What NAPROSYN SR is used for
NAPROSYN SR belongs to a family of medicines called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).
NAPROSYN SR relieves pain and reduces inflammation (swelling, redness and soreness) that may occur in different types of arthritis including rheumatoid arthritis, osteoarthritis and ankylosing spondylitis.
Although NAPROSYN SR can relieve the symptoms of pain and inflammation, it will not cure your condition.
As the active ingredient in NAPROSYN 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.
Your doctor may have prescribed NAPROSYN SR for another purpose.
Ask your doctor if you have any questions why NAPROSYN SR has been prescribed for you.
This medicine is available only with a doctor’s prescription.
NAPROSYN SR is not addictive.
