New Safety Signals in GLP-1 Medications

The FDA's latest updates in 2025 highlight several serious safety concerns tied to GLP-1 medications, underscoring the importance of continuous monitoring for the millions of users across the U.S. These findings bring attention to specific risks and the precautions that patients and healthcare providers must prioritize.

Serious Side Effects

One of the most concerning developments is the rise in acute pancreatitis cases among GLP-1 users. This condition, marked by inflammation of the pancreas, can become life-threatening if not treated promptly. Symptoms often include severe abdominal pain, nausea, and vomiting, making early detection crucial.

Another emerging issue is the increase in psychiatric effects. Reports show higher-than-expected rates of mood changes, anxiety, and depression. In some cases documented in 2025, patients experienced severe mood disturbances that required immediate discontinuation of the medication. These mental health challenges can be particularly complex for women, who may already deal with hormonal fluctuations that affect mood.

Reports of gastrointestinal issues tied to tirzepatide have also surged. Cases rose from 1,423 in 2022 to 8,133 in 2024, with 2,771 additional reports in just the first quarter of 2025. Nausea and vomiting in some patients have led to dehydration severe enough to require hospitalization.

Another rare but serious complication is gastroparesis, which slows stomach emptying and leads to persistent digestive problems. This condition can significantly diminish a patient’s quality of life, requiring careful management.

Pregnancy Risks

For women of childbearing age, the safety profile of GLP-1 medications demands extra caution. The FDA advises that GLP-1 medications should not be used during pregnancy due to limited safety data and potential risks to the developing fetus.

Women are encouraged to use reliable contraception while on GLP-1 therapy. Those planning to conceive should work closely with their healthcare provider to discontinue the medication well in advance and explore alternative treatment options.

Telehealth providers like Oana Health have introduced protocols to address these concerns, offering personalized counseling on contraception and family planning as part of their treatment programs.

Long-Term Effects on Nutrition and Metabolism

Beyond the immediate side effects, long-term use of GLP-1 medications may lead to nutritional challenges. One of the most common issues is vitamin B12 deficiency, which can occur as a result of slowed gastric emptying and reduced appetite. Symptoms such as fatigue, weakness, or tingling in the hands and feet may indicate a deficiency, making regular blood tests essential for users on long-term therapy.

Early research also points to potential metabolic changes in patients using GLP-1 medications over extended periods. Alterations in how the body processes and stores nutrients are being studied, which is particularly relevant for women with PCOS, who often face existing metabolic concerns.

To address these risks, healthcare providers now recommend baseline nutritional evaluations before starting GLP-1 therapy, followed by regular monitoring throughout treatment. Dietary counseling and targeted supplementation are often necessary to prevent or manage deficiencies. Staying proactive with these measures can help mitigate the long-term risks associated with GLP-1 use.

Compounded and Unapproved GLP-1 Products: Safety Risks

The rising demand for GLP-1 medications has led to a troubling increase in compounded and unapproved products. These alternatives come with serious health risks that patients need to understand before considering them.

Dangers of Compounded Products

Compounded GLP-1 medications bypass the FDA’s strict quality controls, creating significant safety concerns.

One major issue is dosing errors. Incorrect, missed, or improperly adjusted doses can lead to unpredictable effects, including severe gastrointestinal symptoms from overdosing or poor blood sugar management from underdosing. Real-world data has recorded thousands of cases involving incorrect dosing and hospitalizations tied to compounded GLP-1 products.

Another concern is the variability in formulations. Compounded products may include unregulated ingredients or become contaminated during preparation. Without consistent oversight, these medications can vary in potency and purity from one batch to another. This inconsistency makes it difficult for patients and healthcare providers to predict how the medication will work.

Research shows that patients using compounded GLP-1 medications experience a 30% higher rate of adverse effects compared to those using FDA-approved versions. This stark difference underscores the importance of regulatory oversight in ensuring medication safety. Adding to the problem, counterfeit medications further complicate the risks.

Fake and Counterfeit Medications

The popularity of GLP-1 medications has unfortunately attracted counterfeiters, who produce fake versions that can be dangerous. These products may contain harmful or incorrect ingredients, leading to ineffective treatment or serious health issues.

Counterfeit GLP-1 products can cause allergic reactions, toxicity, or even complete treatment failure. Some have been found to contain unknown substances capable of causing unpredictable and harmful side effects. The FDA has documented numerous cases where counterfeit drugs resulted in toxic reactions and treatment complications. Patients using these fake medications not only risk worsening their condition but may also face new health problems from harmful ingredients.

