Tirzepatide Side Effects and Safety: What the FDA Record Shows

Tirzepatide Side Effects are documented on the FDA prescribing label, and reported separately by patients and doctors to the FDA’s adverse event system. This page sets out what the official record actually says about Tirzepatide: what it is approved to treat, what the label warns about, its recall history, and what the reported side effects are — along with what those figures do and do not mean.

Before you read on. Do not stop taking a prescribed medicine, or change how you take it, because of anything you read here. Talk to the prescriber or pharmacist who knows your medical history first.

What Tirzepatide Is Prescribed For, and Where Tirzepatide Side Effects Come From

According to the FDA label, ® is indicated in combination with a reduced-calorie diet and increased physical activity: to reduce excess body weight and maintain weight reduction long term in adults with obesity or adults with overweight in the presence of at least one weight-related comorbid condition. to treat moderate to severe obstructive sleep apnea (OSA) in adults with obesity. […]

Two separate official sources describe tirzepatide side effects. The prescribing label records what was observed in clinical trials, where the drug was compared against a control group. The FDA’s adverse event database records what patients and clinicians have reported since approval, which is a much larger but far less controlled picture. Both appear below, and they answer different questions.

The FDA Boxed Warning on Tirzepatide

This medicine carries a boxed warning

WARNING: RISK OF THYROID C-CELL TUMORS In rats, tirzepatide causes dose-dependent and treatment-duration-dependent thyroid C-cell tumors at clinically relevant exposures. It is unknown whether ZEPBOUND causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans as human relevance of tirzepatide-induced rodent thyroid C-cell tumors has not been determined [see Warnings and Precautions ( 5.1 ) and Nonclinical Toxicology ( 13.1 )].

ZEPBOUND is contraindicated in patients with a personal or family history of MTC or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2) [see Contraindications ( 4 )] . Counsel patients regarding the potential risk for MTC with the use of ZEPBOUND and inform them of symptoms of thyroid tumors (e.g., a mass in the neck, dysphagia, dyspnea, persistent hoarseness). […]

A boxed warning is the most serious warning the FDA requires on a prescription label. It does not mean the medicine should not be used. It means there is a specific risk serious enough that the FDA requires it to appear at the very top of the prescribing information, so that prescribers weigh it deliberately for each patient.

Prescribers see this warning every time they consult the label. If it concerns you, it is a reasonable thing to raise at your next appointment and ask how it applies to your own situation.

Warnings Beyond the Common Tirzepatide Side Effects

The label’s warnings and precautions section describes risks the FDA requires prescribers to weigh. For Tirzepatide it covers: evere Gastrointestinal Adverse Reactions: Use has been associated with gastrointestinal adverse reactions, sometimes severe. ZEPBOUND is not recommended in patients with severe gastroparesis. ( 5.2 ) Acute Kidney Injury Due to Volume Depletion: Monitor renal function in patients reporting adverse reactions that could lead to volume depletion. ( 5.3 ) Acute Gallbladder Disease: Has been reported in clinical trials. If cholecystitis is suspected, gallbladder studies and clinical follow-up are indicated.

( 5.4 ) Acute Pancreatitis: Has been observed in patients treated with GLP-1 receptor agonists, or ZEPBOUND. Discontinue if pancreatitis is suspected. ( 5.5 ) Hypersensitivity Reactions: Serious hypersensitivity reactions (e.g., anaphylaxis, angioedema) have been reported postmarketing with tirzepatide. If suspected, advise patients to promptly seek medical attention and discontinue ZEPBOUND. ( 5.6 ) Hypoglycemia: Concomitant use with insulin or an insulin secretagogue may increase the risk of hypoglycemia, including severe hypoglycemia. […]

These are the risks the FDA has judged significant enough to state formally, and they sit apart from the routine tirzepatide side effects most people ask about. They apply to different patients to very different degrees, which is why the same medicine can be routine for one person and unsuitable for another.

