The risk that you will develop serious kidney, hearing, or other problems is greater if you are taking certain medications. Tell your doctor and pharmacist if you are taking acyclovir (Zovirax, Sitavig); amphotericin (Abelcet, Ambisome, Amphotec); capreomycin (Capastat); certain cephalosporin antibiotics such as cefazolin (Ancef, Kefzol), cefixime (Suprax), or cephalexin (Keflex); cisplatin; colistin (Coly-Mycin S); cyclosporine (Gengraf, Neoral, Restasis, Sandimmune); diuretics ('water pills') such as bumetanide, ethacrynic acid (Edecrin), furosemide (Lasix), or torsemide (Demadex). other aminoglycoside antibiotics such as amikacin, gentamicin, kanamycin, neomycin (Neo-Fradin), and streptomycin; pentamidine (Nebupent, Pentam); polymyxin B; or vancomycin (Vanocin). Your doctor may not want you to receive tobramycin injection.
Tell your doctor if you are pregnant or plan to become pregnant. If you become pregnant while using tobramycin injection, call your doctor immediately. Tobramycin may harm the fetus.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain tests, including hearing tests, before and during treatment to check your body's response to tobramycin.
WHY is this medicine prescribed?
Tobramycin injection is used to treat certain serious infections that are caused by bacteria such as meningitis (infection of the membranes that surround the brain and spinal cord) and infections of the blood, abdomen (stomach area), lungs, skin, bones, joints, and urinary tract. Tobramycin injection is in a class of medications called aminoglycoside antibiotics. It works by killing bacteria.
Antibiotics such as tobramycin injection will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
HOW should this medicine be used?
Tobramycin injection comes as a liquid to be injected intravenously (into a vein) or intramuscularly (into a muscle). When tobramycin is injected intravenously, it is usually infused (injected slowly) over a period of 20 to 60 minutes once every 6 or 8 hours. The length of your treatment depends on the type of infection you have.
You may receive tobramycin injection in a hospital or you may administer the medication at home. If you will be receiving tobramycin injection at home, your healthcare provider will show you how to use the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions.
You should begin to feel better during the first few days of treatment with tobramycin injection. If your symptoms do not improve or get worse, call your doctor.
Use tobramycin injection until you finish the prescription, even if you feel better. If you stop using tobramycin injection too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
