Can I drink pineapple juice while taking lipitor?

Hello, since February I have been eating a lot of pineapple. Chopped up in juice is what I usually buy in the produce department. Is this dangerous. My mouth is sour when I reach a certain point. But I crave this. Can it cause any bad effects, other than my mouth being sore?

Yes - that's fine.
Grapefruit is the only juice you need to avoid.
