Not technically! If you want to get nitty gritty, the only fda approved patch cutting is with lidoderm .
That said, have seen a handful of docs recommending this to patients. When they do that, theyre basically acting on hypothetical beliefs about how the drug is distributed in the delivery system. (Ie equally) .
With flector though, the absolute worst case scenario isnt that bad, say in comparison to cutting a hormone, bp med, or systemic opioid patch.
