Dextromethorphan (DXM) Withdrawal: Symptoms, Timeline, and Treatment

Dextromethorphan (DXM) is a dissociative anesthetic and a widely used synthetic compound in over-the-counter cough and cold medications. DXM has a long-standing record of effectiveness and safety in alleviating coughs when taken in therapeutic amounts and at a recommended dosage. When used correctly, DXM offers short-term relief from sinus congestion, coughing, a runny nose, nasal and throat itchiness, and watery eyes.

However, in large quantities, dextromethorphan may produce strong psychedelic effects and is often abused for recreational purposes. These effects are frequently likened to those produced by substances such as PCP or ketamine [1]. Misusing dextromethorphan along with other substances or alcohol can lead to severe side effects, health issues, or even death.

Dextromethorphan is available in tablets, gel caps, and liquid form. Traditionally, the inappropriate use of DXM was associated with its liquid form, but nowadays, individuals may misuse all three forms for recreational reasons. While not everyone who misuses DXM will develop an addiction, regular misuse can lead to addiction and may result in dependence and withdrawal symptoms.

DXM Abuse and Addiction

The recommended dosage of DXM is 10 to 20 mg every four to six hours or 30 mg every six to eight hours. The quantity required for achieving the ‘high’ varies between 250 and 1500 mg. These large amounts of DXM produce psychoactive effects, causing euphoria and dysphoria, visual and auditory hallucinations, impaired motor skills, dissociative sedation, nausea, and vomiting [2].

During these robotripping experiences, individuals may also have the following symptoms:

  • Panic attacks
  • Excessive sweating
  • Sedation
  • Slurred speech
  • Racing heart rate

What Causes DXM Withdrawal?

Dependence or addiction to DXM eventually results in withdrawal. When an individual takes significant amounts of DXM over an extended period, their brain and body adapt to the substance, becoming dependent on it for everyday functioning.

Consequently, when these individuals cease its use or lower the dosage, they undergo a range of distressing physical and psychological symptoms referred to as Dextromethorphan withdrawal. These symptoms occur because the brain and body have difficulty readjusting to normal functioning without DXM.

Symptoms of DXM Withdrawal

The symptoms of dextromethorphan withdrawal can vary substantially in intensity and duration depending on gender, genetics, weight, body chemistry, severity of addiction, and presence of co-occurring mental health or substance use disorders.

Common physical symptoms of DXM withdrawal include:

  • Fatigue
  • Headaches
  • Stomachaches
  • Sweating
  • Lack of energy
  • Feeling demotivated
  • Muscle aches
  • Severe impact on lung capacity
  • Nausea
  • Vomiting
  • Dehydration
  • Heatstroke

Common psychological symptoms of DXM withdrawal include:

  • Anxiety
  • Nervousness
  • Restlessness
  • Cravings to use DXM again
  • Depression
  • Insomnia
  • Feeling sad or hopeless
  • Mood swings
  • Emotional instability

DXM Withdrawal Timeline

Like withdrawal symptoms, the duration of DXM withdrawal is also different for every individual. Certain crucial factors that govern the length of DXM withdrawal include overall physical and mental health, the dosage and frequency of use, and additional substance abuse.

Here is a general overview of the DXM withdrawal timeline:

Day One to Two

Typically, signs and symptoms of DXM withdrawal initially manifest within 24 to 48 hours. However, these symptoms are fewer in quantity and not very intense.

Day Two to One Week

In the initial week of DXM withdrawal, new symptoms might arise while existing symptoms typically intensify in severity. This phase marks the onset of what is referred to as ‘acute’ withdrawal.

Two Weeks to Three Weeks

In the second week of DXM withdrawal, symptoms usually decrease in intensity, and most will completely fade away by the end of the week. This is the final stage of acute withdrawal.

Three Weeks to Two Years

In some cases, certain symptoms of DXM withdrawal, particularly psychological ones, might last for as long as two years. These are referred to as ‘post-acute’ withdrawal symptoms.

Detox and Treatment for DXM Withdrawal

Managing dextromethorphan withdrawal symptoms independently without professional medical help can be challenging, and the resulting discomfort can significantly hinder the ability to quit. Personalized medical detox programs can simplify the management of DXM detox and withdrawal, as well as enhance the chances of maintaining long-term sobriety [3].

Moreover, medical detox offers continuous oversight and pharmaceutical support to alleviate the intensity of withdrawal symptoms. Therapeutic interventions are also offered to assist in tackling the psychological effects of withdrawal and prepare for admission into rehab. A drug rehab program is an extremely effective method to tackle the factors leading to addictive behavior. It can also offer essential life skills, education, and behavioral therapy to control addictive tendencies and facilitate a sober lifestyle.

To maximize the chances of navigating through DXM withdrawal and preventing relapse, remember these tips:

Don’t Go Cold Turkey

Withdrawal symptoms from DXM are typically the most intense and toughest to endure when an individual abruptly quits “cold turkey,” meaning they cease taking DXM suddenly and without undergoing detoxification.

Stopping abruptly results in a much more distressing experience for the individual and greatly heightens their chances of returning to the habit. Hence, the most advisable approach is to gradually taper your usage, preferably with the assistance of healthcare professionals.

