How Ibuprofen Works

Ibuprofen works by blocking enzymes called cyclooxygenase (COX-1 and COX-2), which are involved in producing prostaglandins—chemicals that contribute to pain, inflammation, and fever.

By reducing prostaglandin production, ibuprofen helps:

• Relieve pain.
• Reduce swelling and inflammation.
• Lower fever.
• Improve mobility in inflammatory conditions.
