Will taking activated charcoal for bloating while you are on alli (orlistat lipase inhibitor) decrease or counteract the effectiveness of alli?

Activated Charcoal: Activated Charcoal is often given in cases of poisoning or overdoses. This is because it absorbs whatever might be in the stomach before the substance reaches the small intestine where it gets absorbed into the bloodstream. Taking the charcoal within an hour or two of Orlistat will likely reduce it's effectiveness. Try to space the charcoal dose 3 hours between each Orlistat dose.
