Zepbound (tirzepatide) is an FDA-approved medication for chronic weight management that works as a dual GIP and GLP-1 receptor agonist. While patients may wonder does Zepbound cause yeast infections, this side effect is not listed in the FDA prescribing information or identified in clinical trials. Understanding the relationship between Zepbound treatment and infection risk requires examining both the medication's direct effects and indirect factors associated with weight loss therapy, concurrent medications, and underlying metabolic conditions that may influence susceptibility to Candida overgrowth.
Quick Answer: Zepbound (tirzepatide) does not directly cause yeast infections and they are not listed as a recognized side effect in FDA prescribing information or clinical trials.
Zepbound (tirzepatide) is an FDA-approved prescription medication for chronic weight management in adults with obesity or overweight with at least one weight-related comorbid condition. As a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist, Zepbound works by mimicking natural hormones that regulate appetite, food intake, and glucose metabolism. While the exact mechanism for weight management is not fully understood, this action helps patients achieve significant weight loss when combined with a reduced-calorie diet and increased physical activity.
The most commonly reported side effects of Zepbound are gastrointestinal in nature, occurring in a substantial proportion of patients during clinical trials. These include nausea, diarrhea, vomiting, constipation, abdominal pain, and dyspepsia. These effects typically emerge during dose escalation and often diminish over time as the body adjusts to the medication. According to FDA prescribing information, approximately 6% of patients receiving Zepbound discontinued treatment due to adverse reactions compared to 2-3% receiving placebo, with gastrointestinal events being the most common reasons for discontinuation.
Other documented side effects include injection site reactions, fatigue, hypoglycemia (particularly when used with insulin or insulin secretagogues), and increased heart rate. Serious but rare risks include pancreatitis, gallbladder disease, acute kidney injury, and hypersensitivity reactions. The medication carries a boxed warning regarding thyroid C-cell tumors observed in rodent studies and is contraindicated in patients with a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN2). Patients should report symptoms such as a lump in the neck, difficulty swallowing, or persistent hoarseness.
Importantly, Zepbound may delay gastric emptying, which can reduce the absorption of oral medications including oral contraceptives. Women using oral contraceptives are advised to use additional contraception for 4 weeks after initiating Zepbound and for 4 weeks after each dose increase.

Yeast infections, medically termed vulvovaginal candidiasis or candidal infections, are not listed as a recognized side effect in the FDA-approved prescribing information for Zepbound. Clinical trials evaluating tirzepatide for weight management did not identify yeast infections as a statistically significant adverse event directly attributable to the medication. This absence from official documentation indicates there is no established evidence of increased risk of yeast infections with Zepbound use.
However, the question arises because patients taking Zepbound may experience various physiological changes during treatment that could theoretically influence infection susceptibility. Weight loss medications can alter metabolic parameters, dietary patterns, hydration status, and overall health conditions—factors that may indirectly affect the body's microbial balance. It is important to distinguish between a direct pharmacological effect of the medication and indirect consequences of the weight loss process or lifestyle modifications accompanying treatment.
It's worth noting that some patients may be taking Zepbound alongside other medications that do increase the risk of genital mycotic infections. In particular, sodium-glucose cotransporter-2 (SGLT2) inhibitors such as empagliflozin or dapagliflozin are well-documented to increase the risk of genital yeast infections and may confound attribution of symptoms. When yeast infections occur during Zepbound treatment, they are more likely related to other risk factors rather than a direct medication effect. Patients concerned about new or recurrent infections should discuss these symptoms with their healthcare provider to identify the underlying cause and receive appropriate treatment.
While Zepbound itself does not directly cause yeast infections, several factors associated with weight loss treatment may create conditions that could potentially influence susceptibility to Candida overgrowth. Understanding these potential relationships helps patients and clinicians address the root causes rather than attributing symptoms solely to the medication.
Pre-existing or undiagnosed diabetes represents an important consideration. Many patients prescribed Zepbound for weight management have metabolic syndrome, prediabetes, or type 2 diabetes. Elevated blood glucose levels create an environment conducive to yeast proliferation, making hyperglycemia one of the strongest modifiable risk factors for vulvovaginal candidiasis. While Zepbound improves glycemic control in many patients, those with poorly controlled glucose levels before or during early treatment may remain at elevated risk for yeast infections until metabolic parameters stabilize.
Concurrent medication use is another significant factor. SGLT2 inhibitors, commonly prescribed for type 2 diabetes, substantially increase the risk of genital mycotic infections due to their mechanism of increasing urinary glucose excretion. Patients taking both Zepbound and an SGLT2 inhibitor may incorrectly attribute yeast infections to Zepbound rather than the SGLT2 inhibitor.
