Prescription diet pills are medications that can be used to treat obesity and health problems related to being overweight. They are generally only approved for and prescribed to patients with a body mass index (BMI) of 30 or higher, or those with a BMI of 27 and above who have weight-related health conditions such as diabetes or high blood pressure. While these pills can be effective in helping people lose weight, they also come with side effects, and safety has been a concern in the past.

What You'll Learn
Effectiveness and safety concerns
Prescription weight loss medications work in a variety of ways, and their effectiveness varies from person to person. Some common prescription weight loss drugs include Wegovy, Zepbound, Saxenda, and Qsymia. These medications often come with side effects, which are usually digestive issues. Other potential side effects can be more serious, and in some cases, the side effects of prescription medications may outweigh the benefits. For this reason, it is important to consult a doctor about any side effects or new conditions observed after beginning a medication. Furthermore, certain compounded medications have not been reviewed by the FDA, so it is important to discuss any concerns about a prescription with a healthcare provider.
Prescription weight loss medications are generally only approved for and prescribed to patients with a body mass index (BMI) of 30 or higher. They may also be prescribed to patients with a BMI of at least 27 who have weight-related health conditions, such as diabetes or high blood pressure. These medications are intended to be used in conjunction with a reduced-calorie eating plan and an exercise program. According to the National Institute of Diabetes and Digestive and Kidney Diseases, people who take prescription weight loss drugs in addition to following a program of exercise and healthy eating lose 3%-12% more of their starting weight than those who make lifestyle changes alone.
The history of weight loss pills is complicated, and safety has previously been an issue. The FDA has banned or withdrawn several early iterations of weight loss pills due to serious safety concerns. As a result, the FDA imposed guidance in the late 1990s to ensure more rigorous testing and review of weight loss medications, reducing safety concerns. However, the effectiveness of these pills was still lacking, with medications only helping people lose about 4% to 5% of their body weight.
The newer generation of weight loss pills is considered more effective, with some medications leading to weight loss of 10%-15%. However, it is important to note that these medications are not a magic bullet and must be accompanied by dietary changes and increased physical activity to be effective. Furthermore, weight loss medications are not a long-term solution, as stopping the medication will likely result in weight regain. Therefore, it is crucial to develop other healthy habits alongside taking the medication to maintain weight loss.

Side effects
While prescription diet pills can be effective in helping people lose weight, they can also have side effects, some of which may be severe. It's important to consult a healthcare professional before taking any medication to treat obesity and to be aware of the possible risks and benefits.
Some prescription weight loss medications have been associated with severe side effects, including rare cases of severe liver injury and an increased risk of eating disorders. Diet pills often contain a blend of stimulants, herbs, and other ingredients that can cause toxicity and adverse reactions when interacting with other medications. People taking certain weight-loss medications have also reported having suicidal thoughts or actions.
Gastrointestinal problems are a common side effect of some prescription diet pills, such as Wegovy, which can slow down people's digestive systems. During clinical trials of Wegovy, some participants experienced nausea, diarrhea, vomiting, constipation, abdominal pain, headache, fatigue, indigestion, dizziness, bloating, and gas. Orlistat, another prescription weight loss medication, can also cause gastrointestinal issues, especially when consuming high-fat foods. It can also interfere with the absorption of vitamins A, D, E, and K, so it's important to take a multivitamin at least two hours before or after taking Orlistat.
Other prescription diet pills, such as Phentermine, are controlled substances due to their potential for addiction and abuse. These medications are typically approved for short-term use and should be used with caution if there is a history of substance use disorder.
It's important to note that weight loss medications are not a substitute for a healthy lifestyle. Even with prescription diet pills, weight loss usually requires a combination of reduced-calorie eating plans and regular physical activity. Additionally, maintaining weight loss often requires continued medication, and stopping the medication may result in weight gain.

