Hello,
Taking Indocin with an expiry date of 2010 is dangerous. You may risk a couple of months post expiry, but an NSAID medication like Indocin that expired a few years back can pose serious risk to your health. It can affect your kidney and cause stomach upset. You can use an OTC pain reliever like Ibuprofen 400mg twice daily.
Hope this helps
