Expired Penicillin Vk Safe To Take?

My mother has some Penicillin VK left from a previous dental infection in 2005, Is it safe for her to use now?

It is too old to be effective. As pills age, the active ingredients start to break down and as time passes, you will get less and less of an effective dosage.

Taking them now, also raises the risk of developing drug-resistan bacteria.

So all around, it is not a good idea and she will be better off getting a new prescription.
