What lab tests may be needed before starting treatment with terbinafine?

Before starting treatment with terbinafine, liver function tests are necessary to assess the patient's liver health. Terbinafine, an antifungal medication, can affect liver function, and there is a risk of hepatotoxicity. By obtaining baseline liver function tests, healthcare providers can monitor for any changes during treatment and intervene if there are signs of liver damage, such as elevated liver enzymes. This proactive approach helps ensure patient safety and allows for appropriate management should any adverse effects occur.

Other potential tests, such as kidney function tests, blood glucose levels, or an electrolyte panel, are less relevant in this context regarding the initiation of terbinafine therapy. While monitoring kidney function can be important in various contexts, it is not specifically indicated for the safe initiation of this medication. Similarly, while blood glucose and electrolyte levels are important in broader healthcare management, they do not directly relate to the risks associated with terbinafine treatment. The focus on liver function reflects the specific concerns linked to this medication.
