If you use Ibuprofen or similar meds regularly (over months and years) you get overuse headache if you take it on more then 10 day per month. For triptane only 6 days per month. And it will loose its ability to alleviate the migraines.
The daily dosage is not relevant for this overuse problem (strangely...)
But this is only relevant for longtime use and mostly for migraine/ tension headache etc. I think the approach for rheumatic pain may be different.
