Diet pills and weight loss supplements are designed to help people lose weight. However, they often come with a range of side effects, including jitteriness, shakiness, headaches, insomnia, increased blood pressure, and heart rate. This is because many weight loss supplements are amphetamines or amphetamine derivatives, which stimulate the body to burn fat. While these drugs can be effective in spurring weight loss, they can also cause negative side effects, especially if combined with other supplements. It is important to use these supplements in moderation and alongside a low-calorie diet and doctor-approved exercise plan to minimize potential health risks.

What You'll Learn
Weight loss supplements are amphetamines or amphetamine derivatives
Weight loss supplements are known to have side effects, and one of the most common is feeling jittery or shaky. While these supplements are meant to aid weight loss, they can often contain amphetamines or amphetamine derivatives, which are stimulants that increase your metabolism and encourage your body to burn stored fat for energy. Amphetamines can make people feel energised, but they also carry serious risks, including addiction and an increased risk of stroke.
Some weight loss supplements contain unnatural compounds, such as beta-methylphenethylamine, which is structurally similar to amphetamine. This compound has not been tested on humans, but animal studies suggest it may behave similarly to amphetamine and could pose a public health risk. Manufacturers may use ingredients like Acacia rigidula as a cover for introducing new synthetic drugs similar to amphetamine.
Amphetamines and their derivatives can be identified in weight loss pills and dietary supplements through capillary electrophoresis-tandem mass spectrometry (CE-MS/MS). This method can simultaneously determine amphetamine and its derivatives, providing efficient separation of isomers with high sensitivity. The process involves a modified QuEChERS extraction procedure at a high pH, followed by electrophoretic separation and detection.
It is important to note that weight loss supplements are not miracle pills and should be used in moderation alongside a healthy diet and exercise. Most active ingredients in supplements are safer in small doses, and combining multiple supplements can be dangerous. Always consult a healthcare professional before taking any weight loss supplements, especially if you have a substance use disorder or family history of such disorders.

Side effects of weight loss drugs
Weight loss drugs and supplements can have various side effects, and it is important to be aware of these before taking them. Firstly, it should be noted that weight loss supplements are not 'miracle pills', and should be used in conjunction with a healthy diet and exercise. They can provide an extra boost to your weight loss journey, but they are not a substitute for a healthy lifestyle.
Stimulant-type weight loss drugs, such as phentermine, diethylpropion, and amphetamines, can lead to insomnia, increased blood pressure, a fast heart rate, restlessness, drug dependence, abuse, and withdrawal symptoms. These drugs are usually recommended for short-term use (up to 12 weeks) to avoid dependence and other side effects. Phentermine, in particular, has been known to cause overstimulation, high blood pressure, insomnia, rapid or irregular heart rate, and tremors. It is not suitable for those with hyperthyroidism, glaucoma, or heart disease, or for those who have had a stroke.
Drugs that interfere with fat absorption, such as orlistat (also known as alli or Xenical), can lead to oily spotting, gas, and soft stools. Orlistat can be used for longer-term weight loss and maintenance. Diet pills that affect neurotransmitters in the brain, such as bupropion and naltrexone (Contrave), can cause headaches, dry mouth, dizziness, nausea, vomiting, and constipation.
GLP-1 receptor agonists, such as liraglutide and semaglutide, and GIP and GLP-1 receptor agonists, such as tirzepatide, can cause stomach problems like nausea, vomiting, diarrhea, constipation, stomach pain, heartburn, and gas. A 2023 analysis found that 4.5% of users stopped taking these drugs due to side effects, with 44% experiencing nausea and 30% experiencing diarrhea. These drugs are usually prescribed for adults or children aged 12 and above with a BMI of 30 or greater, or a BMI of 27 or greater with comorbidities such as high blood pressure, diabetes, or high cholesterol.

