Consumer Medicine Information (CMI)
This leaflet provides important information about using Mersynofen. 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 Mersynofen.
Where to find information in this leaflet:
1. Why am I using Mersynofen?
Mersynofen
contains the active ingredients ibuprofen and paracetamol.
Ibuprofen belongs to a group of medicines called non-steroidal anti-inflammatory drugs
(NSAIDs).
Paracetamol works to stop the pain messages from getting through to the brain.
Your doctor may have prescribed this medicine for another use.
Mersynofen is an analgesic (pain reliever). It works to relieve acute (short term)
pain and/or inflammation associated with headache, migraine headache, tension headache,
sinus pain, toothache, dental procedures, backache, muscular aches and pains, period
pain, sore throat, tennis elbow, rheumatic pain and arthritis, and the aches and pains
associated with colds and flu.
This medicine is not addictive.
2. What should I know before I use Mersynofen?

relief, or any of the ingredients listed at the end of this leaflet

of the face or throat, red or itchy skin, skin rash, or a runny or stuffy nose when
using aspirin, or other non-steroidal anti-inflammatory drugs or analgesic products.

have a severe and extensive skin rash known as DRESS with following reactions such
as fever,rash, enlargement of lymph nodes and/or facial swelling, kidney problems,
blood disorder, inflammation of the heart, muscle weakness/pain

or heart, gastrointestinal or autoimmune problems (where your own immune system mistakenly

suffer from hayfever, nasal polyps or have chronic respiratory disorders. These may
increase the risk of an allergic reaction occurring

Tell your doctor or pharmacist if you have an infection.
Mersynofen may hide signs of infections such as fever and pain.
It is therefore possible that Mersynofen may delay appropriate treatment of infection,
which may lead to an increased risk of complications.
This has been observed in patients with serious lung infections (also called pneumonia)
caused by bacteria and bacterial skin infections related to chickenpox. If you take
this medicine while you have an infection and your symptoms of the infection persist
or worsen, consult a doctor without delay.
Serious skin reactions including Stevens-Johnson Syndrome (SJS), Toxic Epidermal Necrolysis
(TEN), Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), have been reported
in association with ibuprofen treatment. Stop using ibuprofen and seek medical attention
immediately if you notice any of the symptoms related to these serious skin reactions
described in Section

you understand these risks and how to monitor for them. See additional information

If your symptoms persist, worsen or new symptoms develop, talk to your pharmacist
or doctor.
Prolonged use of any type of pain relievers for headaches can make it worse. If this
is experienced or suspected, medical advice should be obtained or discontinued.
The habit of taking medicines for pain relief particularly in combination with other
pain-relievers may lead to permanent kidney problems including kidney failure therefore
it should be avoided.
If you take too much Mersynofen

attention.
You should immediately:

at risk of serious harms to the stomach/gut and kidneys, as well as very low levels
of potassium in your blood.
Mersynofen when taken at higher than recommended doses (for a short or prolonged period
of time), can cause damage to your kidneys and affect them removing acids properly

levels of potassium in your blood. Signs and symptoms include muscle weakness and
