Liraglutide (Victoza®) - Side Effects, Precautions, and Contraindications

What side effects can Liraglutide (Victoza®) cause?

The most common side effects are nausea and diarrhea. Some patients may also experience a decrease in appetite, stomach pain, vomiting, constipation. These side effects often get better in a few days or weeks, hence you are advised to continue taking the medicine. However, please speak to your doctor or pharmacist if the side effects continue or are very serious.


Another common side effect is low blood sugar, especially if Liraglutide is used together with other diabetes medicines like sulfonylureas (e.g. Glipizide, Gliclazide).


Symptoms of low blood sugar are weakness, dizziness, hunger, sweating, trembling, blurred vision, unsteady walk or fast heartbeat.
If you experience any of these low blood sugar symptoms, do the following immediately:
Step 1: Check your blood sugar level with a home blood sugar meter (glucometer) if available. If your blood sugar level is less than 4 mmol/L, take 15 grams of sugar such as:
- 3 glucose tablets or
- Half a glass of fruit juice or
- 3 teaspoons of sugar, honey or syrup
Step 2: You should feel better in about 15 minutes. If you have a home blood sugar meter, you should check your blood sugar level again.
Step 3: If your blood sugar level is still less than 4 mmol/L or you still have symptoms of low blood sugar, you should take another 15 grams of sugar.
If your symptoms still do not get better, see a doctor or go to the hospital immediately.

You may also experience some mild bruising, pain, irritation, itching and rash at the injection site.
