Overview of Ibuprofen

Ibuprofen belongs to a class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs). It works by reducing hormones that cause inflammation and pain in the body.

OTC versions are typically available in 200 mg doses and are widely used for minor aches and pains, headaches, and fevers.

Why 800 mg Is Prescription-Only

Ibuprofen 800 mg is not available over the counter because it delivers a higher dose and carries a greater risk of side effects.

Doctors prescribe this dosage when lower doses are ineffective for managing moderate to severe pain or chronic inflammatory conditions.
