Serious Warnings and Precautions

Possible Risk of thyroid tumours, including cancer

As part of drug testing, semaglutide, the active ingredient in Aspen-Semaglutide was given to rats and mice in long term studies. In these studies, semaglutide caused both rats and mice to develop medullary thyroid tumours, some of which were cancer. It is not known if semaglutide will cause thyroid tumours or a rare type of thyroid cancer called medullary thyroid cancer in people. Do not use Aspen-Semaglutide if you or any of your family have ever had a type of thyroid cancer called medullary thyroid carcinoma (MTC), or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).

While taking Aspen-Semaglutide, tell your doctor if you get a lump or swelling in your neck, hoarseness, trouble swallowing or shortness of breath. These may be symptoms of thyroid cancer. You should discuss any safety concerns you have about the use of Aspen-Semaglutide with your doctor.

What Aspen-Semaglutide is used for:

  • Aspen-Semaglutide contains the active substance semaglutide. It is used to lower blood sugar (glucose) in adults with type 2 diabetes.
  • Aspen-Semaglutide is used on its own if your blood sugar level is not properly controlled by diet and exercise alone and you cannot use metformin.
  • Aspen-Semaglutide is used in combination with one or more other medicines for diabetes when they are not enough to control your blood sugar levels. These other medicines may include: oral antidiabetics (such as metformin, sulfonylurea, or sodium glucose co-transporter 2 inhibitor medicines) or insulin.
  • It is important that you keep following any diet and lifestyle advice from your doctor, pharmacist or nurse while using Aspen-Semaglutide.
  • Aspen-Semaglutide is not a substitute for insulin. Aspen-Semaglutide should not be used in patients with Type 1 diabetes mellitus (formerly known as insulin-dependent diabetes

    • mellitus or IDDM), or for treatment of diabetic ketoacidosis.

How Aspen-Semaglutide works:

Aspen-Semaglutide belongs to a class of medicines called GLP-1 receptor agonists (glucagon-like peptide-1 receptor agonists). Aspen-Semaglutide helps your body make more insulin when your blood sugar is high.

The ingredients in Aspen-Semaglutide are:

Medicinal ingredients: semaglutide. One mL solution for injection contains 1.34 mg semaglutide.

Non-medicinal ingredients: disodium phosphate dihydrate, phenol, propylene glycol, and water for injection.

Aspen-Semaglutide comes in the following dosage forms:

Aspen-Semaglutide is supplied as a clear and colourless solution for injection in a pre-filled pen.

Aspen-Semaglutide is available in a carton of 1 disposable, pre-filled, multi-dose pen delivering doses of 0.25 mg or 0.5 mg, including 6 disposable needles. This pack size is intended to be used for dose escalation and maintenance treatment at the 0.5 mg dose. The pen contains 1.5 mL solution.

Aspen-Semaglutide is available in a carton of 1 disposable, pre-filled, multi-dose pen delivering only doses of 1 mg, including 4 disposable needles. This pack size is intended to be used for maintenance treatment at the 1 mg dose only. The pen contains 3 mL solution.

Do not use Aspen-Semaglutide if:

  • You are allergic to semaglutide or any of the other ingredients of this medicine.
  • You or a member of your family has ever had medullary thyroid cancer (MTC).
  • You have Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
  • You are pregnant or breastfeeding.

To help avoid side effects and ensure proper use, talk to your healthcare professional before you take Aspen-Semaglutide. Talk about any health conditions or problems you may have, including if you:

  • or a member of your family has or has had medullary thyroid carcinoma (MTC), or if you have Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
  • Have type 1 diabetes.
  • Have ever had diabetic ketoacidosis (increased ketones in the blood or urine).
  • Have ever had an allergic reaction to Aspen-Semaglutide.
  • Have a high heart rate (fast pulse).
  • Have ever had pancreatitis.
  • Are breastfeeding or plan to breastfeed.
  • Are pregnant or plan to become pregnant.
  • Have end stage renal disease.
  • Have gastrointestinal (digestive) problems, including severe vomiting, diarrhea and/or dehydration.
  • Have hepatic (liver) disease.
  • Have diabetic retinopathy.
  • Take blood thinners (ex. Warfarin/Coumadin).

