Zepbound dizziness: causes and how to manage

Zepbound (tirzepatide) may cause dizziness in some users due to its effects on blood pressure, blood sugar, and hydration. If you’re taking this weight loss medication, find out how long Zepbound dizziness typically lasts and what you can do to reduce this side effect.

Yes, Zepbound can cause dizziness in some people. According to Zepbound's prescribing information, dizziness is a known side effect of the medication. In placebo-controlled clinical trials, dizziness occurred in 4%–5% of people taking Zepbound compared with 2% of those taking a placebo.

A large meta-analysis found that tirzepatide was associated with about twice the odds of dizziness compared to placebo, but dizziness was still far less common than other side effects, like nausea, diarrhea, and vomiting.

See if you qualify

Studies suggest Zepbound may cause dizziness in some people due to its effects on blood pressure, blood sugar, and hydration levels. Here’s what the research shows:

Blood pressure changes

Research shows that tirzepatide can lower blood pressure as a result of weight loss. For some people, this drop in blood pressure may cause dizziness or lightheadedness. 

In one clinical trial, dizziness was the most common blood pressure-related side effect, but more severe effects of low blood pressure, like fainting, only occurred in fewer than 1% of participants.

Blood sugar changes

One possible explanation for Zepbound dizziness is the drug’s effects on blood sugar levels. Studies show that tirzepatide can contribute to hypoglycemia, or low blood sugar, especially in people who take insulin or sulfonylureas to manage diabetes. Hypoglycemia is known to cause symptoms like dizziness and lightheadedness.

Dehydration

Zepbound commonly causes gastrointestinal side effects like nausea, diarrhea, and vomiting, which could lead to dehydration. When you’re dehydrated, your blood pressure may drop, potentially contributing to dizziness. According to Zepbound's prescribing information, cases of low blood pressure were often linked to GI side effects and dehydration.

It’s unclear how long dizziness on Zepbound lasts because researchers haven’t measured this directly. However, the drug’s prescribing information notes that the majority of common side effects, like nausea, vomiting, and diarrhea, occur with dose escalations and decrease over time, as people get used to the medication. Presumably, this may be the case for Zepbound dizziness, too.

If you’re feeling dizzy or lightheaded on Zepbound, making a few changes to your diet and lifestyle can help. Here are some strategies to consider: 

Change positions slowly

You may find that getting up too fast makes your dizziness worse. Studies on dizziness suggest that people experiencing these symptoms should change positions slowly to reduce their symptoms. Staring at a stationary object before getting up can help prevent dizziness from coming on for some people. 

Eat small, regular meals

Zepbound can reduce your appetite, making it easy to skip meals or eat less than usual, which can lead to dizziness. You can lower this risk by eating small, balanced meals throughout the day. 

If you have diabetes or take insulin or a sulfonylurea drug, eating regular meals can also help reduce your risk of hypoglycemia, which can cause dizziness. Remember to tell your healthcare provider about all the medications you are taking. If you are starting Zepbound and are already taking other medications to help lower your blood sugar, your healthcare provider may decrease the doses of those medications to help prevent hypoglycemia. 

Hydrate 

If you think your dizziness might be related to dehydration, try to increase your fluid intake. If you've lost fluids from vomiting or diarrhea, an oral rehydration solution or electrolyte-containing drink may also help replace both fluids and electrolytes. Try to avoid caffeine or alcohol, as these options can actually worsen dehydration.

Get started

Dizziness on Zepbound may go away on its own, but you should stop taking the medication and contact a healthcare provider if you experience the following side effects:

• Severe dizziness that doesn’t go away or keeps coming back

• Persistent nausea, vomiting, or diarrhea, especially if you're unable to keep fluids down, as this can lead to severe dehydration and kidney problems

• Dark urine, which could be a sign of severe dehydration

• Severe symptoms of low blood sugar, such as shakiness, confusion, blurred vision, and slurred speech

• Symptoms of pancreatitis, including severe abdominal pain that may spread to your back, with or without nausea or vomiting

• Symptoms of gallbladder disease, such as upper abdominal pain, fever, yellowing of your skin or eyes, or clay-colored stools

• Signs of an allergic reaction, including swelling of your face, lips, tongue, or throat, trouble breathing or swallowing, severe rash or itching, fainting, or a rapid heartbeat

A healthcare provider can determine whether the medication is safe for you and help rule out other health conditions. This list is not comprehensive, and if you are experiencing any worrisome symptoms, be sure to reach out to your healthcare provider and seek emergency medical attention if needed. 

Does Zepbound cause dizziness? For some people, it can. But it’s less common than other side effects, and there are ways to manage it. Here’s what we know:

• Zepbound can cause dizziness in some people, but it’s not too common. Research suggests the dizziness people experience may be related to changes in blood pressure, blood sugar, or dehydration, especially during the first few weeks of treatment or after a dose increase.

• Simple lifestyle tweaks may help reduce Zepbound dizziness. Staying hydrated, eating regular meals, and changing positions slowly may help you manage this side effect.

• Don't ignore severe or ongoing dizziness. Contact your healthcare provider if your dizziness doesn't improve or if you experience persistent vomiting, severe dehydration, signs of low blood sugar, or severe abdominal pain.
