Talk with your health care provider if you are not sure if you are pregnant or planning to become pregnant. Saxenda^® may harm your unborn baby

• are breastfeeding or plan to breastfeed. It is not known if Saxenda^® passes into your breast milk. You and your health care provider should decide if you will take Saxenda^® or breastfeed. You should not do both without talking with your health care provider first

Tell your health care provider about all the medicines you take, including prescription and 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 health care provider if you take diabetes medicines, especially sulfonylurea medicines or insulin.

• Inject your dose of Saxenda^® under the skin (subcutaneous injection) in your stomach area (abdomen), upper leg (thigh), or upper arm, as instructed by your health care provider. Do not inject into a vein or muscle
• Never share your Saxenda^® pen or needles with another person. You may give an infection to them, or get an infection from them

Saxenda^® may cause serious side effects, including:

• possible thyroid tumors, including cancer
• inflammation of the pancreas (pancreatitis). Stop using Saxenda^® and call your healthcare provider right away if you have severe pain in your stomach area (abdomen) that will not go away, with or without vomiting. You may feel the pain from your abdomen to your back
• gallbladder problems. Saxenda^® may cause gallbladder problems, including gallstones. Some gallbladder problems need surgery. Call your health care provider if you have any of the following symptoms: pain in your upper stomach (abdomen), fever, yellowing of your skin or eyes (jaundice), and clay-colored stools
• low blood sugar (hypoglycemia) in people with type 2 diabetes who also take medicines to treat type 2 diabetes. Saxenda^® can cause low blood sugar in people with type 2 diabetes who also take medicines used to treat type 2 diabetes (such as sulfonylureas). In some people, the blood sugar may get so low that they need another person to help them. If you take a sulfonylurea medicine, the dose may need to be lowered while you use Saxenda^®. Signs and symptoms of low blood sugar may include: shakiness, sweating, headache, drowsiness, weakness, dizziness, confusion, irritability, hunger, fast heartbeat, and feeling jittery. You should check your blood sugar before you start taking Saxenda^® and while you take Saxenda^®
• increased heart rate. Saxenda^® can increase your heart rate while you are at rest. Your health care provider should check your heart rate while you take Saxenda^®. Tell your health care professional if you feel your heart racing or pounding in your chest and it lasts for several minutes when taking Saxenda^®
• kidney problems (kidney failure). Saxenda^® may cause nausea, vomiting, or diarrhea leading to loss of fluids (dehydration). Dehydration may cause kidney failure, which can lead to the need for dialysis. This can happen in people who have never had kidney problems before. Drinking plenty of fluids may reduce your chance of dehydration. Call your health care provider right away if you have nausea, vomiting, or diarrhea that does not go away, or if you cannot drink liquids by mouth
• serious allergic reactions. Serious allergic reactions can happen with Saxenda^®. Stop using Saxenda^® and get medical help right away if you have any symptoms of a serious allergic reaction

Nausea is most common when first starting Saxenda^®, but decreases over time in most people as their body gets used to the medicine. Tell your health care professional if you have any side effect that bothers you or that does not go away.
