❓ Frequently Asked Questions
Q: Is this the dose that helps with weight loss?
A: The 2.5 mg dose is primarily for tolerability. Weight loss effects increase with higher doses prescribed after the initial 4 weeks.
Q: Can I stay on 2.5 mg long-term?
A: No, this is a starter dose. Your doctor will typically increase it to 5 mg or more after 4 weeks.
Q: Will I feel side effects immediately?
A: Some users experience mild GI symptoms like nausea, but this dose is designed to minimize that risk.
Q: Can I inject it anywhere?
A: Inject into your abdomen, thigh, or upper arm, rotating the site each week for comfort and safety.
Q: Can Zepbound be prescribed for sleep apnea?
A: On December 20, 2024, FDA approved Zepbound (tirzepatide) for the treatment of obstructive sleep apnea in adults with obesity, to be used in combination with a reduced calorie diet and increased physical activity. This makes Zepbound the first drug treatment option for certain patients with sleep apnea.
Q: Are Zepbound and Mounjaro the same
A: Mounjaro and Zepbound are brand names for the same drug, tirzepatide. While Mounjaro is approved for type 2 diabetes, Zepbound is approved for weight management in adults with a BMI of 30 or more. It’s also approved if you’re overweight and have another health condition including: High blood pressure.
Q: Can you drink Alcohol while taking Zepbound?
A: While Zepbound (tirzepatide) doesn’t have any known direct interactions with alcohol, it’s generally not recommended to drink while taking it. Alcohol can worsen some of Zepbound’s side effects, like nausea, and may also interfere with weight loss efforts. If you choose to drink, it’s best to do so in moderation and after consulting with your doctor.
Q: Are Ozempic and Zepbound the same?
A: Zepbound is the weight loss version of tirzepatide, and Ozempic is the diabetes version of semaglutide. Some confusion exists about Ozempic’s purpose because it gained popularity when celebrities started using it “off-label” for weight loss rather than diabetes treatment. However, we’ll answer the question as asked.

The site worked, but it took some time to process my order. My Zepbound 2.5 mg pen came, but I didn’t get the confirmation email until much later.
Milna –
This is just the starter dose, so I haven’t noticed big changes yet. Some mild nausea, but nothing too bad. Hoping higher doses will show better results.
Danica –
The 2.5 mg pen is easy to use, but I didn’t see much progress at this dose. It feels more like a beginning stage than a treatment level.
