    •  Box Warning

      The official box warning for Mounjaro (tirzepatide) includes information about the risk of thyroid C-cell tumors. Specifically, it has been observed that in both male and female rats, tirzepatide causes dose-dependent and treatment-duration-dependent thyroid C-cell tumors at clinically relevant exposures. However, it is currently unknown whether Mounjaro causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans. The relevance of these findings from animal studies to humans has not been determined.

      Mounjaro is contraindicated for patients with a personal or family history of medullary thyroid carcinoma or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Patients are advised to be aware of the potential risk for MTC when using Mounjaro and to be informed about the symptoms of thyroid tumors, such as a mass in the neck, difficulty swallowing or breathing, and persistent hoarseness.

      It's important to note that routine monitoring of serum calcitonin or using thyroid ultrasound for early detection of MTC in patients treated with Mounjaro is of uncertain value and might lead to unnecessary procedures due to low specificity of these tests.

      Additionally, Mounjaro should not be used in patients with a history of pancreatitis, and care should be taken in patients receiving Mounjaro in combination with insulin secretagogues or insulin due to an increased risk of hypoglycemia

      What is Mounjaro?

      Mounjaro, or tirzepatide, is a prescription medicine patients with type 2 diabetes mellitus inject to improve their blood sugar. Though Mounjaro is not an official weight loss drug, when studied for weight loss over half of participants taking 10 mg or 15 mg lost 20% of their initial body weight or more. Your doctor will also instruct you to adjust your diet and exercise regularly to help you lose weight.

      The American Food and Drug Administration has not yet approved Mounjaro to be used as a weight-loss drug. It’s not commonly used in people with type 1 diabetes, and those with a history of pancreatitis should be cautious when considering Mounjaro.

      The FDA approved Mounjaro to be used to improve blood glucose levels in adults with type 2 diabetes when used together with diet and exercise in 2022. It may be approved by the FDA for treating overweight or  obese adults with weight-related health conditions.

      Mounjaro Cost & Coupons

      The climbing cost of Mounjaro can sometimes be covered by insurance. Nevertheless, some insurance plans will not cover it since it is a relatively new drug. It is common for insurance only to cover people with type 2 diabetes. People can contact their insurance provider to find out if their insurance covers Mounjaro.

      For Americans who have to buy Mounjaro without insurance, their medication can cost around $1,200 per month. This can be expensive, and many Americans seek a cheaper alternative to buy Mounjaro. One of these options is buying Mounjaro from Canada.

      How Do You Use Mounjaro?

      Prescription Mounjaro comes in an injectable “pen.” You use it once a week. It is injected under the skin of the stomach, thigh, or upper arm. You should change the place where you inject the drug each week, and don’t inject Mounjaro right next to insulin injections. You can administer it at any time of day and have food if you choose, but it is not required.

      Read all of the instructions, patient information, packets, and the prescription label carefully so you understand all of the information. Ask your doctor if you have any questions after reading. You shouldn’t take more or less of Mounjaro than your doctor has prescribed.

      If you need additional help, please do not hesitate to ask for a pharmacy consultation. These consultations are available for customers at Diet Pens. 

      Your physician will likely start you on a low dose that will be increased every four weeks until you reach the maximum or an effective dose.

      Mounjaro pens helps you control your type 2 diabetes, but it is not a cure. You may take Mounjaro for a month or longer before you see the medication’s full benefit. You should continue to take Mounjaro even if you feel well; don’t stop taking it without consulting your physician.

      How Does Mounjaro Work?

      This injectable medication helps the body release insulin when a patient’s blood sugar is high. It allows the body to remove excess sugar from the patient’s blood because it will enable the pancreas to make more insulin. It helps prevent the liver from making and releasing too much sugar. It helps patients eat less and slows down how quickly food leaves the stomach. Mounjaro pens also makes you feel full for a longer time. It does all this through activating hormone receptors GIP and GLP-1, two hormones that help your body regulate blood sugar.

      This medication is the first to tackle both GIP and GLP-1 receptors. Most of the trendy Type 2 diabetes medication or weight loss injection medications are GLP-1 agonists.