Other warnings you should know about:

Food or liquid getting into lungs during anaesthesia or sedation

  • Some patients taking medicines like Aspen-Semaglutide have had problems with food or liquid from their stomach getting into their lungs while under general anaesthesia or sedation.

Tell your healthcare professional that you are taking Aspen-Semaglutide before you have a procedure that requires general anaesthesia or sedation.

Cardiovascular

Aspen-Semaglutide may increase heart rate and could cause changes known as PR prolongation, which are detected by electrocardiogram (ECG) tracings. Increased heart rate is the same as a faster pulse. These heart rhythm changes are more likely if you have heart disease, or if you are taking certain other drugs. It is important to follow your doctor's advice about the dose of Aspen-Semaglutide or about any special tests that you may need. See ‘Possible side effects from using Aspen-Semaglutide?’

Children and adolescents

Aspen-Semaglutide is not recommended in children and adolescents under 18 years as the safety and efficacy in this age group have not yet been established.

Pregnancy and breastfeeding

Tell your doctor if you are pregnant, think you might be pregnant, or are planning to become pregnant. Aspen-Semaglutide should not be used during pregnancy and for at least two months before a planned pregnancy because it is not known if it may affect your unborn child.

If you could become pregnant while using Aspen-Semaglutide, it is recommended to use contraception.

Do not use this medicine if you are breast-feeding. This is because it is not known if semaglutide passes into breast milk.

Driving and using machines

Low blood sugar (hypoglycemia) may affect your ability to concentrate. Avoid driving or using machines if you get any signs of low blood sugar. See Possible side effects from using Aspen-Semaglutide for the warning signs of low blood sugar. You may feel dizzy when taking Aspen-Semaglutide, especially if your dose is being increased. If you feel dizzy, avoid driving or using machines. Talk to your doctor for further information.

Severe and on-going stomach pain which could be due to acute pancreatitis

If you have severe and on-going pain in the stomach area – see a doctor straight away as this could be a sign of acute pancreatitis (inflamed pancreas).

Effects on the digestive system, including dehydration

During treatment with Aspen-Semaglutide, you may experience feeling sick (nausea) or being sick (vomiting), and diarrhea. These side effects can cause dehydration (loss of fluids). It is therefore important to drink plenty of fluids to prevent dehydration. Talk to your doctor if you have any questions or concerns.

Patients with delayed stomach emptying (gastroparesis)

If you have slow (delayed) stomach emptying (called gastroparesis), use of Aspen-Semaglutide may lead to serious or severe gastrointestinal adverse events. Talk to your doctor before using Aspen-Semaglutide.

Diabetic eye disease (retinopathy)

Fast improvements in blood sugar control may lead to a temporary worsening of diabetic eye disease. This may require treatment or lead to a loss of vision. You should inform your doctor if you have diabetic eye disease (retinopathy) or if you experience eye problems during treatment with Aspen-Semaglutide.

Sudden changes to your eyesight

If you notice a sudden loss of vision or rapidly worsening eyesight during treatment with this medicine, urgently contact your doctor. This may be caused by a very rare side effect called non-arteritic anterior ischaemic optic neuropathy (NAION). Your doctor will refer you for an eye examination by an ophthalmologist and you may have to stop treatment with this medicine.

Low blood sugar (hypoglycemia)

Taking a sulfonylurea medicine or insulin with Aspen-Semaglutide might increase the risk of getting low blood sugar levels (hypoglycemia). Your doctor may ask you to test your blood sugar levels. This will help your doctor decide if the dose of the sulfonylurea or insulin needs to be changed to reduce the risk of low blood sugar.

Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.

In particular, tell your doctor, pharmacist or nurse if you are using medicines containing any of the following:

  • Sulfonylurea
  • Insulin

Combining these medicines with Aspen-Semaglutide might increase the risk of getting low blood sugar (hypoglycemia). Please see Possible side effects from using Aspen-Semaglutide for the warning signs of low blood sugar. Your doctor may tell you to lower your regular dose levels of these drugs when adding Aspen-Semaglutide treatment.

