Fears for safety of unborn babies after weight-loss jab alert
Pregnant women have been warned by the medical watchdog not to take weight-loss drugs as there is currently no guarantee there won't be any adverse affect on the baby.
The Medicines and Healthcare products Regulatory Agency (MHRA) issued an alert over a lack of evidence for pregnancy safety for the jabs, which include Ozempic, Mounjaro, Wegovy, Saxenda and Victoza.
The MHRA said the drugs – which are glucagon-like peptide-1 receptor agonists (GLP-1 or GLP-1 RAs) – must not be taken during pregnancy, while trying to get pregnant, or during breastfeeding.
Anyone who gets pregnant while using the drugs should also stop taking the medicine, it added.
It said: 'This is because there is not enough safety data to know whether taking the medicine could cause harm to the baby.'
In some cases, women are also advised to continue using contraception for up to two months between stopping the medicine and trying to get pregnant.
The MHRA said effective contraception includes the oral contraceptive pill, contraceptive implants, the coil and condoms.
Those patients taking Mounjaro – which may reduce the effectiveness of oral contraceptives in people who are overweight – should also use condoms if they are on the Pill.
The injections have been previously linked to a 'baby boom', with women reporting online that they have had surprise 'Ozempic babies' despite using contraception.
To date, the MHRA has received more than 40 reports relating to pregnancy among women on the drugs.
The MHRA said: 'This only applies to those taking Mounjaro and is especially important for the four weeks after starting Mounjaro and after any dose increase.'
The advice on contraception is also contained in patient information leaflets that come with the medicines.
MHRA data shared with by the PA news agency shows it has received 26 pregnancy-related reports for Mounjaro.
It is not necessary for women to say whether the pregnancy was unintentional, though one report did say the pregnancy was such.
There have been a further eight reports relating to pregnancy in people taking semaglutide (the ingredient in Ozempic and Wegovy).
A further nine have been recorded for liraglutide (Victoza or Saxenda), of which one recorded the pregnancy was unintentional.
The MHRA is also reminding people that weight-loss jabs should not be bought from unregulated sellers such as beauty salons or via social media, or taken without speaking to a health professional.
Anyone who suspects they have had an adverse reaction or suspects their drug is not a genuine product, should report it to the MHRA Yellow Card scheme.
Dr Alison Cave, MHRA chief safety officer, said: 'Skinny jabs are medicines licensed to treat specific medical conditions and should not be used as aesthetic or cosmetic treatments.
'They are not a quick fix to lose weight and have not been assessed to be safe when used in this way.
'Our guidance offers patients a 'one-stop shop' for our up-to-date advice on how to use these powerful medicines safely.
'This guidance should not be used as a substitute to reading the patient information leaflet or having a conversation with a healthcare professional as part of the prescribing process.'
The latest guidance also reminds patients taking jabs of the symptoms to look out for in the event of acute pancreatitis which, although uncommon, can be serious.
The main symptom is severe pain in the stomach that radiates to the back and does not go away, and people should seek immediate medical help.
GLP-1 or GLP-1 RAs help people feel fuller by mimicking a natural hormone released after eating.
Some, like Mounjaro, also act on a second hormone involved in appetite and blood sugar control.
Jasmine Shah, medication safety officer at the National Pharmacy Association, said: 'Pharmacists urge women taking GLP-1 medicines to note this important new guidance from the MHRA published today and use effective contraception.
'Community pharmacies have been experiencing unprecedented levels of interest for weight-loss injections.
'It is therefore important that regulations and guidance keep pace with this demand and that patient safety is put at the heart of everything we do.
'Medicines are not like ordinary goods for sale; they must be handled with great care because they have the power to harm as well as to heal.
'We also reiterate warnings from the MHRA to avoid any potential fake weight loss injections sold on social media or via beauty salons, which could pose a serious risk to someone's health.
'We urge anyone who have concerns about this medication to speak to their pharmacist for advice.'

