Talk to your doctor about the risks of taking semaglutide.
Why is this medication prescribed?
Semaglutide is used for the following:
- to control blood sugar levels in certain people with type 2 diabetes (condition in which blood sugar is too high because the body does not make or use insulin normally).
- to reduce the risk of a heart attack, stroke, or death in people with heart and blood vessel disease who have type 2 diabetes or who are obese or overweight.
- to assist with weight loss and maintenance in certain people who are obese or overweight and have at least one weight-related medical problem.
Semaglutide is in a class of medications called incretin mimetics. It works by helping the pancreas to release the right amount of insulin when blood sugar levels are high. Insulin helps move sugar from the blood into other body tissues where it is used for energy. Semaglutide also works by slowing the movement of food through the stomach.
How should this medicine be used?
Semaglutide comes as a tablet to take by mouth. Take on an empty stomach once a day when you wake up. Take semaglutide with a sip of water (no more than 4 ounces [120 mL]) at least 30 minutes before eating a meal or snack, drinking, or taking any other medications. Your doctor may gradually increase your dose, depending on your response to semaglutide.
Take semaglutide exactly as directed. Do not take more or less of it or take it more often than directed by the package label or prescribed by your doctor.
Swallow the tablets whole; do not split, chew, or crush them.
Semaglutide controls diabetes and weight loss but does not cure it. Continue to take semaglutide even if you feel well. Do not stop taking semaglutide without talking with your doctor.
