Diet pills have been linked to heart problems, with some studies finding that they can increase the risk of heart attacks and other cardiovascular issues. While being overweight can increase the risk of heart disease, diet pills are not a silver bullet solution for weight loss. Some first-generation diet pills have been found to cause adverse effects on the heart, and certain pills have been removed from the market due to safety concerns. However, newer drugs may offer safer alternatives for treating obesity. It is important to consult a doctor or pharmacist when considering the use of diet pills, as certain pills may be associated with an increased risk of heart valve abnormalities and other heart problems.

What You'll Learn
First-generation diet pills and heart attack risks
Diet pills have been linked to heart problems, with some first-generation diet pills proving risky to the heart. Ponderax and Adifax, for example, have been associated with heart valve problems, even if taken for less than three months. However, the risk of serious problems is extremely low for most people, and those treated with Ponderax or Adifax for less than three months are not at a greater risk of heart valve abnormalities. Nevertheless, those treated for three months or more may have an increased risk, and it is recommended that they see a doctor for a heart examination.
Ponderax and Adifax are not the only diet pills associated with heart problems. A report by doctors at the Mayo Clinic and a clinic in Fargo, ND, found a very rare heart valve ailment in 24 previously healthy women taking a combination of fenfluramine and phentermine, or fen-phen. Eight of the women also experienced a potentially fatal constriction of the arteries to the lungs. While the FDA has approved each drug for use by itself for short periods to treat severe obesity, they have never approved this combination.
Some over-the-counter (OTC) appetite suppressants or weight-loss supplements have also been linked to reports of heart attack, seizure, stroke, and death. These often contain stimulants such as ephedra, ephedrine, or caffeine. It is important to consult a healthcare provider before taking any OTC diet pills or supplements, as they can interact with medications or cause health problems.
While diet pills may pose risks, it is important to note that obesity is also a serious health issue that increases the risk of premature death and various health problems, including heart attack and stroke. Therefore, it is crucial to carefully consider the benefits and risks of different treatment options with a healthcare provider before deciding on a course of action.

Fen-phen and heart valve issues
Diet pills have had a long history of causing heart problems. First-generation diet pills, in particular, have been associated with heart valve abnormalities. Ponderax and Adifax, for example, have been linked to an increased risk of heart valve issues when taken for three or more months.
Fen-phen, a combination of fenfluramine and phentermine, is another diet pill that has been associated with heart valve problems. In 1997, the Food and Drug Administration (FDA) warned doctors to monitor patients taking this pill combination for heart issues. This warning was issued in response to a report by doctors at the Mayo Clinic and a clinic in Fargo, ND, who found rare heart valve ailments in 24 previously healthy women taking the pills. The report also noted a potentially fatal constriction of the arteries in the lungs in eight of the affected women.
The "fen" part of fen-phen, or fenfluramine, was identified as the main culprit behind the heart valve damage. As a result, the drug was pulled from the market. A study published in the American Heart Association's journal Circulation shed light on the underlying mechanisms of how fen-phen damaged the heart. It was found that the activation of 5-HT2B receptors may be necessary for heart valve damage to occur.
The implications of this study are significant, as it highlights the need for all potential medications to be screened for their interaction with the 5-HT2B receptor before receiving approval. This precautionary measure could potentially prevent heart valve damage in those seeking weight loss solutions and ensure their safety.

Ponderax and Adifax: Risks and symptoms
Ponderax and Adifax are diet pills that were available only on prescription from 1966 to September 1997 and 1993 to September 1997, respectively. They are no longer available. These pills work by reducing appetite, which helps to reduce food intake and cut down on calories.
Ponderax and Adifax are associated with an increased risk of heart valve problems. Even if taken for a short period, these pills could have caused thickening of the heart valves in some people. This thickening can prevent the heart valves from closing properly, a condition known as mitral or aortic incompetence. In most cases, the thickening is mild and does not cause any health issues. However, those who have taken these pills for three months or more are advised to see a doctor for a heart examination and to discuss the risks. If you are experiencing any worrying symptoms, such as breathlessness, palpitations, or ankle swelling, it is recommended to see a doctor immediately.
Ponderax and Adifax can also cause other side effects. Ponderax may cause insomnia, dizziness, dry mouth, loss of appetite, and constipation. It may also be unsafe during pregnancy, as animal studies have shown harmful effects on the developing baby. Adifax may cause nausea, vomiting, stomach pain, heartburn, and diarrhea. Additionally, long-term use of Adifax can lead to kidney damage.
If you are unsure whether you have taken Ponderax or Adifax, a pharmacist or doctor may be able to help. It is important to inform your dentist or surgeon if you have taken these pills before undergoing any dental or surgical procedures. This is because people with thickened heart valves may need to take antibiotics beforehand to prevent infections on the heart valves.

