Expired medications

What are your thoughts of using expired fish medications? If so how long can you use it after the expired date?

If it has been sealed in the original packing, and kept cool and dry, then I would still use it.
If it has been opened, or stored in high temperature, then I would not use it. The medicine has probably lost its effectiveness.

It depends on what it is. Some lose effectiveness. Some become toxic.