The following may interact with Aspen-Semaglutide:

The following list includes some, but not all, of the drugs that may increase your heart rate. You should check with your doctor or pharmacist before taking any other medication with Aspen-Semaglutide:

  • Drugs to treat hypertension.
  • Drugs to treat heart failure.
  • Drugs to treat HIV infection.
  • Drugs to treat attention deficit-hyperactivity disorder.
  • Drugs to suppress appetite/cause weight loss.
  • Decongestants.
  • Drugs to treat asthma.

How to take Aspen-Semaglutide:

Aspen-Semaglutide is given as an injection under the skin (subcutaneous injection). Do not inject it into a vein or muscle. The best places to give the injection are the front of your thighs, the front of your waist (abdomen), or your upper arm.

Before you use the pen for the first time, your doctor or Diabetes Nurse Educator will show you how to use it.

Detailed instructions for use are on the other side of this leaflet.

Always use this medicine exactly as your doctor has told you. Check with your doctor, pharmacist or nurse if you are not sure.

You should use Aspen-Semaglutide once a week on the same day each week if possible. You can give yourself the injection at any time of the day – regardless of meals. To help you remember to inject Aspen-Semaglutide once a week only, it is recommended to note the chosen weekday (e.g. Wednesday) on the carton. You can also write the date on the carton every time you have injected Aspen-Semaglutide.

If necessary you can change the day of your weekly injection of Aspen-Semaglutide as long as it has been at least 2 days since your last injection of Aspen-Semaglutide.

Do not stop using Aspen-Semaglutide without talking to your doctor. If you stop using it, your blood sugar levels may increase.

Usual dose:

When you first start using Aspen-Semaglutide, the starting dose is 0.25 mg once a week for four weeks. After four weeks you should increase your dose to 0.5 mg once a week. Talk to your doctor before increasing your dose.

Your doctor may increase your dose to 1 mg once a week if your blood sugar is not controlled well enough with a dose of 0.5 mg.

Your doctor may increase your dose to 2 mg once a week if your blood sugar is not controlled well enough with a dose of 1 mg. Your doctor will prescribe you another medication if they decide you need a 2 mg weekly dose.

Do not change your dose unless your doctor has told you to.

Overdose:

If you use more Aspen-Semaglutide than you should, talk to your doctor straight away. You may get side effects such as feeling sick (nausea) or being sick (vomiting), or diarrhea.

If you think you, or a person you are caring for, have taken too much Aspen-Semaglutide, contact a healthcare professional, hospital emergency department, regional poison control centre or Health Canada’s toll-free number, 1-844 POISON-X (1-844-764-7669) immediately, even if there are no signs or symptoms.

Missed Dose:

If you forgot to inject a dose and:

  • It is 5 days or less since you should have used Aspen-Semaglutide, use it as soon as you remember. Then inject your next dose as usual on your scheduled day.
  • It is more than 5 days since you should have used Aspen-Semaglutide, skip the missed dose. Then inject your next dose as usual on your scheduled day.

Do not take an extra dose or increase the dose to make up for a missed dose.

Instructions on how to use Aspen-Semaglutide solution for injection in pre-filled pen

0.25 mg or 0.5 mg doses (1.5 mL)

Please read these instructions carefully before using your Aspen-Semaglutide pre-filled pen.

Talk to your doctor, nurse or pharmacist about how to inject Aspen-Semaglutide correctly.

Start by checking your pen to make sure that it contains Aspen-Semaglutide 0.25 mg or 0.5 mg doses, then look at the illustrations below to get to know the different parts of your pen and needle.

If you are blind or have poor eyesight and cannot read the dose counter on the pen, do not use this pen without help. Get help from a person with good eyesight who is trained to use the Aspen-Semaglutide pre-filled pen.

Your pen is a pre-filled dial-a-dose pen. It contains 2 mg of semaglutide, and you can select doses of 0.25 mg or 0.5 mg.

One unused pen contains:

  • 4 doses of 0.25 mg (starting dose) and 2 doses of 0.5 mg
  • or 4 doses of 0.5 mg.

