What does it do?

Ciprofloxacin is an antibiotic used to treat and prevent bacterial infections.

How should you take it?

Take ciprofloxacin regularly as directed with a glass of water. You can take it with or without food, but not with milk or yoghurt. Taking it with milk or yoghurt may stop ciprofloxacin from working.
Keep taking it until the course is finished, even when you start to feel better.

What if you forget a dose?

Take the missed dose as soon as possible and continue as directed.

Can you take other medicines?

Some medicines available without a prescription may react with ciprofloxacin including:

  • products containing aluminium, calcium, iron, magnesium or zinc, such as antacids (e.g. Mylanta®) or multivitamins

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
