Final answer:
Physicians must carefully monitor the dose of lithium they give to bipolar patients because it has a narrow therapeutic range and can have side effects if not properly managed. Regular blood tests are often done to maintain lithium levels within the therapeutic range and prevent toxicity.
Step-by-step explanation:
Physicians must carefully monitor the dose of lithium they give to bipolar patients because it is a powerful medication that can have side effects if not properly managed. Lithium is used to stabilize mood in bipolar disorder, but it has a narrow therapeutic range, meaning there is a fine line between an effective dose and a toxic dose.
Monitoring the dose of lithium is important because too little can result in inadequate control of bipolar symptoms, while too much can lead to toxicity. Symptoms of lithium toxicity include confusion, tremors, and seizures. Regular blood tests are often done to maintain levels within the therapeutic range and to prevent these side effects.
In addition, other factors such as diet, hydration, and the use of other medications can influence the levels of lithium in the body. Therefore, close monitoring and individualized treatment are necessary to ensure the safety and effectiveness of lithium therapy in bipolar patients.
