Difficult Conversations and Decisions about prescribing drugs of dependence

We are working at a time of evolving evidence of benefits and harms, and changing community and professional expectations, around appropriate prescribing of drugs of dependence. These expectations are often cloudy, confusing and conflicting, and there can be long waits for specialist support.

It helps us to have a clear approach in making decisions about prescribing drugs of dependence, and then to be able to be clear in our communication about our decisions. For what it is worth, some aspects of my approach follow:

When considering prescribing drugs of dependence:

  • Be clear about your indications for prescribing specific medications (especially for opioid and benzodiazepine medications).
  • Be clear about your preferred management of relevant presenting conditions (especially for persistent anxiety or pain conditions).
  • Have a conversation about the presenting problem rather than a medication.
  • Only prescribe a medication if it is indicated in your opinion for the presenting problem.

If it is appropriate to decline a request for a drug of dependence, be clear about why: “In my clinical opinion that is not a good medication for your problem, and I don’t prescribe it for that purpose”. “The problem with opioid medications for chronic back pain is that as your body gets used to them they stop working. You need to increase the dose to have the same effect; and then they can be very hard to stop”.
If an individual is already taking a drug of dependence regularly, it can be difficult to stop. Attempts at reduction can result in withdrawal symptoms which may include increased pain or anxiety, and the individual may be very fearful of this experience. It may be reasonable to continue prescribing of drugs of dependence, especially in situations of good effect and low risk.

Some associated risks can be reduced with some structures such as:

  • One doctor, one pharmacy, one benzodiazepine, one opioid medication.
  • Regular collection of medication from pharmacy (fortnightly, weekly, twice weekly, daily).
  • Rotation to a longer acting medication (such as buprenorphine) to avoid contribution of withdrawal symptoms to pain or anxiety.
  • Checking Safescript.
