What to expect the first week on Contrave?

5 min read

Contrave is a combination medication containing naltrexone and bupropion, approved for chronic weight management in adults. When beginning this treatment, understanding what to expect the first week on Contrave? is crucial for setting realistic expectations and successfully managing potential initial side effects.

Quick Summary

The first week on Contrave involves a low starting dose to help your body acclimate to the medication. Common initial side effects include nausea, headache, and constipation, which often subside. Appetite changes may begin, though significant weight loss is not expected so soon.

Key Points

  • Gradual Dosage Escalation: Contrave is typically started at a low dose, which is gradually increased according to a schedule provided by your healthcare provider, to help your body adjust.

  • Expect Initial Side Effects: Mild to moderate side effects like nausea, headache, and constipation are common during the first week, but they typically improve over time.

  • Minimal Weight Loss: Do not expect significant weight loss in the first week. The initial period is focused on managing side effects and acclimating to the treatment.

  • Manage Side Effects with Simple Strategies: Combat nausea by eating bland foods, stay hydrated to ease headaches and constipation, and take your dose as prescribed to minimize trouble sleeping.

  • Prioritize Safety: Be aware of serious but rare risks, including seizures and mood changes, and contact your doctor immediately if any severe symptoms occur.

  • Combine with Healthy Habits: Contrave is most effective when used alongside a reduced-calorie diet and increased physical activity, not as a standalone solution.

What Is Contrave?

Contrave is a prescription weight-loss medication for adults living with obesity (BMI ≥30) or those who are overweight (BMI ≥27) with at least one weight-related condition, such as type 2 diabetes or high blood pressure. It is a combination of two established medications: naltrexone and bupropion.

  • Naltrexone: This component is an opioid antagonist typically used for alcohol or opioid dependence. In Contrave, it works to help control food cravings.
  • Bupropion: This is an antidepressant that increases dopamine and norepinephrine levels in the brain, which can help regulate appetite and reduce the reward-center response to certain foods.

The combined effect of these two ingredients targets areas in the brain that control hunger and reward, helping to manage cravings and reduce overall food consumption.

The First-Week Dosage Schedule

The first week on Contrave is part of a gradual dose-escalation schedule designed to minimize potential side effects and help your body adjust to the medication. It is vital to follow your doctor's instructions precisely and not increase the dose faster than recommended.

Contrave is typically started at a low dose and gradually increased over several weeks. This approach helps the body adjust to the medication and can minimize the severity of potential side effects. Your healthcare provider will provide a specific schedule for increasing the dosage.

Tablets should always be swallowed whole and never cut, chewed, or crushed. Taking more than prescribed can increase the risk of serious side effects, such as seizures.

Common Side Effects in the First Week

Many people experience mild to moderate side effects during the first four weeks, with symptoms often being most pronounced initially. As your body adjusts, these issues frequently lessen or disappear entirely. The most common side effects during this period are often gastrointestinal or neurological in nature.

  • Nausea: This is the most frequently reported side effect and is experienced by approximately one-third of clinical trial participants. It often subsides over time.
  • Headache: Headaches are also common as the body adapts to the medication.
  • Constipation: Altered bowel habits are a known effect, reported by many users.
  • Dizziness: Some individuals may feel lightheaded or dizzy, especially when first starting.
  • Dry Mouth: This can be a bothersome but manageable side effect.
  • Insomnia (Trouble Sleeping): The bupropion component can affect sleep patterns, particularly if the evening dose is taken too late.

Strategies to Manage First-Week Side Effects

Though initial side effects can be uncomfortable, several strategies can help make the first week more manageable.

  • Combat Nausea: Try taking your tablet with a small amount of bland food, like dry toast or saltine crackers. Avoid taking it with a high-fat meal, as this can increase medication absorption and side effects.
  • Address Constipation: Increase your fiber intake with more fruits, vegetables, and whole grains, and ensure you are drinking plenty of water.
  • Ease Headaches: Staying well-hydrated and using over-the-counter pain relievers, like acetaminophen, can help. Always check with your doctor before taking new medication.
  • Handle Dizziness: To prevent falls, move slowly, especially when getting up. Remaining well-hydrated can also help.
  • Manage Dry Mouth: Sip water throughout the day or chew sugar-free gum to increase saliva production.
  • Improve Sleep: If insomnia is an issue, ensure you follow a strict dosing schedule and take your evening dose earlier, as advised by your doctor.

Appetite and Cravings Changes

During the first week, it is normal to experience subtle changes in appetite and cravings, but it is unlikely you will see dramatic results. Contrave works gradually, with more significant effects typically seen after 4 to 12 weeks of consistent use. The first week is about starting the process, not achieving immediate weight loss. You may feel more full after meals or notice fewer urges to snack, which are early signs the medication is working. However, this is not a substitute for a balanced diet and regular exercise, which are essential partners to Contrave for long-term success.

What to Expect vs. Reality: A First-Week Comparison

For new users, the initial days can involve a lot of uncertainty. Here is a comparison of common expectations versus the typical reality of the first week on Contrave.

Aspect Common Expectation First-Week Reality on Contrave
Weight Loss Immediate and noticeable drop in weight. Often little to no weight change. Weight loss is a gradual process, with initial weeks focused on body adjustment.
Side Effects Few to no side effects. Mild to moderate side effects like nausea, headache, and constipation are common.
Appetite Drastic, immediate reduction in hunger. Subtle shifts in appetite and fewer intense cravings begin to emerge.
Energy Levels Significant increase in energy. Can cause some fatigue or trouble sleeping (insomnia) initially, which may affect energy levels.
Lifestyle Changes Medication handles everything. Medication aids cravings, but success still requires a reduced-calorie diet and increased physical activity.

Important Safety Considerations

While most first-week side effects are manageable, some serious risks are associated with Contrave. It is crucial to be aware of these and contact your healthcare provider immediately if you experience any concerning symptoms.

  • Seizures: The bupropion component can increase seizure risk. This is a risk for anyone, but especially if you have a history of seizures or certain medical conditions.
  • Increased Blood Pressure and Heart Rate: Blood pressure and heart rate can increase, especially in the first three months. Your doctor will likely monitor these regularly.
  • Mood Changes and Suicidal Thoughts: Bupropion carries a boxed warning for suicidal thoughts and behaviors. Pay attention to any sudden or unusual changes in mood or behavior.
  • Liver Problems: Rare but serious liver damage can occur. Seek immediate medical help for symptoms like dark urine, yellowing of the skin/eyes, or persistent abdominal pain.

Conclusion

For those beginning their journey, the first week on Contrave is primarily a period of adjustment. You may experience some common side effects, but these are often mild and temporary as your body acclimates to the medication. Focus on establishing a routine, managing potential symptoms with simple strategies, and supporting your treatment with a healthy diet and increased physical activity. Remember that significant weight loss is a marathon, not a sprint, and Contrave is a tool to help you control cravings and manage your appetite. The most important step during the first week is to stay in close communication with your healthcare provider to ensure a safe and effective start to your weight management plan.
