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 the 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 the medication for a long time.
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 non-medical 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.