Your pen is designed to be used with Unifine® Pentips 4 mm, 32G (0.23 mm) disposable needles. Disposable needles are included in the pack.

Aspen-Semaglutide pre-filled pen and needle (example)

Important information

Pay special attention to these notes, as they are important for safe use of the pen.

  1. 1. Prepare your pen with a new needle
  • Check the name and coloured label of your pen to make sure that it contains Aspen-Semaglutide 0.25 or 0.5 mg doses. This is especially important if you take more than one type of injectable medicine. Using the wrong medicine could be harmful to your health.
  • Pull off the pen cap.
  • Check that the solution in your pen is clear and colourless. Look through the pen window. If the solution looks cloudy or coloured, do not use the pen.
  • Take a new needle and tear off the paper tab.

    If the paper tab is broken, do not use the needle, as sterility is not guaranteed.

Make sure to attach the needle correctly.

  • Push the needle straight onto the pen.
  • Turn until it is on tight.

The needle is covered by two caps. You must remove both caps. If you forget to remove both caps, you will not inject any solution.

  • Pull off the outer needle cap and keep it for later. You will need it after the injection, to safely remove the needle from the pen.
  • Pull off the inner needle cap and throw it away. If you try to put it back on, you may accidentally stick yourself with the needle.

A drop of solution may appear at the needle tip. This is normal, but you must still check the flow if you use a new pen for the first time.

Do not attach a new needle to your pen until you are ready to take your injection.

Always use a new needle for each injection.

This may prevent blocked needles, contamination, infection and inaccurate dosing.

Never use a bent or damaged needle.
  1. 2. Check the flow with each new pen
  • If your pen is already in use, go to step 3 ‘Select your dose’. Only check the flow before your first injection with each new pen.
  • Turn the dose selector to the flow check symbol

right past ‘0’. Make sure the flow check symbol lines up with the pointer.

  • Hold the pen with the needle pointing up.

    Press and hold in the dose button until the dose counter returns to 0. The 0 must line up with the dose pointer.

    A drop of solution should appear at the needle tip.

A small drop may remain at the needle tip, but it will not be injected.

If no drop appears, repeat step 2 ‘Check the flow with each new pen’ up to 6 times. If there is still no drop, change the needle and repeat step 2 ‘Check the flow with each new pen’ once more.

Dispose of the pen and use a new one if a drop of solution still does not appear.

Always make sure that a drop appears at the needle tip before you use a new pen for the first time. This makes sure that the solution flows.

If no drop appears, you will not inject any medicine even though the dose counter may move. This may indicate a blocked or damaged needle.

If you do not check the flow before your first injection with each new pen, you may not get the prescribed dose and the intended effect of Aspen-Semaglutide.

  1. 3. Select your dose
  • Turn the dose selector until the dose counter shows your dose (0.25 mg or 0.5 mg).

    If you select the wrong dose, you can turn the dose selector forwards or backwards to the correct dose.

    The pen can dial up to a maximum of 0.5 mg. Note: The dose selector will extend as the dose is selected.

The dose selector changes the dose. Only the dose counter and dose pointer will show how many mg you select per dose.

You can select up to 0.5 mg per dose. When your pen contains less than 0.5 mg, the dose counter stops before 0.5 is shown.

The dose selector clicks differently when turned forwards, backwards or past the number of mg left. Do not count the pen clicks.

Always use the dose counter and the dose pointer to see how many mg you have selected before injecting this medicine.

Do not count the pen clicks.

Only doses of 0.25 mg or 0.5 mg must be selected with the dose selector. The selected dose must line up precisely with the dose pointer to ensure that you get a correct dose.

How much solution is left
  • To see how much solution is left, use the dose counter: Turn the dose selector until the dose counter stops.

    If it shows 0.5, at least 0.5 mg is left in your pen.

    If the dose counter stops before 0.5 mg, there is not enough solution left for a full dose of 0.5 mg.

