How Long Mounjaro Stays In Your System & Mounjaro’s Half-Life

Mounjaro (tirzepatide) is a prescription medication used to help treat type 2 diabetes. 

If you’re planning on stopping Mounjaro, you might wonder how long it will stay in your system.

Keep reading to find out the half-life of Mounjaro and how to flush the drug out of your body faster.

How Long Does Mounjaro Stay In Your Body?

Mounjaro is a long-acting medication, so it stays in your system for quite some time. It typically takes around 25 to 30 days for Mounjaro to stay in your body. 

Keep in mind that this might vary from person to person. How long it stays in your system relies on genetics, metabolism, and other factors. 

These factors can increase or decrease the duration of the medication in your system. 

What Is The Half-Life of Mounjaro?

A medication’s half-life is how long it takes for half of its dosage to be cleared from your system. The half-life of Mounjaro is quite long since it takes almost 5 days for the dosage to be reduced by half. 

As mentioned, keep in mind that there are some factors that might affect the metabolization of Mounjaro and its half-life, such as liver problems, metabolic issues, or genetics.

Now, since the effect of Mounjaro is fading away, if you don’t make any lifestyle changes, know that your glucose levels might become affected. 

How To Flush Mounjaro Out of Your System Fast

There is no way to “flush” the medication. You simply need to let it take its course for it to get out of your system. 

However, there are some things that can make it easier for the body to metabolize the medication and get it out of your system. 

Here are some things that can promote proper liver function.

Eat a healthy diet

A healthy diet not only is going to help promote good blood glucose levels, but it can also ensure proper liver function. 

Include nutrient-rich foods, and eat a diet with as many fresh ingredients as possible. Avoid saturated fats and trans fats (such as fast foods and pastries). 

Stay hydrated

Drinking plenty of water can help the body flush everything from your system. Drink at least half your body weight (pounds) in ounces of water. 

For example, if you weigh 180 lbs, you should strive for 90 ounces of water. 

Avoid alcohol consumption

The liver is the one responsible for metabolizing alcohol. And, since it’s a highly harmful molecule for your body, it stops every process until it gets rid of it. 

So, if you drink alcohol, the liver might have a hard time clearing up Mounjaro from your system. 

Avoid taking excess medications or supplements

Just like with alcohol, anything that needs processing needs to go through the liver. So, the more molecules the body needs to process, the more challenging it can be to remove Mounjaro. 

Include fatty fish

Fatty fish (salmon, mackerel, and sardines) are high in omega-3 fatty acids, which studies show can help reduce inflammation. 

If you are not too fond of fatty fish, you can include some plant-based sources in your diet, such as hemp seeds, chia seeds, and flax seeds. 


Mounjaro is an anti-diabetic medication intended to help blood sugar levels in people with type 2 diabetes. 

It comes in a pre-filled pen, which you inject once a week. If you are thinking about coming off the medication, first make sure you talk with your doctor. 

And know that Mounjaro has a long half-life (5 days), meaning it might take up to 25 to 30 days to get out of your system completely. 

Remember to keep up your healthy lifestyle habits. Otherwise, it can result in your blood glucose levels increasing again.
