Tavanic tablets contain the active ingredient levofloxacin, which is a type of medicine called a quinolone antibiotic. Antibiotics are used to treat infections caused by bacteria.

How does Tavanic work?

  • Tavanic works by killing the bacteria that are causing an infection. It does this by entering the bacterial cells and inhibiting a bacterial enzyme called DNA-gyrase. This enzyme is involved in replicating and repairing the genetic material (DNA) of the bacteria. If this enzyme doesn't work, the bacteria cannot reproduce or repair themselves and this kills the bacteria.
  • Tavanic is effective against a large number of bacteria.
It is used to treat a range of infections, including infections of the chest, urinary tract and skin.
  • To make sure the bacteria causing an infection are susceptible to Tavanic, your doctor may take a tissue sample, for example a swab from the throat or skin, or a urine or blood sample.

    What is Tavanic used for?

    How do I take it?

    • The dose of this medicine, how often it needs to be taken and how long it needs to be taken for depends on the type and severity of infection you have and your 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.
    • Tavanic tablets are usually taken once or twice a day. The tablets should be swallowed without chewing or crushing, however the tablets are scored and can be broken. They can be taken either with or without food. Try to take them at regular intervals.
    • You should not take iron tablets or indigestion remedies at the same time of day as this medicine, because these can reduce the absorption of the antibiotic from the gut. If you need to take iron tablets or indigestion remedies they should be taken at least two hours before or after taking this medicine.
    • 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.
