Ibuprofen (Advil): Uses, Warnings, and Safety

What is ibuprofen?

Ibuprofen is a drug used as an antipyretic, analgesic, and anti-inflammatory. In the United States, common brand names include Advil, Motrin, IBU, and Motrin IB.

The source content also lists several ibuprofen-related ingredients or salt forms, including ibuprofen aluminum, ibuprofen lysine, ibuprofen potassium, and ibuprofen sodium.

How ibuprofen works

Ibuprofen works by inhibiting prostaglandin synthesis at the peripheral level. Prostaglandins are involved in pain, fever, and inflammation, so reducing their production helps explain ibuprofen’s effects.

What ibuprofen is used for

The source content describes ibuprofen use for several painful, inflammatory, and febrile conditions.

Oral use

• Rheumatoid arthritis, including juvenile rheumatoid arthritis
• Ankylosing spondylitis
• Osteoarthritis and other acute or chronic rheumatic processes
• Musculoskeletal and traumatic conditions with pain and inflammation
• Mild to moderate pain, including dental pain, post-surgical pain, headache, and migraine
• Primary dysmenorrhoea
• Fever

Intravenous use

The source content notes short-term symptomatic treatment of moderate pain and fever when intravenous administration is clinically justified and other routes are not possible.

Dosage information in the source content
