people are taking charge of their type 2 diabetes with non-insulin victoza®. for a while, i took a pill to lower my blood sugar. but it didn't get me to my goal. so i asked my doctor about victoza®. he said victoza® works differently than pills. and comes in a pen. victoza® is proven to lower blood sugar and a1c. it's taken once a day, any time. victoza® is not for weight loss, but it may help you lose some weight. victoza® works with your body to lower blood sugar in 3 ways: in the stomach, the liver, and the pancreas. vo: victoza® is an injectable prescription medicine that may improve blood sugar in adults with type 2 diabetes when used with diet and exercise. it is not recommended as the first medication to treat diabetes and should not be used in people with type 1 diabetes or diabetic ketoacidosis. victoza® has not been studied with mealtime insulin.

victoza® is not insulin. do not take victoza® if you have a personal or family history of medullary thyroid cancer, multiple endocrine neoplasia syndrome type 2, or if you are allergic to victoza® or any of its ingredients. symptoms of a serious allergic reaction may include itching, rash, or difficulty breathing. tell your doctor if you get a lump or swelling in your neck. serious side effects may happen in people who take victoza®, including inflammation of the pancreas (pancreatitis). stop taking victoza® and call your doctor right away if you have signs of pancreatitis such as severe pain that will not go away in your abdomen or from your abdomen to your back, with or without vomiting. tell your doctor about all the medicines you take and if you have any medical conditions. taking victoza® with a sulfonylurea or insulin may cause low blood sugar. the most common side effects are headache, nausea, diarrhea, and vomiting. side effects can lead to dehydration, which may cause kidney problems. if your pill isn't giving you the control you need ask your doctor

about non-insulin victoza®. it's covered by most health plans. this man you see here has been arrested for allegedly spraying poisonous chemicals in michigan at produce and food bars at grocery stores. here's the latest. >> reporter: the fbi arrested the man in this photograph after they say he was caught spraying a mixture of hand sanitizer and rat poison on produce at three michigan grocery stores, including whole foods, meyer, and plum market, all in ann arbor. rat poison can prevent blood from clotting after initial contact and can irritate the skin when touched. >> it's very creepy. >> i'd like to wring his neck. >> reporter: investigators say the man reportedly confessed to the crime and was picked up after tips from the public. >> we ended up with numerous leads off of that.
