How do you track side effects on a GLP-1?
Keep GLP-1 dose records, symptoms, appetite and everyday impact together so you can describe your experience clearly to your prescribing clinician.

The short answer
What should a GLP-1 symptom log contain?
Record the prescribed product, actual dose event and time, then note symptoms in plain language: when they began, how long they lasted and what they interrupted. Add relevant food, fluid and routine context without assigning a cause. Use the record for conversations with your clinician, not to choose or change a dose.
How you felt on an ordinary afternoon can be difficult to reconstruct at an appointment several weeks later. Was eating uncomfortable? Did you stop halfway through a usual activity? Did that happen once, or are you remembering the hardest day more clearly than the others?
A GLP-1 tracking routine can hold those details while they are still fresh. The goal is a clearer account of your experience. It is not a score for tolerating symptoms, and it does not ask you to keep collecting data when you need help.
Which medication details should come first?
Save the exact product and the instructions you received. Record what you actually took with its date, time and unit. Where relevant, keep the injection site and the original pharmacy information. A scheduled entry and a recorded event should remain different: the plan alone does not show what happened.
Do not guess a conversion from a number on a syringe or another person’s screenshot. The FDA has reported dosing errors involving compounded semaglutide, including confusion between units and concentrations. If the instructions are unclear, contact the dispensing pharmacist or prescriber before using the product.
How can you describe a symptom usefully?
| Detail | Question to answer | Example wording |
|---|---|---|
| Onset | When did you first notice it? | Started after lunch on Tuesday |
| Duration | How long did it last? | Still present at bedtime |
| Intensity | How did it compare with your usual experience? | More uncomfortable than yesterday |
| Practical impact | What did it interrupt? | Could not finish my usual meal |
| Other context | What else changed? | Travel day and a different meal schedule |
These are example phrases, not expected effects or thresholds for seeking care. Use your own words. If your clinician has asked you to record a specific symptom or measure, follow that instruction and keep the wording consistent. A new description can be more valuable than another number on a scale.
Where do food, fluids and energy fit into the record?
Record the context that helps you remember the day: meal timing, what you were able to eat or drink, energy and any interrupted activity. Keep descriptions neutral. “Lunch was smaller than usual” records an observation. It does not make the day a success or failure.
A food photo or a brief note may be enough for the question you are bringing to your appointment. You do not have to reconstruct exact nutrients when you do not know them. If food tracking becomes burdensome, ask your clinician what information is most useful and reduce the record to that.
Weight is one possible record, not a substitute for how you feel. If you choose to record it, preserve the date and usual measurement context. A change in a chart does not explain a symptom, and a symptom should not be dismissed because another number moved in a desired direction.
What should you look for between appointments?
Build a short chronology. Mark actual dose events, then identify when symptoms were first recorded and whether they recurred. Include days when you recorded no symptom, and distinguish those from days you did not check in. That makes the account more complete without turning it into a treatment judgment.
For example, an invented week might show an injection entry on one day, a discomfort note the next afternoon and two later days with no check-in. You can say when the discomfort was logged. You cannot say it lasted only one day, or that the injection caused it, from those entries alone.
The NIDDK overview of prescription weight-management medicines notes that side effects vary by medicine and that treatment decisions belong with a health professional. Your record adds the particular details of your experience to that conversation.
When should you stop logging and contact someone?
Follow the urgent-action instructions supplied with your medicine. If a symptom is severe, persistent, worsening or concerning, seek medical advice promptly; use emergency care for an emergency. Do not wait for a pattern, a scheduled review or an app response before acting on an urgent concern.
You do not need to diagnose a reaction before contacting your clinician. Describe what happened, when it started, the product you took and what you can or cannot do. If you suspect an incorrect dose, say that clearly. The record supports the call; it does not decide whether the call is justified.
What does Moodwell’s GLP-1 tracker help you keep?
The GLP-1 tracker brings recorded injections, sites, symptoms, notes and weight history near your existing schedule and supply information. You can also keep meals in Nutrition and workouts in Fitness. Those are records in one application, not evidence that one layer explains another.
- Confirm the product information and prescribed schedule.
- Log the actual event with the information you know.
- Add observations while you can describe them clearly.
- Review the chronology and unresolved questions before your appointment.
If you already have eligible history in Shotsy, Moodwell supports a Shotsy file import. Review the imported results and dates. An import can preserve earlier records; it cannot fill in symptoms you never logged.
Follow the evidence

Questions, answered
Can tracking tell me whether my dose should change?
No. Dose and treatment decisions belong with your prescribing clinician. A log can help you describe your experience, but neither a symptom trend nor an estimated-level chart supplies a personalized dosing decision.
Should I call every symptom a side effect?
You can record a symptom without deciding its cause. Note the timing and circumstances, then discuss possible links with your clinician. A symptom that follows a dose event is not automatically established as a drug reaction.
Do I need a wearable or food scale?
No. Plain-language observations and accurate medication-event records can be useful. Use the measurement detail you actually have, and ask your clinician which additional records would help your care.
Does a modeled level show how much medicine is in my body?
It is an estimate based on a model and the entered history, not a laboratory measurement. Individual circumstances and incorrect or missing inputs can limit it. Do not use it to decide when or how much medication to take.
