Victoza Side Effects
The most common side effects of Victoza include diarrhea, nausea, and constipation. However, most people are able to take it without any problems. When used by itself, Victoza is unlikely to cause dangerously low blood sugar. However, it is still a possibility, and you should seek prompt medical attention if you develop any of its symptoms, including blurry vision, shakiness, or extreme hunger.
As with any medicine, side effects are possible with Victoza® (liraglutide). However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Victoza. Your healthcare provider can discuss a more complete list with you.)
Common Side Effects of Victoza
Victoza has been studied thoroughly in clinical trials. In these studies, the side effects that occurred in a group of people taking Victoza (alone or in combination with other diabetes medications) were documented and compared to those that occurred in a similar group of people taking other diabetes medications (without Victoza). This way, it is possible to see what side effects occurred, how often they appeared, and how they compared to the groups taking other diabetes medications.
The following percentages come from the studies in which people took Victoza only, not in combination with other diabetes medications; thus, these numbers probably most fairly represent the actual likelihood of Victoza causing these adverse reactions. In other words, the results are not skewed by the simultaneous use of other diabetes medications.
In these studies, the most common Victoza side effects included:
- Nausea -- in up to 28.4 percent of people
- Diarrhea -- up to 17.1 percent
- Vomiting -- up to 10.9 percent
- Constipation -- up to 9.9 percent
- Upper respiratory tract infection (such as the common cold) -- up to 9.5 percent.
Other, slightly less common side effects (occurring in 5 to 7.4 percent of people) in such studies included:
Gastrointestinal problems (particularly nausea, diarrhea, or vomiting) usually are most common when people first start taking Victoza and generally improve gradually with time. Also, such reactions are more common with a higher Victoza dosage.
