Can You Continue to Take Victoza After Being Off It for One Week
Liraglutide was the 163rd most commonly prescribed drug in the United States in 2017, with 3,802,464 prescriptions for the drug written that year. This fact is rather impressive, considering the FDA has approved more than 20,000 prescription drugs for the U.S. market. Because of the drug's popularity, it is important that consumers know more about this medication, including how long Victoza stays in your system.
The National Library of Medicine provides the following information regarding liraglutide half-life:
Mean effective half-life: 13 hours
Time to steady-state: approximately 3 days
Mean accumulation ratio: 1.4–1.5
Victoza has poor oral availability, according to the National Library of Medicine, and a bioavailability of 55 percent, according to DrugBank. Very little intact liraglutide is excreted in urine and feces, and low levels of liraglutide metabolites are present in plasma, which suggest that liraglutide completely degrades in the body.
FAQ
What is the half-life of Victoza?
The half-life of Victoza is 13 hours, according to the National Library of Medicine.
How long does it take to get Victoza out of your system?
With a 13-hour half-life, it would take about 3 days to get out of the patient's system. Sometimes, doctors may order therapeutic drug testing to ensure patients are taking their medications as directed and that the medications are working as they should. What should Victoza patients expect for therapeutic drug testing?
- Urine: Since liraglutide and its metabolites are not largely excreted through either urine or feces, urine testing for this medication is not likely
- Plasma: According to the FDA, "[l]iraglutide is extensively bound to plasma protein (>98%)"; as such, blood tests are a much more reliable way to detect levels of liraglutide in the body
Do Victoza side effects go away?
Victoza side effects usually go away with continued use as directed, as the body adjusts to treatment.

Does Victoza need to be refrigerated?
Victoza should be refrigerated at temperatures between 36ºF to 46ºF (2ºC to 8ºC) prior to its first use, according to the FDA. But, people may store it at room temperature or in the refrigerator after initial use.

What is Victoza?
Victoza is an injectable anti-diabetic drug regularly used with other diabetes medications. The generic drug liraglutide is often sold under the brand names Victoza 3-Pak, Victoza 2-Pak, and Saxenda.
What is Victoza Used For?
People with diabetes use Victoza along with diet and exercise to lower their blood sugar levels and to control their A1C(a blood test that detects blood sugar levels from the previous 3 months). Victoza can control blood sugar levels in adults and in children aged 10 and older who have type 2 diabetes when other medications have not worked well enough. When used along with a reduced calorie diet and exercise plan, this medication can help promote and maintain weight loss people who are overweight or obese and have weight-related medical problems.
Victoza can also reduce the risk of a heart attack, stroke, or death in adults with type 2 diabetes who also have heart and blood vessel disease.
How Does Victoza Work?
Victoza works by increasing the amount of insulin released by the pancreas and by decreasing the excessive release of glucagon. Namely, insulin "unlocks" body cells to allow the cells to absorb sugar, or glucose, from the bloodstream; absorption of glucose from the bloodstream allows blood sugar levels to drop. Glucagon is a hormone that stops the absorption of glucose from the bloodstream to prevent blood sugar levels from dropping too low. An excessive release of glucagon would thereby cause the body to maintain an unhealthy high blood sugar level, known as hyperglycemia.
How Long Does it Take for Victoza to Work?
It takes about two weeks for Victoza to lower blood sugar levels, according to the manufacturer's website.