Medically Supervised Detox

As highlighted above, medically supervised detox provides continuous individualized monitoring and assistance from healthcare professionals. Possible medical interventions for DXM withdrawal may include:

  • Tapering
    • The DXM dose slowly decreases over a period, allowing the body additional time to adjust to its removal.
  • Medications
    • Occasionally, over-the-counter drugs are utilized to lessen or completely remove the symptoms of DXM withdrawal.
  • Oversight
    • Healthcare providers oversee and check on patients receiving DXM detox to ensure they are secure, at ease, and dedicated to the procedure.

Therapy and Counseling

Therapy and counseling are also routinely used for DXM withdrawal management. The following are among the most effective and common therapies:

  • Cognitive behavioral therapy (CBT)
    • CBT helps individuals recognize negative behavior and thought patterns. It also aids in modifying these patterns and developing healthy coping strategies to resist potential triggers.
  • Dialectical behavior therapy (DBT)
    • DBT coupled with CBT and other mindfulness strategies, are significantly useful for handling DXM withdrawal in patients with co-occurring mental problems and emotional issues.
  • Mindfulness-based stress reduction (MBSR)
    • MBSR encourages an unbiased and general understanding of feelings and thoughts. It combines meditation, mindfulness, and other self-awareness techniques to help mitigate stress and deal with cravings.
  • Motivational interviewing (MI)
    • MI boosts motivation for change and reduces uncertainty about withdrawal and rehab.
  • Contingency management (CM)
    • CM offers practical incentives and rewards to encourage and reinforce positive behaviors.

Self-Help Strategies

Here are certain useful self-help strategies to facilitate individuals through DXM withdrawal:

  • Health
    • Keep yourself hydrated and maintain a balanced, nutritious eating plan that includes drinking ample water and consuming fruits, vegetables, whole grains, and lean proteins. Add vitamins B and C to the diet. Steer clear of processed, sugary foods that could worsen symptoms.
  • Sleep
    • The body and mind require time to recover during withdrawal. Ensure adequate sleep every night and rest during the day when necessary. Don’t overexert; have a companion to keep an eye on symptoms and overall health.
  • Self-Care
    • Enjoy warm, soothing baths or showers. These may assist in alleviating agitation, anxiety, physical pain, and nausea. Electrolyte replacement beverages can also aid in alleviating nausea.
  • Exercise
    • Mild workouts like stepping outside to find distraction and uplifting fresh air, or exploring alternative exercises to channel restlessness can be extremely helpful.
  • Social Life
    • Maintain connections with encouraging friends, family, medical professionals, or recovery support groups. Reach out to cherished ones during the hardest time with loneliness and urges.

Supporting a Loved One in DXM Withdrawal

There are several effective methods to assist a loved one during DXM withdrawal. First and foremost, acknowledge the difficulties of DXM withdrawal and educate yourself about the withdrawal process and its physical and mental impacts. This will allow you to better support your loved one with compassion and understanding.

Another crucial aspect is ensuring effective communication and emotional backing to establish a secure, accepting environment that fosters open dialogue. Engage in active listening and provide emotional assistance whenever you can.

Next, avoid being an enabler. Even individuals with good intentions may unintentionally promote harmful behaviors in those struggling with substance use issues. Establish limits, avoid using items containing DXM, and think about individual or family therapy.

For more effective recovery, promote professional assistance. Any professional support, whether it’s detox, rehabilitation, or therapy, will significantly boost the chances of your loved one attaining and upholding sobriety.

Lastly, help them avoid relapse by learning to recognize triggers, create coping techniques, and implement healthy lifestyle adjustments. Most importantly, always acknowledge every achievement.

Long-Term Recovery and Relapse Prevention

Sustained recovery from DXM is achievable only if individuals can effectively avoid relapse. Fortunately, numerous strategies and tools for preventing DXM relapse are available [4].

Create a Relapse Prevention Plan

A relapse prevention plan functions as a guidebook to assist you in comprehending and predicting triggers more effectively and providing you with the necessary actions and resources to manage them. You can develop a relapse prevention plan with your addiction treatment team or personal therapist, and you can also make one by yourself. Moreover, you must regularly review and update the plan.

The prevention plan should include all your triggers, effective coping methods to soothe your feelings and divert attention from cravings, a contingency plan for managing high-risk scenarios, and a list of friends, family members, professionals, and support groups.

Seek Ongoing Support and Therapy

It is important to pursue continuous support and therapy to avoid relapse. Various forms of therapy are available for preventing DXM relapse, such as individual counseling and family therapy. Moreover, group therapy or support groups can be particularly beneficial, offering a continuous source of assistance, guidance, and community.

Develop Healthy Coping Strategies

Experimenting with various activities while keeping an open mindset to evolve into the individual you genuinely aspire to be takes time and perseverance. However, it yields great rewards ultimately.

These include:

  • Engaging in mindfulness and meditation
  • Participating in consistent physical activity
  • Expressing yourself through art and music
  • Reading
  • Spending time with family and friends
  • Engaging in outdoor activities
  • Becoming part of a club based on hobbies or interests
  • Ensuring adequate sleep and nutritious food
  • Pursuing further education
