Nausea, vomiting, stomach upset, decreased appetite, diarrhea, or constipation may occur. Nausea usually lessens as you continue to use liraglutide. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Vomiting/diarrhea that doesn't stop may result in dehydration. Contact your doctor promptly if you notice any symptoms of dehydration, such as unusual dry mouth/thirst, fast heartbeat, or dizziness/lightheadedness.
Tell your doctor right away if you have any serious side effects, including: signs of kidney problems (such as change in the amount of urine), mental/mood changes (such as depression, thoughts of suicide).
Get medical help right away if you have any very serious side effects, including: signs of pancreatitis or gallbladder disease (such as nausea/vomiting that doesn't stop, severe stomach/abdominal pain).
Although liraglutide by itself usually does not cause low blood sugar (hypoglycemia), low blood sugar may occur if this drug is prescribed with other diabetes medications. Talk with your doctor or pharmacist about whether the dose(s) of your other diabetes medication(s) needs to be lowered. Drinking large quantities of alcohol, not getting enough calories from food, or doing unusually heavy exercise may also lead to low blood sugar. Symptoms may include sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, headache, or tingling hands/feet. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, raise your blood sugar quickly by eating a quick source of sugar such as table sugar, honey, candy, or drinking a glass of fruit juice or non-diet soda. Check with your doctor or pharmacist to find out what you should do if you miss a meal.
Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, and fruity breath odor. If these symptoms occur, tell your doctor right away. Your doctor may need to adjust your diabetes medication(s).
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any of the following symptoms of a serious allergic reaction: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
