Escitalopram and SAMe, a caution.
SAMe has serotonergic properties that may potentiate escitalopram's effects. While some psychiatrists use SAMe augmentation in treatment-resistant depression, the combination requires careful monitoring due to the risk of excessive serotonergic stimulation.

Caution
What is happening. SAMe has serotonergic properties that may potentiate escitalopram's effects. While some psychiatrists use SAMe augmentation in treatment-resistant depression, the combination requires careful monitoring due to the risk of excessive serotonergic stimulation.
Mechanism. SAMe enhances serotonin synthesis and turnover through methylation reactions and increases postsynaptic serotonin receptor sensitivity. Combined with escitalopram's selective SERT inhibition, synaptic serotonin levels can rise excessively.
Recommendation. Only combine SAMe with escitalopram under direct psychiatric supervision. Do not add SAMe on your own. Start at low doses if prescribed together, and monitor for signs of serotonin excess.
