For most adults, the standard Advil dose is 1 tablet (200 mg), taken every 4 to 6 hours as needed. If one tablet doesn’t relieve your pain or fever, you can take 2 tablets (400 mg) per dose. The maximum is 6 tablets (1,200 mg) in 24 hours unless a doctor tells you otherwise.
Standard Adult Dosing
Each regular Advil tablet, caplet, or gel cap contains 200 mg of ibuprofen. The label directions are the same across all three forms: start with 1 pill and see if it works. If it doesn’t, step up to 2 pills for the next dose. Either way, wait at least 4 to 6 hours before taking another dose. This applies to adults and children 12 years and older.
Here’s what that looks like over a full day:
- Per dose: 1 to 2 tablets (200 to 400 mg)
- Time between doses: 4 to 6 hours minimum
- Daily max: 6 tablets (1,200 mg) in 24 hours
The label’s guiding principle is to use the smallest effective dose. If one pill handles your headache, there’s no benefit to taking two. Research supports this: a study of 225 adults with acute pain found that 400 mg, 600 mg, and 800 mg doses all produced nearly identical pain relief after 60 minutes. A separate study found similar results comparing 200 mg to 400 mg. In other words, more ibuprofen doesn’t necessarily mean more relief, so starting low makes sense.
How Long You Can Keep Taking It
Advil is meant for short-term use. For pain, you shouldn’t take it for more than 10 consecutive days without checking in with a doctor. For fever, that window is even shorter: 3 days. If your symptoms haven’t improved by then, something else may be going on that ibuprofen won’t fix.
Children Under 12
Standard Advil tablets are not labeled for children under 12. For kids in that age group, ibuprofen dosing is based on the child’s weight, not their age, and uses a liquid or chewable formulation designed for children. You can give children’s ibuprofen every 6 to 8 hours as needed, which is a longer interval than the adult schedule. The American Academy of Pediatrics recommends against giving ibuprofen to any infant younger than 6 months.
Prescription Doses Are Higher
If you’ve heard of people taking 800 mg ibuprofen tablets, those are prescription strength. Doctors sometimes prescribe higher doses for conditions like arthritis or severe inflammation, and the prescription daily maximum (3,200 mg) is significantly higher than the OTC ceiling of 1,200 mg. That higher limit requires medical supervision because the risk of side effects climbs with dose and duration. Don’t try to replicate a prescription dose by taking four OTC tablets at once.
Who Should Be Careful With Advil
Ibuprofen belongs to a class of pain relievers called NSAIDs, and these drugs are not equally safe for everyone. People with kidney disease, heart disease, or high blood pressure should avoid ibuprofen unless their doctor has specifically approved it. If you already have reduced kidney function, regular ibuprofen use can make it worse. The same caution applies if you take blood thinners, certain blood pressure medications, or other prescription drugs that may interact with ibuprofen.
Stomach problems are the other common concern. Ibuprofen can irritate the lining of your stomach and intestines, especially at higher doses or with prolonged use. Taking it with food or a glass of water can help reduce irritation. If you have a history of stomach ulcers or GI bleeding, ibuprofen is generally not a good choice for you.
Practical Tips for Timing Your Doses
The 4 to 6 hour window gives you some flexibility. If you take 2 tablets for a bad headache and it comes back 4 hours later, you can take another dose. But keep a mental count of how many tablets you’ve taken that day. At 2 pills per dose, you only get 3 doses before hitting the daily cap of 6 tablets. If you space doses out to every 6 hours, you’ll stay well within the limit even over a long day.
One common mistake is overlapping ibuprofen with other medications that already contain it. Some cold and flu products, migraine formulas, and combination pain relievers include ibuprofen as an ingredient. Check the active ingredients on anything else you’re taking to make sure you’re not accidentally doubling up.
