I have accidentally frozen my new mounjaro KwikPen. I've searched and read a lot about people who had the same experience and was asking for advice if it was still safe to take it. I took the injection but I didn't feel the effect at all. I DIDN'T FEEL ILL either. So my advice is just to throw it once you exposed it to freezing temperature because it will be USELESS. There is no harm in injecting it but what's the point?