Other contributing factors include:
Antibiotic use: Concurrent antibiotic therapy for unrelated infections disrupts normal vaginal flora, allowing Candida overgrowth
Hormonal factors: Hormonal fluctuations may affect vaginal pH and microbiome composition
Hygiene practices: Changes in exercise routines may affect personal hygiene
Vulvovaginal candidiasis should be distinguished from cutaneous candidiasis (fungal skin infections), which can occur in skin folds and may be influenced by factors such as increased sweating or prolonged moisture exposure. Identifying these potential contributors allows for targeted interventions that address the actual cause rather than unnecessarily discontinuing beneficial weight management therapy.
Recognizing yeast infection symptoms promptly enables appropriate treatment and prevents unnecessary discomfort. Vulvovaginal candidiasis typically presents with characteristic signs including intense itching and irritation of the vulva and vaginal opening, often described as the most bothersome symptom. Patients may notice abnormal vaginal discharge that appears thick, white, and cottage cheese-like in consistency, though discharge may be minimal in some cases. Additional symptoms include burning during urination, pain or discomfort during sexual intercourse, and redness or swelling of the vulvar tissues.
For patients experiencing their first suspected yeast infection or those with atypical symptoms, medical evaluation is essential to confirm the diagnosis. Self-diagnosis can be inaccurate, as other conditions including bacterial vaginosis, trichomoniasis, contact dermatitis, and sexually transmitted infections may present with similar symptoms. Healthcare providers can perform a simple examination and microscopic evaluation of vaginal discharge to definitively identify Candida organisms and rule out alternative diagnoses.
Once confirmed, yeast infections typically respond well to antifungal treatments available both over-the-counter and by prescription. Options include:
Topical azole antifungals: Clotrimazole, miconazole, or tioconazole creams or suppositories used for 1-7 days depending on formulation strength
Oral fluconazole: A single 150 mg dose for uncomplicated infections, available by prescription
Combination therapy: Topical treatments for external symptoms plus oral medication for internal infection
Pregnant patients should use topical azole therapy for 7 days and avoid oral fluconazole. For recurrent vulvovaginal candidiasis (four or more episodes annually), CDC guidelines recommend an induction regimen of fluconazole 150 mg every 72 hours for three doses, followed by weekly maintenance therapy for 6 months.
Patients should complete the full treatment course even if symptoms improve quickly. Preventive measures during Zepbound treatment include maintaining good glycemic control, wearing breathable cotton underwear, avoiding tight-fitting clothing, changing out of wet exercise clothing promptly, and limiting unnecessary antibiotic use. Probiotic supplementation, particularly with Lactobacillus species, has shown mixed and limited evidence for prevention and is not consistently endorsed in clinical guidelines.
While yeast infections are generally not medical emergencies, certain situations require prompt professional evaluation to ensure appropriate diagnosis and treatment. Patients should contact their healthcare provider if they experience symptoms suggestive of a yeast infection for the first time, as self-diagnosis without confirmation can lead to inappropriate treatment and delayed recognition of other conditions. First-time infections warrant medical assessment to establish the correct diagnosis and rule out sexually transmitted infections or other gynecological conditions that may present similarly.
Recurrent yeast infections—defined as four or more confirmed episodes within 12 months—necessitate comprehensive evaluation. Frequent recurrences may indicate inadequately controlled diabetes, immunosuppression, antibiotic overuse, concurrent SGLT2 inhibitor therapy, or other underlying health conditions requiring specific management. Patients taking Zepbound who develop recurrent infections should undergo hemoglobin A1c testing to assess glycemic control, as even modest elevations in blood glucose can predispose to Candida overgrowth. Additional evaluation may include assessment for HIV or other immunocompromising conditions.
Immediate medical attention is warranted if patients develop:
Severe symptoms: Extensive swelling, severe pain, or ulceration that interferes with daily activities
Systemic signs: Fever, chills, or feeling generally unwell, which may indicate a more serious infection
Treatment failure: Symptoms persisting or worsening after completing a full course of antifungal therapy
Unusual discharge: Foul-smelling, green, gray, or bloody discharge suggesting alternative diagnoses
Pelvic or abdominal pain: May indicate pelvic inflammatory disease or other serious conditions
Pregnancy: Yeast infections during pregnancy require provider-directed treatment with pregnancy-safe medications
Immunocompromised patients and pregnant women should avoid self-treatment and seek clinician guidance. Patients should never discontinue Zepbound without consulting their prescribing physician, even if they suspect the medication is contributing to recurrent infections. The substantial improvements in cardiometabolic risk factors from successful weight management typically outweigh the inconvenience of treatable yeast infections. Healthcare providers can work collaboratively with patients to optimize glycemic control, address modifiable risk factors, and implement preventive strategies while continuing beneficial weight management therapy.
