What Your Prescriber Considers When Heart Failure Is Part of Your History
Heart failure covers a wide spectrum of severity and type, which is one reason there is no single universal answer to whether weight loss injections are appropriate. Your prescriber will weigh up factors including the class and stability of your heart failure, any other medicines you take, and whether the potential benefits of treatment outweigh the risks in your individual case.
What the medicines are
Mounjaro (tirzepatide) is a dual GIP and GLP-1 receptor agonist, and Wegovy (semaglutide) is a GLP-1 receptor agonist. Both are prescription-only, once-weekly injectables. Neither is insulin, and neither is suitable for everyone — suitability is always determined by a qualified prescriber based on your full medical picture.
Heart failure and GLP-1 medicines: an evolving picture
Research into GLP-1 receptor agonists and cardiac outcomes is ongoing, and findings differ depending on the type of heart failure involved. Because this is a clinically complex area, it is especially important not to draw conclusions from general information alone. Your prescriber or cardiologist will be aware of the current evidence and can apply it to your situation specifically. If you have any concerns about whether your prescription is appropriate given your heart history, raise them at your next appointment — or sooner if anything changes.
Other health conditions can also affect suitability for these medicines. You may find it useful to read about considerations around weight loss injections and gallstones or weight loss injections with an underactive thyroid, as these are similarly nuanced topics where individual assessment matters.
For broader context on how these medicines work and who they are prescribed to, the weight loss injections overview covers the essentials.

How GLP Trackr Supports You If You Are Already Prescribed
If your prescriber has determined that a weight loss injection is appropriate for you despite a heart condition, staying consistent and keeping a clear record of how you feel becomes even more important. GLP Trackr's side-effect and symptom tracking is particularly useful here — you can log how you feel day to day, note any changes in energy, breathlessness, or other symptoms, and build a clear picture to bring to your next appointment.
The app also logs each injection, including dose strength, date, and site, so your prescriber always has an accurate record of your treatment timeline. If anything feels off between appointments, that logged history can make your conversation with your healthcare team much more productive than trying to recall details from memory.
GLP Trackr is a tracking and journaling companion — it is not a medical service and does not replace your prescriber's guidance. Any concerns about your heart condition and your medication should always go straight to your healthcare professional. If you experience symptoms that feel new or worrying — such as increased breathlessness, swelling, or chest discomfort — contact your healthcare professional promptly rather than waiting.

Frequently asked questions.
Whether Mounjaro or Wegovy is appropriate with heart failure depends on your individual cardiac history, medication, and overall health. This is a clinical decision for your prescriber or cardiologist — there is no single answer that applies to everyone.
Heart failure does not automatically rule out GLP-1 medicines, but it is a significant factor your prescriber will carefully evaluate. The type and severity of heart failure, along with your other medications, all influence suitability. Always discuss this with your healthcare professional.
Yes — always share your full medical history, including any heart condition, with your prescriber before starting any new medicine. They need this information to assess whether treatment is safe and appropriate for you.
GLP Trackr lets you log symptoms, side effects, and how you feel each day, creating a record you can share with your prescriber or cardiologist. It tracks doses and injection sites but does not provide medical advice or replace clinical guidance.
If you experience new or worsening symptoms — especially anything affecting your heart or breathing — contact your healthcare professional promptly. Log what you notice in GLP Trackr so you have an accurate record to discuss, but do not wait if symptoms feel urgent.
