This can be a dangerous thing, to give this drug away, especially if someone is BRAF negative takes the Zelboraf, it will advance the disease rather than make it regress. It is best to contact the manufacturer Genentech/Roche and the pharmacy you bought it at and return it through them. If unopened, they may be able to properly recycle. I have to take down the personal email address listed, but you can contact each other through the forum by clicking on the name of the person.
