What is Subsys?
Subsys is the brand name for fentanyl sublingual tablets (a fast-acting opioid). It is used for breakthrough cancer pain in people who already take around-the-clock opioid medicine for their condition.
What is Subsys used for?
Subsys is prescribed only for breakthrough pain episodes in patients with cancer who are opioid-tolerant (already taking steady opioid therapy). This “breakthrough” use is different from using opioids to treat ongoing (background) pain.
What are the safety risks with Subsys?
Because Subsys contains fentanyl, it carries the same core risks as other fentanyl products, including:
- Overdose and death if taken incorrectly or by someone who is not prescribed the medicine
- Severe respiratory depression (slowed or stopped breathing)
- Higher risk of harm with misuse, diversion, or accidental exposure, especially in households with children

Is Subsys still available?
Availability can vary by market and over time due to regulatory actions, manufacturer changes, and litigation outcomes. If you tell me your country (US, Canada, EU, etc.) and what you’re trying to find (availability, generic alternatives, dosing, or litigation), I can narrow it down.
Quick check: what did you mean by “Subsys”?
People sometimes search “Subsys” to mean different things (brand fentanyl, legal cases about opioid marketing, or alternative formulations). If you share the context—like “Subsys recall,” “Subsys patent,” or “Subsys vs generics”—I can answer the specific question.
