What is the ruling on receiving injections during the daytime in Ramadan for nourishment or medication?

It is permissible for a fasting person to receive intramuscular and intravenous injections during the day in Ramadan. However, it is forbidden to take nutritional injections because they are considered as consuming food and drink. If it is possible to take intramuscular and intravenous injections at night, that is preferable.
