What is Victoza?

Victoza is an anti-diabetic medicine. An active ingredient of Victoza is “liraglutide” which is a glucagon-like peptide-1. Victoza is available as 6mg/ml solution for injection in a pre-filled pen. One pre-filled pen contains 3ml of solution which contains 18mg Liraglutide.

Uses of Victoza

Victoza is used to lower blood glucose levels in type 2 diabetics. It should not be used in type 1 diabetics and patients with diabetic ketoacidosis. Victoza is not a first-line therapy for uncontrolled diabetes but is used in combination with other anti-diabetic drugs like metformin to achieve glycaemic control.

How does Victoza work?

  • Victoza stimulates the release of insulin from the pancreas which decreases blood sugar levels. Apart from this, it also lowers glucagon secretion (a hormone which increases blood glucose).
  • This mechanism also leads to delayed gastric emptying and reduced body weight by decreasing the appetite.
  • By controlling the blood glucose levels, Victoza decreases the incidence of kidney damage, heart problems, blindness, nerve problems etc.

How to Take Victoza?

  • Victoza can be injected subcutaneously in the abdomen, thigh or upper arm once daily at a fixed time every day.
  • Victoza should not be injected while it is cold as it can be very painful. It is always recommended to inject the solution while it is at room temperature.
  • Do not inject Victoza if the solution has become cloudy or has clumps in the container. Discard the solution if it is not clear and colourless.
  • Before injecting, make sure the site is clean and dry. Do not inject via intravenous or intramuscular route.
  • Victoza can be administered along with other oral anti-diabetic drugs like sulfonylureas and metformin but their dose should be altered to prevent hypoglycaemia.
  • Non-pharmacologic therapy (dietary modification, weight control, and exercise) is equally essential to reduce blood glucose levels along with Victoza therapy.

Common Dosage for Victoza?

  • There is no fixed dose regimen of Victoza for the treatment of diabetes. Constant monitoring of blood glucose levels and dose variation accordingly is a must.
  • To reduce the risk of side effects, your doctor may initially start from a low dose and gradually increase your dose based on your condition.
  • Victoza insulin is usually administered once a day at the same time every day.
  • To reduce the incidence of gastric side effects, the initial dose of Victoza is 0.6mg per day for one week. The dose can be increased to 1.2 mg per day the following week.
  • The daily dose can be increased up to 1.8mg per day if glycaemic control is not achieved with 1.2mg per day. A dose higher than 1.8mg is not recommended.
  • Dose adjustment of Victoza insulin is needed with a change in physical activity, time and amount of food intake, change in kidney and liver functions.
