Fentanyl transdermal patches (Duragesic) are used in chronic pain management. The patches work by slowly releasing fentanyl through the skin into the bloodstream over 48 to 72 hours, allowing for long-lasting pain management. Dosage is based on the size of the patch, since, in general, the transdermal absorption rate is constant at a constant skin temperature. The rate of absorption is dependent on a number of factors.

Body temperature, buy fentanyl online skin type, amount of body fat, and placement of the patch can have major effects. The different delivery systems used by different makers will also affect individual rates of absorption. buy painkiller online.

Under normal circumstances, the patch will reach its full effect within 12 to 24 hours; thus, fentanyl patches are often prescribed with a fast-acting opiate (such as morphine or oxycodone) to handle breakthrough pain.
