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.
Like other fentanyl medications, fentanyl sublingual spray is a Schedule II
controlled substance. Schedule II controlled substances are considered to have the highest abuse potential of all prescription medications. As a controlled substance, there are strict laws and regulations controlling the use of this medication.
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.
If reactions do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider. Serious reactions are less common.
