Side Effect #3: Vomiting
When the stomach overpowers the pressures to keep food and secretions within the stomach normally, then a forced and involuntary expulsion occurs via mouth usually and that is called vomiting. There are various causes of vomiting and a few ones are food poisoning, other infections, and sometimes other problems related to the brain and central nervous system.
But it may be observed as a side effect sometimes in the people who undergo a CT scan.
