Tirzepatide vs Semaglutide Side Effects

If you’re considering tirzepatide or semaglutide for weight loss or diabetes management, you’re probably wondering about their side effects.

These medications work in similar ways, helping regulate blood sugar and control appetite, but they also come with potential downsides.

In this guide, we’ll break down the tirzepatide vs semaglutide side effects, how they compare, and what you can do to manage them.

We’ll also explain how Eternity Health Partners can help you get the most out of your treatment.

 

LOSE WEIGHT WITH TIRZEPATIDE OR SEMAGLUTIDE

 

What Are Tirzepatide and Semaglutide?

 

Let’s take a look at these two weight loss medications are:

 

Tirzepatide

 

Tirzepatide is a dual GIP/GLP-1 receptor agonist, meaning it mimics two natural hormones that help regulate blood sugar and appetite.

It’s FDA-approved for type 2 diabetes and is also being used for weight loss.

 

Semaglutide

 

Semaglutide is a GLP-1 receptor agonist, meaning it works by slowing digestion, reducing hunger, and improving blood sugar control.

It’s FDA-approved for type 2 diabetes (Ozempic®) and weight management (Wegovy®).

FAQs:  Tirzepatide vs Semaglutide

 

What are the side effects of tirzepatide vs retatrutide?

Tirzepatide and retatrutide both belong to the class of medications that help with blood sugar control and weight loss, but they have different mechanisms of action. Tirzepatide is a dual GIP/GLP-1 receptor agonist, while retatrutide is a triple GIP/GLP-1/Glucagon receptor agonist. Both medications share common side effects like nausea, vomiting, diarrhea, and constipation, but early research suggests that retatrutide may have a slightly higher likelihood of gastrointestinal discomfort and increased heart rate due to its additional glucagon activation. More clinical trials are needed to fully compare long-term safety and tolerability.

What are the side effects of semaglutide vs retatrutide?

Semaglutide and retatrutide both function as GLP-1 receptor agonists, but retatrutide also activates the GIP and glucagon receptors, which may lead to more weight loss but potentially more side effects. The most common side effects for both include nausea, vomiting, diarrhea, and constipation, though retatrutide may cause more elevated heart rate and transient increases in blood pressure due to glucagon activity. Since retatrutide is newer and still being studied, long-term data on side effect differences is limited.

What is the best weight loss injection?

The best weight loss injection depends on individual health goals, tolerance for side effects, and medical history. Tirzepatide (Mounjaro®) and retatrutide have shown the most significant weight loss results in clinical trials, with tirzepatide leading to an average weight loss of up to 21% and retatrutide potentially exceeding that. Semaglutide (Wegovy®) also delivers substantial weight loss, with an average of around 15%. If tolerability is a concern, semaglutide may be a safer choice due to more established safety data. Consulting with a healthcare provider is the best way to determine which medication is right for you.

Does tirzepatide have fewer side effects than Ozempic?

Tirzepatide and Ozempic (semaglutide) have similar side effect profiles, with nausea, diarrhea, vomiting, and constipation being the most common. Some clinical trials suggest that tirzepatide may cause less severe nausea over time compared to semaglutide, though it may initially lead to slightly more gastrointestinal distress in the first few weeks of treatment. Both medications carry risks of more serious side effects like pancreatitis, gallbladder issues, and thyroid tumors (in animal studies). Individual responses vary, and some people tolerate tirzepatide better than Ozempic, while others find the opposite to be true.

Do you lose more muscle on semaglutide or tirzepatide?

Weight loss injections like semaglutide and tirzepatide can lead to both fat and muscle loss, but studies suggest that tirzepatide may help preserve more muscle mass than semaglutide due to its dual GIP/GLP-1 action. GIP activation may promote better fat loss while maintaining lean muscle, making tirzepatide a better option for those concerned about muscle preservation. Regardless of which medication is used, resistance training and adequate protein intake can help reduce muscle loss during weight loss.

Can I switch from Ozempic to tirzepatide?

