Ozempic, Wegovy, Mounjaro, Zepbound. You must have recognized at least one of these names in the past year.
And there has been plenty of chatter about them, some justified but much simply not true. If you’re researching them for yourself, here’s what you need to know.
The Hormone Behind Them
GLP-1 stands for glucagon-like peptide-1. After you eat, your gut naturally makes it. It instructs the pancreas to release insulin, reduces gastric emptying, and sends a signal to the brain that a person is full. GLP-1 medications mimic that hormone, but keep it active for much longer than the body is able to do by itself.
For many, that translates to less hunger, satiety comes sooner – food doesn’t take up so much headspace. And that last part surprises most people. That last part surprises a lot of people. The constant thinking about food, what to eat next, cravings that don’t go away, those tend to quiet down. It is the medication that changes how the brain is perceiving hunger.
Which Medication Is Which
Semaglutide is the active ingredient in Ozempic and Wegovy. Different approved uses and doses, same ingredient. Note: Ozempic is FDA approved for type 2 diabetes. Wegovy is used at a higher dose for weight management. Both are weekly injections.
Tirzepatide is at the Mounjaro and Zepbound Rather, it might not only affect one but two hormone receptors, GLP-1 and GIP, with clinical trial data showing an overall average weight loss slightly higher than semaglutide. Mounjaro approved for diabetes; Zepbound for weight. Also, weekly injections.
Liraglutide (brand name Victoza and Saxenda) is a long-standing, daily injection that’s still used but mostly been replaced by the weeklies for new patients.
Starting the Medication
Each of these begins with a small dose and then builds up. NOT because a medication needs time to build, but rather due to side effects. Entering slowly and low-key means nausea and other initial symptoms can be managed until your body gets used to it.
Nausea is the most common one, especially in the first few weeks and after each dose increase. Smaller meals help. Avoiding greasy or spicy food helps. Eating slowly helps. It usually eases after a few weeks at each level.
Constipation comes up a lot too. Fatigue early on. Most of it settles between dose increases and gets better as the body adjusts.
Semaglutide typically takes around 16 to 20 weeks to reach the standard maintenance dose. Tirzepatide is similar. People who push through the schedule faster to get to the full dose sooner usually deal with worse side effects.
Blood Sugar and Weight
For people with type 2 diabetes, controlling blood sugar is the main clinical reason for using these medications. Weight loss happens alongside it.
For people without diabetes using them for weight management, the weight loss is the goal but the metabolic effects are real and happen regardless.
What They Won’t Do
Weight tends to come back after stopping. That’s what the research shows consistently. For a lot of patients ongoing use is part of the plan rather than a short course.
Lifestyle still matters. These medications make eating less easier because hunger is lower, but what you eat and how you move still shapes results.
Not everyone is a candidate. Personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 are contraindications. History of pancreatitis is a consideration. A provider needs your full picture before prescribing.
Cost
Without insurance, branded GLP-1 medications run over $1,000 a month. Coverage depends heavily on the plan and the indication. Compounded semaglutide has been available at lower cost through some pharmacies but FDA guidance on compounded versions has shifted and availability isn’t consistent.
Talk to your provider about cost before you start. It’s a real part of the decision.
