Interferon beta-1a
"My doctor like so many others I'm reading, left it up to me to decide which drug to try first. I have systemic health issues, MS is just one of them on the list. I tried the Avonex pen Monday 12/5/16, and the side effects sent me to the ER yesterday. 5 days of misery. I'm having trouble urinating, complete body muscle pain when I move, dizzy, and non stop random chills sweats. Its intolerable. Here's what you need to know that the drug companies and doctors aren't telling us. There's no drug to counteract the side effects from this drug and it will be in your system for 30days. To hear this from the ER doctor sent me over the edge. I would've NEVER tried this drug had I'd known this. Not to mention the non stop calls from Bio   wallgreens."
