"Does taking antibiotics intravenously, diluted with a saline nutrient solution, invalidate the fast? "

"The resolution of the Islamic Fiqh Academy views that therapeutic injections, whether subcutaneous, intramuscular, or intravenous, do not break the fast, with the exception of nourishing fluids and injections. The differentiation between types of injections depends on whether they are nourishing or not, and an antibiotic mixed with a saline solution does not make the injection nourishing. Nourishing injections are those that take the place of food and drink or substitute for them, and injections that do not substitute for eating and drinking do not break the fast, whether they are in the vein, thigh, or any other place. Needles are of two types: what substitutes for food and drink breaks the fast, and what does not substitute for them does not break the fast, whether it contains strengthening for the body or not.
