What is Zepbound?
Zepbound is a prescription injection designed to assist with long-term weight loss and manage weight-related health conditions. Approved by the FDA for adults categorized as obese or overweight, Zepbound is particularly beneficial for individuals facing health issues such as sleep apnea, high blood pressure, or type 2 diabetes.
The active ingredient in Zepbound is tirzepatide, which works by reducing appetite, controlling hunger, and enhancing sensations of fullness after meals. This mechanism encourages users to consume less food, leading to greater weight loss over time.
Administered once a week via an injectable method under the skin, Zepbound is most effective when accompanied by a balanced diet and regular physical activity. Clinical studies have demonstrated that participants using Zepbound experienced significant weight loss compared to those on a placebo. Additionally, it has shown promising outcomes for individuals with obstructive sleep apnea by alleviating symptoms and aiding in weight management. Overall, Zepbound presents a compelling option for those seeking to achieve their weight loss goals or effectively manage related health conditions.
How Does Zepbound Work?
Zepbound operates by mimicking a natural hormone known as GLP-1, which plays a crucial role in the regulation of hunger, insulin production, and digestion. When administered regularly, it interacts with the brain’s appetite control centre, leading to reduced cravings and a prolonged sensation of fullness. This results in lower calorie consumption without the need for drastic dieting. Additionally, Zepbound enhances insulin sensitivity, facilitating improved control over blood sugar levels. Together with a healthy lifestyle, Zepbound can contribute to steady weight loss over time, acting as a supportive tool that aligns with the body’s natural processes.
Comparing Zepbound and Mounjaro
While Zepbound and Mounjaro share similarities, they are designed for different purposes. Both medications contain the active ingredient tirzepatide; however, Zepbound is FDA-approved explicitly for weight loss, whereas Mounjaro is primarily intended for managing type 2 diabetes. Both drugs target hormones related to hunger, but Zepbound is tailored for individuals aiming to lose weight, regardless of whether they have diabetes. At the same time, Mounjaro focuses on improving blood sugar control.
Side Effects of Zepbound
Common Side Effects
Users of Zepbound may experience several common side effects, including
Nausea: A common initial reaction that typically diminishes over time.
Vomiting: Some individuals may experience vomiting in the early weeks of treatment; remaining hydrated and opting for light meals can help.
Diarrhea: Loose stools may occur but often lessen as the body adapts.
Constipation: Difficulty with bowel movements may arise, especially if fluid intake is inadequate.
Stomach Discomfort: Mild pain, bloating, or cramping may occur, particularly at the beginning of treatment.
Loss of Appetite: A decreased desire to eat is normal and contributes to weight loss.
Fatigue: Some users may initially feel tired or low in energy, though this often improves with consistent use.
Serious Side Effects
Although rare, Zepbound can trigger serious side effects that necessitate immediate medical attention. These include:
Pancreatitis: Pancreatitis is characterized by severe upper stomach pain that may radiate to the back, often accompanied by vomiting.
Gallbladder Issues: Symptoms such as intense abdominal pain, fever, or jaundice may indicate gallbladder problems.
Kidney Concerns: Dehydration caused by vomiting or diarrhea can impact kidney function, leading to reduced urine output or swelling.
Thyroid Tumors: While extremely uncommon, some research indicates a potential link between Zepbound and thyroid C-cell tumors.
Severe Allergic Reactions: Symptoms like swelling, rash, breathing difficulties, or itching should be taken seriously, as they may indicate an allergy.
Hypoglycemia in Diabetics: When taken alongside other glucose-lowering medications, Zepbound may cause dangerously low blood sugar levels.

How should I use Zepbound?
Zepbound is a weekly injection. It is injected under the skin in your thigh, belly, or upper arm. Always follow your doctor’s advice when using it. Try to use it on the same day each week. You can change the day if necessary, but make sure there are three days between doses.
If you miss a dose, take it within four days. If more than four days have passed, skip the dose. Never take two doses at once, and do not share your injection pen with anyone. Change the injection site each time to avoid irritation.
Comparing Zepbound and Wegovy: Insights from the SURMOUNT-5 Clinical Trial
The SURMOUNT-5 trial provided essential findings regarding the effectiveness of Zepbound in comparison to Wegovy. While both medications are designed to assist with weight loss, they function differently within the body. Zepbound contains a tripeptide that targets two hormones responsible for hunger regulation—GLP-1 and GIP—whereas Wegovy primarily focuses on GLP-1 alone. Results from clinical trials have shown that Zepbound leads to greater weight loss than Wegovy, suggesting it may be a more effective option for those who have not found success with other treatments.
Key Findings SURMOUNT-5:
Average Weight Loss:
- Zepbound: 50.3 pounds (22.8 kg)
- Wegovy: 33.1 pounds (15.0 kg)
Body Weight Reduction (%):
- Zepbound: 20.2%
- Wegovy: 13.7%
- Zepbound resulted in 47% more weight loss compared to Wegovy.
Weight Loss Achieved:
- Zepbound: 64.6%
- Wegovy: 40.1%
Average Waist Size Reduction:
- Zepbound: 7.2 inches (18.4 cm)
- Wegovy: 5.1 inches (13.0 cm)
Before using this medicine
It is crucial to refrain from using Zepbound if you:
- Have allergies to tirzepatide or any components of the medication.

Pregnancy
Suppose you are pregnant, planning to become pregnant, or find out you are pregnant while taking Zepbound. In that case, it is vital to contact your healthcare provider immediately, as the safety of this medication during pregnancy has not been clearly established. A registry exists to monitor the health of pregnant women using Zepbound and their babies; your doctor can provide further details about participation in this study.
Additionally, Zepbound may decrease the effectiveness of birth control pills. Your healthcare provider may recommend alternative contraceptive methods, such as injections, implants, patches, vaginal rings, or barrier methods. If you rely on birth control pills, it is advisable to use additional contraceptive measures for four weeks after starting Zepbound or following any dosage increase.
Breastfeeding
If you are currently breastfeeding or intend to breastfeed while using Zepbound, it is essential to consult with your healthcare provider. The potential for the medication to pass into breast milk and its effects on your baby are not yet understood. Your healthcare professional can assist in determining the safest approach for breastfeeding during your treatment.
