What should I watch for while using this medication?
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.
This medication may affect your coordination, reaction time, or judgment. Do not drive or operate machinery until you know how this medication affects you. Sit up or stand slowly to reduce the risk of dizzy or fainting spells. Drinking alcohol with this medication can increase the risk of these side effects.
Do not take other medications that contain acetaminophen with this medication. Always read labels carefully. If you have questions, ask your care team or pharmacist.
If you take too much acetaminophen, get medical help right away. Too much acetaminophen can be very dangerous and cause liver damage. Even if you do not have symptoms, it is important to get help right away.
What are the most serious risks of this medication?
This medication has acetaminophen in it. Taking too much acetaminophen can cause serious liver injury and death. It is important that you do not take more than 4,000 mg of acetaminophen in one day. Many medications for pain and fever contain acetaminophen. It is important to check package labels. Do not take more than one medication that has acetaminophen in it at the same time. Talk to your care team about all the medications you take, both prescription and over-the-counter. They can help you make sure you are not taking too much. Liver problems and alcohol use while taking acetaminophen can increase the risk of liver injury. Seek medical help right away if you think you have taken too much acetaminophen. It is important even if you do not have symptoms. Symptoms of liver injury include feeling weak or tired, pain in the right upper side of the belly, loss of appetite, nausea, and yellowing of the skin or eyes.