Appetite suppressants
Diet pills, or weight loss supplements, often cause side effects such as jitters or shakes. This is because many weight loss supplements are amphetamines or amphetamine derivatives, which are stimulants that increase metabolism and encourage the body to burn stored fat for energy. While these stimulants can provide increased energy at low doses, higher doses may lead to jitters and other negative side effects.
There are both prescription and over-the-counter (OTC) appetite suppressants available. Prescription appetite suppressants can be used for short-term or long-term weight loss goals. It is crucial to consult a healthcare professional before taking any medication, including OTC appetite suppressants, as they may interact with other medications or cause health problems.
Some common prescription appetite suppressants include:
- Liraglutide (Saxenda) - a subcutaneous injection medication
- Semaglutide (Wegovy) - a subcutaneous injection medication
- Naltrexone-bupropion (Contrave) - a pill
- Phentermine-topiramate (Qsymia)
- Benzphetamine (Didrex, Regimex) - short-term use only
- Diethylpropion (Tenuate, Tenuate Dospan) - short-term use only
- Phendimetrazine (Prelu-2) - short-term use only
- Phentermine (Adipex-P, Dipex-P, Atti-Plex P, Pro-Fast) - short-term use only
These medications may have side effects, including stomach issues (nausea, vomiting, diarrhea, constipation, stomach pain), insomnia, increased blood pressure, fast heart rate, restlessness, drug dependence, abuse, withdrawal symptoms, headache, dry mouth, and dizziness. It is important to discuss potential side effects with a healthcare provider before starting any medication.

Combining diet pills with other medications
Diet pills, also known as weight loss supplements, can cause jitters as a side effect. This is because they often contain amphetamines or amphetamine derivatives that increase your metabolism and stimulate your body to burn fat. While these substances can aid weight loss, they can also lead to negative side effects such as jitters or shakes.
Some specific examples of how combining diet pills with other medications can be harmful include:
- St. John's Wort, an herbal supplement, can reduce the effectiveness of drugs for HIV/AIDS, heart disease, depression, organ transplants, and birth control pills.
- Warfarin (a blood thinner), ginkgo biloba (an herbal supplement), aspirin, and vitamin E can all thin the blood, so taking them together may increase the risk of internal bleeding or stroke.
- Alcohol can increase or decrease the effects of certain medications and may lead to symptoms like headaches, nausea, drowsiness, and loss of coordination. Mixing alcohol with certain medications can increase the risk of internal bleeding and cause issues with the liver, heart, and lungs.
- Decongestants may interfere with the effectiveness of medications or raise blood pressure.
- Nicotine replacement products can interact with prescription drugs for depression, asthma, or smoking cessation, so it is important to consult a healthcare professional before using them concurrently.
It is important to note that dietary supplements may contain ingredients that can have strong effects on the body, and their manufacturers are responsible for ensuring their safety. Combining multiple supplements or high doses can be dangerous, and supplements should always be used in conjunction with a healthy diet and exercise rather than as a sole means of weight loss.

Weight regain after stopping weight loss drugs
Many weight loss supplements contain amphetamines or amphetamine derivatives, which are stimulants that increase your metabolism and encourage your body to burn stored fat for energy. While these can be effective in spurring weight loss, they often come with side effects such as jitters or shakes. These side effects can be unpleasant and difficult to deal with, leaving you with the tough question of whether to continue taking the supplements despite the side effects or to stop taking them to regain your health.
When it comes to weight loss drugs, it is important to understand the potential for weight regain after stopping their use. While weight loss medications can be effective in helping individuals lose weight, it is common for some weight gain to occur after discontinuing the drugs. The amount of weight regained can vary from person to person, and it is not always possible to predict how much weight will be gained.
There are several reasons why weight regain may occur after stopping weight loss drugs. One reason is that the drugs may have helped to suppress appetite and control cravings while they were being taken. Once the drugs are stopped, the appetite and cravings may return, leading to increased calorie consumption. Additionally, some weight loss drugs work by increasing metabolism, and when the drugs are discontinued, the metabolism may slow down, resulting in reduced calorie burning.
Another factor contributing to weight regain is the potential dysregulation of brain regions related to appetite even after stopping the medication. This dysregulation can prime individuals to overconsume food, leading to weight regain. Furthermore, for individuals with health conditions such as type 2 diabetes, stopping weight loss medications may require close monitoring to ensure controlled blood sugar levels, which can impact weight management.
To reduce the risk of weight regain after stopping weight loss drugs, experts recommend making healthy lifestyle changes, such as adopting a balanced diet and engaging in regular exercise. These behavioral modifications can help individuals maintain their weight loss progress even after discontinuing the medications. Additionally, it is important to manage expectations and understand that weight regain is likely, even with the best efforts. Seeking guidance from healthcare professionals can help individuals navigate this challenging aspect of weight management.
