Sandys,

Thanks for your question. 

Grapefruit juice blocks the enzyme that the body uses to metabolize Lipitor.  If a patient who is taking Lipitor drinks grapefruit juice, the level of lipitor in the blood can increase.  If too high, this could lead to muscle problems and possibly kidney failure.  One study demonstrated that drinking grapefruit juice four times a day increased the lipitor as much as 83 per cent! 

Squirt soda has grapefruit juice - about 1 per cent, which means you would have to consume 100 ounces of Squirt to get 1 ounce of grapefruit juice, which is not a great quantity, but none the less, may have some contribution to lipitor metabolism.

This is something you need to discuss with your doctor.  If Squirt is a mainstay of your daily intake, other statin medication could be considered.  Your doctor will help you decide what is best for you.

I hope this information has been helpful.
