I’ve had a sore throat for a week, so I actually broke down and went to a doctor. He gave me a couple things, and one of them says:
Possible Side Effects: SIDE EFFECTS that may occur while taking this medicine include diarrhea, nausea, vomiting, bad taste in mouth, indigestion, stomach pain or discomfort, or headache.

CHECK WITH YOUR DOCTOR AS SOON AS POSSIBLE if you experience emotional or mood changes, confusion, hallucinations, depression, nightmares, or trouble sleeping. If you notice other effects not listed above, contact your doctor, nurse, or pharmacist.
The captial letters are from what was written, the bold/italic is my own emphasis.
