I take this, you do have to be careful and listen to your body. But it's the first thing that's really helped me in more ways than weightloss. Every medication has its problems...I nearly died of sepsis caused by ibuprofen, I didn't take over the prescribed dose, I didn't abuse them, they should be prescription only because thousands end up with lifelong damage from them but no-one promotes that due to the amount of money pharmacies make.
Many people die to complications because of obesity. Be mindful if you take it, don't rush to up doses, listen to your body.
