I've been using Dermatica for rosacea (Metronidazole, Ivermectin, Niacinamide) for 2 weeks and have just realised the headaches I've been having for the last 10 days or so might be related.
Before the Dermatica, I was using Rosex (Metronidazole) on its own for a month with no problems, so I assume it's unrelated to that part of the mixture.
Has anyone experienced similar?
