What effects does sertraline have?
Sertraline's official side-effect profile understates chemically significant neurological and endocrine disruption. Critics from the critical psychiatry tradition argue the drug's mechanism — chronic serotonin transporter blockade — induces adaptive changes the brain struggles to reverse. The withdrawal syndrome, often mislabelled relapse, and persistent sexual dysfunction (PSSD) represent harms rarely foregrounded in prescriber conversations.
Evidence
- Peter Breggin, psychiatrist and author of Toxic Psychiatry and Psychiatric Drug Withdrawal, argues that SSRI-induced emotional blunting, apathy and anhedonia are direct pharmacological effects of serotonergic saturation — not side effects in the incidental sense, but the mechanism itself flattening affective range.
- Mark Horowitz and David Taylor published research on hyperbolic tapering, demonstrating that standard discontinuation schedules cause neuroadaptive rebound because serotonin transporter occupancy does not scale linearly with dose.
- Breggin additionally flags sertraline's association with akathisia — an inner motor restlessness the Mayo Clinic lists as a rare effect — as an underreported driver of suicidal and homicidal ideation, a link he has testified to in US court cases involving SSRI-linked violence.
- He contends clinical trials systematically obscure this by measuring symptom checklists rather than subjective experience of selfhood.
- Their work, adopted cautiously by NICE in the UK, implies sertraline creates physiological dependence the mainstream framing long denied.
