What is the therapeutic range of Lithium (Eskalith)?
0.6-1.5
0.1-0.5
0.2-0.5
0.4-1.6
The Correct Answer is A
Choice A rationale: The therapeutic range of lithium is generally considered to be 0.6-1.5 mEq/L. However, some patients may require higher or lower levels depending on their individual response to the medication and their clinical condition. Lithium has a narrow therapeutic range hence the blood level of the drug should be closely monitored to minimize the risk of toxicity and sub-therapeutic effects.
Choice B rationale: 0.1-0.5 is too low hence the drug will provide sub-optimal effects thus providing inadequate mood stabilization.
Choice C rationale: 0.2-0.5 is too low hence the drug will provide sub-optimal effects thus providing inadequate mood stabilization.
Choice D rationale: 0.4-1.6 the lower limit is too low and may result in sub-therapeutic effects while the upper limit is too high and increases the risk of lithium toxicity which can manifest as nausea, vomiting, tremors, seizures, and death in severe cases.
