Hi Brett,
thank you for this question! I think it’s an important one because the use of these drugs is quite common.
Anti-inflammatory drugs like Ibuprofen are good in treating muscle and joint pain (but they don’t cure it), but they also have lots of side effects:
– they damage the kidneys (I know several athletes with acute kidney failure after a race, when taking ibuprofen),
– they cause bleeding in your stomach (this can lead to many chronic problems, including low iron)
– they can hinder the training adaptation
– they can make an injury worse if you train through it when the pain is reduced
and many more.
Acetaminophen acts a bit differently, with the main side effect of liver damage.
So the recommendation is to only take it when you need it. Take it to relieve the pain of an injury (but then stop training and don’t push through it with the drugs). I would not recommend taking it post workout, because you could hinder the adaptation. And you probably want to know how your body reacts to the training, so you can tell what was too much!? Don’t take it before competitions, because that can bring some serious risks. If you take this medication before a big goal or objective you should be aware of the risks and decide if it’s actually needed and/or appropriate.
I hope that helps!?
enjoy the pain after a good training session in the mountains!;-)