      Mounjaro Side Effects

      Patients who take Mounjaro for weight loss and diabetes report several common side effects. These include

      • Constipation
      • Diarrhea
      • Decreased Appetite
      • Indigestion
      • Stomach Pain
      • Vomiting

      Mounjaro patients may have more severe side effects. This medicine may cause thyroid tumors and thyroid cancer. Symptoms of these illnesses include a lump or swelling in your neck, trouble swallowing, hoarseness, or shortness of breath.

      In addition to this, Mounjaro may cause other serious side effects, which include:

      • Changes in your vision: You should tell your doctor promptly if you notice changes.
      • Pancreatitis: If you have significant stomach pain that will not go away, with or without vomiting, stop using Mounjaro and call your doctor immediately.

      Drug Interactions Of Mounjaro

      Before you start taking Mounjaro, you should talk to your doctor and inform them about every medication you are currently taking, including vitamins and supplements and other Diet Pens, such as Trulicity or Victoza. Mounjaro interacts with over 200 types of drugs, and two of those interactions are major. We’ll review the drugs and how to avoid these dangerous interactions.

      Interaction between Mounjaro and Bexarotene

      Bexarotene is a type of cancer medication known as a retinoid. Its brand name is Targretin. Taking both bexarotene and Mounjaro may make you more likely to get a pancreas disease called pancreatitis. To prevent this interaction, your doctor may prescribe an alternative medication, a smaller dose, or order more frequent monitoring to ensure safe use.

      Warning signs to look for include chronic nausea, vomiting, tenderness in the abdomen, and upper abdominal pain, especially if it wraps to your back or worsens after you eat. If you are taking both medications and have these symptoms, contact your physician immediately.

      Interaction between Mounjaro and Gatifloxacin

      Gatifloxacin is an ophthalmic medication used to treat eye infections. The medication is suspended in eye drops. Its brand name is Zymaxid. It can change how much glucose is in the blood, so people with diabetes shouldn’t take it. There have been reports of low and high blood sugar in patients taking both drugs. Those who were taking gatifloxacin and had severe cases of hypoglycemia have gone into comas and even died.

      Mounjaro Strengths & Dosages

      Most patients start with a dose of 2.5 mg once a week. After a month, the dose may be increased to 5 mg once a week.

      Your doctor may find that you require additional glycemic control. In that case, your dosage will be increased in 2.5 mg increments after at least one month on the same dose.

      The maximum dosage for Mounjaro is 15 mg once a week.

      Mounjaro can be administered at any time of day, with or without meals.

      When used as directed, each of these drugs can lead to significant amounts of lost weight. However, only Wegovy is approved by the FDA for chronic weight management at this time. 

      Zepbound is also approved for weight loss; same active ingredient as Mounjaro.

      Both of these prescription medications help control blood sugar levels in adults with type 2 diabetes when used alongside diet and exercise. Ozempic has also been approved to lower the risk of cardiovascular events like heart attack or stroke in people with type 2 diabetes.

      Mounjaro starts working right away to lower your blood glucose levels. It may take eight to 12 weeks to reach your A1C goal, and significant weight loss may occur within 28 weeks.
      If your doctor prescribes you Mounjaro, your blood sugar levels will likely improve quickly. This can temporarily make diabetic retinopathy symptoms worse, causing issues like blurry vision. Tell your doctor if you notice the following symptoms: a sudden loss of vision, spots in your field of vision, flashing lights, or blurred vision. You should also inform your doctor if you have a history of diabetic retinopathy.
      Mounjaro doesn’t cause fatigue, but fatigue is a common complaint of people with type 2 diabetes. If you have continuous or severe fatigue, tell your doctor.
      Pain from the injection is not a reported side effect of Mounjaro. However, because you inject Mounjaro under the skin, it is possible you may experience some pain or discomfort. Your prescribing doctor should teach you how to administer the injection to reduce the pain it may cause.

      As of late 2023, the FDA has yet to approve Mounjaro to be used for weight loss. However, clinical trials for using Mounjaro for weight loss have been promising. It is possible that the medicine will be approved for use for weight loss in the future. At the time, Mounjaro is only FDA-approved to reduce the blood glucose levels and A1C of adults with type 2 diabetes.

      If you are within four days after the missed dose, take it as soon as you remember. If more than four days have passed when you remember, skip the dose you missed and continue with your regular schedule. Never inject two doses of Mounjaro within three days of each other.

      Call Poison Control at 1-800-222-1222 if you believe you have taken too much Mounjaro or call for emergency medical assistance at 911.
