I have been called a weirdo many times for always reading the information that comes with medications. I still do, even for stuff i have taken many times like Tylenol.

Of course doctors and pharmacists should inform their patients and have an eye on these things. But the full legally required known documentation is always with the medication. And humans are prone to error, especially in a field as complex as medicine/pharma.

Read the things before starting the medication. Always.
