In brief: Recommended
Do not exceed the dose recommended on the Aspirin bottle, since Aspirin irreversibly inhibits platelets, if you exceed the dose it can cause serious bleeding, asa also can cause stomach ulcers.
If the headache is really bad you should get it checked as some headaches can be caused by life threatening conditions.

In brief: Best Headache Meds
A 2014 study indicates that medication containing a combination of acetylsalicylic acid, (aspirin), acetaminophen(paracetamol), and caffeine is more effective than acetaminophen alone.

In brief: 4g/day
The maximum dosing for most conditions is 650 mg every 4 hours for a maximum dose of 4 grams/day.
Importantly, this is for adults and should be taken with food.
