Ibuprofen is a common nonsteroidal anti-inflammatory drug (NSAID), available over the counter, used to relieve pain, reduce inflammation, and lower fever. It should be used at the lowest effective dose for the shortest time, as it can affect the stomach, kidneys, and heart.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID). It works by blocking enzymes (called COX) that the body uses to make prostaglandins — substances involved in pain, swelling, and fever. By reducing them, ibuprofen eases pain and inflammation and brings down a temperature.
What it's used for
Ibuprofen is used for mild to moderate pain — headaches, muscle and joint aches, period pain, dental pain, and pain from injuries — as well as to reduce inflammation and lower fever. It's one of the most common over-the-counter pain relievers, and higher strengths are available on prescription.
How to take it
Take ibuprofen at the lowest effective dose for the shortest time needed, with or after food or a drink of milk or water to protect the stomach. Follow the label or your prescriber's instructions and don't exceed the stated maximum, and don't take it with other NSAIDs (or with aspirin unless a doctor advises). If you need it for more than a few days for pain, or 3 days for fever, check with a pharmacist or doctor.
Common side effects
The most common side effects are stomach-related — indigestion, heartburn, and nausea. Taken at higher doses, for long periods, or by older adults, ibuprofen can cause stomach ulcers and bleeding. It can also affect the kidneys and raise blood pressure. Taking it with food and using it only as needed lowers these risks.
Warnings and interactions
Long-term or high-dose NSAID use is associated with a higher risk of heart attack and stroke, and ibuprofen can be unsafe for people with certain heart, kidney, or stomach conditions, and in the later stages of pregnancy. It interacts with blood thinners, some blood-pressure medicines, and other anti-inflammatories. Check with a pharmacist or doctor before using it regularly or alongside other medicines.
When to see a doctor
Stop and seek medical advice if you have severe stomach pain, black or bloody stools, vomiting blood, signs of an allergic reaction, or symptoms of a heart problem. See a doctor before using ibuprofen long-term, or if you have heart disease, high blood pressure, kidney disease, a history of stomach ulcers, asthma, or are pregnant.
Pregnancy & breastfeeding
General information from the FDA-approved label and NIH's LactMed database — not a personal recommendation. Always discuss your own situation with a clinician.
In pregnancy
Avoid from around 20 weeks (Generally avoided)
The FDA advises avoiding NSAIDs like ibuprofen from about 20 weeks of pregnancy, as they can affect the baby's kidneys and, later, the heart. Earlier use should still be discussed with a clinician.
While breastfeeding
Usually considered a preferred NSAID (Usually considered compatible)
LactMed reports very low levels in milk, making ibuprofen a preferred choice for pain relief while breastfeeding.
Alcohol & food:Combining ibuprofen with alcohol raises the risk of stomach irritation and bleeding.

Ways to save on Ibuprofen
Prices vary by pharmacy, insurance, and location. These are general ways to lower the cost of most prescriptions — always confirm with your pharmacist.
Ibuprofen is inexpensive over the counter, where store-brand versions match the name brand. Prescription-strength ibuprofen is simply a higher dose — ask whether taking the equivalent amount of OTC tablets is a cheaper option for you.
Ask for the genericGeneric versions contain the same active ingredient at the same strength and usually cost far less than the brand. If a generic exists, ask your prescriber or pharmacist whether it's right for you.
Compare pharmaciesThe cash price for the exact same medicine can vary a lot between pharmacies — including large chains, supermarkets, warehouse clubs, and independents. It's worth calling a couple or checking a price-comparison service.
Cash price vs. insuranceSometimes a pharmacy's discounted cash price (or a coupon) beats your insurance copay. Ask the pharmacist to check both — you're allowed to pay whichever is lower.
90-day supplies & mail orderA 90-day fill, often through mail order, can cost less per month than three 30-day fills for stable, long-term medicines. Ask whether your plan offers it.
Manufacturer copay & savings cardsMany brand-name drugs have a manufacturer copay card or savings program that can lower the price for eligible, commercially-insured patients (these usually can't be used with government insurance like Medicare).
Patient assistance programsIf cost is a barrier, patient assistance programs (from the manufacturer, or nonprofits like NeedyMeds and RxAssist) may provide medicines free or at low cost based on income. A pharmacist or social worker can help you apply.
Don't ration or split to save — ask firstSkipping doses, stopping early, or splitting tablets to stretch a prescription can be unsafe. If the cost is hard, tell your clinician or pharmacist — there are almost always better options than going without.