Weight loss drugs and pregnancy
Weight loss drugs may be an option for individuals with obesity, defined as a body mass index (BMI) of 30 or higher, or a BMI of at least 27 with weight-related health conditions such as diabetes or high blood pressure. These drugs are intended to be used alongside a reduced-calorie diet and exercise program. While they can be effective, they often come with side effects, and it is important to consult a healthcare professional before taking them.
When it comes to pregnancy, the current recommendation is that weight loss drugs should be discontinued at least two months before becoming pregnant. This is because all weight loss drugs currently on the market are contraindicated during pregnancy, meaning they are not recommended due to potential risks. For example, phentermine has been associated with fetal stroke. Additionally, some weight loss drugs may interfere with the effectiveness of hormonal birth control methods, increasing the chances of unplanned pregnancies.
If a surprise pregnancy occurs while taking weight loss medication, it is crucial to immediately stop the medication and consult a healthcare provider. The sudden discontinuation of weight loss drugs can lead to intense withdrawal symptoms, including rapid weight regain. However, the potential risks to the developing fetus may outweigh these concerns.
While weight loss drugs themselves are not recommended during pregnancy, treating obesity through diet and exercise during pregnancy is associated with improved outcomes. A 2012 study published in the British Medical Journal found that these interventions significantly reduced the risk of preeclampsia and gestational diabetes. Therefore, it is essential to prioritize lifestyle changes over medication use during pregnancy.
In summary, while weight loss drugs can be effective for individuals struggling with obesity, they should be discontinued before becoming pregnant. Pregnancy and the postpartum period can present unique challenges for individuals with weight concerns, and it is important to work closely with healthcare professionals to ensure the safety and well-being of both mother and child.

Weight loss drugs for minors
Weight loss drugs are a popular and effective treatment for obesity and related health problems. Doctors may prescribe these medications to patients with a body mass index (BMI) of 30 or higher. They may also be prescribed to patients with a lower BMI if they have weight-related health conditions, such as diabetes or high blood pressure.
In recent years, obesity rates have risen among children and adolescents in the US, affecting nearly 1 in 5 individuals between the ages of 2 and 19. To address this issue, the American Academy of Pediatrics (AAP) has included anti-obesity medications in its guidelines for treating childhood obesity. According to these guidelines, doctors should offer weight loss drugs to children with obesity aged 12 and above. However, experts emphasize that there is no magic age or weight for a child to start taking weight loss drugs. The decision should be based on the severity of the case and the impact of a child's weight on their overall health.
Several weight loss drugs have been approved for use in adolescents as young as 12, including Wegovy, Saxenda, orlistat, and Qsymia. Wegovy and Saxenda are GLP-1 agonists, a newer class of drugs that has gained popularity for their effectiveness in weight loss. Liraglutide and semaglutide, which are sold under the brand name Wegovy, are injection medications that slow digestion and increase insulin release, resulting in reduced food cravings and increased feelings of fullness. Orlistat, another option for teens, works by blocking fat absorption, causing it to exit the body through waste. However, it may not lead to significant weight loss and can cause side effects such as stomach pain, bloating, and indigestion.
While weight loss drugs can be effective, they often come with drawbacks. They tend to be expensive and may not be covered by insurance. Additionally, there are concerns about the unknown long-term effects of starting these medications at a young age. Some weight loss drugs, such as those containing phentermine, carry risks of addiction or abuse and are classified as controlled substances. Furthermore, certain medications can cause unpleasant or serious side effects, and their effectiveness may diminish over time, leading to potential weight regain.
It is important to note that behavioural and lifestyle modifications, such as diet and exercise, are still considered the first line of treatment for minors struggling with weight issues. Weight loss drugs should be viewed as a supplementary option when other approaches have proven insufficient. Before prescribing any medication to minors, physicians must carefully consider the potential benefits, risks, and long-term implications.

Weight loss drugs and addiction
Weight loss drugs are a popular and effective treatment for obesity and related health problems, such as high blood pressure or diabetes. They are intended to be used in conjunction with a healthy diet and exercise program. While some people have been helped by weight loss drugs in the short term, the weight tends to return, and they can come with several side effects.
One class of weight loss drugs, called GLP-1 receptor agonist drugs, has been found to have potential benefits in treating addiction. GLP-1 receptor agonists are approved for use in diabetes and weight loss, but researchers have found that they may also help with other conditions, including cardiovascular disease and addiction. These drugs replicate the effects of the hormone glucagon-like peptide-1 (GLP-1), which stimulates the release of insulin and triggers other beneficial responses. Several structures in the brain also produce GLP-1 or carry receptors for the hormone, including areas involved in our reward pathways, which drive us to pursue pleasurable activities.
Addiction involves "hijacking the brain's reward pathways," according to behavioral neuroscientist Patricia Grigson. Researchers believe that GLP-1 analogs may reduce addictive behaviour by quelling activity in this system. Patients taking GLP-1 analogs for diabetes or weight loss have reported reduced cravings for substances such as alcohol, nicotine, and even cocaine. Studies have found that these patients exhibited a 50% lower rate of alcohol intoxication and a decreased risk of opioid overdose.
While these findings are promising, more research is needed to validate these results and understand the underlying mechanisms. It is also important to note that not all weight loss drugs are created equal, and some, such as phentermine, carry a risk of addiction or abuse themselves. These stimulant drugs are classified as "controlled substances" and require a special type of prescription.