GLP-1 Drugs Linked to Age-Related Macular Degeneration, Study Finds
GLP-1 drugs are associated with a higher risk of 'wet' age-related macular degeneration in people with type 2 diabetes, according to a new study. Researchers found that the risk substantially increased the longer people were prescribed a GLP-1 drug, particularly those containing semaglutide. GLP-1 medications like Ozempic and Wegovy have surged in popularity as weight loss treatments, but ophthalmologists say their potential risks to eye health are not well understood. GLP-1 drugs are linked to a significantly higher risk of developing neovascular or 'wet' age-related macular degeneration, according to new research. The study, conducted by researchers at the University of Toronto, found that people with type 2 diabetes who were prescribed GLP-1s were more than twice as likely to develop wet AMD as those who weren't. The study also found that the longer subjects were treated with these medications, the greater their risk of developing wet AMD. Neovascular age-related macular degeneration, commonly known as wet AMD, is the less common but more aggressive form of age-related macular degeneration, and a leading cause of irreversible vision loss among older adults in the United States. The findings, published on June 5 in JAMA Ophthalmology, suggest that doctors and patients should be aware of the potential risks, even though the chance of developing the condition remains relatively low. GLP-1 drugs, a class of blockbuster diabetes and obesity drugs sold under brand names like Ozempic and Wegovy, have surged in popularity in recent years. They offer a range of substantial benefits, including weight loss, improved blood sugar levels, and reduced cardiovascular disease risk. Despite these benefits, ophthalmologists say the impact of GLP-1 drugs on eye health is not well understood. Studies have identified an association between the medications and other eye conditions, including diabetic retinopathy and non-arteritic anterior ischemic optic neuropathy (NAION). While the findings don't establish a clear causal link between GLP-1 drugs and eye disease, experts say there's still reason for caution. 'The dose-response effect we observed — where longer GLP-1 receptor agonist exposure was associated with higher risk — strengthens the argument that this association may reflect a true biological effect rather than being due to confounding factors,' said study co-author Andrew Mihalache, MD(C), of the Temerty Faculty of Medicine at the University of Toronto, Canada. 'Seeing a graded relationship like this suggests that prolonged exposure could play a causal role in increasing risk. However, this needs to be confirmed in future studies,' he told Healthline. Long-term GLP-1 drug use may triple wet AMD risk Drawing on health records from Ontario, Canada, researchers at the University of Toronto analyzed nearly 140,000 adults with type 2 diabetes to investigate a possible link between GLP-1 use and wet AMD. The retrospective study tracked patient outcomes over a three-year period, using data collected between 2020 and 2023. Roughly one-third of participants — about 46,000 people — had been prescribed a GLP-1 drug for at least six months. The rest had not. In the vast majority of cases (97.5%), that drug was semaglutide, the active ingredient in Ozempic and Wegovy. The average participant was 66, and the cohort was almost evenly divided by sex, with females representing 46.6% of the group. On average, those who were prescribed a GLP-1 drug were more than twice as likely to be diagnosed with wet AMD. However, that number doesn't tell the full story. People who took GLP-1 drugs for longer experienced progressively greater risk. Those who had only taken their medication for 6–18 months actually had a slightly lower risk than those who didn't take the medication. However, at the 18–30 month mark, GLP-1 users' risk of developing wet AMD more than doubled compared to non-users. And those taking the drugs for 30 months or longer had more than triple the risk. 'This was definitely surprising, especially given the growing enthusiasm for GLP-1 receptor agonists for their cardiovascular and metabolic benefits. It really highlights the need for further investigation into their ocular safety profile,' first study author Reut Shor, MD, of the Department of Ophthalmology and Vision Sciences at the University of Toronto, Canada, told Healthline. Despite the increase in risk, the absolute risk of developing wet AMD was still low: 0.2% among those taking a GLP-1 and 0.1% among those who didn't. Do GLP-1 drugs harm eye health? While not definitive, the study raises further questions about the potential risks posed by GLP-1 drugs for eye health. Prior studies have also identified links between GLP-1s and other forms of eye disease in people with type 2 diabetes. In a major phase 3 semaglutide trial in 2016, researchers identified that type 2 diabetes patients taking semaglutide had a higher risk of complications of diabetic retinopathy compared to a placebo. Those findings were published in The New England Journal of Medicine. However, other studies have provided conflicting evidence. A retrospective 2024 study evaluated nearly 700 subjects with type 2 diabetes who were taking a GLP-1 drug and found no association between GLP-1s and worsening retinopathy. Also in 2024, researchers found that patients with type 2 diabetes who were prescribed semaglutide were at greater risk of NAION compared to those who weren't. NAION is a condition that causes sudden blindness, typically just in one eye, due to a lack of blood flow to the optic nerve. The mechanism for why GLP-1 drug use may lead to wet AMD is not well established, but a predominant theory is that lowering blood sugar rapidly leads to a lack of oxygen in the retina. 'When you make the retina more hypoxic, which is what the GLP-1s do, it basically pushes it further over the threshold, causing more abnormal blood vessels to grow,' said Linda Lam, MD, MBA, an ophthalmologist with Keck Medicine of USC, who wasn't involved in the research. Abnormal blood vessel growth in the eye is the hallmark of wet AMD. While GLP-1s offer many health benefits, eye disease risk must be considered in some populations, Lam told Healthline. 'In this particular group of patients who are older, who are diabetics, I really would caution against the extended use of GLP-1s,' she said. Lam reiterated the importance of annual eye exams for the general population, but in particular for those with diabetes, to identify and diagnose eye disease early on. People with type 2 diabetes, especially those taking a GLP-1 drug, should be aware of the signs and symptoms of vision loss and consult with their doctor immediately. These include:

Diabetes startup Omada Health finally went public after 14 years. Here's who made bank.
