How does Geriflox work?
- Geriflox capsules contain the active ingredient flucloxacillin. Geriflox belongs to a group of antibiotics called penicillins. It is used to treat infections caused by bacteria.
- Geriflox works by interfering with the ability of bacteria to form cell walls. The cell walls of bacteria are vital for their survival. They keep unwanted substances from entering their cells and stop the contents of their cells from leaking out. Geriflox impairs the bonds that hold the bacterial cell wall together. This allows holes to appear in the cell walls and kills the bacteria.
- Geriflox differs from other penicillin-type antibiotics. When bacteria become resistant to penicillin antibiotics it is because they produce an enzyme called penicillinase. This enzyme breaks down the penicillin and makes it ineffective at killing the bacteria. Geriflox is not affected by this enzyme. This means it is used primarily to treat infections caused by bacteria that are resistant to other penicillin-type antibiotics.
- The types of infection Geriflox is used to treat include: infections affecting the skin and soft tissue (eg boils, cellulitis, impetigo, and infected eczema, ulcers, burns and wounds); bone infections; urinary tract infections; respiratory tract infections (eg pneumonia, sinusitis, lung abcess, pharyngitis, quinsy); meningitis; and blood poisoning (septicaemia). Geriflox is also sometimes used to prevent infections during major surgery, for example bone or heart surgery.
- To make sure the bacteria causing an infection are susceptible to Geriflox your doctor may take a tissue sample, for example a swab from the throat or skin, or a urine or blood sample.
How do I take Geriflox?
- The dose of this medicine and how long it needs to be taken for depends on the type and severity of infection you have, your age, weight and kidney function. Follow the instructions given by your doctor. These will be printed on the dispensing label that your pharmacist has put on the packet of medicine.
- Geriflox is usually taken four times a day (every six hours), but follow the instructions given by your doctor. You should try to space the doses evenly throughout the day.
- Geriflox should be taken on an empty stomach, which means either half an hour to an hour before food or two hours after food.
- The capsules should be swallowed with liquid.
- Unless your doctor tells you otherwise, it is important that you finish the prescribed course of this antibiotic medicine, even if you feel better or it seems the infection has cleared up. Stopping the course early increases the chance that the infection will come back and that the bacteria will grow resistant to the antibiotic.
