What to Expect When Taking Naltrexone for the First Time

Starting any new medication can be daunting, but knowing what to expect can help ease your concerns and prepare you for the journey ahead.

Before Your First Dose

Before beginning Naltrexone treatment, it’s crucial to undergo a series of preparatory steps to ensure the medication is safe and effective for you.

  1. Medical Assessment: Your healthcare provider will conduct a thorough evaluation to determine if Naltrexone is the right choice for your treatment. This evaluation will include:
    • Physical Examination: A complete physical exam to check your overall health and identify any potential contraindications.
    • Blood Tests: Including liver function tests to ensure that your liver is healthy enough for Naltrexone use. Liver health is vital, as Naltrexone is metabolized by the liver.
    • Screening for Recent Alcohol or Opioid Use: Your healthcare provider will ensure that you have been abstinent from opioids for at least 7-10 days. If alcohol is involved, it's important to assess how long it's been since you last drank, though complete abstinence isn't always required before starting Naltrexone for alcohol dependence.
  2. Opioid-Free Period: If you're being treated for opioid use disorder (OUD), you will need to be opioid-free for at least 7-10 days before starting Naltrexone. This step is critical to avoid precipitated withdrawal, which can occur if opioids are still in your system. Withdrawal symptoms can be extremely uncomfortable, so following this recommendation is essential for a smoother transition into Naltrexone treatment.
  3. Medication Review: Inform your doctor about all medications, supplements, and herbal products you are taking. Naltrexone can interact with other medications, especially opioid-containing pain medications, leading to either reduced efficacy or adverse effects. Your healthcare provider will help you avoid potentially dangerous interactions by adjusting your medications if necessary.

Taking Your First Dose

When you’re ready to begin, your healthcare provider will guide you through the process of taking your first dose of Naltrexone. Understanding the dosage and the expected process can help reduce anxiety and improve your adherence to treatment.

  1. Dosage: The dosage and form of Naltrexone depend on individual circumstances:
    • Oral Naltrexone: The starting dose is typically 50 mg once daily. For those with concerns about tolerance or potential side effects, your doctor may start you at a lower dose and gradually increase it.
    • Extended-Release Injectable Naltrexone (Vivitrol): This is a 380 mg injection, given once a month by a healthcare professional. The injectable form is often preferred by individuals who struggle with adherence to daily medication or want a more consistent level of medication in their system.
  2. Timing:
    • Oral Naltrexone: Typically taken in the morning, either with or without food. However, if you experience side effects like nausea, your healthcare provider may recommend taking it with food or in the evening.
    • Injectable Naltrexone: Administered once a month in a clinical setting by a healthcare professional.
  3. Administration:
    • Oral Tablets: Swallow the tablet whole with a glass of water. Do not crush or chew the tablets.
    • Injectable Form: The injection is administered intramuscularly in the buttocks. It is essential to receive these injections from a trained healthcare professional to reduce the risk of complications, such as injection site reactions.

Immediate Effects

Understanding what Naltrexone does right after taking your first dose can help set realistic expectations.

  1. Opioid Blockade: Naltrexone immediately begins blocking opioid receptors in your brain. If you use opioids while on Naltrexone, you will not experience the typical euphoric effects. This can help reduce the desire to use opioids because the "reward" is no longer there.
  2. Alcohol Effects: For individuals being treated for alcohol use disorder, you may notice a reduction in cravings or desire to drink within hours to days of taking your first dose. This can make it easier to resist alcohol and begin breaking the habit.
  3. No "High" or Sedation: Unlike some addiction treatments such as methadone or buprenorphine, Naltrexone does not cause a euphoric "high" or sedation. You should feel mentally clear, which helps you stay engaged in therapy and everyday activities without feeling impaired.

Potential Initial Side Effects

It is common to experience some side effects as your body adjusts to Naltrexone. These side effects are generally mild and temporary:

  1. Nausea: This is the most commonly reported side effect, often diminishing after the first few days.
  2. Headache: Headaches may occur, especially early in treatment.
  3. Dizziness: Some individuals may feel light-headed or dizzy when they first start Naltrexone.
  4. Fatigue: Feeling tired is common as your body adjusts, but it usually improves over time.
  5. Anxiety or Nervousness: Some patients report feeling anxious or on edge initially.
  6. Sleep Disturbances: You may experience difficulties falling asleep or disrupted sleep patterns.

If these side effects are severe or do not improve after a few days to weeks, it's important to contact your healthcare provider for advice. They may adjust your dosage or provide additional strategies to manage these symptoms.


