Seroquel use has been linked to several rare but severe side effects. Seroquel’s side effects include:

Seroquel Side Effects: Tardive Dyskinesia

Tardive Dyskinesia is a serious side effect of Seroquel. Tardive Dyskinesia is a neurological disorder that damages the system that processes neurotransmitter dopamine. Dopamine affects brain processes that control movement, emotional response, and the ability to experience pleasure and pain. Evidence shows that Tardive Dyskinesia is a side effect of neuroleptic drugs. Seroquel, a neuroleptic drug, may cause Tardive Dyskinesia by blocking and reducing the dopamine’s effect on the brain.

Tardive Dyskinesia is characterized by sudden, repetitive, and uncontrolled movement. Tardive Dyskinesia side effects may include:

  • tongue protrusion
  • lip smacking
  • lip puckering and pursing
  • rapid eye blinking

Seroquel Side Effects: Neuroleptic Malignant Syndrome

Neuroleptic Malignant Syndrome (NMS) is a life-threatening neurological disorder. NMS is caused by decreased dopamine levels in the brain. NMS has only been reported in patients taking antipsychotic drugs. Experts believe that NMS is a serious side effect of Seroquel, an antipsychotic drug, because Seroquel reduces the brain’s dopamine level.

Neuroleptic Malignant Syndrome’s side effects may include:

  • Fever
  • Muscular rigidity
  • Altered mental status
  • Autonomic dysfunction

Seroquel Side Effects: Birth Defects / Unwarranted Pregnancies

Scientists are unsure if birth defects are a side effect of Seroquel use because pregnant women were not tested during clinical trials. In animal studies, scientists discovered that Seroquel is toxic to developing fetuses. Therefore, pregnant women are advised to speak with their doctors before using Seroquel. Government regulatory experts advise pregnant women to take Seroquel only if the benefits outweigh the risks.

Seroquel use places women at an increased risk for unwanted pregnancies. Experts realized an increased fertility rate in women taking second generation (or atypical) antipsychotic medications compared to women taking first generation. The FDA and AstraZeneca, Seroquel’s manufacturer, were criticized for not warning women about the increased fertility risk.
