Fasting: Do Injections Invalidate the Fast in Ramadan?

English:

Question #763:

Please explain your view on having injections while fasting during the blessed month of Ramadan?

Answer #763:

It is based on obligatory caution for the fasting person to avoid having any kind of supportive, nutritional or intravenous injections. The same rule is applied to all kinds of intravenous fluid infusions. However, there is no problem in using non-nutritional intramuscular injections, like antibiotics, pain killers or anesthetic injections.
