If you have a pacemaker or an implanted defibrillator (ICD), whether you can get a GLP-1 medicine depends on your full health history, and a licensed clinician makes that decision. The most useful thing you can do is tell them about the device, the heart condition it treats, and every medicine you take.
This guide covers what to share, why your cardiologist matters here, and how to plan for common side effects. It is general information, not medical advice for your situation.
What is a pacemaker or ICD?
A pacemaker is a small implanted device that helps keep your heartbeat from going too slow or becoming irregular. An ICD is a similar device that can also deliver a shock to correct a dangerous heart rhythm. Some people have a device that does both. The device is there because of an underlying heart condition, and that condition is a big part of what a clinician wants to understand.
What should I tell the clinician?
Be as complete as you can. Include:
- What kind of device you have and when it was placed
- The heart condition behind it, such as a slow heart rate, a rhythm problem, or heart failure
- Who treats you, such as a cardiologist or a heart rhythm specialist, and when you last had a device check
- Any recent shocks, symptoms, hospital stays, or changes to your treatment
- Every heart medicine you take, plus all other prescriptions, over-the-counter medicines and supplements
- Whether you take insulin or a sulfonylurea, because the brand-name labeling notes low blood sugar is mainly a concern with those
- Any kidney problems, and any history of pancreatitis, gallbladder problems, or thyroid cancer in you or your family
Also say if you are pregnant, breastfeeding or trying to conceive, since GLP-1 medicines are not a fit then.
Who answers questions about the device itself?
Your cardiologist or the team that manages your device. They know your heart, your device settings and your history. A clinician reviewing your GLP-1 assessment may ask for recent notes or suggest you talk with your cardiologist before starting. That is not a rejection. It is a way to decide with the right information.
It helps to raise GLP-1 medicine with your cardiologist yourself. Let them know you are considering it and ask how they want you to handle it if you get sick or feel dizzy.
Why do dehydration and dizziness matter?
GLP-1 medicines act on appetite and fullness and slow how fast your stomach empties. You can read more in how GLP-1 medicines act in the body. The FDA labeling for brand-name semaglutide and tirzepatide lists nausea, vomiting, diarrhea, constipation and stomach pain as common side effects, and notes that dehydration from vomiting or diarrhea can lead to kidney problems.
Dehydration can also leave you dizzy or lightheaded. If you live with a heart condition and take heart medicines, that is worth flagging to both your GLP-1 clinician and your cardiologist ahead of time, so you know how to stay hydrated and when to call.
Who makes the final call?
A licensed clinician in the Beluga Health network reviews your assessment and decides. They may approve treatment, ask for more information, or decline. Basic eligibility still applies: adults 18 to 80, and a BMI of 25 or higher if you are new to GLP-1 medicines. Read more in who is eligible for GLP-1 treatment, or see who can prescribe compounded GLP-1.

What if I start and have side effects?
If you are a VevaMD member, message your clinician from your My VevaMD page about any new or worsening symptoms, and tell your cardiologist too. Do not skip or change a dose on your own. Call 911 for chest pain, fainting, a racing or pounding heartbeat, trouble breathing, severe stomach pain that won't go away, signs of a serious allergic reaction, or signs of severe dehydration. See what to do about GLP-1 side effects for more warning signs.
