1. WHAT SEPTRIN IS AND WHAT IT IS USED FOR
Septrin is a combination of two different antibiotics called sulfamethoxazole and trimethoprim, which is used to treat
infections caused by certain bacteria. This medicine combination is also named as co-trimoxazole. Like all
antibiotics, Septrin only works against some types of bacteria. This means that it is only suitable for treating some
types of infections. Septrin can be used to treat or prevent:
• Lung infections (pneumonia or PJP) caused by a bacteria called Pneumocystis jiroveci (previously known as
Pneumocystis carinii or PCP).
• Infections caused by a bacteria called Toxoplasma (toxoplasmosis).
Septrin can be used to treat:
• Urinary bladder or urinary tract infections (water infections)
• Respiratory tract infections such as bronchitis
• Ear infections such as otitis media
• An infection called nocardiosis which can affect the lungs, skin and brain.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE SEPTRIN
Do not take Septrin if:
• You are allergic (hypersensitive) to sulfamethoxazole, trimethoprim or co-trimoxazole or any of the other
ingredients of Septrin (see section 6: Contents of the pack and other information).
• You are allergic to sulphonamide medicines. Examples include sulphonylureas (such as gliclazide and
glibenclamide) or thiazide diuretics (such as bendroflumethiazide - a water tablet).
• You have severe liver or kidney problems.
• You have ever had a problem with your blood causing bruises or bleeding (thrombocytopenia).
• You have been told that you have a rare blood problem called porphyria, which can affect your skin or nervous
system.
If it is for your child, Septrin should not be given if they are less than 6 weeks old or were premature unless it is for
the treatment or prevention of PJP. In this case, Septrin should not be given if they are less than 4 weeks old.
If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking Septrin.
