Fear and panic attacks can be prevented by not using XTC. If it happens regularly, it is better to stop completely. XTC can intensify the mood you are in. If you don't feel comfortable and use XTC, it is very likely that the effects will be negative. So in order to prevent fear and panic attacks, you should avoid XTC use or make sure that you feel good before you use. Fear and panic attacks can work as a vicious circle. If you had a fear or panic attack after using XTC once, it is very likely to be afraid to have another attack when using again. You should realize what actually happens: you are afraid to get scared which makes you frightened, and so you will actually become frightened.
