amikacin
Amikacin is an aminoglycoside antibiotic that's used to treat several types of bacterial infections in adults and children. It's given as an injection into the veins (IV) or into the muscle (IM) by a healthcare professional. The dosage depends on your age, your weight, and the severity of your infection. Side effects aren't common as long as the level of amikacin in your blood is in a certain range. But they can include diarrhea, nausea, and rash. High amikacin blood levels can lead to more severe risks, such as hearing loss or kidney damage.

Pros and cons of Amikacin
Pros
- Works well to treat many infections caused by Gram-negative bacteria
- Approved for adults and children
Cons
- Requires your care team to draw your blood often to check your amikacin levels and make sure it's working and is safe for you
- Given as an injection
- Possible risk for hearing problems and kidney damage
Pharmacist tips for Amikacin
- Tell your care team about all of the medications you take, especially if you're taking diuretics (water pills) or other antibiotics. These medications can interact with amikacin and raise your risk for kidney damage and hearing problems.
- If your care team says that you don't need to stay in the hospital for treatment, be sure to mark your appointments on your calendar for your doses, any follow-up visits with them, and any lab tests. This will help make sure your amikacin treatment is going well and that the antibiotic is as safe as possible for you. Carefully follow your care team's instructions to help safely fight your infection.
- Your care team might order different tests to keep track of your amikacin treatment. These tests help check your amikacin blood levels, kidney health, and hearing. They're important for your infectious disease specialist to decide whether you need dose adjustments to keep the antibiotic working well for you and to keep you safe from side effects.
- It's possible for amikacin to cause diarrhea. Most times, diarrhea from treatment goes away when you stop taking the antibiotic. But tell your care team right away if you start having watery or bloody diarrhea, fever, fatigue, or stomach cramps anytime during treatment or after stopping amikacin. These can be signs of infectious diarrhea that can be serious and it needs to be treated right away.
- Get medical help right away if you experience any confusion, ringing in the ears, hearing loss, muscle twitching, tingling, or seizure. These could be signs of side effects of the antibiotic that affect your nervous system.
- Contact your care team if you develop other symptoms of an illness or if your symptoms become worse. Amikacin can only treat infections caused by bacteria, so it won't help if you have an infection caused by a virus or fungus.
- It's important to get all of your amikacin doses as instructed and finish your treatment course, even if you feel better. Otherwise, your infection might get worse or become harder to treat.
Risks and warnings for Amikacin
Amikacin can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk of side effects related to the nervous system, including hearing loss
- Risk factors: History of brain, nervous system, or hearing problems | Taking other medications that cause nervous system or hearing problems | Taking too much amikacin | Taking amikacin for too long | Premature and newborn babies | Older age | Dehydration (low fluids in the body)
Amikacin can potentially cause nervous system problems, including dizziness, numbness, tingling, muscle twitching, difficulty breathing, and even seizures. It's also possible for amikacin to cause ringing in the ears or permanent partial or total hearing loss, typically in both ears. Your risk for hearing problems is higher if you're also taking other medications that can cause hearing loss, such as diuretics (e.g., furosemide (Lasix)).
Depending on how long you need amikacin treatment, your care team might test your hearing regularly during treatment. Get medical help right away or contact your care team if you notice changes in your hearing, dizziness, numbness, tingling, or muscle twitching. They can help you manage these effects.
Kidney problems
- Risk factors: History of kidney problems | Taking other medications that cause kidney damage | Taking too much amikacin | Taking amikacin for too long | Premature and newborn babies | Older age | Dehydration (low fluids in the body)
Amikacin can potentially damage the kidneys. Sometimes, kidney damage can cause your body to not make urine as well. Your risk is higher if you're also taking other medications that can harm your kidneys.
Your care team will check your kidney health through urine and blood tests while you're getting treated with amikacin. The infectious disease specialist will adjust your dose or stop treatment if it appears that the antibiotic has affected the kidneys.
To protect your kidneys, your care team will be sure to give you IV fluids when you're getting your amikacin injection. They might also recommend that you stay well hydrated during treatment. Contact your care team if you notice signs or symptoms of kidney problems, such as tiredness, dry and itchy skin, low appetite, urinating less than usual, foamy or bloody urine, or muscle cramps.
Risk of harm to unborn baby
It's possible for aminoglycoside antibiotics like amikacin to cause harm to an unborn baby when it's given during pregnancy. This can include hearing loss. Because of the risk of harm, your care team should be aware of whether you're pregnant before your amikacin treatment starts, if possible. Depending on your infection and your risk factors, the infectious disease specialist might consider a different antibiotic for you.
Serious allergic reaction
- Risk factors: Allergy to sulfites
Serious allergic reactions to amikacin are possible, including life-threatening reactions like facial swelling, shock, and anaphylaxis (e.g., closing of the throat). Call for help right away if you notice hives, difficulty breathing, a choking sensation, swelling around your eyes, or swelling of the lips or tongue while you're getting treated with amikacin.
The amikacin injection contains an ingredient called sulfite. Certain people might be sensitive to sulfite and have an allergic reaction to it. Depending on your reaction, the infectious disease specialist might switch you to another antibiotic.
Diarrhea from Clostridioides difficile infection
Antibiotics, including amikacin, raise your risk of getting infected with a bacteria called Clostridioides difficile (C. diff). Antibiotics change the amount of normal bacteria in your stomach and intestines. This can cause C. diff to overgrow in your gut and lead to an infection that causes diarrhea. This diarrhea can sometimes be life-threatening.
C. diff-related diarrhea is a medical emergency. Fet medical attention right away if you experience rapid heart rate, fever, nausea, foul-smelling diarrhea, bloody stools, or frequent bowel movements (even up to 15 times per day). You'll need to get tested for C. diff infection and get treated, if needed.
Development of drug-resistant bacteria
The infectious disease specialist will closely watch your amikacin treatment to make sure you're taking the antibiotic for the appropriate infection and amount of time. Taking amikacin for any shorter or longer periods of time or taking the antibiotic for other illnesses can raise your risk for developing infections caused by drug-resistant bacteria. This puts you at risk of having a severe and life-threatening infection that might be difficult to treat.
