 Belviq Vs Xenical: Safety

Xenical has been in use for more than 10 years now. Millions of people have already tried this diet pill all over the world. In many countries, Xenical in now considered an Over the Counter drug or OTC, and you would not need a prescription from your doctor to buy Xenical. This is a testament that Orlistat is generally safe to use by overweight people and is very well tolerated in terms of side effects.

These studies will take note of various side effects and the over all tolerability of Lorcaserin. The FDA will also take a special notice to events leading to cardiovascular problems like heart attack and stroke.