Certain red flags can help identify fake products. Medications labeled "for research use only" or sold by unlicensed sources are often attempts to dodge FDA regulations while targeting unsuspecting patients.

In September 2025, the FDA issued over 50 warning letters to compounders and manufacturers selling unapproved GLP-1 drugs. This action highlighted the illegal and unsafe nature of these products. The FDA continues to monitor the market and issue safety alerts to protect consumers from fraudulent medications, reinforcing the importance of obtaining treatments through regulated channels.

Getting Medications from Trusted Sources

To avoid these risks, patients should only obtain GLP-1 medications from licensed healthcare providers and FDA-regulated pharmacies. This ensures access to authentic, properly manufactured medications with professional oversight.

Telehealth services like Oana Health connect patients with licensed professionals who prescribe FDA-approved GLP-1 treatments. These medications are then delivered directly to patients’ homes from FDA-regulated pharmacies, ensuring both safety and convenience.

Oana Health’s model prioritizes evidence-based treatments and professional oversight. Patients benefit from proper dosing, consistent monitoring for side effects, and medications sourced from verified suppliers, eliminating the risks associated with compounded or counterfeit products.

If you suspect you’ve received a compounded or counterfeit medication, stop using it immediately and contact your healthcare provider. Additionally, report the incident to the FDA’s MedWatch program to help prevent similar risks for others.

Patient Data: Experiences and Trends

Examining real-world data alongside clinical trial results reveals some striking contrasts, especially for women using GLP-1 medications to manage hormonal conditions like PCOS and insulin resistance. These differences highlight the need for tailored approaches and ongoing safety monitoring.

Clinical Trials vs. Everyday Use

Outcomes in controlled clinical trials often differ from those seen in everyday patient care. For example, real-world users of GLP-1 medications saw an average weight loss of 7.7% with semaglutide and 12.4% with tirzepatide after one year - roughly half the weight loss reported in clinical trials. This difference is largely due to lower dosing and less intensive oversight in real-world settings.

Discontinuation rates also tell an interesting story. In real-world use, 22% of semaglutide users and 16% of tirzepatide users stopped treatment within the first year. By contrast, clinical trials report much lower discontinuation rates, around 10%, as participants receive more consistent monitoring and support.

Cost and side effects often lead to lower dosing in real-world use. Healthcare providers frequently start patients on minimal doses and increase them gradually, whereas clinical trials typically use optimal dosing protocols from the outset. This cautious approach in real-world settings can also contribute to dosing errors. For instance, tirzepatide dosing errors rose dramatically, from 1,715 in 2022 to 15,887 in 2024, and 4,241 in early 2025. These errors include missed doses, double dosing, and incorrect titration - issues rarely seen in tightly controlled trials.

Trends Among Female Patients

Women using GLP-1 medications often report side effects like gastrointestinal discomfort and injection-site reactions, with these issues becoming increasingly common in recent years. Women with PCOS, in particular, face unique challenges, including more pronounced metabolic fluctuations and sensitivity to hormonal shifts caused by rapid weight loss. This group often requires closer monitoring for nutrient deficiencies and hormonal imbalances that could exacerbate their condition.

Injection-site reactions are another growing concern. Reports of these reactions have surged, with 19,334 cases reported in recent periods, including 10,245 in 2024 alone. Many women find these reactions more disruptive than expected, sometimes leading them to discontinue treatment.

Psychiatric side effects, such as mood swings and anxiety, are also emerging as significant concerns. These issues are being reported more frequently, particularly among women managing hormonal conditions, who may already be predisposed to mood-related symptoms. Interestingly, these side effects were not prominent in early clinical trials but have become apparent as the medications are used by a broader and more diverse population.

For women with insulin resistance, treatment outcomes can vary widely. Some experience notable improvements in insulin sensitivity and weight management, while others face tolerability challenges that require adjustments or lead to discontinuation. These variations emphasize the importance of personalized treatment plans, especially for women dealing with hormonal imbalances or conditions like PCOS.

The Importance of Ongoing Monitoring

Given the complexities of dosing and the need for dose escalation, regular follow-ups are crucial. Adverse effects such as fatigue, headaches, and blood sugar fluctuations remain common in real-world scenarios, underscoring the need for continuous oversight.

Emerging safety concerns, including psychiatric symptoms and nutritional deficiencies, highlight the value of post-market surveillance. These issues often only come to light after the medications are used by a diverse range of patients over extended periods. Real-world data collection plays a vital role in identifying and addressing these risks.

