| | Question about mixing ENBREL solution
I just started taking Enbrel (only 2 injections so far) after being on MTX for 4 months (worked ok [30% improvement], but my DR. and I are looking for better results). I'm hopeful that Enbrel will be the answer. So far, I have not felt a single side effect, unlike the MTX where I had occasional headaches and loss of appetite.
My question is about mixing the Enbrel solution. The instructions say that after mixing the solution, there should be no particles and the solution should be completely clear. I mix the solution, give it about 10 "twirls" (not shaking) and let it sit for about 10 minutes. The solution is completely clear and there are no particles, BUT there remains a "foamy" ring around the top of the solution even after 10 minutes. Is this normal? I want to make sure I'm getting all the medication and I didn't expect there to be this foamy ring around the top (it's almost like the foam that's left on the side of a glass after you finish drinking a carbonated drink).
Is this normal, or do I have a bad batch? Since there are no particles in my solution and it remains clear, I think my batch is ok, but I wasn't expecting to see this foamy ring.
Thanks in advance.
