Over the counter weight loss drugs
The vast majority of over the counter weight loss drugs are not subject to approval or regulation by the FDA. Therefore, there is only limited research on the hundreds of OTC diet pills out there, and nearly no long-term research. Many of these drugs, OTC or prescription may yield unwanted side effects such as diarrhea, headaches, or stomach upset. Your best course of action is to take weight loss drugs in consultation with your physician – who will of course recommend a prescription weight loss pill such as Xenical. Failing that, you need to proceed with caution.
