Since the basic element of fasting is to abstain from eating, drinking and sexual intercourse, and to deprive the soul of these, these and similar behaviors while fasting invalidate the fast.
Eating and drinking includes everything that is customary to eat and drink. Smoking, tobacco-based smoky substances such as cigarettes, hookahs, drugs and all substances taken for addiction are within the scope of fasting prohibitions. For whatever reason, oral medications are also subject to the same provision. Do ear, eye and nose drops break the fast?
Do ear, eye and nose drops break the fast?
There is a canal between the ear and the throat. However, because the eardrum blocks this canal, the medicine does not reach the throat. Therefore, the medicine dripped into the ear does not break the fast.
One drop of the drug instilled into the nose for treatment is approximately 0.06 cm3. Some of it is absorbed by the walls of the nose, very little of it reaches the stomach. This was not seen at a level that would invalidate the fast, as was the case with the moisture remaining in the mouth after rinsing the mouth with water. Therefore, nasal drops do not break the fast.
According to the information received from the experts on the subject, the drug dripped into the eye is high in amount and some of it is thrown out with the blink of the eye. Eye drops do not break the fast either.
