Tapentadol may cause serious or life-threatening breathing problems, especially at the beginning of your treatment and any time your dose is increased. Your doctor will adjust your dose to control your pain and decrease the risk that you will experience serious breathing problems. Tell your doctor if you have or have ever had slowed breathing or asthma. Your doctor will probably tell you not to take tapentadol. Also tell your doctor if you have or have ever had lung disease such as chronic obstructive pulmonary disease (COPD; a group of lung diseases that includes chronic bronchitis and emphysema), a head injury, or any condition that increases the amount of pressure in your brain. The risk that you will develop breathing problems may be higher if you are an older adult or are weakened or malnourished due to disease. If you experience any of the following symptoms, call your doctor immediately or get emergency medical treatment: slowed breathing, long pauses between breaths, or shortness of breath.
Taking certain other medications during your treatment with tapentadol may increase the risk that you will experience breathing problems or other serious, life threatening side effects. Tell your doctor if you are taking or plan to take any of the following medications: other narcotic pain medications; medications for mental illness or nausea; muscle relaxants; sedatives; sleeping pills; or tranquilizers.
Drinking alcohol, taking prescription or nonprescription medications that contain alcohol, or using street drugs during your treatment with tapentadol increases the risk that you will experience serious, life-threatening side effects. Do not drink alcohol, take prescription or non-prescription medications that contain alcohol, or use street drugs during your treatment with tapentadol.
Tapentadol may be habit-forming. Do not take more of it, take it more often, or take it in a different way than directed by your doctor. Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications, or if you have or have ever had depression or another mental illness. There is a greater risk that you will overuse tapentadol if you have or have ever had any of these conditions.
Do not allow anyone else to take your medication. Tapentadol may harm or cause death to other people who take your medication, especially children. Keep tapentadol in a safe place so that no one else can take it accidentally or on purpose. Be especially careful to keep tapentadol out of the reach of children. Keep track of how many tablets or extended-release tablets are left so you will know if any medication is missing. Flush any tablets or extended-release tablets that are outdated or no longer needed down the toilet so that others will not take them.
If you are taking the extended-release tablets, swallow them whole; do not chew, break, divide, crush, or dissolve them. If you swallow broken, chewed, crushed, or dissolved extended-release tablets, you may receive too much tapentadol at once instead of slowly over 12 hours. This may cause serious problems, including overdose and death.
Tell your doctor if you are pregnant or plan to become pregnant. If you take tapentadol regularly during your pregnancy, your baby may experience life-threatening withdrawal symptoms after birth. Tell your baby's doctor right away if your baby experiences any of the following symptoms: irritability, hyperactivity, abnormal sleep, high-pitched cry, uncontrollable shaking of a part of the body, vomiting, diarrhea, or failure to gain weight.
Talk to your doctor about the risks of taking tapentadol.
If you are taking tapentadol extended-release tablets, your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin your treatment and each time you fill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website ( Web Site) or the manufacturer's website to obtain the Medication Guide.
Tapentadol tablets are used to treat moderate to severe acute pain (pain that begins suddenly, has a specific cause, and is expected to go away when the cause of the pain is healed). Tapentadol extended-release tablets are used to treat severe neuropathic pain (pain caused by nerve damage) in people who have diabetes. Tapentadol extended-release tablets are only used to treat people who are expected to need medication around-the-clock to relieve pain that cannot be controlled by the use of other pain medications. Tapentadol is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain.
Tapentadol comes as a tablet and an extended-release (long acting) tablet to take by mouth. The tablets are usually taken with or without food every 4 to 6 hours as needed. If you are taking tapentadol tablets, your doctor may tell you that you may take a second dose as soon as 1 hour after the first dose on your first day of treatment if needed to treat your pain. Do not take extra doses at any other time during your treatment and do not ever take extra doses of the extended-release tablets. The extended-release tablets are taken once every 12 hours. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take tapentadol exactly as directed.
If you are taking the extended-release tablets, swallow them one at a time with plenty of water. Swallow each tablet right after you put it in your mouth.
Your doctor will probably start you on a low dose of tapentadol and gradually increase your dose until your pain is controlled. Your doctor may adjust your dose at any time during your treatment if your pain is not controlled. If you feel that your pain is not controlled, call your doctor. Do not change the dose of your medication without talking to your doctor.
After you take tapentadol for a period of time, your body may become used to the medication. If this happens, your doctor may need to increase your dose of medication to control your pain. Talk to your doctor about how you are feeling during your treatment with tapentadol.
Do not stop taking tapentadol without talking to your doctor. Your doctor will probably decrease your dose gradually. If you suddenly stop taking tapentadol, you may experience withdrawal symptoms such as restlessness; anxiety; irritability; teary eyes; yawning; chills; sweating; difficulty falling asleep or staying asleep; shivering; uncontrollable shaking of a part of your body; muscle, back, or joint pain; weakness; nausea; vomiting; diarrhea; stomach cramps; loss of appetite; runny nose, sneezing, or coughing; hair on your skin standing on end; fast breathing; fast heartbeat; widening of the pupils (black circles in the middle of the eyes); or hallucinations (seeing things or hearing voices that do not exist).
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
