Fentanyl sublingual spray is a drug used for relieving breakthrough cancer pain in people who are already taking an around-the-clock pain medication. This strong narcotic opioid has a high potential for abuse. The medicine comes as a liquid that is sprayed under the tongue every four hours as needed for pain relief. Side effects may include vomiting, dizziness, and constipation.
What Is Fentanyl Sublingual Spray?Fentanyl sublingual spray (Subsys®) is a prescription opioid pain medication approved to manage breakthrough pain (intense flares of pain that "break through" regularly scheduled pain medication) in people with cancer who are already taking opioid pain medication around-the-clock for their persistent cancer pain. It comes in the form of a liquid that is sprayed under the tongue.
Are There Side Effects?Just like any medicine, fentanyl sublingual spray can cause side effects. However, not everyone who uses the drug will experience problems. In fact, most people tolerate it quite well.
