Plazomicin injection is used to treat serious urinary tract infections, including kidney infections, that are caused by bacteria. Plazomicin injection is in a class of medications called aminoglycoside antibiotics. It works by killing bacteria.

Antibiotics such as plazomicin injection will not work for colds, flu, or other viral infections. Taking or using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

Plazomicin injection may cause serious kidney problems. Kidney problems may occur more often in older adults. Tell your doctor if you have or have ever had kidney disease. The risk that you will develop serious kidney problems is greater if you are taking or using certain medications. Tell your doctor and pharmacist what other prescription and nonprescription medications you are taking. If you experience any of the following symptoms, call your doctor immediately: decreased urination; swelling of the face, arms, hands, feet, ankles, or lower legs; or unusual tiredness or weakness.

Plazomicin injection may cause serious hearing problems. Hearing loss may be permanent in some cases. Tell your doctor if you or a family member have hearing loss not related to normal aging or have a history of hearing loss due to use of any medication, or if you have or have ever had dizziness, vertigo, hearing loss, or ringing in the ears. If you experience any of the following symptoms during or after your treatment, call your doctor immediately: hearing loss, roaring or ringing in the ears, loss of balance, or dizziness.

Plazomicin may cause muscle or nerve problems. Tell your doctor if you have or have ever had a neuromuscular disorder such as myasthenia gravis (MG; a disorder of the nervous system that causes muscle weakness) or Parkinson's disease. If you experience any of the following symptoms, call your doctor immediately: burning, tingling, or numbness in the hands, arms, feet, or legs; muscle twitching or weakness; or seizures.

If you are having surgery, including dental surgery, tell the doctor or dentist that you are using plazomicin injection.

Tell your doctor if you are pregnant or plan to become pregnant. If you become pregnant while using plazomicin injection, call your doctor immediately. Plazomicin 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 plazomicin.

Plazomicin injection comes as a liquid to be injected intravenously (into a vein). When plazomicin is injected intravenously, it is usually infused (injected slowly) over a period of 30 minutes once daily. The length of your treatment is usually 4 to 7 days.

You may receive plazomicin injection in a hospital or you may administer the medication at home. If you will be receiving plazomicin 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 plazomicin injection. If your symptoms do not improve or get worse, tell your doctor.

Use plazomicin injection until you finish the prescription, even if you feel better. If you stop using plazomicin injection too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.

Before using plazomicin injection,

• tell your doctor and pharmacist if you are allergic to plazomicin injection; other aminoglycoside antibiotics such as amikacin, gentamicin, neomycin, streptomycin, or tobramycin; any other medications; or any of the ingredients in plazomicin injection.
