For general pain relief, adults can take 200 to 400 mg of Advil (ibuprofen) every four to six hours as needed, with a maximum of 1,200 mg in 24 hours when using the over-the-counter version. That’s essentially three to six tablets per day, depending on the dose per tablet, spaced at least four hours apart.
Standard Adult Dosing
Most over-the-counter Advil comes in 200 mg tablets. For mild to moderate pain, the typical dose is one to two tablets (200 to 400 mg) every four to six hours. For menstrual cramps specifically, 400 mg every four hours tends to work better than lower doses.
The key number to remember is 1,200 mg per day. That’s the ceiling for self-directed, over-the-counter use. Prescription-strength ibuprofen can go up to 3,200 mg per day for conditions like rheumatoid arthritis or osteoarthritis, but those higher doses are split into three or four doses throughout the day and monitored by a doctor.
How Many Days in a Row Is Safe
The frequency per day matters, but so does how many consecutive days you take it. For pain, the general recommendation is no more than 10 days in a row without medical guidance. For fever, that limit drops to three consecutive days. If your pain or fever hasn’t resolved within those windows, the underlying cause likely needs attention rather than more ibuprofen.
Take It With Food
Ibuprofen is hard on the stomach lining. Taking it on an empty stomach increases your risk of irritation, ulcers, and bleeding in the digestive tract. The simplest protection is to take your dose at the end of a full meal, or with an antacid if eating isn’t practical. This is especially important if you’re taking multiple doses per day over several days.
Dosing for Children
Children’s ibuprofen follows different rules. Kids can take it every six to eight hours (not every four hours like adults), and the dose is based on weight rather than a fixed number. Ibuprofen is not considered safe for infants under six months old. For children under four years old, avoid combination cough and cold products that contain ibuprofen, as these carry serious risks in young children.
Who Should Avoid Advil
Ibuprofen raises the risk of heart attack and stroke, and that risk climbs with higher doses and longer use. If you’ve recently had a heart attack, ibuprofen is off the table unless a doctor specifically tells you otherwise. The same applies before and after coronary artery bypass surgery.
People with kidney disease, liver disease, heart failure, or a history of stomach ulcers should be cautious. Ibuprofen can cause ulcers or bleeding anywhere in the digestive tract, sometimes without warning symptoms. If you have asthma along with nasal polyps or chronic congestion, ibuprofen can trigger breathing problems.
Pregnant women should not take ibuprofen at or after 20 weeks of pregnancy, as it can harm the fetus and complicate delivery. Adults 75 and older face higher risks from regular use and should weigh those risks carefully.
Watch for Interactions With Aspirin
If you take daily low-dose aspirin for heart protection, ibuprofen can interfere with aspirin’s ability to prevent blood clots. Both drugs are fine to use, but timing matters. The FDA recommends spacing them apart so the aspirin can do its job. If this applies to you, ask your doctor or pharmacist about the best schedule for taking both.
Blood thinners and other anti-inflammatory drugs also interact with ibuprofen, increasing the chance of bleeding. If you’re on any medication that affects clotting, check for interactions before adding Advil to your routine.
A Practical Schedule
For a typical headache, muscle ache, or minor injury, start with 200 mg (one tablet). If that’s not enough after an hour, you can take a second tablet, then wait at least four to six hours before your next dose. Most people find that two or three doses per day handles everyday pain without pushing close to the daily limit.
If you find yourself reaching for Advil daily, that’s a signal to reassess. Chronic use, even at moderate doses, accumulates risk to your stomach, kidneys, and cardiovascular system. Short courses at the lowest effective dose remain the safest approach.
