1
Waiting at least 5 half lives after discontinuing antidepressant before starting MAOI
2
It has a very long half life and will need to wait at least 5 weeks before starting an MAOI
3
Wait at least 14 days to start antidepressant because that is the time it takes the liver to produce new MAO enzymes
4
Not okay: "anything fermented" - Dried, aged, smoked, fermented, spoiled, or improperly stored meat, poultry, or fish; broad bean pods ; aged cheese; tap and unpasteurized beer; marmite; sauerkraut and kimchee; soy and tofu; banana peel; tyramine-containing products Okay: processed cheese/yogurts; canned or bottled beer/alcohol; products containing yeast
5
Serotonin Syndrome = Excess serotonergic activity, often due to combining serotonergic drugs (e.g., SSRI + MAOI, SNRI + triptan, linezolid, dextromethorphan, MDMA) Hypertensive Crisis = Ingestion of tyramine-rich food or sympathomimetic drugs while on MAOI, especially irreversible MAO-A inhibitors
6
Serotonin Syndrome: Rapid (within hours of drug ingestion or dose change) Hypertensive Crisis: Rapid (within minutes to a few hours after tyramine exposure)
7
Serotonin Syndrome: Clonus (esp. inducible or spontaneous), hyperreflexia, tremor, myoclonus, agitation Hypertensive Crisis: May have tremor, agitation, but clonus and hyperreflexia are absent
8
Serotonin Syndrome: Diaphoresis, hyperthermia, tachycardia, hypertension, dilated pupils Hypertensive Crisis: Severe hypertension, flushing, headache, sweating, nosebleed, possible bradycardia reflex
9
Serotonin Syndrome: Altered (agitation, confusion, delirium) Hypertensive Crisis: Usually preserved until BP reaches critical levels
10
Serotonin Syndrome: Often elevated (can exceed 104°F) Hypertensive Crisis: May have low-grade fever or be afebrile
11
Serotonin Syndrome: -Stop all serotonergic agents immediately -Supportive care: IV fluids, cooling, benzodiazepines for agitation -For moderate to severe cases: Cyproheptadine (5HT2A antagonist) -Avoid antipyretics (ineffective in central hyperthermia) -ICU care if temp >106°F or vital instability Hypertensive Crisis: -Immediate discontinuation of MAOI -Administer phentolamine (alpha-blocker) or nifedipine (CCB) for BP control -ICU monitoring if end-organ damage suspected (e.g., stroke symptoms) -Strict diet education to prevent recurrence

53
Works on numerous serotonin pathways in unique ways (5TH1A, 5HT1B, 5HT1D, 5HT3, and 5HT7) - seems to be weight neutral - much lower incidence of sexual side effects - may have a "pro-cognitive" effect? - notorious for causing nausea - Use cautiously with Wellbutrin (max dose when combined with Wellbutrin is 10 mg)

The abundance of serotonin in the somatodentriti stimulates 5-HT1A autoreceptors. Then 5-HT1A receptors are downregulated and since they are the gatekeepers this allows greater release of serotonin at the axon terminal.