FDA-approved diet pills
Diet pills have been linked to heart problems in the past. Ponderax and Adifax, for example, have been associated with heart valve problems, and some first-generation diet pills have been deemed risky for the heart. However, there are a number of FDA-approved diet pills on the market that have been deemed safe when used as instructed.
The FDA has approved eight weight-loss drugs, which are typically prescribed to patients with a BMI of 27 or higher who also have an additional medical condition such as high blood pressure, type 2 diabetes, or high cholesterol. These medications are intended to be used in conjunction with a healthy diet and exercise regime and should be recommended by a healthcare provider.
- Orlistat (Xenical, Alli): This medication belongs to a class of drugs called lipase inhibitors, which reduce the amount of fat absorbed in the gut after eating. The recommended dosage is 120 mg, three times daily, and no more than 30% of your calories should come from fat while taking this medication.
- Liraglutide (Saxenda), Victoza: This medication is approved for use in adolescents and young adults who have not achieved expected weight loss from surgery, patients with obesity and binge-eating disorder, and women with obesity and polycystic ovary syndrome.
- Phentermine-topiramate (Qsymia): This medication is approved for long-term use and is one of six drugs approved for adults and children ages 12 and older.
- Naltrexone-bupropion (Contrave): This is a combination medication that includes an antidepressant and an opioid antagonist. It is typically taken differently each week for the first month, following a dosing schedule prescribed by a healthcare provider.
- Tirzepatide (Zepbound): This medication is injected subcutaneously and is approved for adults with obesity. The recommended dosage is 5-15 mg, injected once weekly.
- Setmelanotide (IMCIVREE): This medication is approved for children ages 6 and older with rare genetic disorders causing obesity.
It is important to note that medications are not a replacement for physical activity and healthy eating habits. They can, however, help with hunger, cravings, and metabolic preservation when used in conjunction with a healthy lifestyle. It is also important to consult a healthcare professional before taking any medication to ensure it is safe and appropriate for your individual needs.

Lisdexamfetamine: Pros and cons
Diet pills have been linked to heart problems. Ponderax and Adifax, for example, have been associated with heart valve problems. In 1997, a report by doctors at the Mayo Clinic and Fargo, ND, clinic found a rare heart valve ailment in 24 previously healthy women who were taking fenfluramine and phentermine, or fen-phen.
Lisdexamfetamine is a stimulant medication used to treat attention deficit hyperactivity disorder (ADHD) in children and adults, as well as moderate-to-severe binge eating disorder in adults. It is also used to treat narcolepsy. It is taken orally, and its effects generally begin within 90 minutes and last for up to 14 hours. It is important to note that lisdexamfetamine is not to be used for obesity or weight loss.
Pros
Lisdexamfetamine is the only USFDA- and TGA-approved pharmacotherapy for binge eating disorder (BED). Clinical studies have shown that it is effective in treating ADHD in adults and children, with improvements in attention observed within 2 hours of taking a dose. It is also considered the most effective treatment for adult ADHD. For binge eating disorder, lisdexamfetamine has been shown to significantly reduce the number of binge eating days and episodes per week. It is also superior to a placebo in several secondary outcome measures.
Cons
Lisdexamfetamine has a high potential for substance abuse and can be habit-forming. It may cause sudden death in children and teenagers, especially those with heart defects or serious heart problems. It may also cause sudden death, heart attack, or stroke in adults, especially those with underlying heart problems. Other serious side effects include mania, psychosis, serotonin syndrome, and allergic reactions. It is not recommended for use during pregnancy or breastfeeding, as it may harm the baby.
