People taking MAOIs generally need to change their diets to limit or avoid foods and beverages containing tyramine Tyramine, also known under several other names, is a naturally occurring trace amine derived from the amino acid tyrosine. Tyramine acts as a catecholamine releasing agent. Notably, it is unable to cross the blood-brain barrier, resulting in only non-psychoactive peripheral sympathomime…Tyramine
Are monoamine oxidase inhibitors (MAOIs) safe?
Monoamine oxidase inhibitors (MAOIs) Use of MAOIs typically requires diet restrictions because they can cause dangerously high blood pressure when taken with certain foods or medications. In spite of side effects, these medications are still a good option for some people. In certain cases, they relieve depression when other treatments have failed.
Do not take with Mao drugs?
The words “do not take with MAO drugs” or “do not take for at least two weeks after discontinuing an MAOI” are common under drug interaction. The reason many drugs interact with MAOIs is that the chemical norepinephrine, a powerful blood vessel constrictor that many over the counter medications increase, is also increased by MAOIs.

What happens when you stop taking MAOIs?
Stopping treatment with MAOIs. Stopping treatment with MAOIs has been associated with flu-like symptoms, including anxiety, agitation, insomnia, sweating, chills, nausea, headache and feeling generally unwell (malaise). If you stop an MAOI suddenly, you're more likely to experience a withdrawal-type reaction.
What can you not take with MAO inhibitors?
You'll need to avoid foods containing high levels of tyramine ― an amino acid that regulates blood pressure ― such as aged cheeses, sauerkraut, cured meats, draft beer and fermented soy products (for example, soy sauce, miso and tofu). The interaction of tyramine with MAOIs can cause dangerously high blood pressure.
Which food should be avoided by a client who is prescribed monoamine oxidase inhibitors MAOIs?
Smoked or processed meats, such as hot dogs, bologna, bacon, corned beef or smoked fish. Pickled or fermented foods, such as sauerkraut, kimchi, caviar, tofu or pickles. Sauces, such as soy sauce, shrimp sauce, fish sauce, miso and teriyaki sauce. Soybeans and soybean products.
What drug class should never be given at the same time as an MAOI?
[9] For example, patients should not be mixing MAOIs with other antidepressants like selective serotonin reuptake inhibitors (SSRIs). [12] These two drugs combined can cause serotonin syndrome, which is potentially fatal.
What is the life threatening side effect for a person taking an MAOI?
Dangerously high levels of serotonin in the brain can cause a potentially life-threatening condition called serotonin syndrome. This rare condition is usually the result of an interaction of two or more drugs that affect brain serotonin levels.
What to avoid while on antidepressants?
Avoid driving or operating machinery. Avoid caffeine, tobacco and alcohol. Drink plenty of fluids. Take your antidepressant at bedtime if your doctor approves.
What foods should be avoided with SSRI?
Tyramine-Rich Food Products:Interaction between sertraline and tyramine-rich foods like cheese, milk, beef, chicken liver, meat extract, avocados, bananas, canned figs, soy beans and excess chocolate can result in a sudden and dangerous increase in blood pressure.
What would be useful to treat someone who has monoamine oxidase inhibitor toxicity?
There are no antidotes for MAOI toxicity. Hemodialysis is ineffective in removing the drug from the body. Rapid correction of hyperthermia is vital. Cooling by evaporative heat loss (wetting skin and creating air flow with fans) is an effective treatment.
Can you mix SSRI with MAOI?
The use of SSRIs and SNRIs should be avoided with an MAOI because of the risk of serious adverse effects and even death. The combination has a high risk of serotonin syndrome, and deaths have been reported when taken at therapeutic doses.
What would you tell a resident who is taking an MAO inhibitor about food interactions?
Certain foods and drinks can cause dangerous reactions if they're taken with an MAOI. Your physician will probably tell you to avoid foods that contain high levels of tyramine, dopamine, and tryptophan.
Why do MAO inhibitors cause hypotension?
National Institutes of Health, Bethesda, Md. A number of investigators have speculated that MA0 inhibitors elicit orthostatic hypotension by interfering with transmission in sympathetic ganglia.
How do monoamine oxidase MAO inhibitors work quizlet?
How does MAOI's work? Inhibit MAO enzyme, which is present in the brain, Platelets, liver, spleen and kidneys, which in turn metabolize the amines, norepinephrine and serotonin.
What can happen if the amino acid is not avoided while taking an MAOI?
If you take an MAOI and you eat high-tyramine foods, tyramine can quickly reach dangerous levels. This can cause a serious spike in blood pressure and require emergency treatment. Avoid consuming foods that are high in tyramine if you take an MAOI.

How does MAO B work?
