Medication-assisted treatment (MAT) has transformed the landscape of addiction recovery. For patients battling substance use disorders, medications such as Suboxone (buprenorphine/naloxone), methadone, and naltrexone provide a lifeline. These medications reduce cravings, prevent relapse, and help patients lead functional lives.

But for all the hope MAT brings, recovery is rarely a clean slate. As many clinicians and patients have learned, the journey doesn’t end with freedom from substances. It often brings new challenges, especially in the form of medication side effects.

In recovery, the goal is not just survival. It also includes long-term mental, emotional, and cognitive health, making side effect management a delicate but necessary responsibility.

This article explores the “second diagnosis” that can emerge during recovery: the physical and psychological consequences of MAT itself.

Understanding MAT

Health authorities like the CDC and WHO widely endorse MAT because it reduces overdose risk and improves retention in treatment programs. For many, it bridges the gap between withdrawal and true recovery. 

Research published on ScienceDirect reveals that treatments like buprenorphine and methadone can cut opioid-related deaths by nearly 50%. 

Conditions like opioid use disorder (OUD) are alarmingly common in the U.S. Each year, an estimated 10 million Americans, about 3.8% of the adult population, struggle with opioid misuse, WebMD reports. In these situations, Medication-Assisted Treatment (MAT) isn’t just beneficial; it’s often a critical component of recovery.

However, as with any long-term medication regimen, MAT can trigger physiological shifts that may lead to side effects. These side effects can impact mental health, diminish quality of life, and even threaten a patient’s commitment to recovery if not managed carefully.

At that point, seemingly minor symptoms can carry significant psychological weight.

Common (and Often Overlooked) Side Effects of MAT

MAT plays a vital role in supporting recovery. However, it can cause side effects that are more common and more disruptive than many patients and providers initially realize.

1. Gastrointestinal Distress

Nausea, constipation, and bloating are frequent complaints, especially with opioid-based treatments like methadone or buprenorphine. Though often brushed off as minor, these symptoms can heighten anxiety and disrupt essential functions like sleep, nutrition, and emotional balance. 

According to Verywell Mind, substance use alters how neurotransmitters, chemical messengers in the brain, function. When substance use is suddenly stopped or replaced, the brain must readjust, often triggering both physical and mental withdrawal symptoms. This neurological upheaval can intensify gastrointestinal side effects, making them more distressing and harder to manage during recovery.

2. Dental Problems

One unexpected but serious side effect of MAT, particularly with medications like Suboxone, is significant dental damage. Suboxone is taken sublingually about three times a day, with each dose held in the mouth for around 10 minutes. Its highly acidic content, when exposed to teeth so frequently, can lead to tooth decay, gum disease, tooth breakage, and even tooth loss. 

Unlike other side effects caused by changes in brain chemistry or hormones, this issue stems directly from the medication’s delivery method. Unfortunately, this risk has often gone undisclosed to patients, as reported by TorHoerman Law. 

As a result, many people suffering from these dental problems have taken legal action against the manufacturer through the Suboxone lawsuit. They claim they were not properly warned about the potential for serious oral health damage.

3. Sexual Dysfunction

Particularly with methadone, decreased libido and erectile dysfunction are common. Methadone affects the brain’s HPG axis, which controls sex hormones like testosterone and prolactin. When testosterone drops and prolactin rises, desire and performance can take a hit. Both men and women may struggle with arousal or orgasm. 

Some studies show these effects are worse in people with chronic pain or long-term methadone use. Beyond the physical, these issues can lead to frustration, shame, and relationship tension, especially when someone is trying to reconnect emotionally after recovery.

4. Emotional Blunting or “Flat Affect”

Some patients on MAT report feeling emotionally muted or numb. This reduced emotional range can result from the medication’s pharmacological effects as well as post-acute withdrawal syndrome (PAWS). 

PAWS is a prolonged phase of withdrawal that affects mood and emotional regulation. Because of this, patients may experience feelings similar to depression. This overlap can make it harder for doctors to accurately assess and treat mental health conditions during recovery.

Psychiatric Consequences of Unmanaged Side Effects

Side effects are not just medical inconveniences, they’re emotional flashpoints. For a person in recovery, dealing with new health concerns can trigger:

• Feelings of failure or despair
  
• Social withdrawal
  
• Shame or embarrassment
  
• Distrust in healthcare providers
  

These experiences can undermine treatment adherence, leading patients to taper or stop MAT without clinical supervision. This can be a dangerous choice that significantly raises relapse risk.

FAQs

How can chronic side effects from MAT contribute to relapse risk?

Persistent side effects, whether physical or emotional, can decrease motivation to continue treatment, increase frustration, and contribute to feelings of hopelessness. This combination heightens relapse risk, making side effect management a critical component of comprehensive recovery care.

What challenges do patients face when balancing MAT side effects with daily responsibilities?

Patients on MAT often face challenges like fatigue, brain fog, and digestive issues that reduce focus and energy. These side effects can interfere with work, family, and social life. Flexible treatment plans and symptom support are essential to help patients manage daily responsibilities successfully.

How important is patient education about potential MAT side effects for treatment success?

Educating patients sets realistic expectations and eases anxiety about side effects. When patients understand their treatment, they are more likely to report issues early, adhere to medication, and stay engaged in recovery. This leads to better outcomes and stronger collaboration with healthcare providers.

Overall, Medication-Assisted Treatment is not a cure, it’s a cornerstone. Recovery is a long and complex process that involves physical healing, emotional recalibration, and reintegration into life. By recognizing and addressing the side effects of MAT, clinicians can offer care that truly supports the whole person.

The goal of addiction psychiatry should never be just abstinence. It should be sustainable well-being. This means acknowledging that the very tools we use to help patients recover can sometimes cause harm. It requires responding with empathy, transparency, and innovation.
