Medication - How long do I have to wait to take Advil after taking Tylenol for pain relief?

I read an article yesterday, 10/21/2020, from the Society of American Anesthesiologists (asahq.org/pain management) which said "taking Ibuprofen (Motrin or Advil) with Acetaminophen (Tylenol) can be just as effective as opioid (narcotics) in controlling pain.
Depending on the type of pain you have. These medications should only be combined as directed by your doctor."
I know this doesn't exactly answer your question, however, it appears it is "safe" to combine Advil with Tylenol.
I hope this information helps you.

You should have taken the Tylenol first and then the advil but thats. Alright sometimes you just need 250 mg and that when the advil helps out but check with your doctor cause there is still a lot we don't know about Tylenol

Hi Alvacamp
As far as I know you don’t need to wait as they are two entirely different medications.
I often have alternated both in a schedule when I have pain or inflammation taking one then two hours later taking the next alternating so that I take each every 4 hours and the only thing I suggest is that if you can, have a bit of toast or crackers on your tummy if your one for an upset stomach with anti-inflammatory medications because that is somewhat of a load on an empty stomach.
No doctor here, just in the medical field for 25 years and we have suggested this same alternating schedule to some post-op patients who wish to avoid narcotic use post procedure but have some mild to moderate pain.
Hope you feel your best soon.

3-4 hours.
