Benzhydrocodone and Acetaminophen

pronounced as (benz hye droe koe' done) (a set a mee' noe fen)

Brand Name(s): Apadaz®

Why is this medicine prescribed?

The combination of benzhydrocodone and acetaminophen is used to relieve severe, acute pain (pain that begins suddenly, has a specific cause, and is expected to go away when the cause of the pain is healed) in people who are expected to need an opioid pain medication and whose pain cannot be relieved by other non-opioid pain medications. Benzhydrocodone is in a class of medications called opiate (narcotic) analgesics. It works by changing the way the brain and nervous system respond to pain. Acetaminophen is in a class of medications called analgesics (pain relievers) and antipyretics (fever reducers). When acetaminophen is used in combination with benzhydrocodone to treat pain, it works by changing the way the body senses pain.

Are there other uses for this medicine?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medicine be used?

You should not take more than 12 tablets in 24 hours. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take benzhydrocodone and acetaminophen exactly as directed.

Your doctor may adjust your dose of benzhydrocodone and acetaminophen during your treatment, depending on how well your pain is controlled and on the side effects that you experience.

Do not take more of it or take it more often than prescribed by your doctor.

What special dietary instructions should I follow?

Unless your doctor tells you otherwise, continue your normal diet.

What should I do if I forget to take a dose?

This medication is usually taken as needed. If your doctor has told you to take benzhydrocodone and acetaminophen regularly, take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

What should I do in case of overdose?

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help . If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

While taking benzhydrocodone and acetaminophen, you should talk to your doctor about having a rescue medication called naloxone readily available (e.g., home, office). Naloxone is used to reverse the life-threatening effects of an overdose. It works by blocking the effects of opiates to relieve dangerous symptoms caused by high levels of opiates in the blood. Your doctor may also prescribe you naloxone if you are living in a household where there are small children or someone who has abused street or prescription drugs. You should make sure that you and your family members, caregivers, or the people who spend time with you know how to recognize an overdose, how to use naloxone, and what to do until emergency medical help arrives. Your doctor or pharmacist will show you and your family members how to use the medication. Ask your pharmacist for the instructions or visit the manufacturer's website to get the instructions. If symptoms of an overdose occur, a friend or family member should give the first dose of naloxone, call 911 immediately, and stay with you and watch you closely until emergency medical help arrives. Your symptoms may return within a few minutes after you receive naloxone. If your symptoms return, the person should give you another dose of naloxone. Additional doses may be given every 2 to 3 minutes, if symptoms return before medical help arrives.

Symptoms of overdose may include:

  • slowed or shallow breathing
  • difficulty breathing
  • excessive sleepiness
  • unable to respond or wake up
  • limp or weak muscles
  • cold, clammy skin
  • narrowing or widening of the pupils (dark circle in the eye)
  • slowed heartbeat
  • unusual snoring
  • nausea
  • vomiting

What should I know about storage and disposal of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children, and in a location that is not easily accessible by others, including visitors to the home. Store it at room temperature and away from excess heat and moisture (not in the bathroom). You must immediately dispose of any medication that is outdated or no longer needed through a medicine take-back program. If you do not have a take-back program nearby or one that you can access promptly, flush any medication that is outdated or no longer needed down the toilet so that others will not take it. Talk to your pharmacist about the proper disposal of your medication.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