If there is not enough solution left in your pen for a full dose, do not use it. Use a new Semaglutide Injection pen.
  1. 4. Inject your dose
  • Insert the needle into your skin as your doctor or nurse has shown you.
  • Make sure you can see the dose counter. Do not cover it with your fingers. This could interrupt the injection.
Press the button until the dose counter shows 0. The 0 must line up with the dose pointer. The dose button will retract into the device body, and the injection will be completed once the dose selector stops moving. An audible clicking sound will be emitted throughout the injection and will stop once the injection is fully delivered.
  • Continue pressing the dose button while keeping the needle in your skin. Count slowly to 6 while keeping the dose button pressed.
  • If the needle is removed earlier, you may see a stream of solution coming from the needle tip. If so, the full dose will not be delivered. If this occurs, contact your doctor or nurse for further guidance.
  • Remove the needle from your skin. You can then release the dose button. If blood appears at the injection site, press lightly.
You may see a drop of solution at the needle tip after injecting. This is normal and does not affect your dose.

Always watch the dose counter to know how many mg you inject. Hold the dose button down until the dose counter shows 0.

How to identify a blocked or damaged needle

  • If 0 does not appear in the dose counter after continuously pressing the dose button, you may have used a blocked or damaged needle.
  • In this case, you have not received any medicine even though the dose counter has moved from the original dose that you have set.

    How to handle a blocked needle

    Change the needle as described in step 5 ‘After your injection’ and repeat all steps starting with step 1 ‘Prepare your pen with a new needle’. Make sure you select the full dose you need.

    Never touch the dose counter when you inject. This can interrupt the injection.

  1. 5. After your injection

Always dispose of the needle after each injection to ensure convenient injections and prevent blocked needles. If the needle is blocked, you will not inject any medicine.

Unscrew the needle and dispose of it carefully as instructed by your doctor, nurse, pharmacist or local authorities.

  • Lead the needle tip into the outer needle cap on a flat surface without touching the needle or the outer needle cap.
  • Once the needle is covered, carefully push the outer needle cap completely on.
  • Unscrew the needle and dispose of it carefully.
  • Put the pen cap on your pen after each use to protect the solution from light.

Always dispose of the needle after each injection to ensure convenient injections and prevent blocked needles. If the needle is blocked, you will not inject any medicine.

When the pen is empty, throw it away without a needle on as instructed by your doctor, nurse, pharmacist or local authorities.

Never try to put the inner needle cap back on the needle. You may stick yourself with the needle.

Always remove the needle from your pen immediately after each injection.

This may prevent blocked needles, contamination, infection, leakage of solution and inaccurate dosing.

Further important information
  • Always keep your pen and needles out of the sight and reach of others, especially children.
  • Never share your pen or your needles with other people.
  • Caregivers must be very careful when handling used needles to prevent needle injury and cross-infection.
  • Use the table inside the lid of the carton to keep track of how many injections you have taken and when you took the injections.
Caring for your pen
Treat your pen with care. Rough handling or misuse may cause inaccurate dosing, which may lead to high blood sugar levels or abdominal discomfort such as nausea or vomiting.
  • Do not leave the pen in a car or another place where it can get too hot or too cold.
  • Do not inject Aspen-Semaglutide which has been frozen. If you do that, your blood sugar level may get too high or you might feel abdominal discomfort such as nausea or vomiting.
  • Do not inject Aspen-Semaglutide which has been exposed to direct sunlight. If you do that, your blood sugar level may get too high.
  • Do not expose your pen to dust, dirt or liquid.
  • Do not wash, soak or lubricate your pen. It may be cleaned with a mild detergent on a moistened cloth.
  • Do not drop your pen or knock it against hard surfaces. If you drop it or suspect a problem, attach a new needle and check the flow before you inject.
  • Do not try to refill your pen. Once empty, it must be disposed of.
  • Do not try to repair your pen or pull it apart.

Only the dose counter and dose pointer will show that 1 mg has been selected.

You can only select 1 mg per dose. When your pen contains less than 1 mg, the dose counter stops before 1 is shown.

The dose selector clicks differently when turned forwards, backwards or past 1 mg. Do not count the pen clicks.

Always use the dose counter and the dose pointer to see that 1 mg has been selected before injecting this medicine.

Do not count the pen clicks.

Only doses of 1 mg must be selected with the dose selector. 1 mg must line up precisely with the dose pointer to ensure that you get a correct dose.

