Advil and Motrin are the same drug. Both are brand names for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) that reduces pain, fever, and inflammation. The active ingredient, the dose, and the way it works in your body are identical. The only differences between them come down to branding, inactive ingredients, and the specific formulations each company sells.
Why Two Names for the Same Drug
Ibuprofen was originally developed in the 1960s and has since been manufactured by multiple pharmaceutical companies. Advil is made by Haleon (formerly part of Pfizer’s consumer health division), while Motrin is a Johnson & Johnson brand. Both companies sell over-the-counter versions at the standard 200 mg strength, and prescription-strength ibuprofen (400 mg, 600 mg, and 800 mg tablets) is also available under both names or as a generic.
Choosing between them is like choosing between two brands of the same bottled water. The product inside does the same thing. Store-brand ibuprofen, which typically costs less, is also identical in its active ingredient.
How Ibuprofen Works
Ibuprofen blocks enzymes in your body that produce compounds involved in pain signaling and inflammation. These enzymes normally convert a fatty acid in your cells into substances that trigger swelling, pain, and fever. By blocking that conversion, ibuprofen reduces all three symptoms. It’s considered a nonselective NSAID, meaning it also blocks a related enzyme that helps protect your stomach lining, which is why ibuprofen can cause stomach irritation if taken frequently or on an empty stomach.
Where the Brands Actually Differ
The meaningful differences between Advil and Motrin are in their inactive ingredients: the fillers, coatings, dyes, and binders that hold the pill together and affect how it looks and tastes. For most people, these differences don’t matter at all. But if you have a sensitivity to specific dyes or preservatives, the ingredient lists are worth comparing.
Advil tablets, for example, contain sucrose, synthetic iron oxide, corn starch, and sodium lauryl sulfate among their inactive ingredients. Advil Gel Caplets add FD&C Red No. 40 and FD&C Yellow No. 6, which are artificial dyes some people prefer to avoid. Motrin tablets use a different set of inactive ingredients, including lactose and hypromellose. If you’re lactose-sensitive, that’s a reason to pick Advil. If you want to avoid certain dyes, standard Advil tablets or Motrin tablets might be the better choice over Advil Gel Caplets.
Formulations and How Fast They Work
Both brands sell ibuprofen in several forms: coated tablets, caplets, chewable tablets, liquid-filled gel capsules, and oral suspensions for children. The liquid-filled gel capsules (like Advil Liqui-Gels) contain ibuprofen in a pre-dissolved form, which is absorbed somewhat faster than a standard tablet. A systematic review published in the Journal of Pharmacy & Pharmaceutical Sciences found that liquigel capsules provided meaningfully better pain relief at 60, 90, and 120 minutes compared to solid tablets, though the difference wasn’t significant at the 30-minute mark. So if speed matters to you, the formulation you pick (gel capsule vs. tablet) matters more than the brand name on the box.
Standard tablets from both brands dissolve at roughly the same rate, since they contain the same amount of ibuprofen in similar tablet designs.
Children’s Versions
Children’s Advil and Children’s Motrin are also the same drug at the same concentrations. Both come as liquid suspensions, and both can be given every six to eight hours. The main differences are flavor options and the measuring tools included in the box.
One thing to watch: infant ibuprofen drops are more concentrated than the children’s liquid version. If you’re switching between infant drops and children’s liquid, or between brands, always use the dosing syringe or cup that came with that specific product. The volume you measure out for a correct dose will be different between concentrations, even though the brand names sound interchangeable.
Which One Should You Buy
If you have no ingredient sensitivities, the cheapest option is the right one. Generic ibuprofen, Advil, and Motrin all deliver the same drug at the same strength. Your body cannot tell the difference. If you prefer gel capsules for slightly faster relief, both brands offer them, and so do most store brands. The only practical reason to favor one over the other is a specific inactive ingredient you want to include or avoid.
