Paracetamol

The advice for these painkillers is to take 2 every 4 hours (Max 8 per day). Would it be more effective to take 1 every 2 hours?

The effectiveness of a drug depends upon its pharmacokinetics - how quickly the tablet dissolves, how quickly it leaves the stomach, amount destroyed by the liver and level achieved in the blood. Then it has to get through the blood-brain barrier. My guess is that you would get a more effective level taking 2 four hourly.
