How does this medication work? What will it do for me?
Tapentadol belongs to a class of pain relievers known as opioid analgesics (also known as narcotic analgesics) that act on the central nervous system. It relieves pain by acting on specific nerve cells of the spinal cord and brain.
It is used to treat moderate to severe pain in adults.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here.

How should I use this medication?
The recommended starting dose (for people who are not currently taking opioid pain relievers) is 50 mg to 100 mg every 4 to 6 hours depending on the level of your pain. The dose may be increased depending on how the medication is tolerated and how well it works for your pain. The maximum total daily dose on the first day is 700 mg. On the second and subsequent days of treatment, the maximum total daily dose is 600 mg.
If you have been taking another opioid medication, the starting dose of tapentadol may be higher, depending on the dose of the other medication. Your doctor will determine the most appropriate starting dose.
You may take the tablets on an empty stomach or with meals. Always swallow the tablet whole with sufficient liquid. Do not crush, break, chew or dissolve the tablets, as this can be dangerous and potentially cause serious harm or death.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
Stopping the medication suddenly may cause withdrawal symptoms (such as restlessness, irritability, nausea and vomiting, diarrhea, sweating, chills, muscle aches, or watery eyes and nose). Do not stop taking this medication without checking with your doctor first. Your doctor will advise you on how to stop the medication safely.
It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Abdominal (stomach) conditions: As with other narcotic medications, tapentadol may make the diagnosis of abdominal conditions more difficult or it may worsen these conditions. If you have abdominal problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Accidental use: When tapentadol is used by anyone other than the person for whom it was prescribed, the effects of the medication may be fatal. Children are especially at risk. Keep this medication out of sight and reach of children.
Addiction: Tapentadol may lead to physical and psychological addiction. Tell your doctor if you (or a family member) have ever abused or been dependent on alcohol, prescription medications, or street drugs.
Adrenal gland problems: People who take opioid medications, such as tapentadol, for more than 1 month may experience symptoms of decreased adrenal gland function. The adrenal gland produces certain hormones that keep the body functioning normally. If you experience nausea or vomiting, decreased appetite, and feelings of tiredness, weakness, or dizziness, talk to your doctor.
Alcohol and other medications that cause drowsiness: People taking this medication should not combine it with alcohol and should avoid combining it with other medications, such as narcotic pain relievers, sedatives, or anxiety medications, that cause drowsiness. Doing so can cause additive drowsiness and reduced breathing, as well as other side effects, which can be dangerous and possibly fatal.
Breathing: Tapentadol can suppress breathing. This effect on breathing may be more pronounced for people with breathing problems, brain damage, or who are taking other medications that suppress breathing (e.g., codeine, morphine). If you have breathing problems, such as COPD, asthma or respiratory depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Constipation: Constipation happens frequently while taking opioid (narcotic) pain relievers on a regular basis. Your doctor will discuss the use of stimulant laxatives, stool softeners, and other measures to be used as required.
Dependence and withdrawal: Physical dependence (a need to take regular doses to prevent physical symptoms) has been associated with this medication. Severe withdrawal symptoms may be experienced (e.g., seizures) if the dose is significantly reduced or suddenly stopped. Withdrawal symptoms include irritability, nervousness, sleep problems, agitation, tremors, diarrhea, abdominal cramps, vomiting, memory impairment, headache, muscle pain, extreme anxiety, tension, restlessness, and confusion. Reducing the dose gradually under medical supervision can help prevent or decrease these withdrawal symptoms.
Drowsiness/reduced alertness: This medication may cause drowsiness or reduced alertness. Avoid driving or engaging in other activities requiring alertness unless and until you know how the medication affects you. Alcohol and antianxiety medications can increase the drowsiness caused by this medication.
Head injury: Tapentadol can cause increased pressure inside the head. If you have acute head injuries or other conditions which increase their intracranial pressure (pressure inside the head) discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney function: The safety and effectiveness of tapentadol has not been established for people with reduced kidney function. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication.
If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.
Overdose: If you experience the following symptoms after taking very high doses, seek medical help immediately:
- breathing that is stopped or dangerously slow or shallow
- disturbed consciousness or coma (deep unconsciousness)
- drop in blood pressure
- fast heartbeat
- pin-point pupils
Pancreatitis: If you have a history of pancreatitis (inflammation of the pancreas), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Report signs of pancreatitis such as abdominal pain on the upper left side, back pain, nausea, fever, chills, rapid heartbeat, or swollen abdomen to your doctor immediately.
Seizures: There have been reports of seizures occurring with tapentadol. Seizures are more likely to occur when higher doses of this medication are taken. If you have a history of epilepsy or medical conditions that increase the risk of seizures, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Serotonin Syndrome: Severe reactions are possible when tapentadol is combined with other medications that act on serotonin, such as tricyclic antidepressants and serotonin reuptake inhibitors, medications used to treat depression. These combinations must be avoided. Symptoms of a reaction may include muscle rigidity and spasms, difficulty moving, changes in mental state including delirium and agitation. Coma and death are possible.
Pregnancy: This medication should not be used during pregnancy, prior to or during labour. Infants born to mothers who have taken tapentadol during pregnancy have been born with signs of narcotic withdrawal. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication can pass into breast milk. If you are a breast-feeding mother and are taking tapentadol, it may cause life-threatening breathing problems for your baby. This medication is not recommended for breast-feeding mothers.
Children: The safety and effectiveness of using this medication have not been established for children. Tapentadol is not recommended for use by people under 18 years of age.
Seniors: Seniors are at an increased risk of experiencing side effects of tapentadol. Your doctor may prescribe a lower dose than those recommended here.
