Description

What is Mounjaro 12.5mg Injection?

Overview

Mounjaro 12.5mg is a weight loss treatment available in a pre-filled pen for once-weekly injections. It is the UK-approved equivalent of the US-approved weight loss injection, Zepbound.

How It Works

The active ingredient, Tirzepatide, attaches to receptors for two key hormones, GIP and GLP-1, which your body naturally releases after eating. By mimicking these hormones, Tirzepatide encourages your pancreas to produce more insulin. This process helps regulate blood sugar levels and sends signals of fullness to your brain, reducing appetite and curbing cravings, which ultimately supports weight loss.

What is Mounjaro 12.5mg Injection?

Overview

Mounjaro 12.5mg is a weight loss treatment delivered via a pre-filled pen for once-weekly injections. It is the UK-licensed version of the US-approved weight loss injection, Zepbound.

Active Ingredient & How It Works

The key ingredient in Mounjaro is Tirzepatide, which targets two hormones—GIP and GLP-1—that are naturally released after eating. By binding to these receptors, Tirzepatide mimics the effects of these hormones, prompting your pancreas to release more insulin. This process helps regulate blood sugar levels while signaling your brain to feel full, thereby reducing appetite and preventing cravings, which ultimately aids in weight loss.

How does Mounjaro 12.5mg Injection Work?

Active Ingredient and Its Role

Mounjaro 12.5mg injection contains Tirzepatide, a GIP analogue that stimulates both GLP-1 and GIP receptors. These gut hormones are naturally released after meals and play a key role in regulating blood sugar levels.

Mechanism of Action

  • Hormonal Activation: Tirzepatide mimics the actions of GLP-1 and GIP, prompting the pancreas to release more insulin. This helps control blood sugar.
  • Appetite Control: Activation of these receptors also sends signals to the brain, increasing feelings of fullness and reducing appetite and cravings.
  • Slowed Stomach Emptying: It helps slow down the emptying of the stomach, contributing further to a reduced appetite.

When used alongside a reduced-calorie diet, regular injections of Mounjaro 12.5mg assist many patients in losing excess weight and managing their appetite effectively.

How do you use Mounjaro 12.5mg Injection?

Dosage and Administration

  • Always follow your doctor’s or pharmacist’s instructions exactly. If you are unsure, consult with your healthcare provider.
  • Each KwikPen contains 4 doses and is available in strengths of 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg, or 15mg.
  • Starting Dose: Begin with 2.5mg once weekly for the first 4 weeks.
  • Dose Increments: After 4 weeks, your doctor will increase your dose to 5mg once a week. Further increases by 2.5mg (up to 15mg) may be recommended, with each dose maintained for at least 4 weeks before any increase.
  • Everyone’s response varies, so there is no need to rush the dose escalation. You may remain on a lower dose for an extra month or even permanently if it suits you.
  • If side effects occur or if you do not tolerate a higher dose, you can reduce or maintain your current dose. Always consult our clinical team for advice.

Choosing Your Dosing Schedule

  • Use your KwikPen on the same day every week, with or without food.
  • Mark your chosen day on a calendar or note it in your “Instructions for Use.”
  • If needed, you can change your dosing day as long as at least 3 days have passed since your last injection. Continue with weekly dosing on the new day thereafter.

Injection Instructions

  • Preparation:
    • Familiarize yourself with the full guide provided with your pen.
    • Remove the pen from its packaging and check the expiration date.
    • Ensure you have a clean, dry injection site on your abdomen, thigh, or upper arm.
    • Remove the pen cap and clean the injection site with an alcohol swab.
  • Needle Attachment:
    • Select a new pen needle (always use a fresh needle for each injection).
    • Attach the needle securely by pushing it on straight and twisting until tight.
    • Remove the outer needle shield and set it aside.
  • Injection:
    • Hold the pen at a 90-degree angle against your skin.
    • Press the button on top to inject and hold the pen in place for at least 5 seconds.
    • Release the button to retract the needle.
  • Post-Injection:
    • Dispose of the used needle and pen according to your healthcare provider’s instructions.
    • Rotate injection sites each week to prevent skin irritation. If you also use insulin, use a different site for your insulin injections.

