Cetraxal

If you have an infection of the outer ear, your healthcare provider may recommend a medication called Cetraxal. This antibiotic ear drop works by interfering with an enzyme necessary for bacterial growth. Although most people tolerate it well, side effects are possible and may include headache, ear pain, and itching. The drops are usually applied in the affected ear twice a day for seven days.

What Is Cetraxal?

Cetraxal® (ciprofloxacin ear drops) is a prescription ear drop used to treat bacterial infections of the outer ear or ear canal, known medically as acute otitis externa. This type of ear infection is sometimes called "swimmer's ear."

Who Makes Cetraxal?

Cetraxal is made by The Ritedose Corporation for WraSer Pharmaceuticals.
 

How Does It Work?

Cetraxal belongs to a group of drugs called fluoroquinolones, or sometimes "quinolones" for short. Fluoroquinolones are antibiotics used to kill bacteria that cause infections. Cetraxal interferes with a bacterial enzyme called DNA gyrase. This enzyme is needed by the bacteria to make DNA, which is important for the bacteria to multiply.
 

When and How to Use Cetraxal

Some general considerations to keep in mind during treatment with Cetraxal include the following:
 
  • This medication comes in the form of an ear drop. It is normally used in the infected ear twice a day, about 12 hours apart, for seven days.
     
  • Cetraxal comes in a single-use container. This means the contents in each container are enough for one dose. Throw out the container after use, even if it seems like there is still some medicine left in it.
     
  • General steps for using Cetraxal include the following:
     
    • Wash your hands before use.
     
    • You can warm the single-use container in your hands for about a minute if you like. Putting cold ear drops into the ear can sometimes cause dizziness.
     
    • Twist off the top of the container, and throw it away.
     
    • Lie with the infected ear up and empty the entire contents of one container into the ear.
     
    • Stay lying with the infected ear up for at least a minute. This helps the medicine stay in the ear.
     
    • Throw out the empty container.
     
    • If you have an infection in the other ear, repeat the steps using a new Cetraxal container.
 
  • This medication should only be used in the ear. Do not take it by mouth, put it in your nose or eyes, or apply it to your skin.
     
  • Try to keep your ears dry while using this medication. You should not go swimming during Cetraxal treatment unless your healthcare provider tells you it is okay.
     
  • You should begin to feel better within a few days of starting Cetraxal. However, this does not mean your infection is gone. It is important that you finish the full course of this medicine. Stopping treatment too early may cause the infection to return, or lead to antibiotic resistance.
     
  • For the medication to work properly, it must be used as prescribed.
