Uses

What is intrazoline used for?

Intrazoline is commonly used to treat many kinds of bacterial infections, including severe or life-threatening forms, involving the lung, bone, joint, stomach, blood, heart valve and urinary tract. Intrazoline will not treat a viral infection such as the flu or a common cold.

Intrazoline may be used for other purposes, ask your doctor for more information.

How should I take intrazoline?

Intrazoline is injected into a muscle or into a vein through an IV. You may be shown how to use injections at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles, syringes, IV tubing, and other items used to inject the medicine.

Intrazoline must be mixed with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medicine.

Shake the mixture well just before you measure a dose. Do not use the medicine if it has changed colors or has particles in it. Call your doctor for a new prescription.

Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use 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.

Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics.
