# Vantrela ER (Oral)

Generic name: hydrocodone (oral route) [ hye-droe-KOE-done-bye-TAR-trate ]
Drug class: Opioids (narcotic analgesics)

Medically reviewed by Drugs.com. Last updated on Sep 24, 2022.

Oral route(Capsule, Extended Release)

Prior to prescribing hydrocodone, assess each patient's risk for opioid addiction, abuse, and misuse, and regularly monitor all patients for opioid addiction behaviors or conditions. To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse, and misuse, the Food and Drug Administration (FDA) has required a Risk Evaluation and Mitigation Strategy (REMS) for these products. Monitor for respiratory depression, which can be serious, life-threatening, or fatal, especially during initiation or following a dose increase. Instruct patients to swallow extended release forms whole to avoid potentially fatal overdose. Accidental ingestion of hydrocodone can result in a fatal overdose, especially in children. If prolonged opioid use is necessary during pregnancy, advise patient of potential risk of life-threatening neonatal opioid withdrawal syndrome and ensure appropriate treatment will be available. Use with CYP3A4 inhibitors or inducers may change hydrocodone plasma levels resulting in prolonged adverse effects or potentially fatal respiratory depression; monitoring is recommended. Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing for patients with inadequate alternative treatment options, limit dosage and duration to the minimum required, and monitor for respiratory depression and sedation. Alcoholic beverages or medications containing alcohol should be avoided due to the potential for increased hydrocodone plasma levels and a potentially fatal overdose .

Oral route(Tablet, Extended Release)

Addiction, Abuse, and MisuseHydrocodone extended-release (ER) exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient's risk prior to prescribing Hydrocodone ER, and monitor all patients regularly for the development of these behaviors or conditions.Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS)To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse and misuse, the Food and Drug Administration (FDA) has required a REMS for these products. Under the requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to healthcare providers. Healthcare providers are strongly encouraged to: complete a REMS-compliant education program, counsel patients and/or their caregivers, with every prescription, on safe use, serious risks, storage, and disposal of these products, emphasize to patients and their caregivers the importance of reading the Medication Guide every time it is provided by their pharmacists, and consider other tools to improve patient, household, and community safety.Life-Threatening Respiratory DepressionSerious, life-threatening, or fatal respiratory depression may occur with use of Hydrocodone ER. Monitor for respiratory depression, especially during initiation of Hydrocodone ER or following a dose increase. Instruct patients to swallow hydrocodone bitartrate ER tablets whole; crushing, chewing, or dissolving hydrocodone bitartrate tablets can cause rapid release and absorption of a potentially fatal dose of hydrocodone bitartrate.Accidental IngestionAccidental ingestion of even one dose of Hydrocodone ER, especially by children, can result in a fatal overdose of Hydrocodone ER.Neonatal Opioid Withdrawal SyndromeProlonged use of Hydrocodone ER during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.Cytochrome P450 3A4 InteractionThe concomitant use of Hydrocodone ER with all cytochrome P450 3A4 inhibitors may result in an increase in Hydrocodone plasma concentrations, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression. In addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an increase in Hydrocodone plasma concentration. Monitor patients receiving Hydrocodone ER and any CYP3A4 inhibitor or inducer.Risks from Concomitant Use with Benzodiazepines or Other CNS DepressantsReserve concomitant prescribing of Hydrocodone ER and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation .

## Uses for Vantrela ER

Hydrocodone is used to relieve pain in opioid-tolerant patients severe enough to require around-the-clock pain relief for a long period of time. It should not be used if you need pain medicine for just a short time, such as when recovering from surgery. Do not use this medicine to relieve mild pain. This medicine should not be used to treat pain that you only have once in a while or "as needed".

Hydrocodone belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain.

When hydrocodone is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.

This medicine is available only with your doctor's prescription. Hysingla® and Zohydro® are available only under a restricted distribution program called the Opioid Analgesic REMS (Risk Evaluation and Mitigation Strategy) program.

## Before using Vantrela ER

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

### Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

### Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of hydrocodone in the pediatric population. Safety and efficacy have not been established.

### Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of hydrocodone in the elderly. However, elderly patients are more likely to have confusion and severe drowsiness and age-related liver, kidney, heart, or lung problems, which may require caution and an adjustment in the dose for patients receiving hydrocodone.

### Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

### Interactions with medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

## Proper use of Vantrela ER

This section provides information on the proper use of a number of products that contain hydrocodone. It may not be specific to Vantrela ER. Please read with care.

Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. This is especially important for elderly patients, who may be more sensitive to the effects of pain medicines. If too much of this medicine is taken for a long time, it may become habit-forming (causing mental or physical dependence) or cause an overdose.

It is very important that you understand the rules of the Opioid Analgesic REMS program to prevent addiction, abuse, and misuse of oxycodone. This medicine should also come with a Medication Guide. Read and follow these instructions carefully. Read it again each time you refill your prescription in case there is new information. Ask your doctor if you have any questions.

If you are using the extended-release capsules or extended-release tablets:

Detailed Vantrela ER dosage information

## Precautions while using Vantrela ER

It is very important that your doctor check your progress while you are using this medicine, especially within the first 24 to 72 hours of treatment. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it. Blood and urine tests may be needed to check for unwanted effects.

This medicine may cause a serious type of allergic reaction called anaphylaxis, which can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

Do not use this medicine if you have used an MAO inhibitor (MAOI) (eg, isocarboxazid [Marplan®], linezolid [Zyvox®], phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]) within the past 14 days.

This medicine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.

This medicine will add to the effects of alcohol and other CNS depressants. CNS depressants are medicines that slow down the nervous system, which may cause drowsiness or make you less alert. Some examples of CNS depressants are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicine, other prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. This effect may last for a few days after you stop using this medicine. Check with your doctor before taking any of these medicines while you are using this medicine.

This medicine may make you dizzy, drowsy, or lightheaded. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

Using too much hydrocodone may cause an overdose, which can be life-threatening. Signs of an overdose include: change in consciousness, cold, clammy skin, dark urine, difficult or trouble breathing, irregular, fast or slow, or shallow breathing, loss of consciousness, nausea or vomiting, pain in the upper stomach, pale or blue lips, fingernails, or skin, pinpoint pupils of the eyes, sleepiness or unusual drowsiness, or yellow eyes or skin. In case of an overdose, call your doctor right away. Your doctor may also give naloxone to treat an overdose.

This medicine may cause adrenal gland problems. Check with your doctor right away if you have darkening of the skin, diarrhea, dizziness, fainting, loss of appetite, mental depression, nausea, skin rash, unusual tiredness or weakness, or vomiting.

Dizziness, lightheadedness, or fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve dizziness or lightheadedness.

Using narcotics for a long time can cause severe constipation. To prevent this, your doctor may direct you to take laxatives, drink a lot of fluids, or increase the amount of fiber in your diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.

Contact your doctor right away if you have any changes to your heart rhythm. You might feel dizzy or faint, or you might have a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you or anyone in your family has ever had a heart rhythm problem including QT prolongation.

Do not suddenly stop or change your dose without first checking with your doctor. You may be directed to gradually reduce the amount you are using before stopping treatment completely, or to take another narcotic for a while, to lessen the chance of withdrawal side effects (eg, anxiety, fever, nausea, runny nose, stomach cramps, sweating, tremors, or trouble with sleeping.

Check with your doctor right away if you have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be symptoms of a serious condition called serotonin syndrome. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.

Using this medicine while you are pregnant may cause neonatal withdrawal syndrome in your newborn babies. Tell your doctor right away if your baby has an abnormal sleep pattern, diarrhea, a high-pitched cry, irritability, shakiness or tremors, weight loss, vomiting, or fails to gain weight.

For nursing mothers:

- Talk to your doctor if you have any questions about taking hydrocodone or about how this medicine may affect your baby.
- Call your doctor if you become extremely tired and have difficulty caring for your baby.
- Your baby should generally nurse every 2 to 3 hours and should not sleep for more than 4 hours at a time.
- Check with your doctor or hospital emergency room immediately if your baby shows signs of increased sleepiness (more than usual), difficulty breastfeeding, difficulty breathing, or limpness. These may be symptoms of an overdose and need immediate medical attention.

Using too much of this medicine may cause infertility (unable to have children). Talk with your doctor before using this medicine if you plan to have children.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
