general mechanism of action
all antidepressants work by increasing neurotransmitters
monoamine deficiency hypothesis
major depression is caused by a relative lack of neurotransmitters
why does it take a long time for full effects to be seen
this is because antidepressants resensitize the pathways of neurotransmitters and this takes time
what do all antidepressants cause
weight gain
sucicide risk (increase in younger)
sexual dysfunction
TCAs adverse effects
orthostatic hypotension, sedation, anti SLUD, sweating, cardiotoxcity, seizures, suicide risk
most effects are due to blocking other receptors

what are risk factors
too much serotonin stimulation
