Nicorette patches during ramadhan
A Nicorette patch contains nicotine. They are a type of medicine known as nicotine replacement therapy (NRT) and are used to help smokers give up the habit.
The way these patches works is that the nicotine in the patches is absorbed continuously from the patches, through the skin and into the bloodstream. (Source: Medlink)
This procedure is similar to a person taking injection in the state of fasting. The ruling regarding this is that the fast remains intact. (Ahsanul Fatawa p.432 v.4)
Therefore, in the aforementioned scenario, by using nicorette patches, ones fasts will not break.
