SSRIs (selective serotonin reuptake inhibitors) are antidepressants that affect serotonin levels in the brain. It’s not fully understood how they work but it is thought they provide higher levels of serotonin at the brain receptor site. SSRI discontinuation syndrome can occur during or following interruption or the lowering of dosage or the discontinuation of an SSRI or SNRI (serotonin-norepinephrine reuptake inhibitor) antidepressant.

Side effects can occur between 24 hours to one week after reduction or stoppage of dosage and they can be overwhelming. Side effects may include dizziness, electric shock-like sensations or “zaps,” sweating, nausea, insomnia, tremor, confusion, and vertigo.

Read her personal story and tips on gradually weaning off SSRIs on the site’s blog.
