Osteomol 665 Paracetamol

I have been taking this product for many years - paracetemol 665, for my widespread osteoarthritis. It doesnt seem to do much for moderate to severe pain, but I feel more pain when I don't take it for a while. I stick to the required dosage maximum: no more than 6 tabs per day. It forms the base line of my pain management, with supplemented meds. My main concern is the bubble pack the tabs are in. I have cut myself twice on a finger in recent days on the aluminium foil that hold the tab in - today it bled quite a lot. I would like to see the manufacturers develop a safer package as it is especially sharp for us senior citizens with thinner skin. (I dont have a receipt, as I opt not to have one at the pharmacy chckout.)
