There is no known drug interaction between Prevacid (lansoprazole) and Contrave (bupropion; naltrexone). They are considered safe to take together. However, it is important to follow the proper administration instructions for each drug for maximum effectiveness.


Prevacid: Administer on an empty stomach, 30—60 minutes before meals. If given once daily, administer before the first meal of the day.


Contrave: Administer by mouth in the morning and in the evening. May be administered with or without food; avoid administering with high-fat meals due to significant increases in bupropion and naltrexone systemic exposure.

About Prevacid (Lansoprazole)

Prevacid (lansoprazole) is an acid proton-pump inhibitor (PPI). It is used for the short-term treatment of a variety of conditions including, duodenal or gastric ulcers, gastroesophageal reflux disease (GERD), and erosive esophagitis. PPIs should be administered 30 to 60 minutes before a meal for maximal pH control. While Prevacid will begin to work within 1-2 hours after taking a dose by mouth, it can sometimes take a few days for optimal effects.

About Contrave

Contrave is a combination medication, containing bupropion (an antidepressant) and naltrexone (an opioid antagonist). It is indicated as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in obese adults (BMI: > = 30 kg/m2) or in overweight adults (BMI: > = 27 kg/m2) with at least one weight-related comorbidity (e.g., hypertension, type 2 diabetes mellitus, or dyslipidemia). Contrave works by affecting areas of the brain involved in the regulation of food intake and appetite.
