Personal Findings after trialling FIaSP for several weeks. Need as much as 60% more FIaSP for same amount food intake:- FIaSP daily Split 5/7/8 units - (The longer I was on FIaSP the more I needed) Personal NovoRapid daily split 3/5/6ish units FIaSP Very slow to recover from 10+ corrections - plus need more! Seemed odd how an insulin that works quicker takes so long to correct ♂️ With FIaSP sometimes experienced Delayed post meal highs after approx 3hrs - appears to tail off quicker than Novorpid. FIaSP Very good in morning to counter Liver dumps Previous Novorapid Libre average recording 80% (High and low split generally 10% each) Achieved similar with FIaSP (Below) but found harder to maintain. FIaSP more susceptible to warmer temperature & doesn’t last as long out fridge. Used Frio cooler which I don’t do with NovoRapid unless abroad on holiday FIaSP Disposable Pen mechanism doesn’t feel as ‘certain’ as Novorapid pen - small shots sometimes left me wondering if it actually administered. FIaSP pen same & similar colour to Tresiba pen so could easily be confused. Conclusion Evidently FIaSP advantage is it works quicker so able to decrease injection lead time. Also worked better to counteract liver dumps. I will be reverting back to Novorapid as more consistent & reliable to ensure better overall balance. I also don’t need to administer as much.
