What Is This Medicine?

Simply put, this medicine is a powerful prescription pain reliever. It contains two main active ingredients that work together to ease severe pain when other treatments do not work.

The first active ingredient is benzhydrocodone. This component belongs to a class of medicines called opioids. Opioids travel through your body to block pain signals in your brain so you feel less discomfort.

The second active ingredient is acetaminophen. You likely know this ingredient by its more common name, paracetamol. Combining these two ingredients gives the medicine a strong ability to manage intense pain.

The most important rule is that you should only use this medicine if your doctor prescribes it. Follow their exact directions and use it only for the prescribed time. Never buy it from unverified sources or share it with anyone else.

Things to Tell Your Doctor Before Taking This Medicine

Important Precautions While Taking the Medicine

1. Tolerance and Addiction:

When you take this medicine for a long time, your body may get used to it. This means your usual dose might not relieve pain as well as before, which is called tolerance. Tolerance is a normal bodily response and is different from addiction. Addiction involves using a drug for emotional highs without medical need. Always take your medicine strictly for medical reasons.

2. Avoid Extra Acetaminophen:

3. No Alcohol Use:

Do not drink alcohol or eat products containing alcohol while taking this medicine. Combining alcohol with this prescription greatly increases your risk of severe dizziness, extreme drowsiness, and dangerous breathing problems.

4. Drowsiness and Focus:

This medicine can make you feel sleepy, dizzy, or less alert. Until you know how the medicine affects you, avoid driving, operating machinery, or doing tasks that require sharp focus.

5. Managing Constipation:

Opioid painkillers often cause constipation. Drink plenty of fluids and eat high-fiber foods like fresh fruits and vegetables. If you do not have a bowel movement for two to three days, speak with your doctor.