Omada Health just became the second digital health company to IPO this year. The chronic care company saw its shares jump Friday morning by over 38% above its initial price. Here's what Omada's major investors' stakes are worth after the public market debut. Omada Health just went public at a $1.1 billion valuation — 14 years after its founding. It's the second digital health IPO of the year, following physical therapy company Hinge Health, which went public on May 21. The two IPOs come after a multiyear drought for healthcare public market debuts. And so far, Omada's IPO hasn't disappointed. While the chronic care company priced its initial shares at $19, its stock opened at $23 a share and jumped as high as $28.40 Friday morning, nearly a 50% increase. Omada Health launched in 2011 to provide virtual care for prediabetes, making its name in the years following for diabetes management. In recent years, its business has surged in new areas beyond diabetes care. Omada's weight care business has boomed as more patients taking GLP-1 drugs like Ozempic for weight loss seek companion care. The San Francisco-based company says most of its new employer and health plan clients approach Omada initially, interested in its metabolic health track. Omada's initial valuation of $1.1 billion is roughly where it was privately valued. Omada's last private fundraise, a $192 million Series E round announced in February 2022, put Omada's valuation over $1 billion. It's perhaps the best outcome Omada's investors could've hoped for, given that many digital health startups now looking to IPO last raised at huge valuations during VC's ZIRP period. Those valuations could be difficult to realize in today's market. Hinge Health, for example, went public at a $2.6 billion valuation after being valued in its 2021 fundraise at $6.2 billion. We don't know what Omada Health's investors paid for their shares, so we can't calculate their profit. However, since Omada's shares opened on the stock market at $23, we used that price to determine the worth of its investors' stakes. None of Omada's major investors sold any shares in its IPO. Here's what the stakes of Omada Health's major investors and executives are worth after its IPO. Revelation Partners is a healthcare-focused investment firm that says it provides flexible capital to companies, especially to give liquidity to startups. The firm first invested in Omada in September 2019, according to its website. Revelation Partners told Business Insider in an email that the firm invested in Omada through a series of secondary transactions. Omada hasn't mentioned Revelation Partners in previous press releases about its fundraises. Revelation Partners owns about 5.2 million shares, or 9.3% of the company. At the $23 market debut price, the firm's stake is worth about $120 million. US Venture Partners, an investor: $108.5 million San Francisco-based US Venture Partners makes early-stage investments across healthcare, software, consumer, and security. The firm says it's invested $4.5 billion across 532 companies. USVP led Omada Health's $4.7 million Series A fundraise in 2013. The firm contributed additional financing in Omada's Series B through D rounds. General partner Dr. Jonathan Root has served on Omada's board of directors since the firm's 2013 investment. USVP owns about 4.72 million shares, or 8.5% of Omada Health. At the $23 market debut price, the firm's stake is worth about $108.5 million. Andreessen Horowitz, an investor: $106 million VC giant Andreessen Horowitz, or A16z, first invested in Omada Health in 2015, when the firm led Omada's $23 million Series B. The firm went on to invest in Omada's Series C and D fundraises, per PitchBook. At the time of A16z's 2015 investment, former general partner Balaji Srinivasan joined Omada's board of directors. It's unclear when he stepped down from the board; he moved into a part-time role at A16z that same year. A16z owns about 4.6 million shares, or 8.3% of the company. At the $23 market debut price, the firm's stake is worth about $106 million. Fidelity Management and Research Company, an investor: $102 million Fidelity Management and Research Company is the parent company of financial services giant Fidelity Investments. Fidelity has invested in a handful of healthcare startups over the years, leading rounds like now- public insurtech Oscar Health 's $400 million raise in 2016 and smart ring maker Oura 's $200 million Series D in December. FMR led Omada's $192 