Brand-name Tylenol is relatively expensive, but generic acetaminophen/paracetamol is dirt cheap in the US. Here are 200 tablets of 500 mg each for $4.00, i.e. $0.02 per tablet: http://www.walmart.com/ip/Equate-Extra-Strength-Value-Pack-A...

In Switzerland, I _can't_ buy more than ~2 [1] packages with 16 pills (500mg acetaminophen/paracetamol) at a time without a prescription from my doctor. And the biggest package size is 100, but that always needs a prescription. Also, you can only buy it at a pharmacy anyway.
[1]: it depends a bit on the pharmacy/pharmacist, sometimes you can get away with 3, but they start asking questions and propose you just come back again when you used up the 2 packages they are willing to sell to you.
paracetamol is nasty stuff - dying from it is not pleasant, and it's surprisingly easy to do.
The only cases I'm aware of where purchase numbers are limited for OTC drugs is when separate laws targeting drug precursors impact them, which is why you can't buy large numbers of pseudoephedrine tablets at once (they can be used to manufacture meth).
The FDA does seem to be reducing the maximum dosage of each tablet, though: from 2014 the maximum will be 325mg, so the 500mg tablets linked above will be phased out. But that change seems aimed at reducing accidental liver damage from excessive "normal" use, rather than aimed at reducing suicides from deliberate overdoses.
There are exceptions (but I'm not sure if they're from the Law Enforcement side, or the FDA). For example, you can't buy Sudafed (whose active ingredient, pseudoephederine(?), is used to make meth) without severe restrictions: not more than a pack a day, need a valid ID, etc.

Do you (or anyone else) have some concrete data for incidence rate of fatal overdoses in the U.S.? I'm curious if it's really all that common.
