Liraglutide Drug Interactions
Also known as: Victoza
Liraglutide (Victoza) is a type of medicine that mimics a natural hormone in your body. It is prescribed to help adults and children aged 10 and older with type 2 diabetes manage their blood sugar levels, and it can also lower the risk of serious heart problems like heart attack or stroke in adults with type 2 diabetes and existing heart disease. It works by helping your body release insulin when needed and reducing the amount of sugar your liver makes.Liraglutide has 2 documented drug interactions in our database, including 0 contraindicated, 0 major, 1 moderate, and 1 minor interactions.

Combining semaglutide and liraglutide, both GLP-1 receptor agonists, is generally not recommended. This combination is unlikely to provide additional glycemic control or weight loss benefits beyond monotherapy, but significantly increases the risk of dose-dependent adverse effects.
Mechanism
Both semaglutide and liraglutide act as glucagon-like peptide-1 (GLP-1) receptor agonists, stimulating insulin secretion, suppressing glucagon release, slowing gastric emptying, and promoting satiety. Concomitant use leads to additive pharmacological effects on the GLP-1 receptor.
Clinical Management
Concomitant use of semaglutide and liraglutide should be avoided. If a patient is not achieving desired outcomes on one GLP-1 agonist, consider optimizing the dose, switching to a different class of antidiabetic medication, or adding another agent from a different class, rather than combining two GLP-1 agonists. Monitor for increased gastrointestinal side effects if inadvertently co-administered.
Metformin and liraglutide are often used together to improve glycemic control in patients with type 2 diabetes. While generally beneficial, combining these medications can increase the risk of hypoglycemia, particularly when other glucose-lowering agents are also used.
Mechanism
Both metformin and liraglutide work through different mechanisms to lower blood glucose. Metformin primarily reduces hepatic glucose production, while liraglutide enhances glucose-dependent insulin secretion and slows gastric emptying. Their additive effects on glucose lowering can lead to a greater reduction in blood sugar.
Clinical Management
Patients should be monitored for signs and symptoms of hypoglycemia, especially when initiating or titrating either medication. If hypoglycemia occurs, dose adjustments of one or both medications, or other concomitant glucose-lowering agents, may be necessary. Educate patients on recognizing and treating hypoglycemia.
