What it is used for
- Pain and inflammation from arthritis and other joint conditions
- Muscle and back pain, sprains and strains
- Period pain
- Pain from gout attacks
- Headache and dental pain
How it works
Naproxen blocks the COX enzymes that produce prostaglandins, reducing pain, inflammation and fever. It is longer-acting than some other NSAIDs, so doses are needed less often.
How it is taken
Available as standard and gastro-resistant tablets, and oral suspension. Take it exactly as your doctor, pharmacist or the label directs, usually with or after food to protect the stomach. Swallow gastro-resistant tablets whole.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.
