vision changes, slurred speech.

from various conditions. It is used to treat headaches, muscle aches,
backaches, tendonitis, dental pain, and menstrual cramps. It also reduces
pain, swelling, and joint stiffness caused by arthritis, bursitis, and gout
attacks. Reducing these symptoms helps you do more of your normal daily
activities. This medication is known as a nonsteroidal anti-inflammatory
