Which medication is NOT typically considered a high alert drug?

Metformin is not typically considered a high alert drug because it is generally used for the management of type 2 diabetes and has a wide therapeutic index. This means that the dosage can be adjusted safely for most patients without a high risk of significant adverse effects or severe complications when taken as directed. High alert medications are those that have a higher potential to cause harm if used incorrectly, even when used for the right reasons.

In contrast, insulin, potassium, and digoxin are frequently classified as high alert drugs. Insulin requires careful management to avoid hypoglycemia and has a narrow therapeutic range. Potassium is critical for many bodily functions, and improper dosing can lead to serious cardiac complications. Digoxin, used to treat heart conditions, also has a narrow therapeutic index and can lead to toxicity, particularly in patients with kidney impairment. The careful monitoring and administration requirements of these medications highlight why they are classified as high alert.
