How long is it effective for past the expiration date?
Is there any danger in taking it if the bottle expiration date is a few years ?
Ty 500 (Tylenol or acetaminophen) is a pain reliever and a fever reducer.
The expiration date is the final day that the manufacturer guarantees the full potency and safety of a medication. There are only a limited number of studies investigating the effectiveness and safety of expired medicines. The general rule of thumb would be to replace it with a fresh supply if you can. But if you can't and you need the medicine then take it - there are no reports linking expired medication use to human toxicity.
