​What is this medication for?

Non-steroidal anti-inflammatory drugs (NSAIDs) are a group of medications commonly used to treat pain and reduce inflammation. It can also be used to bring down the body temperature during a fever and to relieve headaches, joint or muscle pain/inflammation, gout attacks, toothaches and menstrual pain.

Examples of oral NSAIDs available over the counter include Ibuprofen and Naproxen. Other NSAIDs which require a prescription from the doctor include Diclofenac, Mefenamic Acid, Ketoprofen, Piroxicam, Indomethacin, Celecoxib and Etoricoxib.

How should I take/use this medication?

As there are different strengths and dosage forms for these medications, please make sure to take it as recommended on the label. Please check with your healthcare professional if you are unsure.

NSAIDs should be best taken with meals to reduce stomach irritation. Your healthcare professional may also give you an additional medication to protect the stomach. E.g. famotidine, omeprazole.
Do not exceed the dose recommended on the label as taking too much NSAIDs over time may cause serious stomach, kidney or heart problems.

What should I do if I forget to take/use this medication?

NSAIDs can be taken on as needed basis for short term use or regularly for certain conditions as prescribed by the doctor.  

If your doctor has prescribed NSAIDs for you to be taken regularly, do not stop taking your medication without checking with your healthcare professional.
