While some of these pills are relatively safe when used as directed, some diet pills and weight loss supplements should be avoided at all costs. Here are some of the most dangerous diet pills on the market and why you should avoid them.


Meridia was voluntarily removed from the market in 2010 at the urging of the FDA. Meridia, also known as sibutramine, has the potential to increase heart rate and blood pressure and carries a host of dangerous side effects. The FDA and other international regulatory bodies cited sibutramine as capable of causing:

    • Headaches
    • Nausea
    • Insomnia
    • Dizziness
    • Upset Stomach
    • Confusion
  • Depression
  • Restlessness
  • Suicidal Thoughts
Cases of sudden death were also reported.


Also known as Clen and previously marketed under the names VentipulminClenbuterol and Spiropent, Clenbuterol is illegal for human consumption in the United States. The International Olympic Committee banned Clenbuterol after discovering that athletes used it as a performance enhancer. Clenbuterol is used to treat horses in the United States with respiratory issues. Clen’s side effects include arrhythmia, chest pain, diarrhea, nausea, nervousness, hyperthyroidism, muscle tremors, dangerous blood pressure extremes in both highs and lows, and headaches.


Also known as DNP, Dinitrophenol literally cooks users from the inside out. DinitrophenolThe FDA banned the drug for human consumption in 1939. It was originally used in the manufacturing of explosive compounds and used as a chemical pesticide, but people sought the drug for its weight loss capabilities. DNP speeds up the body’s metabolism and raises the body’s temperature, causing intense sweating, lesions, respiratory difficulty, bleeding lips, and the formation of cataracts. DNP use claimed more than 60 lives.


This compound was originally used in ancient China to treat respiratory problems such as asthma and also functions as an appetite suppressant and stimulant. In 2005, the FDA banned ephedrine alkaloids marketed as weight loss supplements, and several professional sports organizations also banned ephedrine after it became widely known as a performance-enhancing drug. Combining ephedrine with other stimulants (such as caffeine) is sometimes fatal, and the side effects of the drug include a heightened risk of:

    • Heart Attack
    • Stroke
    • Cardiac Arrhythmia
    • Nausea
    • Tremors
    • Dizziness
  • Dry Mouth
  • Anxiety
  • Insomnia

Japan Rapid Weight Loss Diet Pill

This imported supplement was sold in three colors, offering three degrees of intensity. The FDA issued a statement in 2012 warning consumers of the dangers of these supplements, which contained phenolphthalein (a suspected carcinogen) and sibutramine—also known as Meridia.

The FDA warned against these nutritional supplements in 2006 based on the combination of stimulants and depressants present in these pills. Sold under the brand names Herbaslim and Emagrece Sim, these Brazilian diet pills are a cocktail of Librium, Prozac, and Fenproporex. The supplements cause severe mood swings and extreme personality shifts. Another side effect is hypersensitivity to touch, similar to the effects of the illicit drugs MDMA and Ecstasy.


Contrave is a combination of existing drugs that have already gained FDA approval, such as naltrexone (a drug used to treat opiate addiction) and bupropion (an antidepressant used as a smoking-cessation treatment). Although this compound or one of its several successors may eventually gain approval and hit the market, it’s important to be wary of the dangerous side effects, including potential heart valve damage and alteration in user metabolism and mood.


Qnexa (aka Qsymia) is a combination of immediate-release phentermine hydorchloride and extended-release topiramate. This drug was orginially rejected by the FDA, but finally approved in 2012. It is not recommended to take this pill right before going to sleep, as it could give you insomnia. Other potential side effects include:

    • Seizures
    • Heart Fluttering
    • Numbness and Tingling
    • Blurred Vision
  • Headaches
  • Birth Defects (if taken while pregnant)
