What Are Ozempic & Mounjaro?
Ozempic and Mounjaro are both part of a drug class called GLP-1 receptor agonists. They act on hormones that help regulate appetite and insulin release after meals, which can improve blood sugar levels and help support weight management.
Ozempic contains semaglutide.
Mounjaro contains tirzepatide, which has a dual GLP-1 and GIP action, meaning it may impact more pathways in metabolism than older GLP-1 drugs.
These medications should always be taken under qualified medical supervision.
Why Some Things Should Never Be Mixed
Combining certain substances or behaviors with these drugs can:
Worsen nausea, vomiting, or diarrhea
Increase risk of dehydration or electrolyte disturbance
Impact nutrient absorption
Interact directly with how the drugs are metabolized
Reduce medication effectiveness
Some interactions are obvious (like alcohol), while others are more subtle (certain supplements or foods).
