Took the wrong thing.

Patient: Hello ive made a horrible mistake. I took alka seltzer and 2 extra strength Tylenol at the same time. I didn’t realize that alka seltzer had a pain killer in it asa. after further reading both packages I noticed it said not to mix these two in the caution areas. how bad of a mistake have I made and what should I do? I currently feel normal haven’t had any pain or bad interaction.

Symptoms: My original symptoms were nausea and sore throat
