Keep SUBSYS in a safe place away from children.
Get emergency medical help right away if:
- a child uses SUBSYS. SUBSYS can cause an overdose and death in any child who uses it.
- an adult who has not been prescribed SUBSYS uses it
- an adult who is not already taking opioids around-the-clock, uses SUBSYS
These are medical emergencies that can cause death.
Read this Medication Guide completely before you start using SUBSYS, and each time you get a new prescription. There may be new information. This Medication Guide does not take the place of talking to your healthcare provider about your medical condition or your treatment. Be sure to share this important information with members of your household and other caregivers.
What is the most important information I should know about SUBSYS?
SUBSYS can cause life-threatening breathing problems which can lead to death.
1. Do not take SUBSYS if you are not opioid tolerant.
2. If you stop taking your around-the-clock opioid pain medicine for your cancer pain, you must stop using SUBSYS. You may no longer be opioid tolerant. Talk to your healthcare provider about how to treat your pain.
3. Use SUBSYS exactly as prescribed by your healthcare provider.
- You must not use more than 2 doses of SUBSYS for each episode of breakthrough cancer pain.

Your healthcare provider will prescribe a starting dose of SUBSYS that may be different than other fentanyl containing medicines you may have been taking.
5. Do not use SUBSYS for short-term pain that you would expect to go away in a few days, such as:
6. Never give SUBSYS to anyone else, even if they have the same symptoms you have. It may harm them or even cause death.

- As your dose is adjusted, your
healthcare provider will tell you whether your dose of SUBSYS is 1 or 2 sprays

- If you are still in pain after 30 minutes, take 1 more dose of SUBSYS as instructed by your healthcare provider.
- Do nottake more than 2 doses of SUBSYS for an episode of breakthrough cancer pain. If your breakthrough pain does not get better after the second dose of SUBSYS, call your healthcare provider for instructions. Do not use another dose of SUBSYS at this time.
- Wait at least 4 hoursbefore treating a new episode of breakthrough cancer pain with SUBSYS.
- Keep taking your around-the-clock opioid pain medicine while taking SUBSYS.
- If you have more than 4 episodes of breakthrough cancer pain in a day, talk to your healthcare provider. The dose of your around-the-clock opioid pain medicine may need to be adjusted.

What are the possible side effects of SUBSYS?
SUBSYS can cause serious side effects, including:
1. Breathing problems that can become life-threatening. See “What is the most important information I should know about SUBSYS?”
- Call your healthcare provider or get emergency medical
help right away if you:
- have drowsiness with slowed breathing
- have trouble breathing
- have shallow breathing (little chest movement with breathing)

2. Decreased blood pressure. This can make you feel dizzy or lightheaded if you get up too fast from sitting or lying down.
3. Physical dependence. Do not stop using SUBSYS or any other opioid, without talking to your healthcare provider.You could become sick with withdrawal symptoms because your body has become used to these medicines. Physical dependency is not the same as drug addiction.
4. A chance of abuse or addiction.This chance is higher if you are or have ever been addicted to or abused other medicines, street drugs, or alcohol, or if you have a history of mental health problems.
The most common side effects of SUBSYS are:
- shortness of breath
