Drug class: Narcotic analgesic combinations

Medically reviewed by Drugs.com. Last updated on Jul 17, 2022.

Oral route(Solution)

Hydrocodone bitartrate and acetaminophen oral solution has the potential for addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient's risk before prescribing, and monitor for development of these behaviors and 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. Serious, life-threatening, or fatal respiratory depression may occur. Monitor closely, especially upon initiation or following a dose increase. Accidental ingestion of hydrocodone bitartrate and acetaminophen oral solution, especially by children, can result in a fatal overdose of hydrocodone bitartrate and acetaminophen. Prolonged use of hydrocodone bitartrate and acetaminophen oral solution during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated. Monitor patients receiving hydrocodone bitartrate and acetaminophen oral solution and any CYP3A4 inhibitor or inducer for signs of respiratory depression or sedation. Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death, most often with the use of acetaminophen at doses that exceed 4000 mg/day, and involving more than 1 acetaminophen-containing product. Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing for patients with inadequate alternative treatment options. Limit dosages and durations to the minimum required and follow patients for signs and symptoms of respiratory depression and sedation .

Therapeutic Class: Opioid/Acetaminophen Combination

Chemical Class: Hydrocodone

## Uses for Anexsia

Hydrocodone and acetaminophen combination is used to relieve pain severe enough to require opioid treatment and when other pain medicines did not work well enough or cannot be tolerated.

Acetaminophen is used to relieve pain and reduce fever in patients. It does not become habit-forming when taken for a long time. But acetaminophen may cause other unwanted effects when taken in large doses, including liver damage.

Hydrocodone belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain, and stops or prevents cough.

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 under a restricted distribution program called the Opioid Analgesic REMS (Risk Evaluation and Mitigation Strategy) program.

## Before using Anexsia

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 and acetaminophen combination capsules and tablets in the pediatric population. Safety and efficacy have not been established.

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of hydrocodone and acetaminophen combination oral solution in children 2 years of age and older. However, safety and efficacy have not been established in children younger than 2 years of age.

### Geriatric

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

### 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 Anexsia

This section provides information on the proper use of a number of products that contain hydrocodone and acetaminophen. It may not be specific to Anexsia. 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. Large amounts of acetaminophen may cause liver damage.

It is very important that you understand the rules of the Opioid Analgesic REMS program to prevent addiction, abuse, and misuse of hydrocodone and acetaminophen combination. This medicine should also come with a Medication Guide and patient information leaflet. 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.

Measure the oral liquid with a marked measuring spoon, oral syringe, dropper, or medicine cup. The average household teaspoon may not hold the right amount of liquid.

This combination medicine contains acetaminophen (Tylenol®). Carefully check the labels of all other medicines you are using, because they may also contain acetaminophen. It is not safe to use more than 4 grams (4,000 milligrams) of acetaminophen in one day (24 hours).

Detailed Anexsia dosage information

## Precautions while using Anexsia

It is very important that your doctor check your or your child's progress while 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 or your child should continue to take it. Blood and urine tests may be needed to check for unwanted effects.

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

It is against the law and dangerous for anyone else to use your medicine. Keep your unused tablets in a safe and secure place. People who are addicted to drugs might want to steal this medicine.

This medicine will add to the effects of alcohol and other CNS depressants (medicines that can make you drowsy or 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 (numbing medicines), including some dental anesthetics. Also, there may be a greater risk of liver damage if you drink three or more alcoholic beverages while you are taking acetaminophen. Do not drink alcoholic beverages, and check with your doctor before taking any of these medicines while you are using this medicine.

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.

If you think you or someone else may have taken an overdose of this medicine, get emergency help at once. Your doctor may also give naloxone to treat an overdose. Signs of an overdose include: cold, clammy skin, coughing that sometimes produces a pink frothy sputum, dark urine, difficult or trouble breathing, irregular, fast or slow, or shallow breathing, nausea, vomiting, pain in the upper stomach, pale or blue lips, fingernails, or skin, pinpoint pupils of the eyes, or yellow eyes or skin.

This medicine may cause sleep-related breathing problems (eg, sleep apnea, sleep-related hypoxemia). Your doctor may decrease your dose if you have sleep apnea (stop breathing for short periods during sleep) while using this medicine.

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.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, unusual tiredness or weakness, or yellow eyes or skin. These could be symptoms of a serious liver problem.

This medicine may cause serious skin reactions (eg, acute generalized exanthematous pustulosis, Stevens-Johnson syndrome, toxic epidermal necrolysis). Check with your doctor right away if you have blistering, peeling, or loosening of the skin, chills, cough, diarrhea, itching, joint or muscle pain, red irritated eyes, red skin lesions, often with a purple center, sore throat, sores, ulcers, or white spots in the mouth or on the lips, or unusual tiredness or weakness.

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.

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 narcotics for a long time can cause severe constipation. To prevent this, your doctor may direct you or your child 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.

Before you or your child have any medical tests, tell the medical doctor in charge that you are taking this medicine. The results of certain tests may be affected by this medicine.

Do not change your dose or suddenly stop using this medicine without first checking with your doctor. Your doctor may want you or your child to gradually reduce the amount you are using before stopping it completely. This may help prevent worsening of your condition and reduce the possibility of withdrawal symptoms, including stomach cramps, anxiety, fever, nausea, runny nose, sweating, tremors, or trouble with sleeping.

Using this medicine while you are pregnant may cause serious unwanted effects, including neonatal withdrawal syndrome in your newborn baby. Tell your doctor right away if your child has an abnormal sleep pattern, diarrhea, a high-pitched cry, irritability, shakiness or tremors, sneezing, weight loss, vomiting, yawning, or failure to gain weight. Check with your doctor right away if you think you are pregnant or if you plan to become pregnant while using this medicine.

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 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.
