• If they are allergic to sulfamethoxazole, trimethoprim or co-trimoxazole or any of the other ingredients of this medicine (listed in section 6).
• If they are allergic to sulphonamide medicines. Examples include sulphonylureas (such as gliclazide and glibenclamide) or thiazide diuretics (such as bendroflumethiazide – a water tablet).
• If they have severe liver or severe kidney problems.
• If they have ever had a problem with their blood causing bruises or bleeding (thrombocytopenia).
• If you have been told that your child has a rare blood problem called porphyria, which can affect their skin or nervous system.

Co-Trimoxazole should not be given to infants during the first 6 weeks of life.

If you are not sure if any of the above apply to your child, talk to their doctor or pharmacist before they take Co-Trimoxazole.

Talk to your child’s doctor or pharmacist before taking Co-Trimoxazole:

• If they have severe allergies or asthma.
• Potentially life-threatening skin rashes (Stevens-Johnson syndrome, toxic epidermal necrolysis and drug reaction with eosinophilia and systemic symptoms) have been reported with the use of Co-Trimoxazole appearing initially as reddish target-like spots or circular patches often with central blisters on the trunk.
• At the start of treatment, the occurrence of a generalised skin redness with pustules, accompanied by fever, should raise the suspicion of a serious reaction called generalised acute exanthematous pustulosis (AGEP) (see section 4).
• Additional signs to look for include ulcers in the mouth, throat, nose, genitals and conjunctivitis (red and swollen eyes).
• These potentially life-threatening skin rashes are often accompanied by flu-like symptoms. The rash may progress to widespread blistering or peeling of the skin.
• The highest risk for occurrence of serious skin reactions is within the first weeks of treatment.
• If your child has developed Stevens-Johnson syndrome, toxic epidermal necrolysis or drug reaction with eosinophilia and systemic symptoms with the use of Co-Trimoxazole your child must not be re-started on Co-Trimoxazole at any time.
• If your child develops a rash or these skin symptoms, stop giving Co-Trimoxazole, seek urgent advice from a doctor and tell him that your child is taking this medicine.
• Haemophagocytic lymphohistiocytosis
  There have been very rare reports about excessive immune reactions due to a dysregulated activation of white blood cells resulting in inflammations (haemophagocytic lymphohistiocytosis), which can be life-threatening if not diagnosed and treated early. If you experience multiple symptoms such as fever, swollen glands, feeling weak, lightheaded, shortness of breath, bruising, or skin rash simultaneously or with a slight delay, contact your doctor immediately.
• If you develop an unexpected worsening of cough and shortness of breath, inform your doctor immediately.
• If you have been told that your child is at risk for a rare blood disorder called porphyria.
• If they don’t have enough folic acid (a vitamin) in their body - which can make their skin pale and make them feel tired, weak and breathless. This is known as anaemia.
• If they have a disease called glucose-6-phosphate dehydrogenase deficiency, which can cause jaundice or spontaneous destruction of red blood cells.
• If they have a problem with their metabolism called phenylketonuria and are not on a special diet to help their condition.
• If they are underweight or malnourished.
• If you have been told by your child’s doctor that your child has a lot of potassium in their blood. Concomitant administration of Co-Trimoxazole with certain medicines, potassium supplements and food rich in potassium may lead to severe hyperkalaemia (increased potassium blood level). The symptoms of severe hyperkalaemia might include muscle cramps, irregular heart rhythm, diarrhoea, nausea, dizziness or headache.
• If they have a kidney disease.
• If they have severe allergy or bronchial asthma.
• If your child has a severe blood disorder, such as a low number of red blood cells (anaemia), a low number of white blood cells (leucopenia) or a low number of platelets, which may cause bleeding and bruising (thrombocytopenia).

Tell your child’s doctor or pharmacist if your child is taking, has recently taken or might take any other medicines. This is because Co-Trimoxazole can affect the way some medicines work. Also some other medicines can affect the way Co-Trimoxazole works.

In particular tell your child’s doctor or pharmacist if your child is taking any of the following medicines:

• Diuretics (water tablets), which help increase the amount of urine produced.
• Pyrimethamine, used to treat and prevent malaria, and to treat diarrhoea.
• Ciclosporin, used after organ transplant surgeries.
• Blood thinners such as warfarin.
• Phenytoin, used to treat epilepsy (fits).
• Medicines used to treat diabetes, such as glibenclamide, glipizide or tolbutamide (sulphonylureas) and repaglinide.
• Medicines to treat problems with the way the heart beats such as digoxin or procainamide.
• Amantadine, used to treat Parkinson’s disease, multiple sclerosis, flu or shingles.
• Medicines to treat HIV (Human Immunodeficiency Virus), called zidovudine or lamivudine.
• Medicines that can increase the amount of potassium in the blood, such as diuretics (water tablets, which help increase the amount of urine produced, such as spironolactone), steroids (like prednisolone) and digoxin or ACE inhibitors (may be used to treat high blood pressure or some heart problems).
• Azathioprine, may be used in patients following organ transplant or to treat immune system disorders or inflammatory bowel disease .
• Methotrexate, a medicine used to treat certain cancers or certain diseases affecting the immune system.
• Folinic acid.
• Rifampicin, an antibiotic.
• Contraceptive medicines.

Your child should take Co-Trimoxazole with some food or drink. This will stop them feeling sick (nausea) or having diarrhoea. Although it is better to take it with food, they can still take it on an empty stomach.

Make sure your child drinks plenty of fluid such as water while they are taking Co-Trimoxazole.

3.25 g sorbitol in every 5 ml spoonful. If you have been told by your child’s doctor that they cannot tolerate or digest some sugars (has an intolerance to some sugars), contact your child’s doctor before giving this medicinal product to your child.

• A small amount of ethanol (alcohol), less than 100 mg per 5 ml spoonful.
• Methyl hydroxybenzoate, which may cause allergic reactions (possibly delayed).
• Benzoate, which may increase the risk of jaundice in newborn babies.
• Less than 1 mmol sodium (23 mg) per 5 ml, i.e. essentially ‘sodium free’.
