How does linezolid cause serotonin syndrome?

Drugs in the MAO-inhibitor class—for example, linezolid—cause increases in synaptic concentrations of biogenic amines (eg, dopamine, norepinephrine, and serotonin). When these agents are combined with proserotonergic agents, synaptic concentrations of serotonin rise to toxic levels and precipitate the syndrome.

How does metoclopramide cause serotonin syndrome?

Metoclopramide contributes to serotonin syndrome by impairing its reuptake from the synaptic cleft into the presynaptic neuron [9]. Metoclopramide is metabolized through the liver and excreted in urine.

What medications can 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)

When should I restart SSRI after linezolid?

Treatment with the serotonergic psychiatric medication may be resumed 24 hours after the last dose of linezolid. Serotonergic psychiatric medications should not be started in a patient receiving linezolid. Wait until 24 hours after the last dose of linezolid before starting the antidepressant.

How do you treat serotonin syndrome?

Depending on your symptoms, you may receive the following treatments:

  1. Muscle relaxants.
  2. Serotonin-production blocking agents.
  3. Oxygen and intravenous (IV) fluids.
  4. Drugs that control heart rate and blood pressure.
  5. A breathing tube and machine and medication to paralyze your muscles.

Is Reglan a serotonin antagonist?

Mechanism of Action. Metoclopramide is principally a dopamine D2 antagonist but also acts as an agonist on serotonin 5-HT4 receptors and causes weak inhibition of 5-HT3 receptors.

Does serotonin syndrome happen quickly?

Most cases of serotonin syndrome start within 24 hours after starting or increasing a serotonergic medication and the majority of those start within six hours.

How do you get rid of serotonin syndrome?

Milder forms of serotonin syndrome usually go away within 24 to 72 hours of stopping medications that increase serotonin. You may need to take medications to block the effects of serotonin already in your system.

What is the most serious side effect of Reglan?

REGLAN can cause serious side effects, including: Abnormal muscle movements called tardive dyskinesia (TD). These movements happen mostly in the face muscles. You can not control these movements.
