Lithium may occasionally affect blood glucose levels. Both hyperglycemia (high blood sugar) and, less frequently, hypoglycemia (low blood sugar) have been reported. Your blood glucose should be closely monitored during treatment with lithium so that your diabetic regimen may be adjusted, if needed. Let your doctor know if you experience hyperglycemia or hypoglycemia, or if you notice a loss of blood glucose control. Symptoms of hyperglycemia may include increased thirst, increased hunger, and increased urination. Symptoms of hypoglycemia include headache, dizziness, drowsiness, nervousness, confusion, tremor, nausea, hunger, weakness, perspiration, palpitation, and rapid heartbeat. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Alcohol can increase the nervous system side effects of lithium such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with lithium. Do not use more than the recommended dose of lithium, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
