What is Saxenda?

Saxenda is an injectable prescription medicine used for adults with obesity or overweight (excess weight) who also have weight related medical problems, and children aged 12 to 17 years with a body weight above 132 pounds (60 kg) and obesity to help them lose weight and keep the weight off.

Saxenda should be used with a reduced calorie diet and increased physical activity. Saxenda and Victoza have the same active ingredient, liraglutide, and should not be used together or with other GLP-1 receptor agonist medicines. It is not known if Saxenda is safe and effective when taken with other prescription, over-the-counter medicines, or herbal weight loss products.

It is not known if Saxenda is safe and effective in children under 12 years of age. It is not known if Saxenda is safe and effective in children aged 12 to 17 years with type 2 diabetes.

Description

SAXENDA contains liraglutide, an analog of human GLP-1 and acts as a GLP-1 receptor agonist. The peptide precursor of liraglutide, produced by a process that includes expression of recombinant DNA in Saccharomyces cerevisiae, has been engineered to be 97% homologous to native human GLP-1 by substituting arginine for lysine at position 34. Liraglutide is made by attaching a C-16 fatty acid (palmitic acid) with a glutamic acid spacer on the remaining lysine residue at position 26 of the peptide precursor. The molecular formula of liraglutide is C172H265N43O51 and the molecular weight is 3751.2 Daltons. The structural formula (Figure 1) is:

SAXENDA injection is a sterile, aqueous, clear, colorless or almost colorless solution for subcutaneous use. Each 1 mL of SAXENDA solution contains 6 mg of liraglutide and the following inactive ingredients: disodium phosphate dihydrate, 1.42 mg; propylene glycol, 14 mg; phenol, 5.5 mg; and water for injection. SAXENDA has a pH of approximately 8.15, hydrochloric acid or sodium hydroxide may be added to adjust pH. Each pre-filled pen contains a 3 mL solution of SAXENDA equivalent to 18 mg liraglutide (free-base, anhydrous).

Mechanism of Action

Liraglutide is an acylated human glucagon-like peptide-1 (GLP-1) receptor agonist with 97% amino acid sequence homology to endogenous human GLP-1(7-37). Like endogenous GLP-1, liraglutide binds to and activates the GLP-1 receptor, a cell-surface receptor coupled to adenylyl cyclase activation through the stimulatory G-protein, Gs. Endogenous GLP-1 has a half-life of 1.5-2 minutes due to degradation by the ubiquitous endogenous enzymes, dipeptidyl peptidase 4 (DPP-4) and neutral endopeptidases (NEP). Unlike native GLP-1, liraglutide is stable against metabolic degradation by both peptidases and has a plasma half-life of 13 hours after subcutaneous administration. The pharmacokinetic profile of liraglutide, which makes it suitable for once-daily administration, is a result of self-association that delays absorption, plasma protein binding, and stability against metabolic degradation by DPP-4 and NEP.

GLP-1 is a physiological regulator of appetite and calorie intake, and the GLP-1 receptor is present in several areas of the brain involved in appetite regulation. In animal studies, peripheral administration of liraglutide resulted in the presence of liraglutide in specific brain regions regulating appetite, including the hypothalamus. Although liraglutide activated neurons in brain regions known to regulate appetite, specific brain regions mediating the effects of liraglutide on appetite were not identified in rats.

What is the most important information I should know about Saxenda?

Do not share your Saxenda pen with others even if the needle has been changed. You may give other people a serious infection or get a serious infection from them.

Serious side effects may happen in people who take Saxenda, including:

Possible thyroid tumors, including cancer. Tell your healthcare provider if you get a lump or swelling in your neck, hoarseness, trouble swallowing, or shortness of breath. These may be symptoms of thyroid cancer. In studies with rats and mice, Saxenda and medicines that work like Saxenda caused thyroid tumors, including thyroid cancer. It is not known if Saxenda will cause thyroid tumors or a type of thyroid cancer called medullary thyroid carcinoma (MTC) in people.

Do not use Saxenda 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).

Who should not use Saxenda?

Do not use Saxenda 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).
  • you are allergic to liraglutide or any of the ingredients in Saxenda. See the end of this Medication Guide for a complete list of ingredients in Saxenda.
  • are pregnant or plan to become pregnant. Saxenda may harm your unborn baby.

