As weight management and diabetes control remain hot topics in the healthcare industry, two medications—semaglutide and tirzepatide—have taken center stage. Though they differ in several important ways, both medications have proven effective for weight loss. Healthcare providers now commonly use them to help treat patients with Type 2 diabetes.
Yet, few realize that semaglutide and tirzepatide are also great tools for Type 1 diabetes.
While these medications do not replace standard insulin treatment, they can support patients with Type 1 diabetes by:
- Improving blood sugar levels
- Lessening the reliance on insulin
- Reducing weight
But which medication is best for Type 1 diabetes? Let’s dive in!
What is Semaglutide?
Commonly known by brand names Ozempic, Wegovy, and Rybelsus, semaglutide is a GLP-1 receptor agonist. When injected, it mimics a naturally occurring hormone called glucagon-like peptide-1 (GLP-1) that stimulates insulin production.
Patients and physicians have had significant success using semaglutide to:
- Regulate appetite and calorie intake
- Reduce cravings
- Slow down digestion (making you feel fuller longer)
- Control your liver’s sugar production
- Lower blood sugar levels
- Support weight loss
What is Tirzepatide?
Newer to the market, tirzepatide (branded as Mounjaro and ZepBound) also mimics the GLP-1 hormone. But it also imitates another hormone called gastric inhibitory polypeptide (GIP), which makes it easier for your pancreas to release insulin and impacts how your body stores fat.
This dual-action approach offers all the benefits of semaglutide, but has shown even more effective for blood sugar control and weight loss.
Key Differences Between Semaglutide & Tirzepatide
How They Work
While both semaglutide and tirzepatide are injectable medications that fall into the GLP-1 receptor agonist drug class (meaning they mimic the GLP-1 hormone), tirzepatide is also a GIP receptor agonist. In effect, this additional hormone replication mechanism makes tirzepatide an extra powerful option for patients struggling with diabetes and obesity.
Glycemic Control
Studies have revealed that both medications help lower blood sugar and can reduce (or eliminate) insulin dependence. However, recent research suggests that tirzepatide is slightly more effective in improving Hemoglobin A1c (HbA1c), a critical blood sugar indicator for patients with diabetes.
Weight Loss
In a similar vein, researchers have found both semaglutide and tirzepatide effective for weight management. However, tirzepatide’s GIP-mimicking abilities are more pronounced, showing an average weight loss of 10% over the course of 9 months (as compared to 6% for semaglutide).
Cardiovascular Health
According to a study conducted by UC Irvine, both weight management medications also have the potential to dramatically decrease the risk for cardiovascular events (like heart attacks or strokes), with tirzepatide achieving a projected reducation rate of about 24% and semaglutide at about 20%. That being said, semaglutide may drive up your resting heart rate. More research is needed to get a complete picture of each drug’s impact on cardiovascular health.
Side Effects
Semaglutide and tirzepatide share many of the same potential side effects, including…
- Nausea & vomitting
- Constipation
- Diarrhea
- Abdominal discomfort
- Hypoglycemia (low blood sugar)
- And other gastrointestinal problems
Many of these symptoms occur during initial stages of treatment, as patients’ bodies get used to the medication.
In rare cases, users of both drugs may experience more severe side effects like:
- Pancreatitis
- Vision changes
- Kidney failure
- Gallbladder disease
- Renal Impairment
- Allergic reactions
Furthermore, while urinary tract infections (UTIs) are uniquely limited to the semaglutide side effect profile, several studies indicate that tirzepatide users more frequently report gastrointestinal issues, hypoglycemia, and other more serious side effects.
No matter which medication you choose, it’s essential for you to work closely with your healthcare provider to monitor any adverse reactions and adjust treatment accordingly.
Dosage
Both semaglutide and tirzepatide are administered via subcutaneous injections and may even be self-handled. But the dosage protocols differ significantly.
- Semaglutide is started at 0.25 mg weekly and is gradually increased up to 2.4 mg for peak effectiveness.
- Tirzepatide begins at a higher dosage of 2.5 mg per week and is slowly increased to a maximum of 15 mg, according to the patient’s response and tolerability.
Accessibility & Cost
Semaglutide has been on the market longer. Thus, it’s generally more accessible—and often cheaper—than tirzepatide. However, more and more healthcare clinics are choosing to stock both weight management medications to give their patients multiple options. It’s also important to note that while most insurance plans provide some coverage for these treatments, the extent of coverage differs on a case-by-case basis.
Semaglutide & Tirzepatide: Which is Better for Type 1 Diabetes?
Studies suggest tirzepatide may be slightly more effective for lowering blood sugar and reducing weight, two of the biggest challenges for patients with Type 1 diabetes. However, both medications show promising results for Type 1 diabetes patients. Ongoing research continues to reveal their potential impacts.
