The short version
Semaglutide is a GLP-1 receptor agonist. GLP-1 is a hormone pathway involved in appetite, glucose regulation, and signals between the gut, brain, and pancreas.
Prescription GLP-1 therapy is not just a weight-loss shortcut. The right patient, dose, titration speed, medication history, and follow-up plan all matter.
Why review comes first
A clinician should screen for contraindications, pregnancy status, pancreatitis history, gallbladder issues, gastrointestinal conditions, diabetes medications, and other factors that can affect safety.
Pacific RX uses intake answers to support physician review before a prescription is issued or payment is captured.
What to expect
Many patients start with a lower dose and titrate gradually. Side effects can include nausea, constipation, reflux, reduced appetite, and dehydration risk.
Nutrition, protein intake, hydration, resistance training, and follow-up are part of making treatment sustainable.
