Do injections or a drip break the fast?

“In principle, the fast is only nullified when a substance entered into the body reaches the stomach or brain through the natural openings of the body such as the mouth, nose, front and back private parts. Therefore, taking an injection while fasting is permissible and will not invalidate the fast.”

“It is permissible to take a flu vaccine or injection when one is fasting, because the medicine is delivered to the body through a porous medium (i.e. the skin) and not through the usual oral passage or route. This medium is not contrary to the mediums that nullify the fast for substances to enter the body.”

“1. Yes, injections in the eye will not invalidate the fast. 2. Cupping whilst fasting does not invalidate the fast. However, Fuqaha have stated that if one knows, through past experiences, that cupping whilst fasting will cause weakness, then it will be Makrooh to undergo cupping whilst fasting.”

“Using the inhaler (pump) while fasting will nullify the fast as the inhaler contains medication. Through one orally taking medication while fasting or one taking medication through the nasal passage, one's fast will break. However, it will only be waajib (compulsory) for one to keep qadha for the broken fast.”
