Ocrevus at 47

Hello. I have been offered a range of drugs including Ocrevus which I was initially very excited about as I was denied it previously.

Now I have read that in older patients the risks of Breast cancer and pml and other infections might outweigh the benefits. This is because older people’s immune systems are already weaker.

Am I being too cautious. Are there and patients over 45 / 50 on Ocrevus?
