Before taking this medicine

You should not use this medicine if you are allergic to Totacillin-N or to any other penicillin antibiotic, such as amoxicillin (Amoxil, Augmentin, Moxatag, and others), carbenicillin, dicloxacillin, or penicillin.

To make sure Totacillin-N is safe for you, tell your doctor if you have:

• allergies to any foods or drugs;

• an allergy to a cephalosporin antibiotic, such as cefdinir (Omnicef), cefprozil (Cefzil), cefuroxime (Ceftin), cephalexin (Keflex), and others; or

This medicine is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

Totacillin-N can make birth control pills less effective. Ask your doctor about using non hormonal birth control (condom, diaphragm with spermicide) to prevent pregnancy.

Ampicillin can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

How is Totacillin-N given?

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

You may need to mix Totacillin-N 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. You should use the injection as soon as possible after mixing it.

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.

If you are being treated for gonorrhea, your doctor may also have you tested for syphilis, another sexually transmitted disease.

Your doctor may switch you from Totacillin-N to an oral form of this medicine. 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. This medicine will not treat a viral infection such as the flu or a common cold.

If you use this medicine long-term, you may need frequent medical tests.

Totacillin-N can cause unusual results with certain lab tests for glucose (sugar) in the urine. Tell any doctor who treats you that you are using this medicine.

Store unmixed Totacillin-N at room temperature away from moisture and heat.

After mixing your medicine, you will need to use it within a certain number of hours. This will depend on the diluent used, and whether the mixture is stored at room temperature or in a refrigerator. Carefully follow the mixing and storage instructions provided with your medicine. Ask your pharmacist if you have questions.

What happens if I miss a dose?

Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

What happens if I overdose?

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

What should I avoid while receiving Totacillin-N?

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. Do not use anti-diarrhea medicine unless your doctor tells you to.

What other drugs will affect Totacillin-N?

Other drugs may interact with ampicillin, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using.
