Motrin and Advil are the same medication. Both are brand names for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) sold over the counter in 200 mg tablets. The pill inside each box is chemically identical, so choosing between them comes down to price, packaging, and which product line offers the formulation you prefer.
Why Two Names for the Same Drug
Ibuprofen was first developed in the 1960s, and over the decades multiple companies licensed the right to sell it under their own brand names. Motrin (and its over-the-counter version, Motrin IB) and Advil both contain ibuprofen as their sole active ingredient. Generic store-brand ibuprofen is also the exact same drug. There is no difference in effectiveness, safety, or how quickly any of these versions work. If you’ve been alternating between brands or wondering whether one is “stronger,” it isn’t.
How Ibuprofen Works
Ibuprofen blocks enzymes in your body that produce prostaglandins, the chemical messengers responsible for pain, inflammation, and fever. It does this by competing with the raw materials those enzymes need, which is why its effects are temporary rather than permanent. Pain relief typically lasts four to six hours per dose.
The anti-inflammatory and pain-relieving benefits come primarily from blocking one specific enzyme (COX-2), while the stomach-related side effects are linked more to blocking a related enzyme (COX-1) that helps protect your stomach lining. This is why ibuprofen can upset your stomach, especially on an empty stomach or with frequent use.
Available Forms and Strengths
Both Advil and Motrin sell the standard 200 mg adult tablet, but each brand has expanded into slightly different product lines over the years. Advil, for example, offers liquid-filled gel capsules and combination products that pair ibuprofen with a sleep aid. Motrin has historically had a strong presence in the children’s medication aisle. For practical purposes, if the label says “ibuprofen 200 mg” on two different boxes, the contents are interchangeable.
Children’s versions of both brands come in several forms:
- Infant concentrated drops: 50 mg per 1.25 mL, packaged with a dropper or syringe
- Children’s liquid: 100 mg per 5 mL, packaged with a dosing cup
- Chewable tablets: 50 mg each
- Junior strength tablets: 100 mg each
These concentrations are the same regardless of brand. What matters is matching the dose to your child’s weight, not picking a particular brand name.
Dosing for Adults
The standard over-the-counter dose for adults and teenagers is 200 to 400 mg every four to six hours as needed. For menstrual cramps, 400 mg every four hours is a common recommendation. You should not exceed the maximum listed on the product label (typically 1,200 mg in 24 hours for OTC use) unless directed otherwise by a doctor. Prescription-strength ibuprofen goes higher, but that’s a different situation with closer medical oversight.
Taking ibuprofen with food or a full glass of water can reduce the chance of stomach irritation. It works faster on an empty stomach, but the tradeoff in comfort isn’t usually worth it for routine pain.
Side Effects and Risks
Because Motrin and Advil contain the same active ingredient, they carry identical risks. Most people tolerate ibuprofen well for occasional use, but there are real concerns with regular or long-term use.
NSAIDs, including ibuprofen, can increase the risk of heart attack and stroke. This applies to people with and without existing heart disease, though the risk is higher if you already have cardiovascular problems. Serious side effects can appear as early as the first few weeks of daily use, and the risk climbs the longer you take it. Ibuprofen can also interfere with aspirin’s ability to prevent heart attacks, which matters if you take a daily aspirin for heart protection.
Stomach issues are the other major concern. Ibuprofen can cause nausea, stomach pain, and in more serious cases, ulcers or gastrointestinal bleeding. People who drink alcohol regularly, take blood thinners, or have a history of stomach ulcers face higher risk on this front.
So Which Should You Buy?
Whichever is cheaper or more convenient. Generic ibuprofen from any pharmacy is the same drug at a lower price. If you prefer a gel capsule, buy the brand that offers one. If you need a children’s liquid, grab whichever is on the shelf. The active ingredient, the dose, and the risks are identical across every ibuprofen product at the same milligram strength. Brand loyalty here is purely a matter of habit.
