What Makes Mounjaro Different:
Unlike Ozempic and Wegovy which target only GLP-1 receptors, Mounjaro is a dual-action medication that activates BOTH:
- GIP (glucose-dependent insulinotropic polypeptide) receptors
- GLP-1 (glucagon-like peptide-1) receptors
This dual mechanism delivers superior weight loss compared to single-action GLP-1 medications.
How Does Tirzepatide Injection Work?
GLP-1 Pathway (Shared with Ozempic/Wegovy):
- Reduces appetite
- Slows gastric emptying
- Improves insulin secretion
- Reduces glucagon (less sugar release)
GIP Pathway (Unique to Mounjaro):
- Enhances insulin sensitivity
- Improves fat metabolism
- Reduces fat storage
- Boosts energy expenditure
- Synergizes with GLP-1 effects
The Combined Effect:
System
- Brain (Hypothalamus)
- Stomach
- Pancreas
- Fat Tissue
- Liver
- Metabolism
What Happens
- Hunger signals reduced
- Hunger signals reduced
- Emptying slows down
- Glucagon reduced
- Insulin secretion improved
- Visceral fat targeted
Result
- Stronger appetite suppression
- Prolonged fullness
- Better blood sugar control
- Greater fat loss
- Fatty liver improvement
- Higher calorie burn
The Science Behind Mounjaro's Dual Action:
- Think of it like this: GLP-1 alone is effective, but GIP amplifies and extends those benefits. Clinical trials show tirzepatide injection achieves approximately 5-7% more weight loss than semaglutide at comparable doses.

The "Off-Label" Question:
When doctors prescribe Ozempic for weight loss in non-diabetic patients, this is “off-label” use. This is:
- Legal and common practice
- Based on strong clinical evidence
- Requires proper medical supervision
- Effective for weight management
Your DermaVue doctor will determine which formulation and dose suits your specific needs.
When Mounjaro May Be Preferred:
- Significant insulin resistance
- Type 2 diabetes requiring aggressive treatment
- Prior incomplete response to GLP-1 alone
- Fatty liver disease (NAFLD/NASH)
- Multiple metabolic comorbidities
When Ozempic/Wegovy May Be Preferred:
- Lower BMI requiring moderate weight loss
- Well-controlled or no diabetes
- Budget considerations
- Preference for established longer-term safety data
- Mounjaro not available or accessible

Frequently Asked Questions
What is Mounjaro and how is it different from Ozempic?
Mounjaro (tirzepatide) is a dual GIP/GLP-1 receptor agonist, while Ozempic (semaglutide) targets only GLP-1 receptors. This dual mechanism gives Mounjaro superior weight loss efficacy – approximately 20-22% versus 15-17% for Ozempic in clinical trials. Mounjaro also shows greater improvements in blood sugar control and metabolic markers.
How much weight can I lose on Mounjaro?
Clinical trials show average weight loss of 20-22% of body weight on the maximum 15mg dose over 72 weeks. For a 90kg person, this translates to approximately 18-20kg. Some patients lose more than 25% of their body weight. Individual results depend on starting weight, dose achieved, diet, exercise, and metabolic factors.
How is Mounjaro injection given?
Mounjaro is a once-weekly subcutaneous injection using a pre-filled pen. You inject it yourself at home after training. Injection sites include abdomen, thigh, or upper arm. The process takes about 30 seconds. Our team provides thorough injection training at your first visit.
What are the main side effects of Mounjaro?
The most common side effects are gastrointestinal: nausea (25-35%), diarrhea (15-25%), and decreased appetite. These typically occur during the first few weeks and with dose increases, then improve. Serious side effects are rare but include pancreatitis and gallbladder problems. Gradual dose titration significantly reduces side effect severity.
Is Mounjaro safe for non-diabetics?
Yes, when properly prescribed and supervised. Tirzepatide (as Zepbound) is FDA-approved specifically for chronic weight management in non-diabetic patients with obesity or overweight with comorbidities. Mounjaro used for weight loss in non-diabetics is “off-label” but supported by strong clinical evidence.
How long before I see results with Mounjaro?
Most patients notice reduced appetite within 1-2 weeks. Measurable weight loss typically begins by week 4. Significant visible changes occur by month 2-3. Maximum results are usually achieved around month 12-18. The medication works progressively, which is healthier than rapid weight loss.
Can I take Mounjaro if I have diabetes?
Yes – Mounjaro was originally approved for Type 2 diabetes and provides excellent blood sugar control alongside weight loss. In fact, it may be particularly suitable for diabetics requiring both glucose management and significant weight loss. If you’re on insulin or sulfonylureas, your doctor will adjust those medications to prevent hypoglycemia.
Is Mounjaro available in India?
Yes, Mounjaro (tirzepatide) is available in India with a valid prescription. However, supply can be limited due to global demand. Never purchase from unverified sources – counterfeit medications are a serious risk. DermaVue sources medications through verified pharmaceutical channels.
What happens when I stop taking Mounjaro?
Studies indicate some weight regain occurs after stopping tirzepatide, similar to other weight loss medications. This is why our program emphasizes lifestyle integration and metabolic flexibility training. Some patients may benefit from long-term therapy, while others can successfully maintain results with lifestyle modification after stopping.
How does the cost of Mounjaro compare to Ozempic?
Mounjaro is generally more expensive than Ozempic due to its newer status and higher efficacy. However, the cost per percentage of weight loss may be comparable given Mounjaro’s superior results. DermaVue provides transparent pricing and can discuss cost considerations during your consultation.