What should I tell my healthcare provider before using Saxenda?

Before taking Saxenda, tell your healthcare provider about all of your medical conditions, including if you:

  • are taking certain medicines called GLP-1 receptor agonists.
  • have severe problems with your stomach, such as slowed emptying of your stomach (gastroparesis) or problems with digesting food.
  • have or have had problems with your pancreas, kidneys or liver.
  • have or have had depression or suicidal thoughts, or mental health issues.
  • are breastfeeding or plan to breastfeed. It is not known if Saxenda passes into your breast milk. You and your healthcare provider should decide if you will use Saxenda or breastfeed.

Tell your healthcare provider about all the medicines you take including prescription, over-the-counter medicines, vitamins, and herbal supplements. Saxenda slows stomach emptying and can affect medicines that need to pass through the stomach quickly. Saxenda may affect the way some medicines work and some other medicines may affect the way Saxenda works.

Tell your healthcare provider if you take diabetes medicines, especially insulin and sulfonylurea medicines. Talk with your healthcare provider if you are not sure if you take any of these medicines.

How should I use Saxenda?

Instructions for use for Saxenda

  • Read these instructions carefully before using your Saxenda pen.
  • Do not use your pen without proper training from your healthcare provider. Make sure that you know how to give yourself an injection with the pen before you start your treatment.
  • Warning – 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 Saxenda pen.
  • You can refresh your training at any time by watching the online training video at WWW.SAXENDA.COM.
  • Start by checking your pen to make sure that it contains Saxenda, then look at the pictures below to get to know the different parts of your pen and needle.
    Your pen is a prefilled, dial-a-dose, single-patient-use pen. It contains 18 mg of liraglutide, and you can select doses of 0.6 mg, 1.2 mg, 1.8 mg, 2.4 mg and 3 mg. Your pen is made to be used with NovoFine or NovoTwist disposable needles up to a length of 8 mm. Pen needles are not included with your Saxenda pen.

NovoFine pen

Step 1. Prepare your pen with a new needle

  • Wash your hands with soap and water.
  • Check the name and colored label of your pen, to make sure that it contains Saxenda. This is especially important if you take more than 1 type of medicine.
  • Pull off the pen cap.

Pull off the pen cap.

  • Check that Saxenda in your pen is clear and colorless.
    Look through the pen window. If Saxenda looks cloudy, do not use the pen.

Check the Saxenda is clear and colourless.

  • Take a new needle, and tear off the paper tab.

Tear paper off new needle.

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

Push needle into pen and turn until tight.

  • Pull off the outer needle cap. Do not throw it away.

Pull off outer needle cap and keep it.

  • Pull off the inner needle cap and throw it away.A drop of Saxenda may appear at the needle tip. This is normal, but you must still check the Saxenda flow, if you use a new pen for the first time.Warning. Always use a new needle for each injection.
    This will prevent contamination, infection, leakage of Saxenda, and blocked needles leading to the wrong dose.Never use a bent or damaged needle.

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

Pull off inner needle cap and discard.

Step 2. Check the Saxenda flow with each new pen.

  • Check the Saxenda flow before your first injection with each new pen.
    If your Saxenda pen is already in use, go to Step 3 “Select your dose”.
  • Turn the dose selector until the dose counter shows the flow check symbol.

Check the Saxenda flow.

  • Hold the pen with the needle pointing up.
    Press and hold in the dose button until the dose counter shows 0. The 0 must line up with the dose pointer.
    A drop of Saxenda will appear at the needle tip.
  • If no drop appears, repeat Step 2 above as shown in Figures G and H up to 6 times. If there is still no drop, change the needle and repeat Step 2 as shown in Figures G and H 1 more time.Do not use the pen if a drop of Saxenda still does not appear. Contact Novo Nordisk at 1-844-363-4448.
    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 Saxenda flows.
    If no drop appears, you will not inject any Saxenda, even though the dose counter may move. This may mean that there is a blocked or damaged needle.A small drop may remain at the needle tip, but it will not be injected.Only check the Saxenda flow before your first injection with each new pen.

Hold the pen with the needle pointing up. Press and hold in the dose button until the dose counter shows 0. The 0 must line up with the dose pointer. A drop of Saxenda will appear at the needle tip.

