How to use Zosyn

Zosyn is given as an IV infusion into a vein. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of needles, IV tubing, and other items used.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.

Prepare an injection only when you are ready to give it. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.

Use Zosyn for the full prescribed length of time, even if your symptoms quickly improve. Skipping doses can increase your risk of infection that is resistant to medication. Zosyn will not treat a viral infection such as the flu or a common cold.

You may need frequent blood tests.

This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are using Zosyn.

Medicine mixed in a syringe can be stored in a refrigerator for up to 48 hours. Mixed medication in an IV bag can also be stored in the refrigerator for up to 7 days. Do not freeze. Throw away any unused mixture that has not been used within these times.

Single-dose vials should be used immediately after reconstitution. Discard any unused portion after 24 hours if stored at room temperature, or after 48 hours if stored at refrigerated temperature.

IV bags must be used within 24 hours at room temperature and up to one week if refrigerated.

Mixed medicine in an infusion pump must be used within 12 hours if you keep it at room temperature.

If your medicine is frozen when you receive it, store the medicine container in a freezer until you are ready to prepare your dose.

You may thaw frozen medicine either in a refrigerator or at room temperature. Do not heat the medicine under hot water or in a microwave.

Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.

Do not freeze. Throw away any unused mixture that has not been used within these times.

Warnings

You should not use Zosyn if you have ever had an allergic reaction to certain antibiotics (especially a penicillin antibiotic).

Before using Zosyn tell your doctor if you have kidney disease, a bleeding or blood clotting disorder, low levels of potassium in your blood, cystic fibrosis, a history of allergies, if you are on a low-salt diet, or if you are allergic to a cephalosporin antibiotic such as cefdinir (Omnicef), cefprozil (Cefzil), cefuroxime (Ceftin), cephalexin (Keflex), and others.

Use Zosyn 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. Zosyn will not treat a viral infection such as the common cold or flu.

Zosyn may cause bleeding, especially in people with kidney disease or using certain medicines. Tell your doctor if you are using any medication to prevent blood clots such as alteplase (Activase), bivalirudin (Angiomax), clopidogrel (Plavix), dabigatran (Pradaxa), dipyridamole (Persantine, Aggrenox), enoxaparin (Lovenox), fondaparinux (Arixtra), heparin, tenecteplase (TNKase), ticlopidine (Ticlid), tinzaparin (Innohep), warfarin (Coumadin, Jantoven), and others.

What other drugs will affect Zosyn

Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.

Other drugs may interact with piperacillin and tazobactam, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.
