What Magnapen is and what it is used for

Magnapen Capsules contains two active ingredients, ampicillin and flucloxacillin which together are
known as co-fluampicil. Magnapen Capsules are an antibiotic medicine. They belong to the penicillin
group of antibiotics and work by killing bacteria that cause infections.
Magnapen Capsules are used to treat a wide range of infections caused by bacteria. These infections
may affect the chest, ear, nose, throat, skin and soft tissues.
In hospital this medicine may also be used to prevent and treat infections:
 which occur after surgery
 in patients receiving treatment which affects the immune system of the blood (septicaemia)
 associated with difficulties in childbirth (septic abortion (abortion complicated by fever, often
leading to sepsis) and puerperal fever (an infection of the membrane of the uterus following
childbirth or abortion)).

Before you take Magnapen Capsules

Do not take Magnapen Capsules if you:
 know that you are allergic to penicillin, cephalosporins, any other antibiotic or any of the
ingredients contained in Magnapen Capsules (see ‘What Magnapen Capsules contain’ in
section 6)
 have ever had a skin rash or swelling of the face or neck when taking an antibiotic
 have ever had a serious complaint, such as liver problems, when taking an antibiotic.
If any of the above statements apply to you, you should not be given Magnapen Capsules.
Speak to your doctor before taking Magnapen Capsules if you:
 are being treated for kidney or liver problems
 have glandular fever
 are having blood tests because your medicine sometimes causes short-term changes in blood cell


Additional monitoring of kidney and liver function is recommended for patients on prolonged
treatment e.g. osteomyelitis (bone infection) or endocarditis (infection of the muscle around the heart).
If any of the above apply your doctor may decide to change the dose of Magnapen Capsules or
prescribe a different medicine.
Taking other medicines
Taking another medicine while you are taking Magnapen Capsules can affect how it or the other
medicine works. Please inform your doctor or pharmacist if you are taking or have recently taken any
other medicines, even those you may have brought yourself without a prescription.
Tell your doctor if you are using the following medicines (or any other medicines):
 a contraceptive pill as you will need to take extra precautions such as use of a condom
 probenecid and allopurinol, used in the treatment of gout
 or if you are being treated with any other antibiotic
If you are required to have a urine test, please inform your doctor you are taking Magnapen. False
positive results can occur with certain tests for sugar in the urine (e.g. the Fehling’s test) whilst taking
If you have any doubts about whether you should take this medicine then discuss matters with your
