<p>Tirzepatide is the active ingredient in 2 brand-name medications — Mounjaro and Zepbound. It’s also a newer class of drugs called GIP/GLP-1 receptor agonists. If you’re taking either and hope to lose weight, using the right dose matters. Here, we give you a 101 on tirzepatide dosage for <a href=https://www.helloklarity.com/service/weight-loss/ target="_blank">weight loss</a>, so you have the information you need.</p><div class="wp-block-klarity-cta-banner-section-v3 k-cmp k-section cmp-cta-banner-section cmp-layout--l-img cmp-background--sky-mist cmp-img-type--image cmp-img-mode--cover cmp-img-effect--none" style="--cmp-background-color:#e5f3fe" data-layout="l-img"><div class="k-section-inner"><div class="k-row"><div class="k-col"><figure class="k-img-wrapper"><img decoding="async" class="k-img" src="https://cms.helloklarity.com/wp-content/uploads/2024/06/How-do-Phenterminemedications-compare-to-other-weight-loss-medications.png" alt="A red-haired woman is sitting on a yoga mat and typing on her laptop, researching and comparing Phentermine to other weight loss medications" title=""></figure></div><div class="k-col"><h2 class="k-headline">Talk to a healthcare professional about a weight-loss medication</h2><div class="k-desc"><p>Online appointments in as little as 24 hours*</p></div><a class="k-cta k-cta--button" href=https://www.helloklarity.com/condition/weight-loss target="_blank">Find a provider</a></div></div></div></div><h2 class= "subtitle" id='heading_2_Available_forms_for_tirzepatide'>Available forms for tirzepatide</h2><p>Mounjaro and Zepbound are the only available forms of U.S. Food and Drug Administration (FDA)-approved tirzepatide. There’s no generic version of either medication. <a href=https://www.helloklarity.com/post/tirzepatide-compounding-pharmacy/ target="_blank">Compounded tirzepatide</a> is available. This is a custom medication that can be tailored to meet your needs or personal preference and is often cheaper than similar brand-name drugs.&nbsp;It’s important to talk to your provider about potential risks and benefits before trying compounded tirzepatide.</p><p>Tirzepatide is a combination GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) agonist. The dual action of the 2 leads to weight loss by mimicking the body’s natural GIP and GLP-1 hormones. They stimulate the pancreas to secrete insulin, which helps with blood sugar control. And they slow down how fast food leaves the stomach, which makes you feel full and decreases appetite so you can lose body weight.</p><p>Mounjaro was approved first in 2022 to help people with type 2 diabetes regulate their blood sugar, aka blood glucose. It’s intended to be used along with diet and exercise.</p><p>People taking Mounjaro found that they <a href=https://www.helloklarity.com/post/how-does-mounjaro-work-for-weight-loss/ target="_blank">lost weight</a>. And because Novo Nordisk’s <a href=https://www.helloklarity.com/post/ozempic-vs-wegovy/ target="_blank">Ozempic and Wegovy</a> were selling so fast they became <a href=https://www.helloklarity.com/post/where-can-i-find-wegovy-in-stock/ target="_blank">hard to find</a>, Mounjaro’s manufacturer Elli Lilly successfully got tirzepatide approved for weight loss as Zepbound in November 2023.</p><p>Zepbound was approved for use in obese adults or adults who are overweight and have 1 or more weight-related health problems like high blood pressure, type 2 diabetes, or high cholesterol. It should be used as part of a <a href=https://www.helloklarity.com/post/medical-weight-loss-programs/ target="_blank">weight loss program</a> that includes a reduced-calorie diet and increased physical activity.</p><p>Mounjaro is not approved for weight loss. And Zepbound is not approved to lower blood sugar for people with type 2 diabetes. But both help with weight loss. In 2 different clinical trials, people taking tirzepatide — with and without diabetes — <a href=https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=487cd7e7-434c-4925-99fa-aa80b1cc776b target="_blank" rel="noopener" target="_blank">lost 12.8 to 20.9% of their body weight</a> in 72 weeks.</p><h2 class= "subtitle" id='heading_2_Available_tirzepatide_dosages'>Available tirzepatide dosages</h2><p>Mounjaro and Zepbound are available in the same 6 dosages. Each dose comes in a&nbsp;prefilled single-dose pen. And one dose is&nbsp;taken each week.

You start out at a small dose, so your body can adjust and you can minimize common <a href=https://www.helloklarity.com/post/zepbound-side-effects/ target="_blank">Zepbound side effects</a>, like nausea, diarrhea, decreased appetite, vomiting, constipation, dyspepsia (pain in the upper stomach area), and abdominal pain. You then increase your dose every 4 weeks until you reach a maintenance dose.&nbsp;</p><p>For Zepbound, the target maintenance dose is often 15 milligrams. <a href=https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=487cd7e7-434c-4925-99fa-aa80b1cc776b target="_blank" rel="noopener" target="_blank">Clinical studies</a> show that people lose the most weight at this dosage. It’s possible for the maintenance dose of Zepbound to be lower — from 5 milligrams and up — depending on how well you tolerate it.</p><p>For Mounjaro the maintenance dose can be 5, 7.5, 10, 12.5, or 15 milligrams. The final maintenance dose depends on how much you need for ideal blood sugar control and how well you tolerate the medication.&nbsp;</p><h3 class="wp-block-heading">Tirzepatide dosage chart for Mounjaro vs Zepbound</h3><figure class="wp-block-table"><table><tbody><tr><td><strong>Weeks</strong></td><td><strong>Zepbound (tirzepatide) dosage</strong></td><td><strong>Mounjaro (tirzepatide) dosage</strong></td></tr><tr><td>Weeks 1–4</td><td>2.5 mg</td><td>2.5 mg</td></tr><tr><td>Weeks 5–8</td><td>5 mg 💉</td><td>5 mg&nbsp; 💉</td></tr><tr><td>Weeks 9–12</td><td>7.5 mg 💉</td><td>7.5 mg 💉</td></tr><tr><td>Weeks 13–16</td><td>10 mg 💉</td><td>10 mg 💉</td></tr><tr><td>Weeks 17–20</td><td>12.5 mg 💉</td><td>12.5 mg 💉</td></tr><tr><td>Weeks 21+</td><td>15 mg 💉</td><td>15 mg 💉</td></tr></tbody></table><figcaption class="wp-element-caption">💉 Potential maintenance dose.</figcaption></figure><p>If you don’t tolerate Zepbound or Mounjaro well, your healthcare provider may have you increase your dose more slowly, such as every 8 weeks.

One is to help treat type 2 diabetes, in which case your healthcare provider will likely prescribe Mounjaro. The other is to lose weight if you’re obese or overweight with a related health condition. In the latter case, your provider will prescribe Zepbound. If you have type 2 diabetes and have a body mass index of 27 or higher, which makes you medically overweight, your provider may also prescribe Zepbound.</p><p>When you take a medication with the active ingredient of tirzepatide for either reason, you can expect to lose some weight.