Additional Guidance

  • Mounjaro 12.5mg injection is taken weekly. Consistency is key—try to stick to the same time each week.
  • If you experience any side effects or have questions, consult your healthcare provider.

Who should not take Mounjaro 12.5mg Injection?

Contraindications

  • Do not use Mounjaro KwikPen if you are allergic to tirzepatide or any other ingredients in this medication. Refer to the product information leaflet for details.

Warnings and Precautions

  • Digestive Issues:
    Consult your doctor if you have severe digestive problems or delayed stomach emptying, including severe gastroparesis.
  • Pancreatitis:
    Do not use if you have ever experienced pancreatitis, which causes persistent severe stomach and back pain.
  • Eye Conditions:
    Avoid use if you suffer from eye problems such as diabetic retinopathy or macular edema.
  • Diabetes Medications:
    If you are taking a sulfonylurea or insulin, Mounjaro may lead to low blood sugar (hypoglycemia). Your doctor may need to adjust your dosage to reduce this risk.
  • Dehydration:
    When beginning treatment, you may experience vomiting, nausea, or diarrhea that can lead to dehydration. It is important to drink plenty of fluids and contact your doctor if you have concerns.

Age and Reproductive Considerations

  • Children and Adolescents:
    This medicine is not recommended for individuals under 18 years of age as it has not been studied in this group.
  • Pregnancy:
    Mounjaro should not be used during pregnancy because its effects on the unborn child are unknown. If you are pregnant, suspect pregnancy, or plan to conceive, consult your doctor. Contraception is advised while using Mounjaro.
  • Breastfeeding:
    The transfer of tirzepatide into breast milk is uncertain. If you are breastfeeding or planning to breastfeed, discuss with your doctor whether to postpone treatment or stop breastfeeding.

Driving and Operating Machinery

  • Although Mounjaro generally does not affect your ability to drive, combining it with a sulfonylurea or insulin might cause hypoglycemia. If you experience symptoms such as headache, drowsiness, weakness, dizziness, hunger, confusion, irritability, rapid heartbeat, or sweating, avoid driving or operating machinery and consult your doctor.

Additional Information

  • Sodium Content:
    Mounjaro KwikPen contains less than 1 mmol sodium (23 mg) per dose, making it essentially sodium-free.
  • Benzyl Alcohol:
    Each 0.6 ml dose contains 5.4 mg of benzyl alcohol [E1519], which may trigger allergic reactions. If you have liver or kidney disease, consult your doctor as high levels can lead to metabolic acidosis.

Does Mounjaro 12.5mg interact with any other medicines?

Tirzepatide and Stomach Emptying

Tirzepatide can slow the rate at which your stomach empties, which may affect how other oral medications are absorbed. This effect is most noticeable when you first begin treatment with tirzepatide.

Paracetamol

  • When taken with tirzepatide, the peak concentration (Cmax) of paracetamol decreases by 50%, and it takes an extra hour to reach its peak (tmax).
  • No adjustment to the paracetamol dose is necessary.
  • This effect on paracetamol absorption depends on the tirzepatide dose. Lower doses (0.5 and 1.5 mg) only slightly alter paracetamol levels, and after four weekly doses of tirzepatide (5/5/8/10 mg), paracetamol’s Cmax, tmax, and overall exposure (AUC) remain unchanged.

Oral Contraceptives

  • A single 5 mg dose of tirzepatide can lower both the peak concentration and overall exposure (AUC) of oral contraceptives, delaying their peak levels.
    • Ethinyl estradiol: Cmax is reduced by 59%, AUC by 20%, with a 4-hour delay in tmax.
    • Norelgestromin: Cmax is reduced by 55%, AUC by 23%, with a 4.5-hour delay in tmax.
    • Norgestimate: Cmax is reduced by 66%, AUC by 20%, with a 2.5-hour delay in tmax.
  • These changes are not deemed clinically significant for women with a normal BMI, so no dose adjustments are needed.

Special Considerations for Overweight or Obese Women

  • There is limited data on how tirzepatide affects oral contraceptives in overweight or obese women, so reduced effectiveness cannot be ruled out.
  • It is recommended that you switch to a non-oral contraceptive method or use a barrier method of contraception for 4 weeks when starting tirzepatide and for 4 weeks after each dose increase.
