Antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, and young adults.
PARNATE should not be administered in combination with any SSRI or SNRI. There have been reports of serious, sometimes fatal, reactions (including hyperthermia, rigidity, myoclonus, autonomic instability with possible rapid fluctuations of vital signs, and mental status changes that include extreme agitation progressing to delirium and coma) in patients receiving a SSRI (e.g., fluoxetine, Prozac®) or a SNRI (e.g., venlafaxine, Effexor®, Effexor XR®, Wyeth) in combination with a monoamine oxidase inhibitor.
PARNATE should not be used in combination with buspirone HCl, since several cases of elevated blood pressure have been reported in patients taking MAO inhibitors who were then given buspirone HCl.
Use of sympathomimetics and compounds such as guanethidine, methyldopa, reserpine, dopamine, levodopa, and tryptophan with PARNATE may precipitate hypertension, headache, and related symptoms. Cerebral hemorrhage may also occur.
Do not use meperidine concomitantly with MAO inhibitors or within 2 or 3 weeks following MAOI therapy. Serious reactions have been precipitated with concomitant use, including coma, severe hypertension or hypotension, severe respiratory depression, convulsions, malignant hyperpyrexia, excitation, peripheral vascular collapse, and death.
The use of Parnate in combination with cheese or other foods with a high tyramine content may cause fatal hypertension. Avoid the following foods:
• all matured or aged cheeses (note: all cheeses are considered matured or aged except fresh cottage cheese, cream cheese, ricotta, and processed cheese. All non-cheese dairy products can be consumed providing they are fresh)
• all aged, cured or fermented meat, fish, or poultry (note: meat, fish, or poultry that has not undergone aging, curing or fermenting and that is bought fresh, stored correctly and eaten fresh is not contraindicated)
• all fermented soybean products (e.g., soy sauce, miso, fermented tofu)
• fava or broad bean pods
• banana peel (but not the pulp)
• concentrated yeast extracts (e.g., Marmite or Vegemite spread)
• all tap/draught beers (note: some bottled beers, including non-alcoholic beer, may also pose a risk).
Patients should be advised to minimize or avoid use of all alcoholic beverages while taking Parnate.
The most important reaction associated with PARNATE is the occurrence of hypertensive crises which have sometimes been fatal. These crises are characterized by some or all of the following symptoms: occipital headache which may radiate frontally, palpitation, neck stiffness or soreness, nausea or vomiting, sweating (sometimes with fever and sometimes with cold, clammy skin), and photophobia. Either tachycardia or bradycardia may be present, and associated constricting chest pain and dilated pupils may occur. Intracranial bleeding, sometimes fatal in outcome, has been reported in association with the paradoxical increase in blood pressure.
Safety and effectiveness in the pediatric population have not been established.
