Hi misspammy and welcome to NT.
Thank you for the information. Many people here are on Betaseron and need to be watchful in the future for tampering. Sometimes a disgruntled employee will do something, or an injection person could have received that package and returned it. Perhaps the wrong medication. Or a first time user.
Once I waited for Copaxone and the Mail away pharmacy sent me the wrong medication. It was for someone who needed their med for life-saving purposes. I never heard of the med or remember the injectable name of it. Pharmacy was terrified she would use mine.
I called the pharmacy and the person whose name was on the package with my address, and her phone number. I asked her to please refrigerate my medication as I would hers. I told her the pharmacy was sending a person personally by car to pick up hers at my home and then come back and give me the one she had of mine. The pharmacy was hours away from both of us. I finally got mine and she got hers. It was a scary experience.
It was just an address labeling issue at wholesale end, but I could have used hers and she mine, as both were Injectables in similar boxes and amount.
That was years ago. When "C" had to be refrigerated. Maybe someone got yours by mistake and opened it, as it might have been that person's first experience with an injectable and didn't know the difference, that it was the wrong med.
I hope it was just a mistake and not tampering. People who do things like that IMO, are the worst criminals. I hope you get them to issue you a new complete package and make them seal it. I would put in a complaint with the FDA. One blister pack replacement is not correct. The whole box should be replaced, as others have said. Thanks again.