How much solution is left
  • To see how much solution is left, use the dose counter: Turn the dose selector until the dose counter stops.

    If it shows 1, at least 1 mg is left in your pen.

    If the dose counter stops before 1 mg, there is not enough solution left for a full dose of 1 mg.

If there is not enough solution left in your pen for a full dose, do not use it. Use a new Aspen-Semaglutide pen.
  1. 4. Inject your dose
  • Insert the needle into your skin as your doctor or nurse has shown you.
  • Make sure you can see the dose counter. Do not cover it with your fingers. This could interrupt the injection.
  • Press the button until the dose counter shows 0. The 0 must line up with the dose pointer. The dose button will retract into the device body, and the injection will be completed once the dose selector stops moving. An audible clicking sound will be emitted throughout the injection and will stop once the injection is fully delivered.
  • Continue pressing the dose button while keeping the needle in your skin. Count slowly to 6.
  • If the needle is removed earlier, you may see a stream of solution coming from the needle tip. If so, the full dose will not be delivered. If you notice this, contact your doctor or nurse for further guidance.
  • Remove the needle from your skin. You can then release the dose button. If blood appears at the injection site, press lightly. .
You may see a drop of solution at the needle tip after injecting. This is normal and does not affect your dose.

Always watch the dose counter to know how many mg you inject. Hold the dose button down until the dose counter shows 0.

How to identify a blocked or damaged needle

  • If 0 does not appear in the dose counter after continuously pressing the dose button, you may have used a blocked or damaged needle.
  • In this case, you have not received any medicine – even though the dose counter has moved from the original dose that you have set.

How to handle a blocked needle

Change the needle as described in step 5 ‘After your injection’ and repeat all steps starting with step 1 ‘Prepare your pen with a new needle’. Make sure you select the full dose you need.

Never touch the dose counter when you inject. This can interrupt the injection.

  1. 5. After your injection

Always dispose of the needle after each injection to ensure convenient injections and prevent blocked needles. If the needle is blocked, you will not inject any medicine.

Unscrew the needle and dispose of it carefully as instructed by your doctor, nurse, pharmacist or local authorities.

  • Lead the needle tip into the outer needle cap on a flat surface without touching the needle or the outer needle cap.
  • Once the needle is covered, carefully push the outer needle cap completely on.
  • Unscrew the needle and dispose of it carefully.
  • Put the pen cap on your pen after each use to protect the solution from light.

Always dispose of the needle after each injection to ensure convenient injections and prevent blocked needles. If the needle is blocked, you will not inject any medicine.

When the pen is empty, throw it away without a needle on as instructed by your doctor, nurse, pharmacist or local authorities.

Never try to put the inner needle cap back on the needle. You may stick yourself with the needle.

Always remove the needle from your pen immediately after each injection.

This may prevent blocked needles, contamination, infection, leakage of solution and inaccurate dosing.

Further important information
  • Always keep your pen and needles out of the sight and reach of others, especially children.
  • Never share your pen or your needles with other people.
  • Caregivers must be very careful when handling used needles to prevent needle injury and cross-infection.
  • Use the table inside the lid of the carton to keep track of how many injections you have taken and when you took the injections.
Caring for your pen
Treat your pen with care. Rough handling or misuse may cause inaccurate dosing, which may lead to high blood sugar levels or abdominal discomfort such as nausea or vomiting.
  • Do not leave the pen in a car or another place where it can get too hot or too cold.
  • Do not inject Aspen-Semaglutide which has been frozen. If you do that, your blood sugar level may get too high or you might feel abdominal discomfort such as nausea or vomiting.
  • Do not inject Aspen-Semaglutide which has been exposed to direct sunlight. If you do that, your blood sugar level may get too high.
  • Do not expose your pen to dust, dirt or liquid.
  • Do not wash, soak or lubricate your pen. It may be cleaned with a mild detergent on a moistened cloth.
  • Do not drop your pen or knock it against hard surfaces. If you drop it or suspect a problem, attach a new needle and check the flow before you inject.
  • Do not try to refill your pen. Once empty, it must be disposed of.
  • Do not try to repair your pen or pull it apart.
