What CRYSANAL is used for
CRYSANAL belongs to a family of medicines called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).
CRYSANAL relieves pain and reduces inflammation (swelling, redness and soreness) that may occur
- in different types of arthritis including rheumatoid arthritis, osteoarthritis and ankylosing spondylitis
- in muscle and bone injuries such as sprains, strains, lower back pain (lumbago), rheumatism and tendonitis, such as tennis elbow
- from swelling and pain after setting broken or dislocated bones
- in menstrual cramps (period pain)
- due to migraine headache
- following surgery
- due to dental pain
Although CRYSANAL can relieve the symptoms of pain and inflammation, it will not cure your condition.
Ask your doctor if you have any questions why CRYSANAL has been prescribed for you. Your doctor may have prescribed CRYSANAL for another purpose.
This medicine is available only with a doctor's prescription.
CRYSANAL is not addictive.

How to take CRYSANAL
Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
How much to take
Take CRYSANAL exactly as your doctor has prescribed. Your doctor will tell you how many CRYSANAL tablets to take each day.
The dose your doctor recommends depends on both the type and severity of pain and/or inflammation you have.
Sprains, strains and period pain
The recommended dose is 550 mg (one tablet) given initially, then 275 mg (half a tablet) every 6 to 8 hours as needed. The total dose in one day should not be more than 1375 mg (two and a half tablets).
The recommended dose is 825 mg (one and a half tablets) taken at the first sign of a migraine. An additional dose of 275 mg (half a tablet) to 550 mg (one tablet) may be taken at least one hour after the initial dose, if required.The total dose in one day should not be more than 1375 mg (two and a half tablets).
Different types of arthritis
The recommended dose is 550 mg (one tablet) to 1100 mg (two tablets) a day (divided in two doses).
Your doctor may recommend lower doses than these, it is always best to use the lowest effective dose for your condition.
How to take it
Swallow CRYSANAL tablets whole with a glass of water or milk.
When to take it
Take the tablets during or immediately after food with a full glass of water or milk. This may help reduce the possibility of an upset stomach.
How long to take it
Do not take CRYSANAL for longer than your doctor says. Depending on your condition, you may need to use CRYSANAL, only once, for a few days, a few weeks or for longer periods.
For sprains and strains, CRYSANAL is usually only needed for a few days.
As with other NSAID medicines, if you are using CRYSANAL for arthritis, it will not cure your condition but it should help to control pain, swelling and stiffness. If you have arthritis, CRYSANAL should be taken every day for as long as your doctor prescribes.
For menstrual cramps (period pain), CRYSANAL is usually taken during each period as soon as the cramps begin and continued for a few days until the pain goes away.
Ask your doctor if you are not sure how long to take CRYSANAL for.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember and then continue taking it as you would normally.
Do not double a dose to make up for one you have missed.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
