Tirzepatide

GLP-1 / GIP, injection

Tirzepatide mimics the gut hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). When you eat, these hormones slow digestion and help you feel full. Tirzepatide also:

Reduces appetite

Balances blood sugar

Regulates insulin

What is
Tirzepatide
?

Tirzepatide is a drug that mimics the GLP-1 and GIP hormones. It’s sold under the brand names Mounjaro® and Zepbound^TM. The U.S. Food and Drug Administration (FDA) approved Mounjaro to treat type 2 diabetes. Clinicians have prescribed Mounjaro off-label for weight loss because clinical evidence shows it also helps people lose weight. Zepbound is FDA-approved for chronic weight management in adults who have obesity or excess weight (a body mass index of 27+ with at least one weight-related health condition).

Benefits of
Tirzepatide

Expected weight loss depends on the dosage. In a study funded by its manufacturer, Eli Lilly, participants taking 15 mg of tirzepatide lost an average of 48 pounds over 72 weeks, while those taking 5 mg of tirzepatide lost 34 pounds.

Tirzepatide also improves heart health by improving heart health metrics like blood pressure, blood sugar levels, and cholesterol, and helping people lose excess weight. Multiple clinical trials funded by Eli Lilly show tirzepatide can reduce the risk of heart attack, stroke, or death in adults with type 2 diabetes and those with excess weight or obesity.

It’s significant to note that some patients have reported reduced cravings and “food noise” and increased quality of life while using tirzepatide.

How does
Tirzepatide
work?

When you eat, the food stimulates your gut to release GLP-1 and GIP. When blood sugar levels are high after a meal, GLP-1 helps the pancreas release the right amount of insulin and slows how quickly the food moves through the digestive system. It also decreases glucagon, a hormone that controls the amount of glucose (blood sugar) the liver makes. GIP stimulates insulin release to help regulate low blood sugar levels after eating.

In some people, the gut doesn't make enough of these hormones on its own, or the brain isn't sensitive to them.

Tirzepatide is a combination of synthetic GIP and GLP-1, which act as a dual receptor agonist (RA). A drug that works as an agonist activates the same cell receptors as the body’s natural hormones. So, tirzepatide works in the gut like the body’s natural GLP-1 and GIP. Because tirzepatide slows digestion, it helps curb hunger and signal fullness to the brain. It also prompts insulin release, maintaining blood sugar levels after a meal. As a result, some people with obesity and overweight have lost weight while taking it.

Because tirzepatide supports processes the body isn’t doing well on its own, it may require long-term use.

It’s important to note that tirzepatide doesn’t work for everyone. There are many biological reasons why people struggle to lose weight. Found’s clinicians, trained in obesity medicine, can help patients identify the root cause of their weight gain and personalize a prescription to target it. All prescriptions are up to a medical provider’s discretion.

How to use it

Tirzepatide is typically taken once a week. Follow your care provider’s instructions for using tirzepatide. Eli Lilly recommends injecting Mounjaro or Zepbound under the skin in your upper arm, upper thigh, or stomach. Store the prefilled tirzepatide pens in the refrigerator.

Dosing

Dosing depends on your specific prescription and your care provider’s instructions. Please also read the pharmaceutical packaging.

Side effects

Rapid or significant weight loss can lead to too much muscle loss. To protect your muscles, it’s important to start a strength training program and exercise regularly while taking tirzepatide.

Tell your health care provider if you have severe stomach problems that won’t go away, including abdominal bloating or pain, acid reflux, a feeling of fullness after eating just a few bites of food, nausea, and vomiting, including vomiting undigested food eaten a few hours earlier. These may be symptoms of gastroparesis (stomach paralysis).

Use effective birth control while taking this medication. If you are pregnant, breastfeeding, or planning to become pregnant, do not take tirzepatide.

Tirzepatide is not appropriate for those with insulin-dependent diabetes or diabetic ketoacidosis. So, if that’s you, tirzepatide isn’t the right fit.

Black Box Warning

Although rare, tirzepatide caused thyroid C-cell tumors in animal studies. Both brand names of tirzepatide have a “black box” warning of the risk of these tumors. If you have trouble swallowing, develop hoarseness, or feel swelling or a lump in your neck, contact your health care provider immediately.

The FDA also warns not to take Zepbound or Mounjaro if you have a personal or family history of multiple endocrine neoplasia syndrome type 2 or medullary thyroid cancer.

Precautions

Rapid or significant weight loss can lead to too much muscle loss. To protect your muscles, it’s important to start a strength training program and exercise regularly while taking tirzepatide.

Use effective birth control while taking this medication. If you are pregnant, breastfeeding, or planning to become pregnant, do not take tirzepatide.

Tirzepatide is not appropriate for those with insulin-dependent diabetes or diabetic ketoacidosis. So, if that’s you, tirzepatide isn’t the right fit.

Interactions

Some drugs can also interact with tirzepatide, including:

Insulin
Sulfonylureas (when combined, these can cause blood sugar levels to drop dangerously low)
Some birth control pills
Other GLP-1 or GLP-1/GIP receptor agonist medications such as liraglutide, dulaglutide, or semaglutide

You should not drink alcohol while taking this drug because drinking can lower blood sugar. Combining alcohol with tirzepatide may cause blood sugar levels to fall too fast, leading to fainting and dizziness.

Alternative medications

Depending on your health history, weight history, and MetabolicPrint^TM assessment, your Found health care provider may consider other alternatives to help you lose weight. Some are FDA-approved for weight loss. Others are used off-label and have strong clinical evidence supporting their use for weight loss.

Unfortunately, there are no generic versions of Ozempic currently on the market.
However, your health care provider might consider alternatives such as Wegovy, Mounjaro, or Saxenda, all of which are GLP-1 medications but not all are FDA-approved for weight loss specifically.
