Consumer Medicine Information (CMI)
This leaflet provides important information about using PROXEN SR. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using PROXEN SR.
Where to find information in this leaflet:

Why am I using PROXEN SR?

PROXEN SR contains the active ingredient naproxen. PROXEN SR belongs to a group of medicines called Non-Steroidal Anti-Inflammatory Drugs (or NSAIDs).
PROXEN SR is used to relieve pain and reduces inflammation (swelling, redness and soreness) that may occur in different types of arthritis including rheumatoid arthritis, osteoarthritis and ankylosing spondylitis.
As the active ingredient in PROXEN SR, is released slowly into the bloodstream during the day, the tablets are not suitable for use in conditions where rapid pain relief is needed e.g. migraine attacks or in conditions needing only short term pain relief.
Although PROXEN SR can relieve the symptoms of pain and inflammation, it will not cure your condition.
Your doctor may have prescribed PROXEN SR for another reason.
Ask your doctor if you have any questions why PROXEN SR has been prescribed for you.

What should I know before I use PROXEN SR?

If you are not sure if you are taking any of these medicines, ask your doctor or pharmacist. If you are allergic to aspirin or NSAID medicines and use PROXEN SR, these symptoms may be severe. Symptoms of an allergic reaction to these medicines may include:
