The FDA advises that consumers who have purchased this drug through the Internet and taken it for the treatment of bi-polar disease (manic-depressive illness) could experience adverse events associated with lowered blood lithium levels. These events could include a worsening of manic-depressive illness, a serious psychiatric condition. A worsening of this condition could result in symptoms associated with mania (such as motor hyperactivity, delusions of grandeur, poor judgment and aggressiveness) and depression or suicidal thoughts which may require hospitalization.
Additionally, consumers who may have taken the Carbolith product for several weeks or more may experience toxic effects when they switch to a lithium carbonate product that delivers adequate amounts of the drug. Mild toxicity could result in tremors of the hands, thirst and more frequent urination, drowsiness, ringing in the ears and blurred vision. More severe toxicity could result in confusion, muscle twitching, vomiting, diarrhea, seizures, coma and death.
