Home » Blog » What is a White M366 Pill?

The M366 pill is a widely prescribed pain medication that contains acetaminophen and hydrocodone bitartrate. While acetaminophen is an over-the-counter pain reliever, hydrocodone is an opioid that is only available by prescription. When combined, these substances can relieve severe pain and chronic pain.

Even though the white oval M366 pill can offer pain relief, it is known for being habit-forming and addictive. When abused, this medication can lead to mind-altering effects like euphoria, calmness, and drowsiness. Because it contains an opioid, you could develop a severe substance use disorder if you abuse M366 pills.

Thankfully, it is possible to recover from hydrocodone addiction. With a combination of medical detox, medication-assisted treatment, and evidence-based therapies, you can recover from opioid addiction. The Mandala Healing Center is here to offer you the tools and support you need to overcome M366 pill addiction and find a replacement to manage your chronic pain condition.

What is the M366 Pill?

The M366 pill combines two active ingredients: hydrocodone bitartrate and acetaminophen. It is prescribed to treat severe pain after an injury or surgery and chronic pain from conditions like arthritis. Because it contains an opioid analgesic, it manages pain by reducing pain signals sent to your brain.

This substance is a central nervous system depressant, which means on top of managing pain, it slows down activity in your brain and body. If you abuse the M366 pill, you might experience a high that is characterized by feelings of euphoria and calmness. Unfortunately, it is very easy to become addicted to this feeling.

According to the American Psychiatric Association (APA), about 3-12% of people treated with opioids for chronic pain will develop an addiction. Additionally, 8.6 million Americans reported misusing prescription opioids in 2023.[1]

Taking opioids like hydrocodone is risky. While they can relieve pain signals and help you manage severe pain, it might be worth it to ask your doctor for a less addictive option that does not contain an opioid analgesic.

What Does the M366 Pill Look Like?

The M366 pill is white, oval-shaped, and comes as a tablet. It is about 15mm long and has “M366” printed on one side. It contains 7.5mg of hydrocodone and 325 mg of acetaminophen.

When used for managing pain, doctors typically advise their patients to take the M366 pill every 4 to 6 hours. That said, you should never take it more often, as you could end up consuming too much acetaminophen in 24 hours. Additionally, taking M366 pills more than every 4 to 6 hours could cause you to experience mind-altering effects from the hydrocodone.

What are the Active Ingredients in the M366 Pill?

The M366 pill contains both hydrocodone and acetaminophen. Understanding exactly how these substances work to manage chronic pain and severe pain will help you decide if the medicine is right for you.

Hydrocodone Bitartrate

The main ingredient in a M366 pill is hydrocodone bitartrate. These pills have 7.5mg of this substance. Hydrocodone is an opioid analgesic that binds to opioid receptors in your brain and spinal cord. Doing so blocks pain signals, allowing the medication to manage pain.

Even though hydrocodone is effective in reducing the severity of pain, there are risks to consider as well. Because hydrocodone can cause feelings of euphoria and relaxation, there is an increased risk of developing a physical dependence on the drug. Additionally, taking it long-term can cause you to develop tolerance and addiction.

It is also possible to experience respiratory depression if you take too much hydrocodone at once. Respiratory depression occurs when you suffer from an overdose. If you notice difficulty breathing, shallow breathing, or a blue tint to lips and fingernails, contact 911 immediately.

Acetaminophen

Acetaminophen (Paracetamol) is a non-opioid analgesic and an antipyretic agent. M366 pills contain 325 mg of this substance. It works in combination with hydrocodone to relieve severe pain and chronic pain.

While acetaminophen causes pain relief, it works differently from hydrocodone. Instead of affecting opioid receptors, it inhibits the production of prostaglandins, which are chemicals in the body responsible for inflammation and pain.

Acetaminophen affects the peripheral nervous system to induce pain relief and acts on the hypothalamus to reduce fever.

While acetaminophen is not addictive, you should still be careful about how much of it you are consuming. Exceeding the maximum daily dosage can lead to liver problems, as your body will not be able to process it fast enough.

Can Abusing Hydrocodone Bitartrate and Acetaminophen Lead to Addiction?

While acetaminophen won’t lead to addiction, hydrocodone will. In other words, if you are misusing M366 pills, you may eventually develop a substance use disorder. When M366 pills are used to reduce chronic pain, they are not meant to be taken long-term.

