What Are the Dangers of Seroquel?

Seroquel is a drug commonly used to treat bipolar disorder or schizophrenia. A mood regulator and deterrent to depression and other symptoms of such disorders, Seroquel comes with its share of side effects. Fortunately, many can be treated by other medicines, available either over the counter or by prescription from a psychiatrist.

Demographics

• It is important that certain age groups, especially those with certain conditions, avoid Seroquel. The elderly, particularly those with memory problems and symptoms of dementia, should not take Seroquel, because it can cause degenerative effects in health after a certain age, when the immune system is weaker. In addition, patients under the age of 18 are not prescribed Seroquel, because of the potential risk of suicide in those with less experience with depressive symptoms.

  Pregnant women also should avoid Seroquel, because it can have a negative effect on fetal development. In animal testing, embryos encountered toxicity, meaning fetuses may be poisoned. According to the literature accompanying a Seroquel prescription, it should be given to pregnant women only "if the potential benefit justifies the potential risk to the fetus."

Harmful Effects

• Seroquel can cause neuroleptic malignant syndrome (NMS) and tardive dyskinesia. NMS comes in the form of high fevers, rigid or weakened muscles with considerable pain, shaking, confusion and changes in pulse, blood pressure and heart rate. NMS can be fatal, so any of these symptoms would be reason to discontinue the use of Seroquel.

  Tardive dyskinesia is a similarly serious condition that causes uncontrollable movements of the face and tongue, though it may spread beyond that. This condition may worsen if the use of Seroquel continues.

Suicidal Thoughts

• Because bipolar medication regulates the level of serotonin in the brain, it can occasionally decrease those levels rather than level them off. As a result, the symptoms of depression, such as suicidal tendencies, might increase.

Common Side Effects

• Some of the common side effects that occur with many other medications can occur with Seroquel. These include dry mouth, constipation, stomach problems, dizziness or light-headedness when standing or sitting, stuffy nose and sinus issues, trouble speaking and hunger.

  Drowsiness is another possible side effect, so you should avoid driving until you understand the effect Seroquel has you. Drowsiness also can lead to distraction from everyday activities and increase the risks posed by drinking alcohol.

Other Factors

• Several other less common side effects can occur with Seroquel, including weight gain and increases in triglycerides and cholesterol. All three of these in combination can lead to extreme weight gain, which must be countered with increased exercise and a stricter diet. Your general practitioner can offer more advice on these issues.