Common Experiences in the First Days and Weeks of Treatment

The first few weeks of Naltrexone treatment are a period of adjustment, and knowing what to expect can make this transition smoother.

Week 1

  1. Reduced Cravings: Many patients report a noticeable reduction in cravings for alcohol or opioids within the first week. This can make it easier to avoid substance use, especially during moments of high stress or temptation.
  2. Side Effect Management: Initial side effects, such as nausea or dizziness, may peak during this time but should gradually lessen. Managing these symptoms by staying hydrated, eating small and frequent meals, and getting enough rest can be helpful.
  3. Mood Changes: It’s not uncommon to experience mood swings or irritability, particularly as your body adjusts to being without alcohol or opioids. These changes can also be linked to emotional fluctuations that occur when you begin facing life without substances.
  4. Sleep Pattern Changes: Insomnia or disrupted sleep is also common in the early stages of treatment. Sleep patterns typically stabilize as the body gets used to Naltrexone.

Weeks 2-4

  1. Stabilizing Effects: By the second or third week, most individuals find that side effects have significantly diminished. This stabilization allows for greater comfort and a sense of normalcy.
  2. Continued Reduction in Cravings: The reduction in cravings becomes more noticeable, and many patients find that thoughts about alcohol or opioids decrease in frequency and intensity.
  3. Improved Clarity: As substance use ceases and Naltrexone helps manage cravings, you may experience greater mental clarity and focus. Many patients describe this as a feeling of being more "present."
  4. Emotional Processing: Without the numbing effects of alcohol or opioids, emotions may be more intense. This is a natural part of recovery, and therapy or counseling can be beneficial in helping process these emotions effectively.

Beyond the First Month

  1. Habit Changes: By the end of the first month, you may find it easier to avoid triggers and establish healthier routines. The medication's effects, combined with positive behavioral changes, make it easier to replace harmful habits with constructive ones.
  2. Relationship Improvements: As you gain control over your substance use, relationships with friends and family often improve. Without the influence of substances, you can reconnect more genuinely with loved ones.
  3. Physical Health Improvements: With continued abstinence, physical health benefits become evident, such as better sleep quality, more energy, and improvements in general well-being.
  4. Ongoing Adjustment: Recovery is an ongoing process. Continue working with your healthcare provider and participate in counseling or support groups to address new challenges as they arise.

Tips and Strategies for Following Your Prescribed Treatment Regimen

Adhering to your treatment plan is essential to achieving the full benefits of Naltrexone. Here are some effective strategies for staying on track:

Establish a Routine

  1. Set a Daily Reminder: Use your phone's alarm, a medication reminder app, or a pill organizer to ensure you take Naltrexone consistently every day.
  2. Link to a Daily Activity: Incorporate taking your medication into your existing routine, such as taking it with breakfast or after brushing your teeth.
  3. Plan for Weekends and Holidays: It’s easy to forget on weekends or holidays when routines change. Set specific reminders for these days to ensure you remain consistent.

Manage Side Effects

  1. Stay Hydrated: Drinking plenty of water can help alleviate common side effects like nausea or headaches.
  2. Eat Well: Eating a balanced diet, including fresh fruits and vegetables, can help minimize gastrointestinal side effects and provide the nutrients your body needs.
  3. Rest: Ensure that you get adequate sleep, especially if you experience fatigue as a side effect.
  4. Exercise: Regular physical activity helps boost mood, reduce anxiety, and manage fatigue. Even light activities such as walking or yoga can make a difference.

  2. Track Progress: Keeping a journal of your experiences can help you recognize patterns, identify triggers, and note improvements and challenges.
  3. Reward Yourself: Celebrate your achievements, no matter how small. Treat yourself to a favorite meal or take a relaxing day trip as a reward for reaching a milestone.
  4. Stay Connected: Maintain regular contact with your support system, including friends, family, and support groups. Social support is a crucial part of maintaining motivation.

Prepare for Challenges

  1. Identify Triggers: Work with a therapist to identify your triggers and develop strategies for managing them. These could include specific people, places, or situations that increase your risk of relapse.
  2. Emergency Plan: Have a plan in place for when cravings hit. This could include calling a trusted friend, practicing a coping skill, or using a distraction technique.
  3. Carry a Reminder: Keep a note, a photo, or another small item with you that reminds you why you are seeking recovery. This can provide motivation in moments of temptation.

Communicate with Your Healthcare Team

  1. Be Honest: Open communication with your healthcare provider is crucial. Share any concerns, side effects, or challenges you are facing.
  2. Ask Questions: There are no bad questions when it comes to your health. If you're uncertain about any aspect of your treatment, ask your provider for clarification.
