Given the global shortage of Pegylated Interferon till July 2025, I, like others, have been asked to increase my dosage but decrease the frequency of my injections.
I was previously administering 45mcg a fortnight and was told to increase this to 90mcg every three weeks. Personally I’m happy with this as my counts are stable: it utilises the whole syringe and it’s more convenient to do fewer injections. However, the 90mcg syringe (which comes in a box labelled ‘90mcg’) seems to have quite a lot of excess liquid ABOVE the 90mcg black line. Does this mean there is actually around 135mcg in every 90mcg syringe, and that I inadvertently injected more than I needed to?
I’d appreciate an answer from someone who has definitive knowledge of this, rather than an educated guess!
