Mounjaro (tirzepatide), Wegovy (semaglutide), and Ozempic (semaglutide) have emerged as revolutionary treatments for weight management and type 2 diabetes. These injectable medications belong to the GLP-1 receptor agonist class, with Mounjaro also acting on GIP receptors, making it a dual agonist. While these medications can help with weight loss and blood sugar control, they are also associated with various side effects. Understanding these potential side effects and learning how to manage them effectively is crucial for a successful treatment experience.
This guide provides an in-depth review of the known side effects of Mounjaro, Wegovy, and Ozempic, along with expert advice on managing them.
Common Side Effects and How to Manage Them
Nausea
Why it Happens: GLP-1 receptor agonists slow gastric emptying, which can lead to nausea, especially when starting treatment or increasing the dose.
Management Tips:
Eat smaller, more frequent meals to prevent overeating.
Avoid greasy, spicy, or highly processed foods.
Stay hydrated with small sips of water or ginger tea.
Take the injection at bedtime to sleep through the worst of the nausea.
Gradually increase your dosage as prescribed to allow your body to adjust.
Vomiting
Why it Happens: A more severe response to slowed digestion and nausea.
Management Tips:
If vomiting is severe, speak to your healthcare provider about adjusting the dose or switching to a different medication.
Use anti-nausea remedies like peppermint tea or electrolyte solutions.
Avoid heavy meals, and eat bland, easy-to-digest foods like rice, bananas, and toast.
Diarrhea

Management Tips:
Stay hydrated with electrolyte-rich drinks.
