Disease in psychiatry where SSRI are contraindicated

 

Selective Serotonin Reuptake Inhibitors (SSRIs) are commonly prescribed in psychiatry, especially for depression and anxiety disorders. However, there are several psychiatric and medical conditions where SSRIs are contraindicated or should be used with extreme caution due to potential harm.

Here are psychiatric conditions where SSRIs are contraindicated or risky:

---

1. Bipolar Disorder (Especially Bipolar I) – During Depressive Episodes

• Why contraindicated: SSRIs can induce manic or hypomanic switches and rapid cycling.

• Precaution: Should only be used with a mood stabilizer (e.g., lithium, valproate).

---

2. Schizoaffective Disorder or Schizophrenia (if not properly managed)

• Why contraindicated: SSRIs may worsen psychosis in some cases by increasing serotonin and dopamine tone.

• Precaution: Use only under antipsychotic cover and clear depressive component.

---

3. Serotonin Syndrome Risk (esp. in Polypharmacy)

• Why contraindicated: SSRIs combined with other serotonergic agents (e.g., MAOIs, triptans, tramadol, linezolid) can lead to serotonin syndrome — a potentially life-threatening condition.

• Result: Hyperthermia, agitation, autonomic instability, neuromuscular abnormalities.

---

4. History of SSRI-Induced Activation or Akathisia

• Why contraindicated: In susceptible individuals, SSRIs can cause severe restlessness, agitation, or suicidality.

• Precaution: Use alternative classes or start at ultra-low doses with close monitoring.

---

5. Eating Disorders (e.g., Anorexia Nervosa) – Caution

• Why caution: In severely malnourished individuals, SSRIs like fluoxetine may be ineffective due to low serotonin precursors and may increase risk of QT prolongation.

• Note: May be helpful in bulimia nervosa, but always assess electrolyte status.

---

6. Obsessive-Compulsive Disorder (OCD) with Comorbid Tics

• Why caution: In some individuals, SSRIs may exacerbate tics or motor restlessness.

• Alternative: Consider adding or switching to antipsychotics if tics worsen.

---

7. History of Severe Sexual Dysfunction or SSRI-Induced Apathy

• Why caution: SSRIs commonly cause sexual side effects and emotional blunting, which can worsen quality of life or adherence.

---

8. Impulsive or Aggressive Behavior (e.g., in Borderline Personality Disorder)

• Why caution: Some individuals may experience paradoxical increases in impulsivity or disinhibition early in SSRI treatment.
