1Optmizing the SSRI dose: Full medication effects will not be observed until 4-6 weeks after initiation; however, some response should be observed at 2-3 weeks of a therapeutic dose. If no response at 2-3 weeks, the dose should be increased. Optimal dose is when significant improvement occurs in presenting symptoms, PHQ-9 score is <5 and side effects of medication are either absent or tolerable
2Side effect evaluation: If mild, wait 7 days to determine if transient. If they persist but are tolerable, continue on the dose. If side effects are moderate, reduce the dose or change the dosing schedule or drug. If side effects are severe, discontinue or change the medication as soon as possible.
3 Treatment Emergent Activation Syndrome (TEAS) (common and tends to occur in early treatment phase; presents as agitation, dysphoria, or akathisia, with no striking mood changes) may occur with any SSRI, consult BHI team if concerns arise; often responds to dose reduction or slowed titration.
Other potential common side effects may include: dry mouth, sweating, irritability, disinhibition, agitation, jitteriness, appetite changes, or rash
More serious, less common side effects include: serotonin syndrome, akathisia, hypomania, or discontinuation syndrome