million Series E fundraise in February 2022. Fidelity owns about 4.4 million shares, or 8.0% of the company. At the $23 market debut price, the firm's stake is worth about $102 million. Cigna Ventures, an investor: $79 million Health insurance giant Cigna spun out a venture capital arm in 2018 to back healthcare companies. Omada Health was one of the firm's first bets. Cigna began working with the diabetes company in 2015. Two years later, the insurer announced an investment in Omada, leading a $50 million round in 2017 that Cigna Ventures later called Omada's Series C-1 financing. Cigna also expanded its partnership with Omada as part of its formal investment. Cigna Ventures owns about 3.4 million shares, or 6.2% of the company. At the $23 market debut price, the firm's stake is worth about $79 million. aMoon Fund, an investor: $62 million Israeli VC firm aMoon fund invests in healthcare and life sciences companies from early to late stages. Founded in 2016, it has backed a number of biotech companies that later went public, including Sophia Genetics, which went public in 2021, and Amylyx Pharmaceuticals, which went public in 2022. The firm first invested in Omada Health in its $192 million Series E round in 2022. "The entire space of all these clusters of diseases that includes diabetes, hypertension, and obesity is going through a major revolution right now," aMoon Fund managing partner Tomer Berkowitz told BI. "The solution in the end will not just be based on drugs, but it'll be a combination of drugs and behavioral change. I think Omada plays a significant role in that." aMoon owns about 2.7 million shares, or 4.9% of the company. At the $23 market debut price, the firm's stake is worth about $62 million. Norwest Venture Partners, an investor: $58 million San Francisco-based Norwest Venture Partners invests in early- to late-stage startups. It's backed more than 700 companies and manages over $15.5 billion in assets, per the firm. Its healthcare portfolio also includes hospital operations AI company Qventus, which raised $105 million in January led by private equity firm KKR, and behavioral health site Talkspace, which went public in a 2021 SPAC deal. The firm led Omada's $48 million Series C round in 2015 and put additional funding into Omada's Series C-1 and D rounds. Norwest owns about 2.5 million shares, or 4.5% of the company. At the $23 market debut price, the firm's stake is worth about $58 million. Sean Duffy, CEO: $46 million Sean Duffy cofounded Omada Health alongside Adrian James, Omada's former president, and Andrew DiMichele, former chief technology officer, in 2011. The startup sought to use technology to deliver care for chronic conditions, initially focusing on prediabetes, to patients in between visits with their primary care providers. Duffy and James spun Omada out of the design and consulting firm IDEO, where they'd begun researching the challenges in prediabetes and metabolic disease care. For Duffy, the IDEO gig had begun as an internship while he was getting dual MD-MBA degrees at Harvard. Instead of returning to complete his studies, he turned his focus to the idea that would become Omada. Before Omada, Duffy had created the interactive Microsoft Excel training tool Excel Everest, written about healthcare innovation for the medtech blog Medgadget, and worked in people analytics at Google. Duffy owns about 2 million shares, or 3.5% of Omada Health. That number includes about 860,000 shares of common stock and 1.15 million stock options exercisable by May 30, according to Omada's S-1 filing. At the $23 market debut price, his stake is worth about $46 million. Wei-Li Shao, president: $13 million Wei-Li Shao has served as Omada's president since 2021. He first joined the company in 2021 as its chief commercial officer. Before Omada, Li spent a combined 17 years at Eli Lilly managing a number of the pharma giant's businesses and brands, including its Alzheimer's disease, diabetes, and neurosciences businesses.

He'd previously led strategic finance efforts at primary care chain One Medical through its 2020 IPO. Before that, he spent six years in finance and strategy at Salesforce. Cook owns about 340,000 stock options exercisable by May 30, giving him less than 1% ownership. He does not own any shares of common stock. At the $23 market debut price, his stake is worth about $7.9 million. Trevor Fetter, board member: $5.3 million Trevor Fetter has served on Omada's board of directors since March 2021.
