids if pain, specialist advice if continues
