Semaglutide is a GLP-1 medication used to improve blood sugar control and support weight loss. Below are clear answers to the questions people most often ask about how it works, dosing, safety, and more.
What is semaglutide?
Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist, meaning it acts like the natural hormone GLP-1. It helps regulate blood sugar and promotes weight loss by increasing insulin when needed, reducing glucagon, slowing digestion, and reducing appetite.
How does semaglutide work?
Semaglutide activates GLP-1 receptors in the gut, pancreas, and brain. In practice this means it:
- Enhances insulin secretion when blood sugar is high, helping bring it back toward normal.
- Reduces glucagon, the hormone that raises blood sugar.
- Slows gastric emptying, so you feel full longer after meals.
- Acts on appetite centers in the brain, reducing hunger and making it easier to eat less.
What are the typical dosages?
Semaglutide comes as a once-weekly injection and as a daily oral tablet (Rybelsus is the oral brand). Both start at a low dose that is increased gradually over several weeks to reduce side effects. For weight management, the injectable is titrated up to a target maintenance dose; for type 2 diabetes, dosing is set by the treating clinician. Your exact dose and schedule are always determined by your clinician.
Are there contraindications or precautions?
- Thyroid cancer history: semaglutide is not recommended for people with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2.
- History of pancreatitis: discuss with your clinician, as caution is advised.
- Pregnancy or trying to conceive: semaglutide is not recommended; tell your clinician.
- Share your full medical history and medication list, including oral contraceptives, before starting.
What are common side effects?
The most common side effects are gastrointestinal: nausea, vomiting, diarrhea, and constipation. They are usually mild to moderate, most noticeable during dose increases, and tend to ease as your body adjusts. Report severe or persistent abdominal pain to your clinician, as it can signal a rarer problem such as pancreatitis or gallbladder issues.
How often is semaglutide taken?
The injectable form is taken once weekly on the same day each week. The oral form is taken once daily on an empty stomach with a small sip of water, following the specific instructions provided with it.
Can semaglutide be taken during pregnancy?
No. There is limited safety data in pregnancy, and semaglutide is not recommended if you are pregnant or trying to become pregnant. Talk with your clinician about appropriate options.
Does insurance cover semaglutide?
Coverage varies widely by plan and indication, so check your specific plan. At IVUSE+, compounded semaglutide is offered at a flat, transparent monthly price with medication, telehealth consultation, and shipping included, so there are no surprise costs.
