The FDA just issued one of the largest and most serious consumer alerts about over-the-counter supplements being sold for weight loss. Twenty five products were found to be tainted with active pharmaceutical ingredients that may put people’s health at significant risk.
The health risks posed by these products can be serious; for example, sibutramine, which was found in many of the products, can cause high blood pressure, seizures, tachycardia, palpitations, heart attack or stroke. This drug can also interact with other medications that patients may be taking and increase their risk of adverse drug events. The safety of sibutramine has also not been established in pregnant and lactating women, or in children younger than 16 years of age.
Rimonabant, another ingredient found in these products, was evaluated, but not approved by the FDA for marketing in the United States. The drug, which is approved in Europe, has been associated with increased risk of depression and suicidal thoughts and has been linked to five deaths and 720 adverse reactions in Europe over the last two years.

I’m going to have to agree with comment that there’s no such thing as a safe and effective diet pill.
