Most adults should take 1 to 2 Advil tablets at a time, with each tablet containing 200 mg of ibuprofen. That means a single dose is 200 to 400 mg. You can repeat that dose every 4 to 6 hours as needed, but don’t exceed 3 doses (6 tablets total, or 1,200 mg) in 24 hours unless directed otherwise by a doctor.
Standard Adult Dose
For general pain like headaches, muscle aches, or back pain, 400 mg (2 tablets) every 4 to 6 hours works for most adults and teenagers. You don’t always need to start at 2 tablets. If your pain is mild, one tablet (200 mg) may be enough, and you can always take a second if the first doesn’t do the job.
For menstrual cramps, the recommended dose is also 400 mg, but the interval is slightly shorter: every 4 hours as needed. Cramp pain tends to respond better when you stay ahead of it, so taking a dose at the first sign of discomfort rather than waiting until pain peaks can make a noticeable difference.
Maximum Daily Limit
Over the counter, the ceiling is 1,200 mg per day, which is 6 standard Advil tablets spread across the day. Doctors sometimes prescribe higher doses for conditions like arthritis, but you shouldn’t go above 1,200 mg on your own. Staying within that limit keeps the risk of stomach, kidney, and heart side effects low for short-term use.
Even at the recommended dose, try to use ibuprofen for the shortest time possible. A few days for a headache or pulled muscle is fine. If you find yourself reaching for Advil daily for more than 10 days, that’s a sign the underlying problem needs a different approach.
Timing Between Doses
Always wait at least 4 hours between doses. Taking another dose too soon is one of the easiest ways to accidentally exceed the daily limit. If you’re taking 2 tablets (400 mg) every 4 hours, you’ll hit your 1,200 mg ceiling in just three doses, which covers roughly 8 to 12 hours of the day. Spacing doses every 6 hours instead gives you more flexibility to redose later if pain returns.
A practical approach: take 400 mg, wait a full 6 hours, and reassess. If the pain has faded, skip the next dose entirely. There’s no benefit to taking ibuprofen on a fixed schedule unless you’re managing ongoing pain like menstrual cramps, where consistent dosing prevents the pain from rebuilding.
Take It With Food
Ibuprofen is easier on your stomach when you take it with or after food. It doesn’t need to be a full meal. A glass of milk, a few crackers, or a banana is enough to buffer the lining of your stomach. Swallow the tablets whole with a full glass of water.
On an empty stomach, ibuprofen absorbs faster, which can mean quicker pain relief, but it also increases the chance of nausea, heartburn, or stomach irritation. If you’re only taking a single dose for a one-time headache, an empty stomach is usually fine. If you’re dosing repeatedly over several days, eating something first matters more.
Children’s Dosing Is Different
Children’s doses are based on weight, not age, and the amounts are much smaller than adult doses. Ibuprofen should not be given to babies younger than 6 months. For older children, liquid formulations with a dosing syringe are the safest way to measure accurately. Always use the child’s current weight to determine the right amount, and dose every 6 to 8 hours rather than the 4 to 6 hour window used for adults.
Signs You’ve Taken Too Much
An ibuprofen overdose can range from uncomfortable to dangerous depending on the amount. Mild overdose often shows up as stomach pain, nausea, vomiting, or heartburn. More serious toxicity causes ringing in the ears, blurred vision, severe headache, confusion, or difficulty breathing. In extreme cases, it can lead to seizures, very low blood pressure, or kidney damage with little to no urine output.
If you or someone else has taken significantly more than the recommended dose, call Poison Control at 1-800-222-1222 or 911. Bring the bottle with you if you go to the emergency room so medical staff can see exactly what was taken.
Who Should Be Cautious
Ibuprofen isn’t safe for everyone at standard doses. People with a history of stomach ulcers, kidney problems, or heart disease face higher risks even at normal amounts. If you take blood thinners, blood pressure medication, or other anti-inflammatory drugs, ibuprofen can interact with them in ways that increase bleeding or reduce kidney function. Pregnancy, particularly in the third trimester, is another situation where ibuprofen is generally avoided. If any of these apply to you, acetaminophen (Tylenol) is often a safer alternative for simple pain relief, though it works differently and has its own limits.
