There are some medications that are implanted under the skin to provide a specific concentration of the drug in the blood for a long period, for example a month, and some medications come in the form of a patch.

The questioner : May Allah reward you. This questioner says: There are some medications that are implanted under the skin to provide a specific concentration of the drug in the blood for a long period, for example a month, and some medications come in the form of a patch that is stuck on the skin to provide a specific concentration of the drug in the blood for a day, especially for heart patients. Does this break the fast? Knowing that some of these medications contain salts and compounds found in the food that an ordinary person consumes?

The Shaykh : This does not break the fast because it is not eating or drinking, nor is it the equivalent of eating and drinking. If a fasting person uses it in Ramadan or outside of Ramadan, he does not break his fast by doing so. Yes.
