Warnings and precautions

Talk to your doctor or pharmacist before taking Abfen.

Heart attack and stroke

Anti-inflammatory/pain-killer medicines like ibuprofen may be associated with a small increased risk of heart attack or stroke, particularly when used at high doses. Do not exceed the recommended dose or duration of treatment.

You should discuss your treatment with your doctor or pharmacist before taking Abfen if you:

  • – have heart problems including heart failure, angina (chest pain), or if you have had a heart attack, bypass surgery, peripheral artery disease (poor circulation in the legs of feet due to narrow or blocked arteries), or any kind of stroke (including ‘mini-stroke’ or transient ischaemic attack “TIA”).

  • – have high blood pressure, diabetes, high cholesterol, have a family history of heart disease or stroke, or if you are a smoker.

Gastrointestinal bleeding, ulceration or perforation

Patients who have previously had gastrointestinal tract problems, especially elderly patients, should contact a doctor in the event of abdominal symptoms (especially gastrointestinal bleeding), particularly at the start of treatment.

Treatment must be stopped and a doctor consulted when gastrointestinal bleeding or ulceration occurs during treatment with Abfen.

General information on prolonged use of painkillers

In general the habitual use of (several sorts of) analgesics can lead to lasting severe kidney problems. This risk may be increased under physical strain associated with loss of salt and dehydration. Therefore it should be avoided.

Prolonged use of any type of painkiller for headaches can make them worse. If you think this applies to you stop taking this medication or any other painkillers and talk to your doctor or pharmacist.

Renal effects

There is a risk of renal impairment in dehydrated patients (especially in children, adolescents and the elderly).

Skin reactions

Serious skin reactions have been reported in association with <Brufen> treatment. You should stop taking <Brufen> and seek medical attention immediately, if you develop any skin rash, lesions of the mucous membranes, blisters or other signs of allergy since this can be the first signs of a very serious skin reaction. See section 4.


Abfen may hide signs of infections such as fever and pain. It is therefore possible that Abfen may delay appropriate treatment of infection, which may lead to an increased risk of complications. This has been observed in 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.

Tell your doctor if you :

  • – have or have had asthma (difficulty breathing), chronic rhinitis (chronic stuffy and runny nose) or allergic reactions (hives)

  • – have kidney, heart or liver problems

  • – have ever had stomach or gut problems (such as ulcerative colitis or Crohn’s disease)

  • – have Systemic lupus erythematosus (SLE, an illness that affects connective tissue, including your joints and skin) or other autoimmune diseases because of increased risk of aseptic meningitis (stiff neck, headache, nausea, vomiting, fever or disorientation)

  • – are in the first 6 months of pregnancy

  • – are planning to become pregnant

  • – are elderly (65 years and above) – this is because you may be more likely to get serious side effects, especially bleeding and perforation in the digestive tract, which may be fatal

  • – have an infection – please see heading “Infections” above.

Talk to your doctor or pharmacist before taking Abfen if any of the above applies to you.

Children and adolescents

Abfen is not suitable for children and adolescents under 18 years of age.

Other medicines and Abfen

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This is because Abfen may affect or be affected by some other medicines. For example:

  • medicines that are anti-coagulants (i.e. thin blood/prevent clotting e.g. aspirin/acetyl­salicylic acid, warfarin, ticlopidine)
  • medicines that reduce high blood pressure (ACE-inhibitors such as captopril, beta-blockers such as atenolol medicines, angiotensin-II receptor antagonists such as losartan)

In particular you should tell your doctor or pharmacist if you are taking any of the following medicines in addition to those above.

  • – diuretics (water tablets)

  • – cardiac glycosides such as digoxin (used to treat heart conditions)

  • – lithium (used to treat certain forms of depression)

  • – phenytoin (used in the treatment of epilepsy)

  • – zidovudine (an anti-viral drug)

  • – probenecid (used in the treatment of gout)

  • – steroids (used in the treatment of inflammatory conditions)

  • – methotrexate (used to treat certain cancers)

  • – medicines known as immunosupressants such as ciclosporin and tacrolimus (used to dampen down your immune response)

  • – medicines known as selective serotonin reuptake inhibitors (SSRIs) (used for the treatment of depression)

  • – antibiotics called quinolones such as ciprofloxacin

  • – aminoglycosides (a type of antibiotic)

  • – mifepristone (used for medical termination of pregnancy)

  • – any other ibuprofen preparations, such as those you can buy without a prescription

  • – any other anti-inflammatory pain killer including acetylsalicylic acid (e.g. Aspirin)

  • – cholestyramine (a drug used to lower cholesterol)

  • – medicines known as sulphonylureas such as glibenclamide (used to treat diabetes)

  • – voriconazole or fluconazole (types of anti-fungal drugs)

  • – ginkgo biloba herbal medicine (there is a chance you may bleed more easily if you are taking this with ibuprofen).

Some other medicines may also affect or be affected by the treatment of Abfen. You should therefore always seek the advice of your doctor or pharmacist before you use Abfen with other medicines.

Abfen with alcohol

If you drink alcohol while taking this medicine you may be more likely to get side effects.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

  • Do not take this medicine if you are in the last 3 months of pregnancy.
  • Talk to your doctor or pharmacist before taking this medicine if you are in the first 6 months of

pregnancy or you are breast-feeding. You should only take this medicine on the advice of your doctor.

  • Tell your doctor or pharmacist before taking this medicine if you are planning to become

pregnant or if you are having problems getting pregnant. This is because this medicine may make it more difficult to get pregnant when used over a long period of time. However, it is unlikely that using this medicine occasionally will affect your chances of getting pregnant. This effect usually goes away when you stop taking the medicine.

Driving and using machines

This medicine may make you feel dizzy or sleepy. If this happens, do not drive or use any tools or machines. Also, do not do anything else where you need to be alert. This particularly applies in combination with alcohol.

Abfen contains sucrose

Sucrose is a sugar. If you have been told by your doctor that you cannot tolerate or digest some sugars, talk to your doctor before taking this medicine. Each sachet contains 3.3 g sucrose. This should be taken into account in patients with diabetes mellitus.

Abfen contains sodium

This medicine contains 197 mg sodium (main component of cooking/table salt) in each sachet. This is equivalent to 9.9% of the recommended maximum daily dietary intake of sodium for an adult.

Talk to your doctor or pharmacist if you need 2 or more sachets daily for a prolonged period, especially if you have been advised to follow a low salt (sodium) diet.

3. how to take abfen

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

The product is intended for short-term use only. The lowest effective dose should be used for the shortest duration necessary to relieve symptoms. If you have an infection, consult a doctor without delay if symptoms (such as fever and pain) persist or worsen (see section 2 ).

How much to take

  • Empty the granules from one sachet into a small glass of water (about 125 ml).
  • Make sure that you use all of the granules in the sachet.
  • Stir the medicine until it stops bubbling and the granules have dissolved – this will make an

orange flavoured, fizzy drink.

  • If you use more than one sachet at one time, you should use more water. Use about 125 ml for

each sachet of medicine.

If you take more Abfen than you should
