Sibutramine is a weight loss drug that was previously sold under the brand name Meridia. It is a serotonin-norepinephrine reuptake inhibitor (SNRI) that works by suppressing appetite and altering neurotransmitters in the brain. While it was once widely marketed and prescribed as an adjunct in the treatment of obesity, it has since been discontinued in many countries due to safety concerns and an increased risk of cardiovascular events, including heart attack and stroke. Despite this, sibutramine continues to be found in some dietary supplements and has been sold illegally in certain countries.

What You'll Learn
Sibutramine is a weight-loss drug
Sibutramine was initially developed in 1988 and was widely marketed and prescribed as an adjunct in the treatment of obesity, along with diet and exercise. It was recommended for obese patients with a body mass index (BMI) of 30 kg/m2 or higher, or a BMI of 27 kg/m2 or more in the presence of other risk factors such as diabetes or high cholesterol. The drug was typically taken once daily, with a starting dose of 10 mg per day, which could be increased to 15 mg after several weeks to achieve the desired weight loss results.
However, sibutramine has been associated with several adverse effects, including headache, dizziness, constipation, nausea, dry mouth, and insomnia. More seriously, it has also been linked to an increased risk of cardiovascular events, including heart attack and stroke, leading to its withdrawal from the market in several countries, including the United States, Canada, Europe, and Australia, in 2010. Despite this, sibutramine remains available in some countries, and it has been found in illegal weight loss products and dietary supplements, often undeclared or at higher-than-recommended doses.
It is important to note that sibutramine should not be taken without medical supervision. Individuals considering sibutramine for weight loss should consult their doctor to assess their suitability for the drug and monitor for any potential side effects.

It is an appetite suppressant
Sibutramine is a weight-loss drug that was formerly sold under the brand name Meridia, among others. It is a serotonin-norepinephrine reuptake inhibitor (SNRI) that works by blocking the reuptake of the neurotransmitters dopamine, norepinephrine, and serotonin. Blocking the reuptake of these neurotransmitters alters the balance of chemicals within the nerve cells, thereby affecting nerve function and interaction.
As an appetite suppressant, sibutramine helps to reduce hunger and cravings by increasing feelings of fullness and satisfaction after eating. It is recommended for obese patients with an initial body mass index (BMI) of 30 kg/m2 or higher, or a BMI of 27 kg/m2 or more in the presence of other risk factors such as type 2 diabetes, high cholesterol, or controlled hypertension.
The drug is typically taken once daily, preferably in the morning, and can be taken with or without food. The initial dosage is usually 10 mg per day, which may be increased to 15 mg after several weeks to achieve the desired weight loss results. It is important to note that sibutramine should be used in conjunction with a reduced-calorie diet and regular exercise for effective and sustainable weight loss.
While sibutramine can be an effective tool for weight management, it is not suitable for everyone. It is important to consult a doctor before taking sibutramine, especially for individuals with certain medical conditions, such as high blood pressure, liver or kidney disease, depression, or a history of heart problems. Additionally, sibutramine may interact with other medications, including antidepressants, cold or allergy medications, and diet pills, so it is crucial to disclose all medications being taken to a doctor.
In terms of side effects, sibutramine may cause an increase in blood pressure and heart rate, so regular monitoring is necessary, especially for individuals who are already obese and hypertensive. Other commonly reported adverse effects include headache, constipation, nausea, dizziness, dry mouth, and insomnia.
It is worth noting that sibutramine has been discontinued in many countries, including the United States, due to safety concerns and an increased risk of cardiovascular events, such as heart attacks and strokes. However, it may still be available in some countries, and it continues to be found in some dietary supplements marketed as "natural" or "herbal remedies," often without being listed on the product label.

