Tell your care team if your pain does not go away, if it gets worse, or if you have new or a different type of pain. You may develop tolerance to this medication. Tolerance means that you will need a higher dose of the medication for pain relief. Tolerance is normal and is expected if you take this medication for a long time.
There are different types of medications for pain. If you take more than one type at the same time, you may have more side effects. Give your care team a list of all medications you use. They will tell you how much medication to take. Do not take more medication than directed. Call emergency services right away if you have problems breathing.
Do not suddenly stop taking your medication because you may develop a severe reaction. Your body becomes used to the medication. This does NOT mean you are addicted. Addiction is a behavior related to getting and using a medication for a nonmedical reason. If you have pain, you have a medical reason to take pain medication. Your care team will tell you how much medication to take. If your care team wants you to stop the medication, the dose will be slowly lowered over time to avoid any side effects.
Talk to your care team about naloxone and how to get it. Naloxone is an emergency medication used for an opioid overdose. An overdose can happen if you take too much opioid. It can also happen if an opioid is taken with some other medications or substances, like alcohol. Know the symptoms of an overdose, like trouble breathing, being unusually tired or sleepy, or not being able to respond or wake up. Make sure to tell caregivers and close contacts where it is stored. Make sure they know how to use it. After naloxone is given, you must get emergency help right away. Naloxone is a temporary treatment. Repeat doses may be needed.
Children may be at higher risk for side effects. If your child has slow breathing, noisy breathing, confusion, or unusual sleepiness, stop giving this medication and call emergency services right away.
