Syrex (flush)

Syrex is the chemical name for salt. This medicine can reduce certain types of bacteria.

Syrex is used to clean out an intravenous (IV) catheter, which helps stop it from getting blocked and removes any medicine that may be left in the catheter area after you have received an IV infusion.

Syrex may also be used for other reasons that are not listed in this medication guide.

Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or more often than recommended.

You will use Syrex each time you use your IV catheter. Follow your doctor's instructions about how many times per day to use the flush.

Before using the flush, check the solution container to make sure there are no leaks. Do not use the medication if it has changed colors or has particles in it. Call your doctor for a new prescription.

Call your doctor or tell your caregivers if your catheter, needle, or IV tubing becomes blocked or if the flush or IV medicine is not flowing normally.

Throw away used needles in a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.

Store Syrex at room temperature away from moisture and heat. Keep all of your catheter flush supplies in a clean dry place when not in use.

Follow all instructions on your medicine label and package. Inform each of your healthcare providers about all your medical conditions, allergies, and all medicines you are using.

Before using Syrex, inform your doctor if you are allergic to any medications.

Get emergency medical help if you notice signs of an allergic reaction, such as hives, trouble breathing, or swelling of your face, lips, tongue, or throat.

Stop using Syrex and contact your doctor immediately if you experience any of these side effects while using the flush:

• severe irritation;
• swelling;
• warmth;
• redness;
• oozing; or
• pain.

Common side effects of Syrex may include:

• a cold feeling or mild burning; or
• mild irritation around the catheter.

This is not a complete list of side effects, and others may happen. Call your doctor for advice about side effects. You can report side effects to the FDA at 1-800-FDA-1088.

If you flush your catheter each time you use it, you are less likely to miss a dose.

An overdose of Syrex (flush) is unlikely to happen.

Follow your doctor's instructions regarding any limits on food, drinks, or activities.

It is unlikely that other medications you take by mouth or through injection will affect Syrex when used to flush your catheter. However, many medications can interact with one another. Inform all your health care providers about every medicine you are using, including prescription and over-the-counter medicines, vitamins, and herbal products.
