That said, just because you may qualify it doesn’t necessarily mean that your health insurance will cover the costs associated with it. We break down the Mounjaro cost and talk about how you maybe eligible to use a savings card to make it more affordable.

From if its in stock to where to buy online, let’s talk about buying Mounjaro.
Which Pharmacy has Mounjaro in Stock?

Obesity Treatment Questions
While this is a Mounjaro FAQ – there are often questions about other obesity treatments on the market compared to Mounjaro.
We covered the Mounjaro vs Wegovy here, but let’s answer other obesity treatment related questions.
Are Mounjaro and Ozempic the Same Thing?
While both are used to treat type-2 diabetes and off label as a weight loss treatment, no Mounjaro and Ozempic are not the same thing.
Mounjaro is a GIP and GLP-1 receptor agonist while Ozempic is a GLP-1 receptor agonist. Both drugs stimulate naturally occurring GLP-1 receptors, but Mounjaro goes a step further by also targeting GIP.
Is Mounjaro Better than Weight Loss Surgery?
Weight loss surgery, such as the gastric sleeve is an invasive treatment for losing weight. That isn’t necessarily a bad thing, but when asking if taking an injection is better than WLS, there are multiple things to consider and invasiveness is definitely one of them.
With gastric sleeve bariatric surgery, the average weight loss is 25% to 30 % of your body weight in the first one to two years. (source: Cleveland Clinic)
Weight loss on Mounjaro can vary per person (as can it with weight loss surgery.) According to clinical trials, participants treated with Mounjaro in studies lost between 5.5 kg (12 lbs) to 11 kg (25 lbs) on average according to drugs.com.
In order to maintain weight loss with gastric sleeve bariatric surgery, you will need to continue to watch what you eat – just as you would if you choose the Tirezepatide route.
Are Mounjaro and Wegovy the Same?
As mentioned above when talking about Ozempic, no Mounjaro and Wegovy are not the same. That said, Wegovy and Ozempic are the same. You may hear them referenced as semaglutide, which is the drug name. Wegovy and Ozempic are the brand names.
Wegovy brand name refers to the weight loss treatment from Novo Nordisk. Ozempic brand name refers to the type-2 diabetes treatment.
There is no clean cut answer as to if Wegovy or Mounjaro is better. This will vary on many factors.
Will Mounjaro for Weight Loss Be a Different Name?
There is speculation that like Novo Nordisk having two names for semaglutide, that Lilly will have an additional name for Tirezepatide for weight loss.
Mounjaro Insurance Questions
Here are answers to your health insurance covering Mounjaro questions.
What is a PA?
If your health insurance is requiring a PA, that means prior authorization. When an insurance company requires a PA, they will not pay for the treatment until it is authorized. The term PA may also be used for the term “pre-authorization.”
Typically your insurance company will require your doctor to fill out a form stating why you need a particular treatment. Insurance company will then review the prior authorization form to determine if you meet eligibility and that the treatment falls in line with your insurance plan.
Does Insurance Cover Mounjaro?
Insurance coverage for Mounjaro varies. Many companies will cover it, but only for type-2 diabetes. Other companies do not provide obesity treatment.
How Do I Know If My Insurance Will Pay For Mounjaro?
The questions all Mounjaro users want to know, does my insurance pay for it? To find out if you have Mounjaro insurance coverage, contact your PMB and ask if Tirezepatide/Mounjaro is on your insurance formulary. If it is, you will want to make to ask if there are any requirements for coverage.
A PBM is a pharmacy benefit manager. This is a third party company that works as the intermediaries between pharmacies and your health insurance provider.
There might be a designation that a certain diagnosis code is used or that you have a P.A. in order for it to be covered. The more information you know, the better when it comes to what your health insurance does and does not cover (and more so, what it requires to have something covered.)

Will Mounjaro Make You Tired?
While the jury is out on if fatigue and tiredness is a common Mounjaro side effect, we have heard many people do experience this. This often happens most after either an injection or when a Mounjaro dosage is changed.
Why Am I Cold After My Mounjaro Injection?
While this does not happen to everyone, this is often a common known side effect. Here is what Dr. Daniel Rosen gives 3 reasons on why you are cold.
If you have been on Mounjaro any amount of time and lost weight, you have lost subcutaneous fat. That fat keeps you warm. Now that it’s a thinner layer of subcutaneous fat, it’s like you threw off your coat and you are going to be colder.
Mounjaro works by tricking your body that there is a large amount of food in your intestines. Your body routes the blood towards your core, which makes your extremities feel colder.
In a state of weight loss, your body tries to conserve energy in places and it may not allocate as much energy and calories towards warming you up.

Available data with MOUNJARO use in pregnant women are insufficient to evaluate for a drug-related risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are risks to the mother and fetus associated with
poorly controlled diabetes in pregnancy (see Clinical Considerations). Based on animal reproduction studies, there may be risks to the fetus from exposure to tirzepatide during pregnancy. MOUNJARO should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
