INOTROPES AND VASOPRESSORS AND MAOIS - METARAMINOL OR PHENYLEPHRINE

Metaraminol and phenylephrine are vasopressors with both direct and indirect sympathomimetic actions. This means that it may cause serious and potentially fatal hypertensive reactions in patients taking MAOIs.
Avoid the use of metaraminol or phenylephrine in patients who are either taking MAOIs or who have stopped taking them in the previous 2 weeks.
