Med hver ny IONSYS- anbringelse kan patienten anvende IONSYS hyppigere end resten af det foregående døgn pga. lavere absorption af fentanyl fra systemet i de første få timer (jf. afsnit 5. 2).
With each new IONSYS application the patient may use IONSYS more frequently than during the remainder of the 24 hour dosing period, due to a lower absorption of fentanyl from the system for the first few hours (see section 5.2).
