Not sure but would wonder about the lemon content pushing you out of ketosis.
I took paracetamol caplets - these are the ones that are not covered with any kind of coating.
I had a cold during my first week on CD restart and the paracetamol, plenty of rest and fluids.
No way, it's full of sugar and citric acid and other demon stuff. The only active ingredients are paracetamol (which you can just swallow) and a decongestant. You could get some Olbas Oil on a tissue to sniff, or one of those Vicks vapour sticks you stuff up your nose instead. It's so horrid being ill on this diet though It's hard to be good and virtuous when you feel rubbish!
