Where to Inject Mounjaro for Best Results?

The good news is that the location of your Mounjaro injection isn’t directly responsible for impacting its effectiveness for weight loss. However, choosing the right injection site can optimize your experience in terms of comfort and consistency. Here’s some guidance:

Recommended Injection Sites:

  • Abdomen: Ideal for its thicker fat layer, ensuring smooth absorption. Aim for either side, at least 2 inches away from the belly button. Avoid areas with veins or scars.
  • Upper Arms: Provides good muscle density and absorption. Choose the back of the upper arm, pinching a skin fold if needed.
  • Thighs: Another area with good fat and muscle. Focus on the outer upper thigh, avoiding veins and scar tissue.


  • Rotate injection sites: Don’t inject in the same spot each time to prevent skin irritation and scarring.
  • Cleanse the area: Use alcohol wipes to disinfect the chosen site before injecting.
  • Inject at 90 degrees: Hold the pen straight and perpendicular to the skin.
  • Press and hold: After injecting, press the injection site for a few seconds to prevent bleeding.

Additional Tips:

  • If you’re new to injections, consider watching instructional videos or asking your healthcare provider for a demonstration.
  • If you experience discomfort, redness, or swelling at the injection site, consult your doctor.
  • Be sure to store your Mounjaro at the recommended temperature and dispose of used pens safely.

While the precise location isn’t key to effectiveness, following these guidelines and adhering to your doctor’s instructions can ensure a comfortable and consistent injection experience with Mounjaro.

How frequently should I switch injection sites?

Generally, try to switch injection sites after each dose (every 7 days). This minimizes the chance of overusing any one area and keeps things fresh. If you find a particular location especially comfortable, you can stretch it to every other dose (every 14 days), but aim not to go longer than that.

How long does mounjaro stay in your system?

Mounjaro (tirzepatide) typically takes around 25 days to completely leave your system after your last dose. However, its exact duration can vary depending on some individual factors:

Factors influencing clearance:

  • Your metabolism: Individuals with faster metabolisms may clear the medication quicker, while those with slower metabolisms might take longer.
  • Kidney function: Kidneys play a role in eliminating Mounjaro. If your kidney function is impaired, the medication may stay in your system for a longer period.
  • Liver function: The liver also contributes to Mounjaro’s clearance. Liver impairment can similarly lead to extended medication presence.
  • Dose: Higher doses might take slightly longer to be fully eliminated compared to lower doses.

Important details:

  • While the medication itself may be gone after 25 days, certain active metabolites (breakdown products) can linger for a bit longer. However, these metabolites generally don’t contribute significantly to Mounjaro’s therapeutic effects.
  • Even after the medication is out of your system, its effects might persist for some time. For example, lowered blood sugar levels or reduced appetite could stay for a while due to the long-lasting impact on your body’s metabolic processes.

  4. Clean the injection site: Use an alcohol wipe and let it air dry completely.


  1. Remove the pen cap: Pull the gray cap straight down to remove it.
  2. Unlock the pen: Turn the dial until the click sound and green indicator appear.
  3. Prepare the injection site: Pinch the chosen area gently between your thumb and index finger.

  6. Release and withdraw: Let go of the button and remove the pen.


  1. Dispose of the pen: Place the used pen in the sharps container immediately.
  2. Apply gentle pressure: Hold the injection site with a clean gauze or tissue for a few seconds to prevent bleeding.
  3. Monitor the site: Keep an eye on the injection area for any redness, swelling, or pain. If something seems concerning, consult your doctor.

Why am i not losing weight on mounjaro? 

It’s totally understandable to feel frustrated if you’re not seeing the weight loss you expected with Mounjaro. Several factors could be contributing to this, and it’s important to remember that Mounjaro isn’t a magic bullet – it works best in conjunction with other lifestyle changes. Here are some potential reasons why you might not be losing weight on Mounjaro:


  • Calorie intake: Even with Mounjaro’s appetite-suppressing effects, overeating could still hinder weight loss. Ensure you’re tracking your calorie intake and staying within a healthy range for your goals.
  • Food choices: While Mounjaro can help you feel full, prioritizing nutrient-dense foods like fruits, vegetables, and whole grains will provide better long-term results than relying solely on processed or sugary options.

Physical activity:

  • Inactivity: Mounjaro works best when paired with regular physical activity. Aim for at least 150 minutes of moderate-intensity exercise per week to maximize its effectiveness.

Other factors:

  • Underlying medical conditions: Certain medical conditions can impact weight loss, even with medication. Discuss your concerns with your doctor to rule out any potential underlying causes.
  • Dosage: Your current Mounjaro dosage might not be optimal for your needs. Your doctor can adjust the dosage based on your progress and individual response.
  • Time frame: Remember, weight loss is a gradual process. While Mounjaro can accelerate it, it might take some time to see noticeable results. Be patient and stay consistent with your efforts.

