Victoza which is used to treat type 2 diabetes is pretty safe to take and I used to take it until I was switched to a different diabetic medicine and it did also help me lose some weight which I needed to lose as well.
But you may experience some side effects such as diarrhea, loss of appetite, indigestion, Vomiting, Upset Stomach, Nausea, headache and dizziness.
Some other side effects include High Blood Levels Of The Lipase Enzyme, Throwing Up and Constipation.
If you do experience some side effects from Victoza you should speak to your doctor about just in case they might want you to switch to a different medicine.
