Ciriax is used to treat different types of bacterial infections. It may also be used to prevent or slow anthrax after exposure. Ciriax is an antibiotic in a group of drugs called fluoroquinolones. It fights bacteria in the body. It works by stopping the production of essential proteins needed by the bacteria to survive. Ciriax will not treat a viral infection such as the common cold or flu.
Take Ciriax exactly as it was prescribed for you.
- Do not take it in larger doses or for longer than recommended by your doctor. Follow the directions on your prescription label.
- Take Ciriax with a full glass of water (8 ounces). Drink several extra glasses of fluid each day while you are taking Ciriax.
- Do not crush, chew or break the tablet. Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking the pill would cause too much of the drug to be released at one time.
- Ciriax may be taken with or without food, but take it at the same time each day.
- Do not take Ciriax with dairy products such as milk or yogurt, or with calcium-fortified juice. You may eat or drink these products as part of a regular meal, but do not use them alone when taking Ciriax. They could make the medication less effective.
- Take this medication for as many days as it has been prescribed for you even if you begin to feel better. Your symptoms may get better before the infection is completely treated.
- If you miss a dose of Ciriax, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.
Ask your health care provider any questions you may have about how to use Ciriax.
Store Ciriax at room temperature away from moisture and heat. Keep Ciriax out of the reach of children and away from pets.

Important Ciriax Safety Information
- Ciriax may cause drowsiness, dizziness, blurred vision, or lightheadedness. These effects may be worse if you take it with alcohol or certain medicines. Use Ciriax with caution. Do not drive or perform other possible unsafe tasks until you know how you react to it.
- Be sure to use Ciriax for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The bacteria could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.
- Long-term or repeated use of Ciriax may cause a second infection. Tell your doctor if signs of a second infection occur. Your medicine may need to be changed to treat this.
- Ciriax only works against bacteria; it does not treat viral infections (eg, the common cold).
- Avoid large amounts of food or drink that have caffeine (eg, coffee, tea, cocoa, cola, chocolate).
- Tell your doctor right away if you experience pain or swelling of a tendon or weakness or loss of use of a joint area. Rest the area and avoid exercise until further instruction from your doctor.
- Diabetes patients - Ciriax may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
- Ciriax may cause you to become sunburned more easily. Avoid the sun, sunlamps, or tanning booths until you know how you react to Ciriax. Use a sunscreen or wear protective clothing if you must be outside for more than a short time.
- Mild diarrhea is common with antibiotic use. However, a more serious form of diarrhea (pseudomembranous colitis) may rarely occur. This may develop while you use the antibiotic or within several months after you stop using it. Contact your doctor right away if stomach pain or cramps, severe diarrhea, or bloody stools occur. Do not treat diarrhea without first checking with your doctor.
- Use Ciriax with caution in the elderly; they may be more sensitive to its effects (eg, tendon problems), especially if they take corticosteroids (eg, prednisone). They may also be more sensitive to other effects (eg, irregular heartbeat).
- Ciriax should be used with extreme caution in children younger 18 years; they may be more sensitive to its effects, especially joint and tendon problems.
