Side Effects of Fentanyl Sublingual Tablets

Common Side Effects

Fentanyl sublingual tablets have been studied thoroughly in clinical trials. In these studies, the side effects that occurred in a group of people taking the drug were carefully recorded. In all the studies, long-acting opioid narcotics were used in addition to fentanyl sublingual tablets. Therefore, it can be difficult to know whether any adverse reactions were due to the tablets or the other opioid medication.
