Your first month on a GLP-1 medication is mostly about starting low, building a weekly routine, and checking in with your clinician. Many GLP-1 medications are given by injection once a week, and doses increase gradually over several weeks. Here is what the first month can look like, based on FDA labeling, so you can feel prepared for your conversation with a clinician.
Starting Low: How GLP-1 Dose Escalation Works
GLP-1 medications are typically started at a low dose that is raised in steps, so your body can adjust. For one FDA-approved semaglutide product for weight management, the FDA label lists a starting dose of 0.25 mg once weekly for weeks 1 through 4, then 0.5 mg for weeks 5 through 8, with further steps after that. The label also says a clinician may consider delaying escalation by four weeks if a dose is not tolerated. That schedule belongs to one product, and your own plan comes from your clinician, who tailors it to your history and goals. Month one is the starting phase of a longer plan.
Building Your Weekly Injection Routine
Most GLP-1 injections are given once a week under the skin. The label says to inject into the abdomen, thigh, or upper arm, and notes that the injection site and time of day can change without a dose adjustment. Picking a regular day, such as Sunday morning, makes the habit easy to remember, and a phone reminder helps. Cleveland Clinic lists the abdomen, outer thighs, upper buttocks, and backs of the arms as common sites. Your pharmacy provides instructions, and your clinician can walk you through your device at your first follow-up. A simple log of your injection day, site, and how you feel gives you useful notes for your next visit.
What to Track and Discuss During Month One
Appetite and fullness are the changes most people ask about. GLP-1 medications act on brain areas that control hunger and fullness, which Cleveland Clinic describes as the main route to weight loss. Your clinician will ask how hunger feels, how your energy is, and what you notice day to day, then adjust the pace of your plan based on how you are doing. Bring your log to follow-up visits, along with questions and any lab results, so every check-in builds on the last. Helpful items to track:
- Injection day, site, and dose
- Appetite, fullness, and meal sizes
- Questions for your next visit
Frequently Asked Questions
How Often Are GLP-1 Medications Given?
Many are given once a week as an injection under the skin, including semaglutide and tirzepatide. Some are daily, and semaglutide is also available as a tablet, according to Cleveland Clinic.
Will I Start at My Full Dose?
Typically no. GLP-1 medications are started at a low dose and increased in steps. The FDA label for one semaglutide product starts at 0.25 mg weekly, and your clinician sets your own schedule.
When Might I Notice Appetite Changes?
Timing varies by person and medication. GLP-1 medications act on brain areas that control hunger and fullness, and your clinician will ask about your appetite at follow-ups to adjust your plan.
What Should I Ask at My First Follow-Up?
Ask how your dose will change, how to rotate injection sites, what to track, and when to check in again. Bring your log and questions so your clinician can tailor your plan.
Good to Know
Common side effects of GLP-1 medications are nausea, diarrhea, vomiting, constipation, and abdominal pain, most likely when you start or after a dose increase. Tell your clinician if you have a personal or family history of medullary thyroid cancer or MEN 2, pancreatitis, or kidney or eye problems, or if you are pregnant.
Plan Your Start With a Licensed Clinician
If you are curious about a GLP-1 medication, a licensed clinician can help you decide what fits. Complete an online assessment, have an independent licensed clinician review your health history, and, when a prescription is appropriate, receive your medication from a licensed pharmacy that delivers to your door.
