In brief: Serious

Acetaminophen (apap, tylenol) overdose can kill the liver, and kill the overdoser. It is one of the most commonly overdosed over-the-counter medications, partly due to misconception that if it is over-the-counter then it cannot be all that harmful.
It is safe within listed limits. Pseudoephedrine overdose can speed up the heart to dangerous levels or raise blood pressure to dangerous levels.

In brief: DayQuil

An overdosage of the Acetaminophen can cause liver failure, too much Pseudoephedrine can cause heart arrhythmias, and too much dextromethorphan can lead to breathing problems and hallucinations.
Do not take more than the recommended dose!
