Fentanyl is a very strong pain medication that belongs to the opioids and is therefore a pain reliever with a morphine-like effect.
Just like morphine, it blocks certain pain receptors in the spinal cord and brain (it is therefore centrally effective). This blockade of the receptors inhibits the perception of pain and the pain is no longer perceived as unpleasant. Compared to morphine, fentanyl is much more effective.
With all drugs of the opioid group, the body gets used to the pain blocker over time and the effect decreases, so that a constant increase in the active ingredient is necessary. However, correct use of fentanyl for pain management rarely leads to dependence.
Possible side effects that have been observed in individual cases when taking fentanyl, but are by no means necessarily occurring, are:
Dry mouth

If fentanyl is taken together with depressant drugs such as centrally acting drugs, sleeping pills or sedatives, possible side effects of fentanyl are increased.Alcohol can also increase its effects while taking fentanyl and lead to increased side effects.
