How does this medication work? What will it do for me?
Liraglutide belongs to the class of medications called human glucagon-like peptides. It is used for chronic (long-term) management of body weight, together with reduced caloric intake and increased physical activity. It may be prescribed for people with a body mass index (BMI) of 30 kg/m² or more, or people with a BMI of 27 kg/m² who also have another weight-related illness, such as high blood pressure, type 2 diabetes, or dyslipidemia (high cholesterol).
It is also used with decreased caloric intake and increased physical activity for long-term body weight management for adolescents between 12 and 18 years of age who have obesity, as diagnosed by a doctor. Liraglutide helps with weight control by affecting sensations of hunger, causing a decrease in appetite and food intake. It slows down the passage of food from the stomach into the intestine, causing the person to "feel full" for longer after a meal. It also decreases the maximum glucose level in the blood and the amount of insulin needed for the body to use the glucose.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
How should I use this medication?
The recommended starting dose of liraglutide is 0.6 mg daily injected subcutaneously (under the skin) on your stomach area (abdomen), upper thigh, or upper arm, exactly as instructed by your doctor. It can be injected at any time of the day, without regard to meals. After one week, your doctor will increase the dose to 1.2 mg once daily, gradually increasing the dose to the recommended 3 mg daily. This gradual increase of the dose should minimize side effects on the digestive system. Adolescents should follow the same gradual increase in dose. If 3 mg daily produces unacceptable side effects, the dose may be reduced to 2.4 mg daily.
Your doctor or nurse will assist you in the preparation and injection of your first dose (or first few doses) and can teach you how to give yourself the injection at home. Do not attempt to inject this medication on your own until you completely understand how to inject a dose. If you are unsure of how to prepare or administer a dose, ask a health care professional to clarify for you. If you are having difficulty giving yourself injections, ask a family member or other caregiver for help if they are willing to become involved with your treatment and are willing to learn how to give you your injections.
Use a different injection site for each dose. Avoid injecting this medication into an area of skin that is sore, red, infected, or otherwise damaged.
Liraglutide should be clear and colourless. Do not use liraglutide if you notice particles or anything unusual in the appearance of the solution.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Breast cancer: There may be an increased risk of developing breast cancer when using liraglutide. Talk to your doctor if you have any concerns.
Gallstones: Liraglutide has been associated with an increase in gallstone formation. Gallstones often form when there is significant or fast weight loss. If you experience symptoms of gallstones, such as nausea and vomiting, pain under the right shoulder or between the shoulder blades or severe abdominal pain, contact your doctor as soon as possible.
Heart problems: This medication may increase heart rate and may affect how electrical impulses travel through the heart muscle. If you have heart disease (e.g., recent heart attack, angina, heart failure) or an abnormal heart rhythm (e.g., heart block or fast heart rate), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Intestinal problems: The safety and effectiveness of using this medication for people with inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis) or who have slowed movement through the intestinal tract due to diabetes have not been established. If you have digestive system problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney function: Liraglutide can cause dehydration as a result of digestive system side effects such as diarrhea, which in turn, can affect kidney function. Make sure you drink enough fluids to prevent dehydration. The safety and effectiveness of using this medication for people with reduced kidney function has not been studied. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: The safety and effectiveness of using this medication for people with reduced liver function have not been studied. If you have reduced liver function or liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Low blood glucose (hypoglycemia): People who use liraglutide may experience low blood sugar. This may be more likely if you are also taking a sulfonylurea (e.g., glyburide, gliclazide) to control high blood sugar. If you experience symptoms of hypoglycemia such as a cold sweat, nervousness or shakiness, fast heartbeat, headache, hunger, confusion, lightheadedness, weakness, and numbness or tingling of the tongue or lips, contact your doctor.
Pancreatitis (inflammation of the pancreas): Liraglutide can cause pancreatitis. If you experience symptoms of pancreatitis such as severe and persistent abdominal pain that may move to the back with or without vomiting, contact your doctor immediately. If you have previously had pancreatitis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Thyroid cancer: In rare cases, people have developed thyroid cancer while using liraglutide. People with a personal or family history of thyroid cancer or people who have multiple endocrine neoplasia syndrome type 2 (a disease where people have tumours in more than one gland in their body) should not use this medication.
Suicidal or depressed behaviour: People using liraglutide may experience new or worsening symptoms of depression, thoughts of self-harm, or change in mood and behavior. If you experience these side effects or notice them in a family member who is taking this medication, contact your doctor immediately.
Pregnancy: Liraglutide has not been studied for use by pregnant women and should not be used during pregnancy. If you become pregnant while using this medication, contact your doctor immediately.