Tirzepatide Side Effects Listed on the FDA Label

The label’s adverse reactions section records what was observed in clinical trials: he following serious adverse reactions are described below or elsewhere in the prescribing information: Risk of Thyroid C-cell Tumors [see Warnings and Precautions ( 5.1 )] Severe Gastrointestinal Adverse Reactions [see Warnings and Precautions ( 5.2 )] Acute Kidney Injury Due to Volume Depletion [see Warnings and Precautions ( 5.3 )] Acute Gallbladder Disease [see Warnings and Precautions ( 5.4 )] Acute Pancreatitis [see Warnings and Precautions ( 5.5 )] Hypersensitivity Reactions [see Warnings and Precautions ( 5.6 )] Hypoglycemia [see Warnings and Precautions ( 5.7 )] Diabetic Retinopathy Complications in Patients with Type 2 Diabetes Mellitus [see Warnings and Precautions ( 5.8 )] Pulmonary Aspiration During General Anesthesia or Deep Sedation [see Warnings and Precautions ( 5.9 )] The most common adverse reactions, reported in ≥5% of patients treated with ZEPBOUND are: nausea, diarr […]

Trial data is the most reliable source for how common tirzepatide side effects are, because the people taking the drug were compared against people who were not. A symptom that appeared just as often in the control group is not caused by the medicine.

Reported Tirzepatide Side Effects in the FDA Database

Reported tirzepatide side effects — and what these numbers do not mean

The FDA’s adverse event database holds 140,435 reports mentioning Tirzepatide, of which 23,958 were classified as serious.

Read those numbers carefully. An adverse event report means somebody told the FDA that something happened to a person taking this medicine. It is not a finding that the medicine caused it. Reports are submitted voluntarily by patients, families, doctors and manufacturers; nobody verifies them; and the same event can be reported more than once.

Report volume tracks how many people take a drug, how new it is, and how much attention it is getting. A widely prescribed medicine will always show more reports than a rarely used one, and reports rise sharply when a drug is in the news or in litigation. A large number here does not mean a drug is dangerous, and a small number does not mean it is safe.

Most frequently reported Reports
Nausea 14,290
Injection Site Pain 13,177
Extra Dose Administered 9,000
Diarrhoea 8,305
Vomiting 6,887
Constipation 5,248
Injection Site Haemorrhage 5,035
Injection Site Erythema 4,771

Tirzepatide Recall History

The FDA’s enforcement database shows no recall records for Tirzepatide products in the period covered by the current data. That is a statement about recalls of the product, not about the medicine’s safety profile, which is a separate question addressed by the label and the warnings on it.

Recalls are usually about a manufacturing or packaging problem affecting particular batches, not about the medicine itself. You can check for current recalls any time on the FDA recalls page.

Is Tirzepatide the Subject of Litigation?

As of the date on this page, we are not tracking consolidated federal litigation over Tirzepatide. Safety questions have been raised about this medicine, and questions being raised is not the same thing as a case being filed or proven.

We monitor federal court filings and FDA safety communications, and this page is updated when the record changes. Our active case pages list the drug and device litigation currently underway.

Litigation Timeline

Litigation does not mean a medicine has been proven to cause harm. Do not stop taking a prescribed medicine because of anything you read here — talk to the prescriber or pharmacist who knows your history.

If You Are Worried About Tirzepatide Side Effects

Concern about tirzepatide side effects is a good reason to have a conversation, and not a reason to act alone. Do not stop taking a prescribed medicine, or change how you take it, because of anything you read here. Talk to the prescriber or pharmacist who knows your medical history first. Stopping some medicines abruptly carries risks of its own, and your prescriber can tell you whether that applies to yours.

Write down what you have noticed and when it started before the appointment. Not everything that happens while taking a medicine is one of its tirzepatide side effects, and a specific account — what changed, when, and how often — is what lets a clinician tell the difference.

You can also report a side effect directly to the FDA through MedWatch. Reports from patients are part of how safety signals are detected, and filing one takes a few minutes.

Frequently Asked Questions

What are the most commonly reported tirzepatide side effects?

In FDA reports, the most frequently mentioned are nausea, injection site pain, extra dose administered. The label’s own adverse reactions section, drawn from clinical trials, is the better guide to how common a side effect actually is, because reports to the FDA are not collected in a way that supports rates.

Has Tirzepatide been recalled?

The FDA enforcement database shows no recall records for Tirzepatide products in the current data. Check the FDA recalls page for anything more recent.

Does Tirzepatide have a boxed warning?

Yes. The boxed warning is reproduced above. It is the most serious warning the FDA requires, and it exists so that prescribers weigh a specific risk for each patient rather than overlooking it.

Do the FDA report numbers tell me how common these tirzepatide side effects are?

No. Reports are unverified, anyone can file one, and the total mostly reflects how many people take the medicine and how much attention it is getting. A high count is not evidence of danger, and a low one is not evidence of safety. Clinical trial data on the label is the source that supports rates.

Where can I check tirzepatide side effects for the exact product I have?

DailyMed holds the current FDA label for every marketed product, searchable by the name on your packaging. Different manufacturers and formulations of the same medicine can have slightly different labels, so checking the one you actually have is worth the two minutes.
