Zepbound is a prescription medication that works as both a GIP and GLP-1 receptor agonist. This medication is prescribed to patients with obesity (BMI of at least 30 kg/m²) to help them lose weight. It is also sometimes used for those who are overweight (BMI of at least 27 kg/m²) and have been diagnosed with a weight-related condition. Zepbound has also been approved for use in treating patients with obesity who struggle with moderate to severe OSA. This medication comes in a couple of different injectable forms and is taken weekly by the patient.
There are several different strengths and doses available for Zepbound users. Single-dose pen and vial versions of Zepbound can be found in the following strengths:
Each of the multi-dose vials or single-patient-use KwikPens has four doses of the medication within them. These devices are offered in the following strengths:
Patients using the KwikPen version of Zepbound can do so by:
Those using the single-patient-use pens will have to follow a different set of instructions.
The vial versions also use a separate set of instructions.
All needles and devices used to administer Zepbound should be properly disposed of after use.
Zepbound has a boxed warning for the potential cause of C-cell tumors – including medullary thyroid carcinoma (as experienced in some rodent studies). The human relevance of these findings is still undetermined. This treatment is not recommended for patients with a personal or family history of MTC. It is also contraindicated in those who have been diagnosed with Multiple Endocrine Neoplasia type 2. Patients should also refrain from taking this medication if they have a known serious hypersensitivity to the medication or any of its ingredients.
This medication may also cause serious gastrointestinal problems in some patients. Use of this medication is not advised for patients with severe gastroparesis. Renal function should also be monitored for patients using this medication since it may lead to kidney injury in some rare cases. Gallbladder issues have been reported in some instances for patients using this medication in clinical trials. Further testing is recommended if any indications of cholecystitis appear.
Cases of acute pancreatitis have occurred in patients taking GLP-1 medications. Patients should stop Zepbound if there are signs of pancreatitis. Serious hypersensitivity reactions have also occurred in some cases during postmarketing use of tirzepatide. Patients with these issues should seek immediate medical attention and stop taking the medication.
Risk of hypoglycemia increases when this medication is used with insulin or insulin-stimulating medications (it is uncommon when used alone). Dose adjustments may be required. Patients with a history of diabetic retinopathy should be monitored for worsening symptoms. These issues are more common for patients with type 2 diabetes. There have been rare reports of pulmonary aspiration while using Zepbound around the time of general anesthesia or deep sedation. Patients should let their healthcare team know before having surgery. Pens and devices should never be shared between patients – even if the needle is changed.
The most commonly experienced side effects for patients taking Zepbound include:
Studies show that side effects like nausea/vomiting and diarrhea usually occur during dose increases and typically decrease on their own over time. Patients with persistent or severe side effects should talk to their doctor.
This medication can also lead to severe side effects in some less common cases. This includes side effects such as severe stomach problems or stomach problems that do not go away. It may also include severe side effects such as kidney problems. However, these issues usually occur as a result of dehydration from loss of fluids and staying hydrated can help reduce the likelihood of developing these issues.
Patients who miss a dose of this medication should take the missed dose as soon as possible as long as it is still within four days of when it was originally scheduled to be taken. Patients should skip their missed dose if it has been longer than those four days and resume their regular dosing schedule as normal at the next scheduled time. A maximum of 15 mg of this medication can be taken per week. Patients who overdose on this medication should contact the Poison Help Line (by calling 1-800-222-1222) or a medical toxicologist. This line is specific to patients located in the U.S.
Single-dose pens – as well as single-dose vials – variations of Zepbound should be kept in a refrigerated environment at a temperature of 36°F to 46°F – equivalent to storing between 2°C and 8°C. This medication may be kept at room temperature up to 86°F (the equivalent of 30°C) for up to 21 days before it should be discarded (do not place back in the refrigerator after doing so).
Multi-dose vials and single-patient-use KwikPens may be stored in the refrigerator or at room temperature. Discard after 30 days at room temperature/30 days after first use or after 4 weekly doses – whichever comes first. Keep this medication out of conditions where it may become frozen or exposed to direct sunlight.

A Zepbound injection is done under the skin of the stomach or thigh. It can also be administered into the upper arm.
There is a possibility that you will experience side effects after your first shot. It is common for patients to experience nausea, diarrhea/vomiting or constipation.

Zepbound has been approved for use in chronic weight management treatment by the FDA on November 8th, 2023.
After you start taking Zepbound, it takes a few weeks before you begin to notice changes in your appetite and sometimes a few weeks more before you start losing weight. The medication begins working on a cellular level relatively quickly.
It is possible to develop serious side effects from Zepbound, including kidney failure (kidney damage).
This is a common side effect of taking Zepbound in some clinical studies. Zepbound caused hair loss in 4% to 5% of users, while a placebo caused hair loss in 1% of users.
Some people may experience depression or suicidal thoughts when taking Zepbound. In the event of depression or suicidal thoughts, a physician should be contacted immediately.
As with any injection, a small amount of blood may arise from the injection site. If there is more than a small amount, cover up the wound and proceed to the nearest health facility.
Dispose of the used pen right after use in a sharps container cleared by the FDA. Household garbage should not be used.
