Answer:

Consuming anything—whether food, drink, or medication—will break your fast. If you have a medical condition requiring you to take medication during the day, it is advised to refrain from fasting and make up for it later when your health allows. However, for those facing a terminal illness with no possibility of recovery, fasting is not required. Instead,  they are obligated to offer fidyah. For more information on fidyah, please refer to the previous response.
