Duragesic and other Fentanyl patches release Fentanyl dosages transdermally (through the skin and into the bloodstream). The dosage is regulated by body heat, which is why immersing the patch in hot water, exposing it to sunlight, getting a fever, or engaging in activity that raises core body temperature, can increase the dosage delivery rate and cause problems if the patient/family/friends aren't educated on the precautions and what to do if they start feeling the effects of an increased dose.
