I recently had cause to use a cut buprenorphine patch which had been left in its partially sealed packet for perhaps 6-8 weeks. Within 24 hours of application and the loss of effectivity of the patch it was replacing the "cut" patch seemed to result in mini withdrawal symptoms and some RLS break through. The portion of the patch also caused some irritation of the skin.
I had previously read that patches could be cut and the unused portion returned to packet without loss of effectiveness? My question is whether the partially sealed patch portion lost some of its effectiveness as not fully sealed with say sellotape etc
Has anyone any experience on this issue please?
