How Long Do Zepbound Side Effects Last?

For most people:

• Nausea and digestive issues are most noticeable during the first few weeks.
• Symptoms may temporarily worsen after a dose increase.
• Many side effects improve as your body adjusts.

Your prescribing provider will usually start you on a lower dose and gradually increase it. This "dose escalation" helps reduce side effects.

If symptoms are persistent, severe, or worsening, speak with your healthcare provider.

Serious Zepbound Side Effects: What to Watch For

Although less common, there are important safety warnings associated with Zepbound.

1. Thyroid C-Cell Tumors (Boxed Warning)

Zepbound carries an FDA boxed warning about a possible risk of thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), based on animal studies. It's not known if this risk applies to humans.

Do not use Zepbound if you:

• Have a personal or family history of medullary thyroid carcinoma (MTC)
• Have Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)

Call your doctor right away if you notice:

• A lump or swelling in your neck
• Hoarseness
• Trouble swallowing
• Shortness of breath

These symptoms are rare but require immediate medical attention.

2. Pancreatitis

Inflammation of the pancreas (pancreatitis) has been reported with GLP-1–based medications.

Seek urgent medical care if you develop:

• Severe, persistent abdominal pain (especially radiating to the back)
• Pain that does not go away
• Vomiting along with severe stomach pain

Pancreatitis can be serious and requires prompt evaluation.

3. Gallbladder Problems

Rapid weight loss itself can increase the risk of gallstones. Zepbound may also increase the risk of gallbladder disease.

Symptoms include:

• Upper right abdominal pain
• Fever
• Yellowing of the skin or eyes (jaundice)
• Clay-colored stools

Contact your healthcare provider if you experience these symptoms.

4. Low Blood Sugar (Hypoglycemia)

Zepbound alone does not usually cause low blood sugar. However, risk increases if you:

• Have type 2 diabetes
• Take insulin
• Use sulfonylurea medications

Symptoms of low blood sugar include:

• Shakiness
• Sweating
• Confusion
• Dizziness
• Fast heartbeat

Your provider may need to adjust other diabetes medications.

5. Kidney Problems

Severe vomiting or diarrhea can lead to dehydration, which may worsen kidney function.

Stay hydrated and contact your doctor if you:

• Cannot keep fluids down
• Have reduced urination
• Feel lightheaded

---

6. Severe Allergic Reactions

Although rare, serious allergic reactions can occur.

Call emergency services immediately if you experience:

• Swelling of the face, lips, tongue, or throat

• Severe rash or itching
• Fainting

These symptoms can be life-threatening.

---

Who Should Avoid Zepbound?

You may not be a candidate if you:

• Have a personal or family history of MTC
• Have MEN 2
• Are pregnant or planning pregnancy
• Have a history of severe allergic reaction to tirzepatide

If you have a history of pancreatitis, gallbladder disease, severe gastrointestinal disease, or kidney problems, discuss risks and benefits carefully with your provider.
