Why are MAOIs contraindicated with SSRIs?

It is generally considered dangerous to combine monoamine oxidase inhibitors and SSRIs because MAOIs inhibit serotonin metabolism and can result in circulating serotonin levels that are high enough to produce cardiotoxic and neurotoxic serotonin syndrome.

Which drugs cause serotonin syndrome?

The drugs and supplements that could potentially cause serotonin syndrome include: Selective serotonin reuptake inhibitors (SSRIs), antidepressants such as citalopram (Celexa), fluoxetine (Prozac), fluvoxamine (Luvox), escitalopram (Lexapro), paroxetine (Paxil, Pexeva, Brisdelle) and sertraline (Zoloft)

Can you take MAOI with SSRI?

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.

How do MAOIs increase serotonin?

MAOIs elevate levels of the neurotransmitters norepinephrine, serotonin, and dopamine in the brain by inhibiting an enzyme called monoamine oxidase. Monoamine oxidase breaks down norepinephrine, serotonin, and dopamine.

What drugs Cannot be taken with MAOIs?

What drugs interact with MAOIs? MAO inhibitors should be avoided with other antidepressants such as paroxetine fluoxetine, amitriptyline, nortriptyline, bupropion; pain medications like methadone, tramadol, and meperidine; dextromethorphan, St. Johns Wort, cyclobenzaprine, and mirtazapine.

How much time should elapse between giving MAOIs and SSRIs?

When clinicians feel the need to switch from one class of agent to the other, it is suggested that at least five half-lives elapse between the time the SSRI is stopped and the MAOI is started.

What is the washout period for MAOI and SSRI?

From SSRIs to TCAs and from TCAs to SSRIs because certain SSRIs (mostly fluvoxamine, fluoxetine and paroxetine) will inhibit the metabolism of TCAs.

What is the difference between MAO inhibitors and SSRIs?
