Updating, I now don't drive on day of treatment, and 2 days following. I found steroids make me a bit hyper/manic, and I found my judgement/concentration was not the best.
I recommend you plan NOT to drive day of treatment, at least for the first cycle. You will have premeds of steroids and strong anti nausea. It is not unusual to feel sleepy/groggy.
After that perhaps have another driver with you the first time to see how you go. First time I drove on day following chemo, I didn't realize my judgment was impared until I was actually driving. I had to super concentrate, and really pay attention at roundabouts and junctions. Felt like I was a bit drunk, I got a bit of a fright, especially as I had my Dds in the car. Luckily it was non-peak light traffic.
That was cycle one, I decided to not take that chance again.
But SEs are different person to person. So you might be fine. But I highly recommend you make other arrangements for day of treatment.
Another thing to note, chemo appt takes hours. My first 4 cycles took 4.5-5 hours. Sometimes delays in starting if all nurses busy, sometimes delays in getting bloods back. Tax appts are taking me 6 hours. I start at 9am and am out around 3.
