I haven't heard any equivalent warnings issued in Europe although the potentially hepatotoxic effects of paracetamol (= acetaminophen, the principal active ingredient of tylenol) overdosing are well documented.

I couldn't find anything of particular concern on a very quick search of the web other than the usual advice on correct dosage and precautions on avoiding overdosage. The following references might be of interet concerning paracetamol/acetaminophen toxicity.

I hope this reassures you a little.
