What to know about Ozempic: Diabetes drug used off-label for weight loss sparks warnings
KUALA LUMPUR, June 11 — As global interest in weight loss remedies grows, the off-label use of diabetes medication Ozempic for shedding pounds in non-diabetic individuals has emerged as a trend.
This rising popularity, fuelled by social media and anecdotal success stories, has prompted medical professionals to caution against its unsupervised use.
Here's what you need to know about Ozempic, its side effects, and why expert supervision is essential before considering it for weight loss.
What is Ozempic?
Ozempic is a medication primarily approved for managing type 2 diabetes. Its active ingredient, semaglutide, mimics a hormone that targets areas of the brain involved in appetite regulation.
Initially designed for diabetes treatment, Ozempic has gained popularity as a weight loss aid, even among non-diabetic individuals.
Can Ozempic be used for weight loss?
According to Universiti Teknologi MARA consultant endocrinologist Prof Dr Rohana Abdul Ghani, Ozempic is not intended for use as a weight loss medication for non-diabetic patients.
'Ozempic is approved in Malaysia specifically for managing type 2 diabetes. However, semaglutide's weight loss benefits have led some to seek it off-label for obesity treatment,' she said.
For non-diabetic patients, semaglutide should be administered at a higher dose of 2.4mg weekly under another brand name, which is unavailable in Malaysia, she added.
'The off-label use of Ozempic among non-diabetic patients has led to a shortage for those with type 2 diabetes and reduced efficacy due to the lower dose,' said Dr Rohana.
She also highlighted studies suggesting that regular use of weight loss drugs might establish a 'new normal' in the body, potentially leading to weight gain. One study in the New England Journal of Medicine found that low doses of semaglutide (between 0.25mg and 0.5mg) were linked to weight gain in some patients.
What are the potential side effects?
As with any medication, Ozempic comes with potential side effects.
Dr Rohana said common gastrointestinal side effects include nausea, vomiting, constipation, or diarrhoea, which are typically self-limiting and subside within one to two weeks.
She added that rare side effects include skin reactions at the injection site and worsening eyesight, particularly in patients with high blood sugar experiencing rapid improvement.
'Ozempic should not be used by patients with a history of thyroid cancer due to the rare risk of pancreatitis,' she said.
Who shouldn't take Ozempic without medical advice?
Dr Rohana stressed that no one should take Ozempic without consulting a doctor.
'Medications like Ozempic for obesity should be paired with proper diet and lifestyle changes. Without these, there's a risk of complications such as significant muscle mass loss or kidney issues from severe vomiting,' she said.
'These medications should only be prescribed by clinicians who are familiar with their effects and risks,' she added.

Covid-19: Health Ministry urges high-risk groups to get vaccinated amid JN.1 subvariant spread
KUCHING, June 12 —The Ministry of Health (MoH) has assured the public that the JN.1 Covid-19 subvariant, which has been spreading recently, is not as dangerous as the variants that circulated during the pandemic period. The ministry also stated that although there has been a recent increase in Covid-19 cases nationwide, the average weekly number of cases remains below the national warning threshold, and no deaths have been reported so far. In a statement today, MoH highlighted that Covid-19 infections can be effectively controlled by maintaining a strong level of immunity. As such, the ministry encourages individuals in high-risk groups to receive an additional dose of the Covid-19 vaccine to reduce the risk of infection, serious complications, and death. 'The administration of the Covid-19 vaccine is encouraged for high-risk groups consisting of individuals who have not received the vaccine before,' said the ministry, adding that even those who had previously been vaccinated are encouraged to go for another round. High-risk groups include individuals aged 18 years and above as well as individuals aged 12 years and above, who have comorbidities or are immunocompromised, pregnant women and healthcare workers, especially those who have direct contact with patients. MoH said the Covid-19 vaccine is given voluntarily and free of charge at selected government health clinics nationwide, which can be looked up at website and the MySejahtera application. The public is also advised to continue observing standard Covid-19 prevention measures, such as washing hands regularly with soap or hand sanitiser, practising proper cough etiquette, and wearing a face mask when symptomatic or in crowded places. 'The MoH remains committed to ensuring that community health is given priority and that health services and control of the spread of any epidemic are at the best level,' it added. — The Borneo Post

Woman pleads not guilty to running illegal dental clinic in Melaka
Nur Shafikah Razali faces two charges of opening an unregistered private dental clinic and practising dentistry without being registered. (Freepik pic) PETALING JAYA : A woman burst into tears at the Melaka sessions court today after being charged with running an unregistered clinic and practising dentistry illegally since last year. Nur Shafikah Razali, 26, pleaded not guilty when the two charges were read to her before judge Haderiah Siri. She was charged with opening an unregistered private dental clinic under Section 27 of the Private Healthcare Facilities and Services Act 1998, an offence allegedly committed at 8.25pm on Nov 4, 2024 at a house on Jalan Seri Duyong 2/3 in Taman Seri Duyong 2, Melaka Tengah. She was also charged under Section 62(1) of the Dental Act 2018 with practising dentistry without being registered, punishable under Section 62(3) of the same Act, at the same place and time. Health ministry prosecuting officer Khadijah Wahab proposed bail of RM10,000 for both charges, and the additional condition that Shafikah be required to report to a police station once a month. In pleading for a lower bail, Shafikah, who was unrepresented, said she only had RM2,500 because she was unemployed and that she was suffering from serious pregnancy sickness. The court set bail at RM4,000 in one surety, allowed the condition requested by the prosecution, and set July 23 for re-mention of the case.

Traces of insecticides detected in rainwater in Japan
Japanese researchers say certain insecticides are also present in rainwater. (Envato Elements pic) PARIS : Pesticides don't just contaminate the air humans breathe or the food they eat. According to recent research conducted in Japan, certain insecticides are also present in rainwater. Scientists at Japan's University of Tokyo recently made a worrying discovery. Residues of several insecticides belonging to the well-known neonicotinoid family have been detected in rainwater. In Japan, neonicotinoids were introduced on a large scale in the 1990s, particularly in rice fields and pine forests. To reach this conclusion, the scientists collected and analysed rainwater samples from the cities of Tsukuba and Kashiwa, both located northeast of Tokyo. Their analyses were carried out between April 2023 and September 2024. They reveal that 91% of samples contained several insecticides from the neonicotinoid family. The highest total concentration was detected in August 2024, the study authors note. Acetamiprid is the predominant insecticide, having been identified in 82% of samples, followed by thiacloprid (73%) and dinotefuran (45%), two other insecticides from the neonicotinoid family. 'This research is the first report on neonicotinoid presence in precipitation, suggesting that neonicotinoids, as low volatile matter, can still be dispersed to the environment via precipitation,' warned the researchers, whose work is published in the journal Environmental Monitoring and Contaminants Research. Potential effects on human health In 2019, another study (also conducted by researchers at the University of Tokyo), published in the journal Science, explained in detail how the large-scale use of neonicotinoids contributed to the destruction of several species of fish, crustaceans, and zooplankton in Lake Shinji (southwestern Japan). Starting in 1993, several rice farmers began spraying imidacloprid on their fields. According to the study, the introduction of this insecticide in areas geographically close to the lake coincided with an 83% decrease in the average zooplankton biomass. While the harmful effects of neonicotinoids on insects (particularly bees) and several other animal species are increasingly well documented, doubts remain about their impact on human health. Given that neonicotinoids target the nervous system, scientists fear (among other things) that exposure to these substances may be linked to neurological disorders. However, these risks remain uncertain at present due to a lack of large-scale studies on the subject.