It is a serotonin-norepinephrine reuptake inhibitor
Sibutramine is a weight-loss drug that was previously sold under the brand name Meridia, among others. It is a serotonin-norepinephrine reuptake inhibitor (SNRI) that works similarly to certain antidepressants. Serotonin-norepinephrine reuptake inhibitors are a class of drugs that block the reuptake of serotonin and norepinephrine, which are neurotransmitters that play a crucial role in regulating mood, appetite, and other functions. By inhibiting the reuptake of these neurotransmitters, sibutramine increases their levels in the brain, leading to reduced appetite and weight loss.
As a serotonin-norepinephrine reuptake inhibitor, sibutramine has been shown to be effective in inducing weight loss. In a clinical trial, participants taking sibutramine experienced a dose-related decrease in body weight, with weight loss of up to 11% when combined with a low-calorie diet. Over a one-year period, patients lost up to 15% of their body weight. Additionally, biochemical risk factors associated with obesity improved with sibutramine therapy.
However, as with any drug, there are potential side effects and risks associated with sibutramine. The most commonly reported adverse effects include headache, constipation, and nausea. Nervous system-related side effects, such as dizziness, dry mouth, and insomnia, were reported by more than 5% of patients. It is important to note that sibutramine can also cause an increase in blood pressure and heart rate, which requires regular monitoring, especially in obese hypertensive patients.
In 2010, sibutramine was voluntarily withdrawn from the US market by the manufacturer due to clinical trial data indicating an increased risk of heart attack and stroke. It has since been discontinued in many countries, including Australia, Canada, China, the European Union, and the United Kingdom. Despite this, sibutramine remains available in some countries, and it has been found in illegal weight loss products and dietary supplements marketed as "natural" or "herbal remedies".
It is important to consult a healthcare professional before taking any weight-loss medication, including sibutramine. The potential benefits and risks should be carefully considered, and individuals should follow the advice and recommendations of their healthcare provider.

It was withdrawn from the US market in 2010
Sibutramine, formerly sold under the brand name Meridia, is a weight-loss drug. It is an appetite suppressant that works as a serotonin-norepinephrine reuptake inhibitor (SNRI), similar to certain antidepressants. It was widely marketed and prescribed as an adjunct in the treatment of obesity alongside diet and exercise.
Withdrawal from the US Market in 2010
Sibutramine was voluntarily withdrawn from the US market by its manufacturer, Abbott Laboratories, in October 2010. The decision was made under pressure from the Food and Drug Administration (FDA), which had evaluated clinical trial data pointing to an increased risk of heart attack and stroke in patients with a history of cardiovascular disease. The SCOUT study, which informed the FDA's decision, showed a 16% increased risk relative to a placebo for serious cardiovascular events, including nonfatal myocardial infarction, nonfatal stroke, the need for resuscitation after cardiac arrest, and cardiovascular death.
The FDA's concerns about the drug's unnecessary cardiovascular risks were underscored by the fact that it only offered minimal efficacy and modest weight loss benefits to patients. Dr John Jenkins, director of the FDA's office of new drugs, stated that:
> Meridia’s continued availability is not justified when you compare the very modest weight loss that people achieve on this drug to their risk of heart attack or stroke.
The withdrawal of Meridia was a setback in efforts to provide a safe medicine to treat obesity, which remains one of the largest health problems in the US. Abbott Laboratories also withdrew the drug from the Canadian market and was in discussions with regulators in other countries.

It was found in some natural diet supplements in 2018
Sibutramine is a weight-loss drug that was approved by the US Food and Drug Administration (FDA) in 1997. It was originally developed in 1988 and was sold under brand names such as Reductil, Meridia, Siredia, and Sibutrex. The drug works by suppressing appetite and altering neurotransmitters in the brain. However, it has been associated with several serious side effects, including increased blood pressure and heart rate, cardiac arrhythmias, and mental health issues.
In 2018, the FDA found that sibutramine was still present in over 700 diet supplements marketed as "natural", "traditional", or "herbal remedies". This discovery highlighted the ongoing issue of unregulated herbal supplements, which can pose serious health risks to unsuspecting consumers. The FDA's finding in 2018 was not an isolated incident; there have been multiple reports of sibutramine being found in natural diet supplements over the years. For example, in 2009, the FDA recalled 34 products due to the presence of sibutramine, and in 2010, Health Canada warned the public about an illegal "Herbal Diet Natural" product that contained sibutramine without listing it as an ingredient.
The issue of sibutramine-laced natural diet supplements is particularly concerning because it can lead to accidental poisoning. In one study, researchers identified 17 cases of poisoning linked to a single product claimed to be of purely herbal origin. The manifestations of poisoning included malaise, tachycardia, headache, agitation, arterial hypertension, nausea, vomiting, dyspnea, insomnia, left-sided chest pressure, elevated temperature, and, in two cases, psychosis.
The presence of sibutramine in natural diet supplements is often not declared or adequately labelled, which can put consumers at risk, especially those with underlying medical conditions or incompatibilities with the drug. This issue is exacerbated by the growing market for dietary supplements and the ease of purchasing these products online from international suppliers.
To protect consumers, it is essential to ensure that all dietary supplement products declare their ingredients accurately and comprehensively. Additionally, consumers should be cautious when purchasing natural diet supplements and should always consult a healthcare professional before taking any new supplements, especially if they have any pre-existing health conditions.
