drug_recall risperdalRisperdal is an anti-psychotic medication used to treat a variety of psychotic disorders, including schizophrenia. It has also recently been FDA approved for the treatment of manic and mixed episodes associated with bipolar disorder, either used alone or in conjunction with mood stabilizers, such as lithium and valproate.
People with bipolar disorder suffer from chemical imbalances of dopamine and seratonin in the brain. These imbalances are thought to encourage the exaggerated feelings associated with mania, including: unrealistic beliefs in one''s ability; exaggerated confidence; excessive energy, activity or restlessness; decreased need for sleep; racing thoughts or rapid talking; and uncharacteristically poor judgment, which may involve reckless driving, spending sprees and foolish business ventures.
The chemical imbalance of bipolar disorder also causes depressive episodes characterized by feelings of sadness, anxiety, emptiness, guilt, hopelessness and worthlessness. Other symptoms of depressive episodes include: sleeping or eating too much or too little ; loss of interest or pleasure in activities, including sex ; difficulty concentrating, remembering, or making decisions ; fatigue or loss of energy; and physical symptoms that don''t respond to treatment, such as chronic pain or digestive disorders.
Risperdal treats these imbalances by interfering with the communication between the nerves of the brain. The drug enters the brain and blocks the receptors of dopamine and seratonin to intercept them from making changes in the brain cells. By disallowing the chemicals from becoming imbalanced, Risperdal can prevent the manic, depressed and mixed episodes of bipolar disorder.
Doctors usually produce Risperdal in two small doses per day to start, increasing the dosage gradually until the patient receives optimal results. It is important to find the proper dosage, as many anti-psychotic drugs can produce serious side effects. Some reactions to Risperdal may include: sleepiness, muscle stiffness, restlessness, tremor, indigestion, nausea, abnormal vision, muscle aches, dizziness, runny nose, diarrhea, increased saliva, stomach pain and urinary incontinence. Risperdal may also cause a decrease in blood pressure and an increase in blood sugar, and may lead to the development of tardive dyskinesia, a condition that causes jerky, involuntary movements of the head, neck, arms, body or eyes.
