Tricyclic antidepressants and tetracyclic antidepressants

Stopping treatment with cyclic antidepressants

Cyclic antidepressants aren't considered addictive. However, stopping antidepressant treatment abruptly or missing several doses can cause withdrawal-like symptoms. Symptoms may vary depending on how the drug works. This is sometimes called discontinuation syndrome. Work with your doctor to gradually and safely decrease your dose.

Withdrawal-like symptoms can include:

  • Agitation, irritability or anxiety
  • Nausea
  • Sweating
  • Flu-like symptoms, such as chills and muscle aches
  • Insomnia
  • Lethargy
  • Headache
