एम्फेटामाइन और फेनेलज़िन का इंटरैक्शन

The potentiation of sympathomimetic substances and related compounds by MAO inhibitors may result in hypertensive crises (see WARNINGS ).

Therefore, patients being treated with phenelzine sulfate should not take sympathomimetic drugs (including amphetamines, cocaine, methylphenidate, dopamine, epinephrine, and norepinephrine) or related compounds (including methyldopa, L-dopa, L-tryptophan, L-tyrosine, and phenylalanine).

Also, they should not be given cocaine or local anesthesia containing sympathomimetic vasoconstrictors.

Patients taking monoamine oxidase inhibitors (MAOIs), or within 14 days of stopping MAOIs (including MAOIs such as linezolid or intravenous methylene blue), because of an increased risk of hypertensive crisis [ see Warnings and Precautions (5.7) , Drug Interactions (7.1) ].

Use of monoamine oxidase inhibitor (MAOI) or within 14 days of the last MAOI dose ( 4 , 7.1 )

Serotonin Syndrome: Increased risk when co-administered with serotonergic agents (e.g., SSRIs, SNRIs, triptans), but also during overdosage situations.

Concomitant use of DYANAVEL XR with MAOI drugs is contraindicated [ see Contraindications (4) ] .

Discontinue treatment with DYANAVEL XR and any concomitant serotonergic agents immediately if symptoms of serotonin syndrome occur, and initiate supportive symptomatic treatment.
