Frequently Asked Questions about TAPENAX ER 50

TAPENAX ER 50 is an extended-release medication containing Tapentadol, a strong painkiller that belongs to the class of opioids. It is prescribed for adults to manage moderate to severe chronic pain.

What is TAPENAX ER 50 used for?

TAPENAX ER 50 is used to relieve moderate to severe chronic pain that requires daily, around-the-clock, long-term opioid treatment and for which other treatment options are inadequate. This includes chronic pain and neuropathic pain associated with diabetic peripheral neuropathy (DPN). It is not intended for "as-needed" pain relief or mild pain.

How does TAPENAX ER 50 work?

Tapentadol, the active ingredient in TAPENAX ER 50, is a centrally-acting analgesic with a dual mechanism of action. It works by acting as a mu-opioid receptor (MOR) agonist and by inhibiting norepinephrine reuptake (NRI). This dual action helps to reduce the sensation of pain by interfering with how nerve signals transmit pain between the brain and the body, making it effective for both nociceptive and neuropathic pain.

What is the usual dosage for TAPENAX ER 50?

For adults not currently taking opioid medications (opioid-naive patients), the usual starting dose for extended-release tapentadol is 50 milligrams (mg) taken twice a day, approximately every 12 hours. Your doctor may adjust the dose based on your response and tolerability, but the daily dose usually should not exceed 500 mg. It is crucial to swallow the extended-release tablets whole; they should not be crushed, chewed, or dissolved, as this can lead to rapid absorption and potentially fatal overdose.

What are the possible side effects of TAPENAX ER 50?

Common side effects include constipation, nausea, vomiting, headache, dizziness, drowsiness, dry mouth, increased sweating, and fatigue.

Serious side effects can include:

• Respiratory depression: Slowed or shallow breathing, which can be life-threatening.
• Addiction and dependence: Tapentadol has a high potential for abuse and addiction, even at prescribed dosages.
• Serotonin syndrome: A potentially life-threatening condition that can occur when taken with certain other medications.
• Low blood pressure (hypotension).
• Seizures.

Contact your doctor immediately if you experience any serious side effects.

Is TAPENAX ER 50 safe during pregnancy or breastfeeding?

Pregnancy: TAPENAX ER 50 should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Prolonged use during pregnancy can lead to neonatal opioid withdrawal syndrome in the newborn.

Breastfeeding: Tapentadol passes into breast milk and can cause drowsiness, difficulty feeding, and breathing problems in the infant. It is generally not recommended during breastfeeding, especially for newborns or premature infants. If use is necessary, infants should be closely monitored for signs of increased sleepiness, difficulty breastfeeding, breathing difficulties, or limpness.

Can TAPENAX ER 50 be taken with other medications?

TAPENAX ER 50 can interact with several medications, potentially increasing the risk of serious side effects.

• Monoamine Oxidase Inhibitors (MAOIs): Do not take TAPENAX ER 50 if you are taking or have taken an MAOI within the past 14 days, as this combination can lead to severe and life-threatening reactions like serotonin syndrome or hypertensive crisis.
• Other Central Nervous System (CNS) Depressants: Combining TAPENAX ER 50 with alcohol, benzodiazepines, other opioids, sedatives, muscle relaxants, certain antidepressants, or antihistamines can significantly increase the risk of severe respiratory depression, profound sedation, and coma.
• Serotonergic Drugs: Co-administration with other medications that affect serotonin levels (e.g., SSRIs, SNRIs) can increase the risk of serotonin syndrome.

Always inform your doctor about all medications, supplements, and herbal products you are taking to avoid potential interactions.

What precautions should be taken with TAPENAX ER 50?

• Addiction and Misuse Risk: Due to its opioid nature, TAPENAX ER 50 has a high risk of addiction, abuse, and misuse, which can lead to overdose and death. It is essential to take it exactly as prescribed and store it securely.
• Respiratory Problems: Use with extreme caution, or avoid, in individuals with severe asthma or other significant breathing difficulties due to the risk of respiratory depression.
• Liver and Kidney Impairment: If you have liver or kidney disease, your doctor may need to adjust your dose or determine if this medication is suitable for you.
• Drowsiness/Dizziness: TAPENAX ER 50 can cause dizziness, drowsiness, and affect your coordination. Avoid driving or operating heavy machinery until you know how the medication affects you.
• Withdrawal: Do not stop taking TAPENAX ER 50 abruptly. If discontinuing the medication, your doctor will slowly reduce the dose to prevent withdrawal symptoms.
• Opioid-Induced Hyperalgesia: In some cases, this medication can paradoxically increase pain sensitivity, especially at higher doses.

What happens if a dose of TAPENAX ER 50 is missed?

If you miss a dose of TAPENAX ER 50, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for the missed one.

How should TAPENAX ER 50 be stored?

Store TAPENAX ER 50 in a well-closed container at room temperature, typically between 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit). Protect it from light and moisture. It is critical to keep this medicine out of the reach of children and pets. Dispose of any unused or expired medication properly, ideally by returning it to a pharmacy or following local guidelines for opioid disposal.
