Morphine (for breathlessness)

mor-feen

What does it do?

Morphine is used to reduce breathlessness and cough.

For information on morphine for pain relief see Morphine (long acting) or Morphine (short acting).

Before you start

  • Tell your doctor if you have bowel or kidney problems, sleep apnoea, if you have ever had a seizure, or have had a recent head injury.
  • Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take morphine as directed with a glass of non-alcoholic drink. You can take it with or without food.
Liquid: Measure carefully with an oral syringe or measuring spoon. Leave at least four hours between doses. It takes at least 20 minutes to start working. Try taking it before activities that you know make you breathless like showering, or before you go out.
Slow-release tablet or capsule: Swallow whole – do not crush or chew.

Your dose is: ____________________________________________ Date: __________________

What if you forget a dose?

If you are taking morphine regularly for your breathlessness, and it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take the missed dose as soon as you remember. Do not take two doses at the same time.

If you are only taking it when you need it for breathlessness, then you don't need to take it.

Can you take other medicines?

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.

Other information:

  • The small amount of morphine used to treat breathlessness isn't likely to cause addiction if you haven't had problems with addiction before.
  • Morphine can impair your ability to do tasks such as driving or using machines. Alcohol makes this worse. Discuss your risk with your health professional. (search NZTA - Are you safe to drive?)
