Aspirin is not safer. Aspirin is not "good for you" apart from narrow groups of people taking very small doses of aspirin.
Aspirin can be harmful to the stomach lining; aspirin can be fatal to people under 12; aspirin has a number of risky side effects; aspirin can be very dangerous for some people with under-lying conditions.
Thats fear mongering. Aspirin one of the safest drugs known to man, has a much longer history than Tylenol, and some scientists promote a more aggressive use of it in the populace.
Unfortunately, you can't just claim that Aspirin (ASS) is safer than Tylenol (Paracetamol).
Among the NSAIDs, aspirin is the strongest anti-coagulant, and the anti-coagulation effect can last for weeks. While small doses of ASS are beneficial for people who are at risk for thrombosis, they significantly raise the risk of eg. brain haemorrage.
You could of course take something like ibuprofen, which affects coagulation less. But all NSAIDs attack your stomach, so after some time you'll have to start taking something like pantoprazol to "protect" your stomach...
AFAIK, paracetamol doesn't affect blood clotting and it doesn't attack your stomach. It's dangerous if you take doses of more than 3 gram per day, and you really shouldn't take it if your liver is failing. Alcohol can also cause severe side effects when taking paracetamol.
There is no "perfect drug". If there was a drug that would only have positive effects on our body, evolution would have made our bodies produce that substance on their own.
Mainly for three reasons
- you may not want an anti-coagulant
- you have a sensitive stomach
- Tylenol may be safer for breaking a fever due to liver interaction
