About levofloxacin

What is levofloxacin used for?

Levofloxacin is a type of antibiotic used to treat bacterial infections such as sinusitis, bröstinfektioner, urine infections, prostatitis, and some skin and soft tissue infections.

It works by killing the bacteria which are the cause of the infection.

Other antibiotics are usually prescribed in preference to levofloxacin. Levofloxacin is reserved for infections which have not improved with other antibiotic treatment. It is also used if other, more preferred, antibiotics cannot be prescribed for some reason.

Levofloxacin is also available as eye drops for the treatment of eye infections. For more information on this use see the leaflet Levofloxacin ögondroppar.

How to take levofloxacin tablets

• Read the information leaflet in the pack before starting, as it explains levofloxacin and its possible side effects.

• Take levofloxacin exactly as your doctor tells you. The usual dose is 500 mg daily, but it may be 250 mg once daily or 500 mg twice daily depending on your infection. Check the label for your correct dose.

• You can take it before or after meals. If taking once a day, take it in the morning. If more than once a day, space doses about 12 hours apart.

• Swallow tablets with water. You can split them along the score line if needed, but do not crush or chew.

• Avoid antacids, iron, or zinc supplements for two hours before and after each dose, as they reduce how well the medicine works.

• If you forget a dose, take it when you remember unless the next dose is due then skip the missed dose. Don’t take two doses at once.

• Finish the full course even if you feel better, unless your doctor tells you to stop. Most courses last 7–14 days. See your doctor if you still feel unwell after finishing the treatment.
