Taken it in advance will most of the time give you protection in preventing the occurance. No significant side effects.
Good at lowering tension? Yes, in that it helps you to relax and know that you are not likely to have tachcardia (fast heart beat which comes on suddenly) thus allowing you to be more relaxed.