If you use M366 pills long-term or in a manner other than prescribed, you are at risk of developing a substance use disorder. The signs of opioid addiction may include:[2]

Using opioids more or for longer than intended
Having a hard time controlling how much opioids you use
Wanting to quit using opioids but being unsuccessful
Experiencing urges and cravings for opioids
Having a hard time meeting responsibilities at home, school, or work due to opioid use
Losing interest in previously enjoyed activities
Continuing to use opioids even though they are causing social problems and adverse physical or mental health effects
Getting into risky situations when you use opioids, such as driving under the influence
Needing to increase your dose of opioids to experience the desired effect
Experiencing withdrawal symptoms when you stop using opioids

If you are using hydrocodone for pain relief from severe pain, you have nothing to worry about. However, if you find that you are using M366 pills to get high, you will develop an addiction. That said, if you experience 2 or more of the above-mentioned symptoms of opioid addiction, you need to consider obtaining professional help.

What are the Other Risks of Abusing Hydrocodone?

Opioid addiction is not the only serious risk associated with abusing M366 pills. While these medications can reduce severe pain, they can also harm your health when used long-term. Being aware of the risks of hydrocodone might motivate you to seek help from an opioid addiction treatment center.

The serious risks associated with abusing hydrocodone pills include:

Allergic Reactions

Hydrocodone can trigger allergic reactions in some individuals. If you are allergic to this substance, you might experience:[3]

Itchiness and rashes
Hives
Red, swollen, blistered, or peeling skin
Wheezing and unusual hoarseness
Tightness in the chest or throat
Trouble breathing, swallowing, or talking
Swelling of the mouth, face, lips, tongue, or throat

If you experience any of these effects after taking an M366 pill, contact emergency medical services immediately. An allergic reaction to hydrocodone can lead to anaphylaxis, which is a life-threatening condition.

Adverse Side Effects

It is also possible to experience adverse side effects when abusing hydrocodone. Even if you don’t have an allergy, your body might not tolerate the medication. This could lead to unpleasant or hard-to-manage symptoms.

Hydrocodone works by affecting the opioid receptors in your brain. Some of the potential adverse side effects of hydrocodone include:

Drowsiness and dizziness
Nausea and vomiting
Constipation
Headaches
Stomach pain
Mood changes
Dry mouth
Itching
Weakness or lack of energy
Trouble sleeping

If you are taking hydrocodone for pain relief and experience these symptoms, you might need to ask your doctor about finding a replacement medication. There are other options for pain relief, some of them having fewer risks associated with them. For example, you could take ibuprofen and acetaminophen at the same time, which often causes the same level of pain relief as opioid medications.[4]

Withdrawal Symptoms

If you become addicted to the M366 pill, that means you have a physical dependence. In other words, your brain and body rely on the substance to function properly. If you suddenly stop using it, you will experience withdrawal symptoms.

Hydrocodone withdrawal can be intense and hard to cope with. They might include:[5]dose

Agitation and anxiety
Muscle aches and pains
Teary eyes and a runny nose
Insomnia
Excessive sweating
Increased yawning
Abdominal cramping
Diarrhea
Dilated pupils
Goosebumps and shivering
Nausea and vomiting

While M366 pill withdrawal is usually not life-threatening, you are likely to relapse without professional help. Relapsing on opioids after a period of abstinence can be dangerous, as you might attempt to take a large dose that your body was tolerant of before sobriety. As a result, you could experience a life-threatening opioid overdose and respiratory depression.

Neonatal Opioid Withdrawal Syndrome

If you find yourself abusing M366 pills while pregnant, you could be harming your unborn baby. For example, when pregnant women abuse opioids, their child could develop something called neonatal opioid withdrawal syndrome. This means your child will have opioid withdrawal when they are born.

The symptoms of neonatal opioid withdrawal syndrome include:[6]

Tremors (shaking)
Irritability (excessive crying)
Sleep problems
High-pitched crying
Tight muscle tone
Hyperactive reflexes
Seizures
Yawning, stuffy nose, and sneezing
Poor feeding
Vomiting
Diarrhea
Dehydration
Excessive sweating
Fever or unstable temperature
Rapid breathing

This condition could cause poor intrauterine growth, premature birth, seizures, and birth defects. If you are pregnant and struggling with opioid addiction, a professional rehab center could help you recover and prevent your baby from experiencing lasting effects.

Life-Threatening Respiratory Depression

If you take too much hydrocodone when abusing M366 pills, you could experience an opioid overdose. Opioid overdoses cause life-threatening and severe respiratory depression, which means you could have difficulty breathing.

The symptoms of an opioid overdose include:[7]

Blue or purple fingernails and lips (cyanosis)
Unresponsive to voice or touch
Pinpoint pupils
Slow, irregular, or stopped breathing (respiratory depression)
Slow heartbeat or low blood pressure
Pale, clammy skin
Choking or gurgling noises (“death rattle”)

As a central nervous system depressant, opioids like hydrocodone can quickly lead to life-threatening overdoses. When you take more than the maximum daily dosage, your central nervous system is slowed down to dangerous rates. The only way to overcome central nervous system depression is to receive emergency medical care.

