Did you say Aspirin? Slowly I turn. Step by step . . . Aspirin has a Niagara Falls load of side effects. Would you like me to list them so you can get into your barrel? LOL!
Seriously, even the most common medicines have side effects. All those medicine ads on TV name side effects and warn you to call for medical aid if you experience them. Medicine is an art, because humans have differences.
