Naloxone may also be given by continuous intravenous infusion, 2 mg diluted in ml, at a rate adjusted to the patient’s response. This might be in your thigh, stomach or upper arm. Thereafter, the dose should be adjusted with careful assessment of the pain, and the use of adjuvant analgesics should also be considered. The general principle that injections should be given into separate sites and should not be mixed does not apply to the use of syringe drivers in palliative care. Abrupt withdrawal in patients who have developed dependence may precipitate a withdrawal syndrome. Glucose intravenous infusion is the preferred diluent, particularly when the drug is administered by a continuous infusion pump over 24 to 48 hours, although it is also compatible with sodium chloride intravenous infusion.

Gastric distension pain due to pressure on the stomach may be helped by a preparation incorporating an antacid with an antiflatulent and a prokinetic such as domperidone before meals. The infusion is discontinued when the first oral dose of morphine is given. Upward titration of the dose of morphine stops when either the pain is relieved or unacceptable adverse effects occur, after which it is necessary to consider alternative measures.
