Opium tincture contains morphine. Morphine should be avoided in patients treated with monoamine oxidase inhibitors (MAOI) due to enhance toxicity of morphine including confusion, high blood pressure, tremor, hyperactivity, coma, and death. Drugs in this class include isocarboxazid (Marplan), phenelzine (Nardil), tranylcypromine (Parnate), selegiline (Eldepryl), and procarbazine (Matulane), and linezolid (Zyvox). Morphine should not be administered within 14 days of stopping an MAOI.
