What is the recommended trough level monitoring range for Tacrolimus?

Tacrolimus is an immunosuppressive medication commonly used after organ transplants. The recommended trough level monitoring range for Tacrolimus is 3-15 ng/mL. This range allows healthcare providers to ensure that the drug is within therapeutic levels to prevent organ rejection while minimizing the risk of toxicity. Options B, C, and D provide monitoring ranges that are either too high or too narrow, which can lead to suboptimal treatment outcomes or an increased risk of adverse effects.
