I have expired alli and want to know if anyone thinks it will still be effective?

9 Jan 2010

It should be fine. There was a study done by the FDA with a stock pile of OTC drugs and prescription drugs that the army had that were expired. They used 15 year old drugs. They determined that 90% of them were still as effective as when they were first manufactured. There may be some loss of potency (5% to 25% according to this study.) I personally believe they will be as effective as when you first purchased this product. Hope this helps! Good luck!
