Summary
Pills have saved the lives of many injured survivors. Using them causes your health to be fully restored (after a short delay). So the perfect time to use them is if you don't have time to use a Medkit, or if you don't have one. Rounds, where you don't buy these from the In-Game Store, are extremely uncommon.

Background Story
Developed and produced by a small lab, they were intended to be cheap, effective and able to last long, and were also originally designed to help those in less developed countries to have access to some form of medication. It is well known due to the company's usage of non-labelled bottles. Their overall versatility made them common in pharmacies and hospitals around the world. And so, after a few scavenging missions by the military, they are now extremely common. Their effect is probably due to the fact that all survivors chug the whole thing. Without water. Sort of frightening, actually.

Tips

 * Buy some Pills from the In-Game Store if your health is getting low, so you can keep on fighting.
 * You can give another survivor pills by right-clicking on them while holding it.
 * Use this on people you defib, it's faster than them buying pills themselves.
 * Keep a safe distance from zombies when taking some Pills, as the animation takes a second to work.
 * Right after you take Pills, take some damage from a zombie or radioactive waste to stop your temporary health from decreasing.
 * You might not notice that you are taking damage as you usually do when temporary health is still on, due to neither the red flash or damage audio playing. Look at your health bar once in a while.
 * Can be very useful on Bosses due to the short delay.