It works by selectively blocking monoamine oxidase B (MAO-B). This reduces the breakdown of dopamine and phenethylamine and means there are no dietary restrictions. It’s available in patch form. Learn about other medications used to treat depression.
Why do people take MAOIs?
Because MAOIs inhibit monoamine oxidase from doing its job, they adversely affect blood pressure in addition to keeping neurotransmitters at optimal levels. People taking MAOIs have to pay special attention to their blood pressure, including avoiding certain foods.
What is the effect of monoamine oxidase on mood?
By inhibiting monoamine oxidase, MAOIs allow more of these neurotransmitters to remain in the brain, thus elevating mood through improved brain cell communication.
What are MAOIs in the brain?
MAOIs work with the chemicals in your brain called neurotransmitters that allow brain cells to communicate with each other. Depression is thought to be caused by low levels of the neurotransmitters dopamine, serotonin, and norepinephrine, which collectively are called monoamines. A chemical found naturally in the body, monoamine oxidase, ...
What is monoamine oxidase?
Understanding monoamine oxidase. Monoamine oxidase is a type of enzyme that helps neurons fire throughout your body. It’s formed in your liver and cleans up neurotransmitters in your brain once they’ve done their jobs. Besides neurotransmitters, monoamine oxidase cleans out tyramine, a chemical that helps regulate blood pressure.
How long does it take for isocarboxazid to work?
isocarboxazid (Marplan): can take three to six weeks to fully take effect. phenelzine (Nardil): can take up to four weeks to fully work. tranylcypromine (Parnate): can take up to 3 weeks to achieve its desired effects.
When were MAOIs first used?
They were introduced in the 1950s as the first drugs for depression. Today, they’re less popular than other depression medications, but some people benefit from their use. Read on to learn more about MAOIs, including how they work, who they might help, and what foods to avoid while taking them.
What is the function of MAO inhibitors?
Monoamine oxidase inhibitors (also called MAO inhibitors or MAOIs) block the actions of monoamine oxidase enzymes. Monoamine oxidase enzymes are responsible for breaking down neurotransmitters such as dopamine, norepinephrine, and serotonin in the brain.
How long does it take for blood pressure to increase after taking MAOI?
Rarely, rapid but transient increases in blood pressure within 30 minutes to two hours of MAOI ingestion. MAOIs should not be given to people with heart disease or high blood pressure, or to people with pheochromocytoma. They should be discontinued 10 days prior to elective surgery.
Why are MAOIs used?
MAOIs are typically only used when other antidepressants have proven ineffective, because they have a higher risk ...
How long do MAOIs last?
When taken at the recommended dosage, MAOIs are considered safe. However, they are potentially fatal in overdose and have also been associated with a few serious, potentially fatal, side effects such as: 1 Very severe drug interactions. Since the effects of MAOIs persist for several weeks after the last dose is taken, at least a 14-day washout period is required before starting any other type of antidepressant or medicine that also increases levels of serotonin or other chemical neurotransmitters 2 Very severe food interactions. Extremely high blood pressure, which could lead to a fatal stroke, may result if foods high in tyramine such as aged cheeses, fermented meats, Fava or broad beans, beer, marmite, or soy sauce, are consumed while taking MAOIs 3 An increase in suicidal thoughts and behaviors, particularly in children and young adults under the age of 25 years. This is most likely to occur when starting therapy 4 Serotonin syndrome, usually when MAOIs are taken in conjunction with other medicines or supplements that also increase serotonin, or when taken at high dosages. Symptoms include confusion, restlessness, muscle jerking, and excessive sweating 5 Rarely, rapid but transient increases in blood pressure within 30 minutes to two hours of MAOI ingestion.
What are some examples of MAOIs?
Some resources may not list these drugs as MAOIs even though they inhibit monoamine oxidase enzymes. Examples include: Linezolid ( Zyvox ): an antibiotic used to treat certain bacterial infections that are resistant to other antibiotics.
What is the best medication for Parkinson's?
Procarbazine ( Matulane ): Used in addition to other medications to treat Hodgkin’s disease. Rasagiline ( Azilect ): Used to treat symptoms of Parkinson’s disease. Selegiline ( Eldepryl, Zelapar ): May be used for the treatment of Parkinson’s disease in addition to other medications.
Can you have a stroke with tyramine?
Extremely high blood pressure, which could lead to a fatal stroke, may result if foods high in tyramine such as aged cheeses, fermented meats, Fava or broad beans, beer, marmite, or soy sauce, are consumed while taking MAOIs.
How does MAO inhibitor work?
MAO inhibitors work by interfering with the enzyme that is responsible for metabolizing the three neurotransmitter chemicals in the brain: serotonin, norepinephrine and dopamine. MAOI’s increase the concentration of these chemicals and in turn, cause changes within specific areas of the central nervous system. The changes created by the drugs allow for the chemicals to be present in the brain in higher levels (SSRI antidepressants only work on serotonin), and thus, alleviate several forms of atypical, or rarer, more severe forms of depression.
