Protein tablets to clean contact lenses

I use Protein Tablets to clean (remove protein) from my contact lenses. These tablets contain an ingredient called “PORK PANCREATIN”, which i think is derived from the pancreas of a pig.
I dissolve a tablet in a saline solution, and leave the contacts over night to cleanse and before putting them on again the following day i clean it again with the solution. Could you please let me know whether i can use a these protein tablets?
