A few years ago, after a lot of people had bad reactions, they determined that a substance in grapefruit juice can sometimes dramatically increase or decrease the effect of the drug. If you swallow your pills with grapefruit juice, you may end up getting really messed up, or the drug may end up having no effect at all.

Grapefruit juice is a burden to your liver and reduces the liver's capacity to break down the drug. This can cause poisoning by either the drug itself or by some of its derivatives. For the same reason, many drugs should not be combined with alcohol.
The warning is to be taken seriously. Actually, I think it's scandalous that grapefruit juice is not labeled with the same warning since not everybody read the instructions on their medicine carefully.

There are certain acids in grapefruit, that can counter-act with certain drugs.....making the drugs ineffective.

Because it will alter the chemicals in the drugs. It will either make it too potent or too weak.
