How long should you wait between doses of Advil 600 mg?
For adults using Advil (ibuprofen) 600 mg, the usual dosing schedule is every 6 to 8 hours as needed for pain or fever.
What if you’re taking it for fever vs. pain?
The timing is the same in both cases (every 6 to 8 hours). The difference is that you should take the smallest dose that works and stop once symptoms improve.
What’s the maximum you can take in 24 hours?
Common adult guidance for OTC ibuprofen is not to exceed 3,200 mg total per day (and many labels advise staying at or below 2,400 mg/day unless a clinician directs otherwise). If you tell me whether this is OTC or prescribed and your age, I can help interpret the label more precisely.
What to watch for so you don’t space doses incorrectly
Avoid taking extra ibuprofen (or other NSAIDs) too soon, and be careful if you’re also using medicines that contain ibuprofen or other NSAIDs. If you have stomach ulcers/bleeding, kidney disease, are on blood thinners, or are pregnant, the safe dosing interval can be different—check with a clinician.
When to get medical help
Get urgent help if you have severe stomach pain, black/tarry stools, vomiting blood, trouble breathing, chest pain, or signs of an allergic reaction.
If you share your age and whether this is OTC or prescribed, I can tailor the dosing interval more safely.
