Does Xenical orlistat decrease contraceptive pill effect?

Can the xenical orlistat remedy absorb the contraceptive pill as it does with the ingested fats? Does it take the effect off the pill? What are the rich of using both?
Expert answer:

Xenical or Orlistat does not absorb anything, much less fat, it is a lipase inhibitor (the fat digestion enzyme in the intestine) because the fats are not digested, they can not be absorbed and are eliminated in the feces. Xenical or Orlistat does not decrease the effect of contraceptive. Second, the description of the medicine (package insert), there seems to be no risk in using the two together.