Additional tips:

  • Track your progress: Keeping a daily log of your weight, food intake, and activity level can help you identify areas for improvement and stay motivated.
  • Seek support: Don’t hesitate to reach out to your doctor, a registered dietitian, or a therapist for personalized guidance and support.

Remember, it’s crucial to consult your healthcare provider to understand the specific reasons behind your weight loss plateau and determine the best course of action. They can adjust your dosage, suggest additional lifestyle changes, or rule out any underlying medical issues.

Does mounjaro need to be refrigerated?

Mounjaro ideally needs to be refrigerated between 36°F and 46°F (2°C and 8°C) to maintain its potency and effectiveness. However, there is some flexibility depending on the situation:


  • Ideal storage: Storing Mounjaro in the refrigerator is the best way to ensure its stability and efficacy. Place it in the original carton on a shelf, not in the door where it might be exposed to temperature fluctuations.

Room temperature:

  • Short-term storage: If you need to take Mounjaro with you on a trip or outing, it can be stored at room temperature (up to 86°F or 30°C) for up to 21 days. Avoid exposing it to direct sunlight or extreme heat.
  • Important note: Once you take Mounjaro out of the refrigerator, don’t put it back in. This can cause condensation to form, potentially affecting the medication’s quality.

What to eat on mounjaro?

Eating the right foods can significantly enhance your weight loss journey with Mounjaro by promoting satiety, managing blood sugar, and providing essential nutrients. Here are some dietary guidelines to follow:

Focus on:

  • Lean protein: Chicken, fish, lean meats, tofu, beans, and lentils provide lasting satiety and support muscle growth. Aim for 0.8 grams of protein per kilogram of body weight per day.
  • Whole grains: Opt for brown rice, quinoa, whole-wheat bread, and oats for sustained energy and fiber intake. These carbs digest slowly, preventing blood sugar spikes and crashes.
  • Non-starchy vegetables: Load up on broccoli, spinach, peppers, carrots, and leafy greens for essential vitamins, minerals, and fiber. They fill you up without adding too many calories.
  • Low-glycemic fruits: Berries, apples, pears, and grapefruit release sugar slowly, preventing blood sugar fluctuations and cravings. Limit high-glycemic fruits like bananas and mangoes.
  • Healthy fats: Include avocados, nuts, seeds, and olive oil in your diet for satiety, heart health, and nutrient absorption. Choose unsaturated fats over saturated and trans fats.
  • Hydration: Drink plenty of water throughout the day to feel full, suppress hunger, and aid digestion. Aim for 8 glasses of water daily.


  • Sugary drinks: Sodas, fruit juices, and energy drinks are loaded with empty calories and can trigger cravings. Stick to water, unsweetened tea, and black coffee.
  • Refined carbohydrates: White bread, pasta, pastries, and processed foods are high in refined carbs that spike blood sugar and lead to cravings.
  • Unhealthy fats: Fried foods, fatty meats, and processed snacks are high in saturated and trans fats, contributing to weight gain and heart health issues.
  • Highly processed foods: Avoid packaged foods, sugary snacks, and fast food as they are often low in nutrients and high in unhealthy ingredients.

When will mounjaro be available in Canada?

The good news is that Mounjaro (tirzepatide) is already available in Canada! It was approved by Health Canada in November 2023 and subsequently entered the Canadian market.

Remember that Mounjaro is a prescription medication and should only be used under the guidance of a qualified healthcare professional.

Can you take mounjaro and phentermine together?

Combining Mounjaro (tirzepatide) and phentermine is generally not recommended due to potential safety concerns and overlapping effects. Here’s why:

Safety risks:

  • Both Mounjaro and phentermine act on the central nervous system to suppress appetite and increase metabolism. Taking them together can significantly increase the risk of side effects like:
    • Elevated heart rate and blood pressure.
    • Anxiety and insomnia.
    • Headaches and dizziness.
    • Increased chance of heart attack or stroke, especially in people with pre-existing heart conditions.
  • Both medications can cause low blood sugar (hypoglycemia). Taking them together further increases this risk, potentially leading to dangerous complications.

Overlapping effects:

  • Both Mounjaro and phentermine work primarily by suppressing appetite and boosting metabolism. Taking them together might not provide any additional benefit and may even lead to diminishing returns.

Therefore, it’s crucial to discuss with your doctor if you’re considering combining Mounjaro and phentermine. They can assess your individual situation and determine if there are safer and more effective alternative approaches to achieve your weight loss goals.