Is There a Better Alternative to M366 Pills for Pain Relief?

If you want to avoid the potential risks and harmful drug interactions associated with opioids, there are other medications to consider. You’ll want to avoid other CNS depressants. While opioid pain medication is considered the strongest option, that might not be true.

For example, if you are taking M366 pills to cope with dental pain after a procedure, experts agree that there is a better option. You could combine over-the-counter drugs like ibuprofen and acetaminophen, which causes the same level of pain relief without putting you at risk of substance abuse, addiction, liver damage, severe allergic reactions, and adverse reactions, and overdoses.

If you have chronic pain from headaches, you could take certain antidepressants for pain relief. For example, Effexor, Cymbalta, and Savella can provide pain relief from headaches and migraines.

If you are using opioids to cope with nerve pain, you could take a medication like Gabapentin instead. While it is possible to abuse Gabapentin, the risks of addiction and overdose are much lower. Gabapentin works to alleviate pain by changing the way nerves send pain signals to the brain.

In other words, no matter what type of pain you are dealing with, you have other options than opioids to alleviate pain.

Can Addiction Treatment Help You Recover from Opiate Addiction?

If you abuse M366 pills, it’s time to seek professional help. Opioid addiction treatment centers can help you recover with a combination of services, including medical detox, medication-assisted treatment, evidence-based therapies, and relapse prevention planning. Knowing how these recovery tools work can motivate you to seek the help you need.

Medical Detox

If you suffer from opiate addiction, that means you’ll experience severe withdrawal symptoms when you stop consuming M366 pills. Thankfully, opiate addiction treatment centers offer medical detox services to help you overcome opioid withdrawal symptoms. You’ll be offered prescription medication that is approved by the FDA to manage opioid withdrawal, like Suboxone or methadone.

In addition to taking prescription medication to manage your symptoms, your health will be monitored consistently by a healthcare provider. They’ll take your vital signs regularly to ensure you are remaining stable throughout the withdrawal process.

Medication-Assisted Treatment (MAT)

MAT helps you overcome opioid addiction by managing withdrawal symptoms during detox and preventing cravings throughout the entire recovery process. By taking MAT medications, you lessen your chances of returning to substance abuse. That said, these medications should always be used in combination with behavioral therapy and relapse prevention planning.

According to the Substance Abuse and Mental Health Services Administration, MAT provides the following benefits for opioid addiction recovery:[8]

Improved patient survival
Increased retention in treatment
Decreased illicit opiate use and other criminal activity among people with substance use disorders
Increases patients’ ability to gain and maintain employment
Improved birth outcomes among women who have substance use disorders and are pregnant

Evidence-Based Therapies

If you suffer from opiate addiction, behavioral therapies are incredibly important to the recovery process. Once physical therapy, like medical detox, is completed, you’ll start working on the emotional and behavioral aspects of recovery.

During opiate addiction treatment, you’ll engage in individual therapy, group counseling, and family therapy. Science-based addiction treatment is used to ensure you receive the tools you need to achieve long-term recovery. Examples of evidence-based therapies include:

Cognitive behavioral therapy (CBT)
Motivational interviewing (MI)
Contingency management (CM)
12-step facilitation therapy
The matrix model
Family behavior therapy

When you first arrive at an opiate addiction treatment center, you’ll undergo an in-depth assessment. During this assessment, they’ll get your medical history, mental health details, and determine your goals for recovery. The information gathered during your assessment will be used to guide therapy, keeping your needs and goals in mind.

Relapse Prevention Planning

If you don’t prepare yourself to deal with triggers, you could experience a relapse and suffer from an overdose, which causes adverse reactions like shallow breathing and respiratory depression. Thankfully, opiate addiction treatment centers help you avoid this by offering relapse prevention planning.

During relapse prevention planning, you’ll learn about potential triggers and develop healthy coping mechanisms to overcome them. You’ll also develop a plan of action to use in case you experience a relapse in the future.

A major part of relapse prevention is aftercare. Aftercare programs often include the following services:

Continued therapy
Medical supervision for MAT medications
Access to an alumni support group
Referrals to outpatient and sober living programs
Recommendations on local support meetings, like 12-step programs
Case management services like vocational training and other life skills assistance

Does Insurance Cover Opiate Rehab?

If you began taking M366 pills in higher doses than prescribed, you probably developed an addiction. Long-term addiction to M366 pills can lead to a variety of dangers, including severe liver damage, worsened chronic pain conditions, and life-threatening overdoses. Thankfully, addiction treatment centers can help you recover.

When considering attending an opiate rehab, you might find yourself wondering if insurance covers it.
