Motrin and Advil are the same medication. Both are brand names for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) that reduces pain, fever, and inflammation. The only differences between them come down to branding, inactive ingredients like coatings and dyes, and the specific product forms each company sells.
Same Drug, Different Labels
Every Motrin and Advil product contains ibuprofen as its sole active ingredient. A standard adult tablet of either brand delivers 200 mg of ibuprofen. The drug works by blocking the production of prostaglandins, chemicals your body releases in response to injury or illness that cause pain, swelling, and fever. By reducing prostaglandin production, ibuprofen tackles all three symptoms at once.
The brand names exist because different companies manufacture them. Advil is made by Haleon (formerly part of Pfizer’s consumer health division), while Motrin is a Johnson & Johnson brand. Generic ibuprofen, which costs less than either, contains the exact same active ingredient at the same strength.
Where the Products Actually Differ
Although the active ingredient is identical, the inactive ingredients vary between brands and even between product lines within the same brand. Advil’s standard coated tablets contain ingredients like shellac, sucrose, and red iron oxide for the coating, while Advil Gel Caplets use gelatin, glycerin, and different dyes. Motrin IB tablets have their own set of binders and fillers. These inactive ingredients affect the pill’s appearance, taste, and texture but don’t change the drug’s effectiveness.
One difference that can matter is how quickly certain formulations absorb. In a pharmacokinetic study reviewed by the FDA, a standard Motrin IB tablet reached peak blood levels in about 120 minutes under fasting conditions, while Advil Liqui-Gels reached peak levels in roughly 40 minutes. That’s a meaningful gap if you’re looking for faster relief. The total amount of ibuprofen absorbed is the same either way; liqui-gel formulations simply dissolve and enter the bloodstream sooner.
Available Strengths and Forms
Both brands offer a range of products beyond the standard adult tablet:
- Adult tablets and caplets: 200 mg per dose (over the counter)
- Children’s liquid: 100 mg per 5 milliliters
- Infant drops: 50 mg per 1.25 milliliters
- Children’s chewables: 50 mg per tablet
Motrin tends to have a stronger presence in pediatric products, partly because of longstanding marketing to parents, while Advil has a wider variety of adult formulations like Liqui-Gels and Dual Action (which combines ibuprofen with acetaminophen). But the children’s versions of both brands use the same concentrations of ibuprofen, so switching between them is straightforward as long as you match the dosage.
Side Effects and Risks Apply to Both
Because the active ingredient is identical, Motrin and Advil carry the same risks. Ibuprofen can irritate the stomach lining, and long-term or high-dose use raises the risk of stomach ulcers and bleeding. It also affects kidney function by reducing blood flow to the kidneys. This is usually harmless in healthy, well-hydrated people taking occasional doses, but it becomes a real concern in certain situations.
Your risk of kidney problems rises significantly if you’re over 65, dehydrated, have existing kidney disease, or take blood pressure medications like ACE inhibitors or diuretics. The combination of a blood pressure drug, a diuretic, and an NSAID like ibuprofen, sometimes called the “triple whammy,” increases the rate of acute kidney injury. That risk is highest in the first 30 days of combined use.
All NSAIDs, ibuprofen included, also carry cardiovascular risks with prolonged use. The maximum prescription dose is 3,200 mg per day, but over-the-counter labels recommend no more than 1,200 mg daily (three doses of 400 mg) unless directed otherwise by a doctor. These limits apply equally whether the bottle says Motrin, Advil, or generic ibuprofen.
Choosing Between Them
For most people, the choice between Motrin and Advil comes down to price, availability, and personal preference for pill size or coating. If speed of relief matters to you, a liquid-filled capsule like Advil Liqui-Gels will absorb roughly three times faster than a standard tablet from either brand. If you’re buying children’s ibuprofen, both brands work identically at the same concentrations.
Generic ibuprofen is the most cost-effective option and is held to the same FDA standards for purity, potency, and absorption as the brand-name versions. You’re paying for the name on the box, not a different medicine.
