Amikacin 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. Amikacin injection is in a class of medications called aminoglycoside antibiotics. It works by killing bacteria.

Antibiotics such as amikacin 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.

Amikacin may cause serious kidney problems. Kidney problems may occur more often in older people or in people that are dehydrated. Tell your doctor if you have or have ever had kidney disease. 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.

Amikacin may cause serious hearing problems. Hearing problems may occur more often in older people or in people that are dehydrated. 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 roaring or ringing in the ears. If you experience any of the following symptoms, call your doctor immediately: hearing loss, roaring or ringing in the ears, or dizziness.

Amikacin may cause nerve problems. Tell your doctor if you have or have ever had burning, tingling, or numbness in the hands, arms, feet, or legs; muscle twitching or weakness; or seizures.

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 what other prescription and nonprescription medications you are taking.

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

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 amikacin.

Amikacin injection comes as a liquid to be injected intravenously (into a vein) or intramuscularly (into a muscle) every 8 or 12 hours (two or three times a day). When amikacin is injected intravenously, it is usually infused (injected slowly) over a period of 30 to 60 minutes. The length of your treatment depends on the type of infection you have.

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

Use amikacin injection until you finish the prescription, even if you feel better. If you stop using amikacin 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.

Before receiving amikacin injection,

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