Can I use Avinza if I have a mental illness?

You can take the painkiller Avinza (morphine) if you have a mental illness, as long as you are not treating your mental condition with a medication that dangerously interacts with it. You shouldn't take Avinza if you use an antidepressant known as a monoamine oxidase inhibitor (MAOI), such as tranylcypromine (Parnate), phenelzine (Nardil), selegiline (Emsam, Eldepryl), procarbazine (Matulane) or isocarboxazid (Marplan). In fact, you shouldn't take Avinza until at least two weeks have passed since your last dose of an MAOI. These drugs increase Avinza's potency, which can cause severe side effects and even a fatal overdose.

So your doctor can decide if Avinza is safe for you, and at what dose, you should also tell your doctor if you take any of the following drugs:

  • tranquilizers, sedatives, barbiturates or sleeping pills
  • muscle relaxers
  • street drugs
  • antipsychotics
  • tricyclic antidepressants, such as amitriptyline, amoxapine (Asendin), clomipramine (Anafranil), desipramine (Norpramin), doxepin (Adapin, Sinequan), imipramine (Tofranil), nortriptyline (Aventyl, Pamelor), protriptyline (Vivactil) and trimipramine (Surmontil)
  • antiseizure drugs
