Ampicillin and sulbactam is a combination medicine used to treat many different types of infections caused by bacteria.

Ampicillin and sulbactam may also be used for purposes not listed in this medication guide.

You should not use this medicine if you are allergic to ampicillin or sulbactam, or if you have ever had

• a severe allergic reaction to any type of penicillin or cephalosporin antibiotic; or
• liver problems (hepatitis or jaundice) while using ampicillin and sulbactam.

Tell your doctor if you have ever had:

• liver disease;
• mononucleosis (also called "mono");

Do not give this medicine to a child without medical advice.

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

Ampicillin and sulbactam is injected into a muscle, or given as an infusion into a vein. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.

Ampicillin and sulbactam must be mixed with a liquid (diluent) before using it. When using injections by yourself, be sure you understand how to properly mix and store the medicine.

After mixing this medicine, you will need to use it within a certain number of hours. This will depend on the diluent and how you store the mixture (at cool room temperature, or in a refrigerator).

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.

This medicine is usually given every 6 hours for 14 days. Follow your doctor's dosing instructions very carefully.

Use this medicine 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. Ampicillin and sulbactam will not treat a viral infection such as the flu or a common cold.

You may need frequent blood tests to check your liver function.

This medicine can affect the results of certain lab tests for glucose (sugar) in the urine. Tell any doctor who treats you that you are using ampicillin and sulbactam.

Store unmixed ampicillin and sulbactam at room temperature away from moisture and heat.

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.

Use the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not use two doses at one time.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Overdose may cause seizure (convulsions).

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, call your doctor before using anti-diarrhea medicine.

Get emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

Call your doctor at once if you have:

• severe stomach pain, diarrhea that is watery or bloody (even if it occurs months after your last dose);