What are the other MAOIs?
The other three MAOIs are: Isocarboxazid (brand name Marplan), phenelzine (brand name Nardil) and Tranylcypromine (brand name Parnate). These drugs are equally prescribed and one is not known as having more efficacy than another. It is important to remember that these drugs are not widely prescribed as their side effect potential is so dangerous, thus not nearly as many clinical tests are conducted. Monitoring a patient’s diet as well as other medications over the counter or prescribed from another doctor are extremely difficult to monitor, and physicians typically do not want the liability of prescribing a drug which can have potentially fatal results.
Is selegeline a MAOI?
If your physician feels that MAOIs are an appropriate treatment, there are only four FDA approved medications available. One of these medications, selegeline (brand name Emsam) is not used for depression but instead for the treatment of Parkinson’s disease. The drug works as an antioxidant and an immunostimulant which protects nerve tissue from degeneration and has positive effects on cognition. The drug is usually prescribed in addition to the most commonly used Parkinson’s medication, L-Dopa and has proven to be effective.
Can MAOI be taken with other drugs?
MAOI’s are very effective in the treatment of depression. These drugs, however, pose serious and even fatal side effects if taken with other drugs or even with certain foods. Everyone is familiar with information posted on many over the counter drugs that most have in their home. The words “do not take with MAO drugs” or “do not take for at least two weeks after discontinuing an MAOI” are common under drug interaction. The reason many drugs interact with MAOIs is that the chemical norepinephrine, a powerful blood vessel constrictor that many over the counter medications increase, is also increased by MAOIs. With both medications increasing norepinephrine levels, the combination could pose potentially fatally high levels within the body.
Can MAOIs cause hypertension?
Unfortunately, severe side effects from taking other medications with MAOIs are not the only potential danger. There are also certain foods that must also be avoided. Monoamine Oxidase is also found in the intestinal tract and is crucial in the breakdown of a substance named “tyramine.” MAOIs, while inhibiting the neurotransmitters, also alter the breaking down of tyramine and therefore, cause higher levels of the substance within the body. Ergo, foods that contain tyramine can result in such high levels that the individual may experience hypertension that can be potentially fatal.
What is the most significant risk associated with the use of MAOIs?
The most significant risk associated with the use of MAOIs is the potential for drug interactions with over-the-counter, prescription, or illegally obtained medications, and some dietary supplements (e.g., St. John's wort, tryptophan ). It is vital that a doctor supervise such combinations to avoid adverse reactions. For this reason, many users carry an MAOI-card, which lets emergency medical personnel know what drugs to avoid (e.g. adrenaline (epinephrine) dosage should be reduced by 75%, and duration is extended.)
What substances can react with MAOIs?
Such substances that can react with MAOIs include: Phenethylamines: 2C-B, mescaline, phenethylamine (PEA), etc. Amphetamines: amphetamine, MDMA, dextroamphetamine, methamphetamine, DOM, etc. Tryptamines: DMT (MAOIs prevent oxidization of DMT in the digestive tract, which renders it biologically inert.
What is a reversible inhibitor of monoamine oxidase A?
Reversible inhibitors of monoamine oxidase A ( RIMAs) are a subclass of MAOIs that selectively and reversibly inhibit the MAO-A enzyme. RIMAs are used clinically in the treatment of depression and dysthymia.
How often do MAOIs turn over?
The enzymes turn over approximately every two weeks.
What is the function of MAOIs?
MAOIs act by inhibiting the activity of monoamine oxidase, thus preventing the breakdown of monoamine neurotransmitters and thereby increasing their availability. There are two isoforms of monoamine oxidase, MAO-A and MAO-B. MAO-A preferentially deaminates serotonin, melatonin, epinephrine, and norepinephrine.
What happens if you eat too much tyramine?
If large amounts of tyramine are consumed, they may suffer a hypertensive crisis, which can be fatal. Examples of foods and beverages with potentially high levels of tyramine include animal liver and fermented substances, such as alcoholic beverages and aged cheeses. Excessive concentrations of tyramine in blood plasma can lead to hypertensive crisis by increasing the release of norepinephrine (NE), which causes blood vessels to constrict by activating alpha-1 adrenergic receptors. Ordinarily, MAO-A would destroy the excess NE; when MAO-A is inhibited, however, NE levels get too high, leading to dangerous increases in blood pressure.
When did MAOIs start to wane?
The older MAOIs' heyday was mostly between the years 1957 and 1970. The initial popularity of the 'classic' non-selective irreversible MAO inhibitors began to wane due to their serious interactions with sympathomimetic drugs and tyramine -containing foods that could lead to dangerous hypertensive emergencies.
