Is oxyelite pro tablets for weight loss safe to use? what are its side effects?

Who knows: Since it's a proprietary blend of various herbs and supplements -- no one knows what's in it. One thing we do know, however, is that it won't help you lose weight, except in your wallet. Whether it's safe or not is a different matter. That only gets studied if people develop toxicity or die after using it. Save your money and your health. Eat less/exercise more to lose weight.
