What are the different Fentanyl strengths?

Fentanyl is available in various strengths, commonly measured in micrograms per hour (mcg/hr) for transdermal patches and in micrograms per milliliter (mcg/mL) for injectable forms. Transdermal patches typically come in strengths such as 12, 25, 50, 75, and 100 mcg/hr, while injectable fentanyl can be found in concentrations like 50 mcg/mL and higher. The potency of fentanyl is significantly greater than that of morphine, making precise dosing crucial to avoid overdose. Always consult a healthcare professional for appropriate use and dosing.
