Introduction
Liraglutide (Victoza) is a GLP-1 receptor agonist used to improve blood sugar control in type 2 diabetes and reduce cardiovascular risk. It is given as a once-daily subcutaneous injection and works by stimulating insulin release and reducing glucagon. Most people experience gastrointestinal side effects early on that improve as the body adjusts.
Week-by-week timeline
Starting at 0.6 mg
Begin at 0.6 mg once daily to minimize nausea. Inject at the same time each day. Expect mild nausea, decreased appetite, and possible injection site reactions. Blood sugar may begin to lower slightly.
Increase to 1.2 mg
If 0.6 mg is tolerated, dose increases to 1.2 mg daily. Nausea usually peaks around this time then gradually improves. You may notice more consistent appetite suppression and modest weight loss.
Optional Increase to 1.8 mg
For additional glycemic control, dose may be raised to 1.8 mg. Blood sugar improvements become more pronounced. GI symptoms typically subside significantly by now.
Stabilization
Blood sugar levels stabilize and A1C reductions become measurable. Weight loss continues. Most patients tolerate the medication well and injection technique becomes routine.
Long-Term Effects
Continued A1C improvement expected, typically 1-1.5% reduction. Cardiovascular benefits accrue over time. Regular monitoring of kidney function and HbA1c every 3 months is recommended.
When to call your doctor
Contact your healthcare provider if you experience:
- Signs of pancreatitis: severe persistent abdominal pain radiating to the back
- Neck lump, hoarseness, or trouble swallowing (possible thyroid tumor)
- Severe allergic reaction: rash, swelling, or difficulty breathing
- Hypoglycemia when combined with insulin or sulfonylureas: shakiness, sweating, confusion
- Signs of severe dehydration from vomiting or diarrhea
- Persistent resting heart rate increase greater than 20 bpm
Tips for getting started
Inject at the same time each day regardless of meals. Rotate injection sites among abdomen, thigh, and upper arm. Store unused pens refrigerated; opened pens can stay at room temperature up to 30 days. Eating smaller, lower-fat meals helps manage nausea in the first weeks.