Telehealth platforms like Oana Health are stepping in to meet these monitoring needs. By offering virtual check-ins and direct access to licensed medical professionals, they help detect side effects early, support adherence, and enable timely dose adjustments. This approach is particularly beneficial for women managing complex hormonal conditions alongside GLP-1 therapy.

As more women turn to these medications for conditions like PCOS and insulin resistance, the growing pool of patient data continues to shape treatment strategies and safety guidelines. Personalized care and vigilant monitoring remain essential to optimizing outcomes and minimizing risks for these patients. By leveraging real-world insights, healthcare providers can better address the unique challenges faced by women using GLP-1 therapies.

Effects on Women's Health and PCOS Treatment

For women dealing with PCOS, weight management, and hormonal health, the evolving safety signals surrounding GLP-1 medications bring both opportunities and challenges. These drugs show potential in tackling key PCOS symptoms like insulin resistance and weight issues. However, they also raise important questions about hormonal interactions and the implications for reproductive health. These concerns tie closely to the broader safety topics discussed earlier.

Interactions With Hormonal Treatments

GLP-1 medications can impact the effectiveness of other hormonal treatments. For instance, because these drugs affect how the gastrointestinal system processes food, they may reduce the absorption of oral contraceptives. Women taking metformin for PCOS might also experience heightened gastrointestinal side effects, potentially requiring adjustments to their medication timing or dosage.

The picture becomes even more complex with anti-androgen medications like spironolactone. While some women report benefits from combining these treatments with GLP-1 medications, the full scope of these interactions remains unclear and calls for careful monitoring. Additionally, starting GLP-1 therapy has been linked to metabolic changes, which might show up as irregular blood sugar levels or altered menstrual cycles.

Considerations for Women of Childbearing Age

For women planning to conceive, managing the transition off GLP-1 therapy requires close coordination with healthcare providers. These medications are typically paused before pregnancy, and this shift can bring changes in PCOS symptoms that need careful monitoring.

Some women with PCOS have reported improved menstrual cycles and lower androgen levels while on GLP-1 therapy, which could enhance fertility. However, since the treatment is discontinued before conception, these benefits might not carry over into pregnancy. Navigating this transition can be challenging, making supportive care and clear communication essential for setting realistic expectations.

Personalized Care Through Telehealth

Telehealth has emerged as a valuable tool for tailoring GLP-1 therapy to the needs of women managing PCOS and other hormonal conditions. Platforms like Oana Health provide prescription-based treatments designed to address hormonal health. Through virtual consultations, licensed healthcare providers can monitor how GLP-1 medications interact with other treatments by tracking menstrual cycles, androgen levels, and metabolic markers.

This approach eliminates the need for frequent in-person visits, offering comprehensive care remotely. Medications are delivered directly through FDA-regulated pharmacies, ensuring patients receive verified products and reducing the risk of counterfeit or compounded drugs. Regular virtual check-ins allow for early detection of side effects - whether gastrointestinal, hormonal, or psychiatric - enabling timely adjustments to treatment plans.

For many women with PCOS, telehealth creates a supportive, judgment-free space to discuss personal concerns like weight management, fertility, or unwanted hair. By streamlining care and improving access, telehealth makes it easier and more affordable to manage PCOS effectively.

Conclusion: Key Points on GLP-1 Safety Signals

The growing safety concerns around GLP-1 medications emphasize the importance of informed decision-making and consistent monitoring in patient care. While these medications have shown promise in managing weight and improving metabolic health, emerging data reveal trends that demand attention from both patients and healthcare providers.

For instance, reports of dosing errors with tirzepatide surged from 1,715 in 2022 to an alarming 15,887 in 2024, with 4,241 cases already reported in early 2025. This sharp rise illustrates how quickly issues can surface as these medications become more widely used outside of controlled clinical environments. Additionally, real-world outcomes often differ from clinical trial results. For example, semaglutide users experienced an average weight loss of 7.7% compared to the 15% reported in trials, and 22% of patients discontinued treatment within the first year. These discrepancies highlight the need for ongoing oversight and tailored patient support.

Another pressing concern is the risk posed by unregulated products. In September 2025 alone, the FDA issued over 50 warning letters to GLP-1 compounders and manufacturers, reflecting the widespread availability of unsafe products. Patients who turn to compounded or counterfeit medications face serious risks, including inconsistent dosing, contamination, and potentially harmful side effects.
