Amikacin Sulfate Injection (patient information)

IMPORTANT WARNING
Amikacin can cause severe hearing and kidney problems. Before administering amikacin, tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially diuretics ('water pills'), cisplatin (Platinol), amphotericin (Amphotec, Fungizone), other antibiotics, and vitamins.

If you experience any of the following symptoms, call your health care provider immediately: dizziness, vertigo, ringing in the ears, hearing loss, numbness, muscle twitching or weakness, difficulty breathing, decreased urination, rash, itching, or sore throat.

About your treatment
Your doctor has ordered amikacin, an antibiotic, to help treat your infection. The drug will be either injected into a large muscle (such as your buttock or hip) or added to intravenous fluid that will drip through a needle or catheter placed in your vein for at least 30 minutes, one to three times a day.

Amikacin eliminates bacteria that cause many kinds of infections, including lung, skin, bone, joint, stomach, blood, and urinary tract infections. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Your health care provider (doctor, nurse, or pharmacist) may measure the effectiveness and side effects of your treatment using laboratory tests and physical examinations. It is important to keep all appointments with your doctor and the laboratory. The length of treatment depends on how your infection and symptoms respond to the medication.

Precautions
Before administering amikacin:


 * tell your doctor and pharmacist if you are allergic to amikacin, gentamicin (Garamycin), kanamycin (Kantrex), neomycin, netilmicin (Netromycin), streptomycin, tobramycin (Nebcin), or any other drugs.
 * tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially diuretics ('water pills'), cisplatin (Platinol), amphotericin (Amphotec, Fungizone), other antibiotics, and vitamins.
 * tell your doctor if you have or have ever had kidney disease, vertigo, hearing loss, ringing in the ears, myasthenia gravis, or Parkinson's disease.
 * tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking amikacin, call your doctor immediately. Amikacin can harm the fetus.

Administering your medication
Before you administer amikacin, look at the solution closely. It should be clear and free of floating material. Gently squeeze the bag or observe the solution container to make sure there are no leaks. Do not use the solution if it is discolored, if it contains particles, or if the bag or container leaks. Use a new solution, but show the damaged one to your health care provider.

It is important that you use your medication exactly as directed. Do not stop your therapy on your own for any reason because your infection could worsen and result in hospitalization. Do not change your dosing schedule without talking to your health care provider. Your health care provider may tell you to stop your infusion if you have a mechanical problem (such as a blockage in the tubing, needle, or catheter); if you have to stop an infusion, call your health care provider immediately so your therapy can continue.

Side effects
Amikacin occasionally causes side effects. To reduce this risk, your health care provider may adjust your dose based on your blood test results. Follow the directions in the IMPORTANT WARNING section for symptoms listed there and tell your health care provider if any of the following symptoms are severe or do not go away:


 * upset stomach
 * vomiting
 * fatigue
 * pale skin

Storing your medication
Your health care provider probably will give you a several-day supply of amikacin at a time. If you are receiving amikacin intravenously (in your vein), you probably will be told to store it in the refrigerator or freezer. Take your next dose from the refrigerator 1 hour before using it; place it in a clean, dry area to allow it to warm to room temperature. If you are told to store additional amikacin in the freezer, always move a 24-hour supply to the refrigerator for the next day's use. Do not refreeze medications.

If you are receiving amikacin intramuscularly (in your muscle), your health care provider will tell you how to store it properly.

Store your medication only as directed. Make sure you understand what you need to store your medication properly.

Keep your supplies in a clean, dry place when you are not using them, and keep all medications and supplies out of reach of children. Your health care provider will tell you how to throw away used needles, syringes, tubing, and containers to avoid accidental injury.

Signs of infection
If you are receiving amikacin in your vein or under your skin, you need to know the symptoms of a catheter-related infection (an infection where the needle enters your vein or skin). If you experience any of these effects near your intravenous catheter, tell your health care provider as soon as possible:


 * tenderness
 * warmth
 * irritation
 * drainage
 * redness
 * swelling
 * pain