Yes, many people switch from Ozempic (semaglutide) to tirzepatide (Mounjaro®), especially if they are not achieving their desired weight loss results or if they experience side effects that are difficult to manage. Since both medications are weekly injections, the transition is generally smooth, but dose adjustments may be needed to avoid excessive nausea or digestive issues. It’s important to consult with a healthcare provider before switching to ensure a safe and effective transition.

MEET ELIZABETH BECKNER AND DAISHA ESCAMILLA

OUR CALIFORNIA LICENSED PHLEBOTOMISTS

Liz started doing personal blood draws after her son, Dashiell, was born with Zellwegers disease. His diagnosis required numerous blood draws and drug levels throughout his life. After sitting through long wait times at the labs followed by watching many different phlebotomists, many new to the job, struggle to find his veins, often poking him multiple times, as a seasoned phlebotomist, Liz decided to draw his blood at home and hand deliver it to the lab myself. Soon after she began doing personal touch blood draws so she can now offer that same personalized service to you.

Liz graduated from Pepperdine University with a degree in Biology in 1994. She moved to Santa Barbara and earned her phlebotomy certificate in 1995. Liz began working at St. Francis Medical Center in the Physical Therapy Department and quickly transferred to the Laboratory. Perfecting her venipuncture techniques on all floors of the hospital, including post-operative patients, pregnant women going into labor, sick or premature babies, and emergency room patrons, she then improved her patient care skills working for internal medicine doctors, one of whom was the Medical Director of Hospice and won Doctor of the Year. In 1999, Liz started working with a group of local retinal surgeons. Her primary job consisted of injecting dye into arm veins and photographing its flow through the patients retinal vessels. When patients are worried about their diagnosis or apprehensive about the procedure because of difficult veins, her quick, almost pain free needle stick and kind but professional bed side manner would put them at ease.

The various settings and patients Liz has encountered over the years have enabled her to become very skilled at finding the smallest and most fragile of vessels. Her specialities include infants and the elderly, diabetics of all ages, patients with rolling veins, on blood thinners or chemotherapy. She lives in downtown Santa Barbara, travels from Goleta to Carpintera and brings all the necessary supplies directly to you. All she needs from you is a lab request and your home or office becomes an instant draw station. Appointment times are very flexible, and she is friendly, reliable and punctual. Be kind to your arm and treat yourself to the luxury blood draw you deserve!!!

MEET MICHAEL BROOKINS; BS, CNMT, ABAAHP

Mike brings more than just a medical perspective to his clients; at the age of 14, he began an athletic career as a pole-vaulter that would end up taking him on an incredible journey over the next 13 years of his life. Throughout his athletic journey Mike was constantly working to find the ideal balance of fitness and proper nutrition in order to maximize his performances. Combined with his medical knowledge the years of athletic experience provide a unique and successful combination that serve to benefit his staff and clients.

“After I shifted the focus of my practice from Sports Medicine into Nuclear Medicine specifically Interventional Endocrinology. I found myself questioning our western medical paradigm…Here I was performing thyroid cancer and Hyperthyroidism treatments with harmful radical thyroid radioactive ablations which really made me take a hard look in the mirror and become more of a researcher to find safer and more effective options to better treat my clients. During my research I realized that there were very few, if any, medically directed programs focused towards achieving a “Healthier Lifestyle” rather than typical “Diet” fads.” A few years later after training and working with some of the worlds foremost Bio-identical Hormone Replacement specialists I became Board Certified in Anti-Aging and Regenerative Medicine. Sort of just found my passion and the answers I had been looking for with this new specialty finally after years of treating people with the Band-Aid “fix it when its broken” mentality instead of at the root cause.”

Mike has spent the last 10 years in Anti-Aging, Functional and Regenerative Medicine. He has trained over 120 physicians in Anti-Aging and Regenerative Medicine and consulting for their practices. Today his vision is a reality, and clients from all of the world come to benefit from the successful programs that have been established at Age Management Institute Santa Barbara. He firmly believes in educating the patient about the importance of good nutrition, hormone balance, stress management, and regular exercise is the key to aging well and having a high quality of life well into your golden years.