Step 3. Select your dose

  • Turn the dose selector until the dose counter shows your dose (0.6 mg, 1.2 mg, 1.8 mg, 2.4 mg or 3 mg).
    Make sure you know the dose of Saxenda you should use.
    If you select the wrong dose, you can turn the dose selector forward or backwards to the correct dose.Always use the dose counter and the dose pointer to see how many mg you select.You will hear a “click” every time you turn the dose selector. Do not set the dose by counting the number of clicks you hear.Do not use the pen scale to set the dose. It does not show exactly how much Saxenda is left in your pen.

    Only doses of 0.6 mg, 1.2 mg, 1.8 mg, 2.4 mg or 3 mg can be selected with the dose selector. The selected dose must line up exactly with the dose pointer to make sure that you get a correct dose.

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

    You can select up to 3 mg each dose. When your pen contains less than 3 mg the dose counter stops before 3 mg is shown.

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

Select the dose of Saxenda.

InformationHow much Saxenda is left?

  • The pen scale shows you about how much Saxenda is left in your pen.

Look at the pen scale to see how much Saxenda is left in the pen.

  • To see how much Saxenda is left, use the dose counter:Turn the dose selector until the dose counter stops.
    If it shows 3, at least 3 mg are left in your pen. If the dose counter stops before 3 mg, there is not enough Saxenda left for a full dose of 3 mg.If you need more Saxenda than what is left in your pen:Only if trained or told by your healthcare provider, you may split your dose between your current pen and a new pen. Use a calculator to plan the doses as instructed by your healthcare provider.

    Be very careful to calculate correctly.

    If you are not sure how to split your dose using 2 pens, then select and inject the dose you need with a new pen.

View the dose counter to see how much is left.

Step 4. Inject your dose

  • Insert the needle into your skin as your healthcare provider has shown you.
  • Make sure you can see the dose counter. Do not cover it with your fingers. This could stop the injection.

Inject dose.

  • Press and hold down the dose button until the dose counter shows 0. The 0 must line up with the dose pointer. You may then hear or feel a click.

Press and hold down the dose button until the dose counter shows 0.

  • Keep the needle in your skin after the dose counter has returned to 0 and count slowly to 6.
  • If the needle is removed earlier, you may see a stream of Saxenda coming from the needle tip. If this happens, the full dose will not be delivered.

Count slowly to six.

  • Remove the needle from your skin.
    If blood appears at the injection site, press lightly. Do not rub the area.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.
  • If this happens you have not received any Saxenda 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, 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 stop the injection.

You may see a drop of Saxenda at the needle tip after injecting. This is normal and does not affect your dose.

Remove the needle from your skin.

Step 5. After your injection

  • Carefully remove the needle from the pen. Do not put the needle caps back on the needle, to avoid needle sticks.

Carefully remove the needle from the pen.

  • Place the needle in a sharps container right away to reduce the risk of needle sticks.

Place the needle in a sharps container.

  • Put the pen cap on your pen after each use to protect Saxenda from light.

Put the pen cap back on.

If you do not have a sharps container, follow a 1-handed needle recapping method. Carefully slip the needle into the outer needle cap. Dispose of the needle in a sharps container as soon as possible.

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. This prevents contamination, infection, leakage of Saxenda, and blocked needles leading to the wrong dose. If the needle is blocked, you will not inject any Saxenda.

Always dispose of the needle after each injection.

  • Do not throw away in the household trash. Put the needle and any empty Saxenda pen or any pen used for 30 days still containing Saxenda in a FDA-cleared sharps disposal container right away after use.
  • If you do not have a FDA-cleared sharps disposal container, you may use a household container that is:
    • made of a heavy-duty plastic
    • can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out upright and stable during use
    • leak-resistant
    • properly labeled to warn of hazardous waste inside the container
  • When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should throw away used needles and syringes. For more information about the safe sharps disposal, and for specific information about sharps disposal in the state that you live in, go to the FDA’s website at: HTTP://WWW.FDA.GOV/SAFESHARPSDISPOSAL
  • Do not dispose of your used sharps disposal container in your household trash unless your community guidelines permit this. Do not recycle your used sharps disposal container.
  • Safely dispose of Saxenda that is out of date or no longer needed.

Carefully slip the needle into the outer needle cap and dispose in a sharps container as soon as possible if a container is not to hand straight away.

ImportantImportant
