How does this medication work? What will it do for me?

Fusidic acid belongs to the class of medications called antibiotics. It is used to treat eye infections caused by bacteria that are sensitive to fusidic acid.

Fusdic acid works by preventing the bacteria from reproducing, causing the number of live bacteria to decrease, until there are no more.

Do not wear contact lenses for the time that you are using fusidic acid eye drops. Wearing contact lenses while you have an eye infection may cause eye damage. Some ingredients in eye drops can build up on the lenses, ruining the lens.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Contact lenses: Wearing contact lenses while treating an eye infection may cause permanent damage to your eyes. The preservative in many eye medications can build up on the lenses and permanently damage the lenses. If you wear contact lenses, sterilize or replace your current lenses and wear glasses until the infection has completely cleared.

Overgrowth of organisms: Prolonged or repeated use of fusidic acid may result in an overgrowth of bacteria or fungi and organisms that are not killed by the medication. This can cause other infections to develop. If eye irritation, redness, or discomfort gets worse or does not clear in 7 days, contact your doctor as soon as possible.

Pregnancy: There are no studies that determine the safety of using fusidic acid during pregnancy. This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: This medication passes into breast milk when taken by mouth. It is not clear if enough medication from the eye drop form would pass into breast milk to become a problem. If you are a breast-feeding mother and are taking fusidic acid, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using this medication have not been established for children less than 2 years old.

What other drugs could interact with this medication?

Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them. Depending on your specific circumstances, your doctor may want you to:

  • stop taking one of the medications,
  • change one of the medications to another,
  • change how you are taking one or both of the medications, or
  • leave everything as is.
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
