How Often Can You Take Ibuprofen?

Ibuprofen goes by brand names like Advil® and Motrin®. And if you were to open your medicine cabinet right now, chances are, you have a bottle in there, just waiting to offer up relief from fevers, headaches, cramps and other ailments.

But just because it’s readily available doesn’t mean this medication is risk-free. In fact, some estimates suggest that long-term use of NSAIDs (nonsteroidal anti-inflammatory drugs), including ibuprofen, is linked to more than 100,000 hospitalizations each year.

“People don’t always think of over-the-counter [OTC] medications as ‘real’ medicine,” says family medicine physician Matthew Goldman, MD. “But like other OTC medications, ibuprofen has real effects on your body — and it can have real risks if you don’t use it correctly.”

So, how often can you take ibuprofen safely? Dr. Goldman doses out the details.

How much ibuprofen is safe?

Unless otherwise directed, teens and adults should take no more than:

• 200 to 400 milligrams (mg) every four to six hours, as needed. That’s one or two regular-strength tablets or one extra-strength tablet.
• 1,200 mg in 24 hours.

You also shouldn’t take it longer than 10 days in a row for pain (or three days in a row for fever).

Babies younger than 6 months shouldn’t take ibuprofen. Follow dosage instructions on the packaging for older babies and kids under 12.

Prescription-strength ibuprofen allows for higher doses — up to 3,200 mg per day. In some cases, providers may recommend that for things like surgery recovery, arthrosis, severe menstrual cramps and other conditions. But taking ibuprofen at high levels should only happen under medical supervision.

“Higher doses significantly increase the risk of serious side effects, like stomach bleeding, heart problems and kidney damage,” Dr. Goldman emphasizes. “Those are risks that are best managed by working closely with a healthcare provider.”

How long does ibuprofen take to work?

Ibuprofen works fairly quickly. “You’ll usually start to feel relief within about 20 to 30 minutes,” Dr. Goldman says. “For some people, it can be even faster.”

Peak effects typically happen within one to two hours for acute pain. If you’re taking it for inflammation (like arthritis), it may take several days to a week of consistent use to feel the full benefit.

Is ibuprofen addictive?

Ibuprofen isn’t a controlled substance, and it’s not addictive in the way that things like opioids, benzodiazepines and non-medication drugs (like cocaine or heroin) are.

But regular use can lead to dependency. That means that if you’re in the habit of taking ibuprofen daily to manage ongoing pain, your body can get used to it.

“People with chronic pain can develop psychological or behavioral dependence,” Dr. Goldman says. “They can start using it to mask symptoms without addressing the root cause.”

Over time, that can mean you may need to take higher and higher doses to get the same relief. And if you stop taking it, you may experience rebound pain. That’s a problem because excessive and long-term use of ibuprofen can increase your risk for serious side effects.

“If you find yourself reaching for ibuprofen every day, that’s a sign to step back and look at what’s really going on,” he advises.

Short-term side effects of ibuprofen

Like all medications, ibuprofen comes with potential side effects — even at recommended doses. Short-term side effects may include:

• Upset stomach
• Heartburn
• Nausea
• Gas or diarrhea
• Dizziness or headache

Taking ibuprofen with food or milk can help lower the risk of stomach irritation.

Long-term complications of ibuprofen

Studies show that taking NSAIDs long term is linked to significant risks, especially if you take meds like ibuprofen every day for a year or more.

“Your kidneys are especially vulnerable,” Dr. Goldman explains. “That risk goes up if you’re dehydrated or already have kidney disease.”

Excessive use of ibuprofen can increase your risk of:

• Heart attack
• Heart failure
• High blood pressure
• Low sodium levels
• Stroke
• Stomach bleeding
• Ulcers
• Liver toxicity (rare, but possible)

What’s more, self-medicating with ibuprofen can mask underlying conditions that deserve a closer look.

“Ibuprofen is a fine strategy for relieving short-lived pains,” Dr. Goldman reiterates. “But if you find that you need it as part of your daily routine, there’s likely something larger happening that would benefit from a doctor’s attention and proper treatment.”

Medication interactions

Ibuprofen doesn’t always play nice with other medications. And some interactions can be serious. If you take any medications regularly, it’s smart to check with a healthcare provider before using ibuprofen.

Your provider may suggest avoiding ibuprofen if you also take:

• Aspirin
• Blood thinners
• Steroids
• Blood pressure medications
• SSRIs (a class of antidepressant medications)
• Lithium (often used as a mood stabilizing medication for bipolar disorder)
• Methotrexate (commonly used for rheumatoid arthritis, psoriasis and some cancers)
• Cyclosporine (an immunosuppressant medication)
• Other NSAIDs

Also worth noting: Mixing alcohol and ibuprofen can increase your risk of stomach bleeding. Don’t drink while taking ibuprofen.

When to talk to a doctor about alternatives

Sometimes, the bigger issue isn’t just how much ibuprofen you’re taking — it’s why you need it so often.

“The best treatment will not just minimize the symptoms, but also address the cause safely,” Dr. Goldman states.

He recommends checking in with a provider if:

• You need ibuprofen for more than 10 days
• Your pain or fever keeps coming back
• You’re taking it daily or almost daily
• It’s no longer providing enough relief
• You develop any worrying symptoms of excessive ibuprofen use, like black or tarry poop, vomiting blood, severe stomach pain, chest pain, shortness of breath, swelling, or yellowing skin or eyes (jaundice)

Depending on what’s causing your pain, a provider may advise treatments, such as:

• Other medications (like acetaminophen)
• Topical treatments, like NSAID creams and gels
• Hot or cold therapy
• Massage
• Physical therapy

Used correctly, ibuprofen can be an effective tool for short-term relief. But more isn’t better — and taking it too often can lead to serious problems.

“The line between effectively self-medicating and needing other options is usually crossed when ibuprofen becomes a daily habit or isn’t managing your symptoms anymore,” Dr. Goldman advises. “Your doctor can investigate the underlying cause and suggest alternatives.”
