Ozempic vs. Wegovy vs. Mounjaro:
Which is Right for You?

Confused by the new wave of weight loss injections? We break down the differences, risks, and how to track your weekly doses safely.

It seems like everyone is talking about GLP-1 agonists. But between Ozempic, Wegovy, Mounjaro, and Zepbound, it's easy to get lost.

These medications are powerful, but they come with complex dosing schedules (usually once a week) and potential interactions with your other daily pills. Managing them requires precision.

At a Glance: The "Big 4" Compared

Drug Name Active Ingredient FDA Approval Typical Dosing
Ozempic Semaglutide Type 2 Diabetes Weekly Injection
Wegovy Semaglutide Weight Loss Weekly Injection
Mounjaro Tirzepatide Type 2 Diabetes Weekly Injection
Zepbound Tirzepatide Weight Loss Weekly Injection

Semaglutide vs. Tirzepatide: What's the difference?

Semaglutide (Ozempic/Wegovy) mimics one hormone (GLP-1) to regulate appetite.
Tirzepatide (Mounjaro/Zepbound) mimics two hormones (GLP-1 and GIP), which recent studies suggest may lead to slightly greater weight loss results.

Pro Tip

Forget which day is "Injection Day"?

Weekly medications are the hardest to remember. DoseMed lets you set custom weekly cycles (e.g., "Every Tuesday") so you never miss a shot or double-dose by accident.

The Hidden Risk: Delayed Stomach Emptying

All these medications work by slowing down how fast your stomach empties (gastric emptying). While this helps you feel full, it can change how your body absorbs other medications.

If you take oral birth control, antibiotics, or heart medication, the delayed absorption might make them less effective or change their timing.

Safety Warning

Always run an interaction check when starting GLP-1 agonists. You can use the DoseMed AI Assistant to instantly check if your current pill list conflicts with Ozempic or Mounjaro.

Common Side Effects

  • Nausea: Very common when starting. Usually improves over time.
  • Fatigue: Your body is consuming fewer calories, which can lower energy levels.
  • "Ozempic Face": Rapid weight loss can lead to volume loss in the face. Hydration is key.
