For general pain relief, the standard adult dose of Advil (ibuprofen) is 400 mg every four to six hours as needed, with a maximum of 1,200 mg in 24 hours when you’re self-treating. Each regular-strength Advil tablet contains 200 mg, so that’s two tablets per dose and no more than six tablets per day.
Standard Adult Dosing
The recommended single dose for mild to moderate pain is 400 mg, or two standard Advil tablets. You can repeat that dose every four to six hours, but only as needed. If the pain is manageable with one tablet (200 mg), there’s no reason to take two.
The type of pain you’re treating can shift the timing slightly. For menstrual cramps, the dosing interval is every four hours. For fever, the interval stretches to every six to eight hours. For general pain like headaches, muscle aches, or back pain, every four to six hours is the standard window. Regardless of the interval, the 1,200 mg daily ceiling applies whenever you’re taking Advil without a prescription.
OTC Limits vs. Prescription Doses
There’s a significant gap between what’s recommended for self-treatment and what a doctor might prescribe. The over-the-counter maximum is 1,200 mg per day (six tablets). Under medical supervision, ibuprofen can be prescribed at doses up to 3,200 mg per day, typically for conditions like rheumatoid arthritis or osteoarthritis, divided into three or four doses throughout the day. Prescription tablets often come in 800 mg strength.
That higher limit exists because a doctor is monitoring you for side effects and weighing the risks against the severity of your condition. It’s not a dose you should reach on your own. If over-the-counter Advil isn’t controlling your pain, that’s a signal to talk to a provider rather than take more.
How Long You Can Keep Taking It
Advil is designed for short-term use. For pain, the general recommendation is no more than 10 consecutive days without medical guidance. The longer you take it, the higher your risk of stomach irritation, kidney strain, and cardiovascular effects. If you find yourself reaching for it daily, the underlying cause of your pain likely needs its own treatment.
Reducing Stomach Problems
Ibuprofen works by blocking inflammation, but it also reduces the protective lining of your stomach. Taking it with food, milk, or a full glass of water helps buffer that effect. An empty stomach increases the chance of heartburn, nausea, and over time, stomach ulcers. This is especially important if you’re taking it multiple times a day.
Signs You’ve Taken Too Much
Ibuprofen overdose symptoms range from uncomfortable to serious. Early warning signs include stomach pain, nausea, vomiting, and heartburn. At higher levels of toxicity, symptoms can escalate to ringing in the ears, blurred vision, severe headache, confusion, and difficulty breathing. In serious cases, overdose can cause seizures, dangerously low blood pressure, kidney failure (marked by very little urine output), or loss of consciousness. If you suspect an overdose, call Poison Control (1-800-222-1222) or seek emergency care immediately.
Who Should Be Careful With Advil
Ibuprofen isn’t safe for everyone at standard doses. People with a history of stomach ulcers or gastrointestinal bleeding face a higher risk of those problems recurring. If you have kidney disease, ibuprofen can worsen kidney function because it reduces blood flow to the kidneys. Heart disease and high blood pressure are also concerns, since ibuprofen can raise blood pressure and increase cardiovascular risk with regular use.
If you take blood thinners, ibuprofen can amplify their effect and increase bleeding risk. It can also interfere with low-dose aspirin taken for heart protection by blocking aspirin’s ability to prevent blood clots. People who are pregnant, particularly in the third trimester, should avoid ibuprofen entirely.
Dosing for Children
Children’s Advil uses a different formulation and dose based on the child’s weight. Ibuprofen is not approved for infants under 6 months old. For children 6 months and older, doses are given every six to eight hours as needed, which is a longer interval than for adults. Always use the measuring device that comes with the children’s product, and follow the weight-based instructions on the package rather than guessing based on age alone.
