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).
