I use this lidocaine patches for neck, back ,chest pain. They are of very good quality -effective and can last up tp 10 hours from my experience. There are 6 in each package. Size is 10cm X 14cm . You cant cut them in half. They feel good on skin but sometimes they don't hold well on body and you need to strength it with medical tape. They are a bit expensive in comparison to other brands and have no scent.
Compared to the Versatis 700mg patches only available on prescription they are ok as a 2nd choice, but the Lidocaine affect is not quite as strong, and they could be better on the stick to the skin side! A little thin and flimsy compared to the Versatis patches, which are thicker, stickier and more solid.
