Pros
- Good at treating serious skin and bloodstream infections caused by Staphylococcus bacteria ("staph" infections)
- Can use to treat children as young as 1 year of age
- Given once per day
Cons
- Needs to be given as an IV infusion over a 30-to-60 minute period

Pharmacist tips for Daptomycin (Cubicin)
- Get medical help if you experience muscle pain or weakness, especially if you also have a fever or feel extremely tired. This can be a sign of rare, but serious muscle breakdown called rhabdomyolysis. Let your provider know if you're taking a statin (a common cholesterol medication) because this can raise your risk.
- Call for emergency help right away if you experience a rash, itchy skin, trouble breathing, or swelling in your face or mouth. These are signs of a severe allergic reaction.
- Daptomycin (Cubicin) can cause diarrhea. It typically goes away when you stop taking the antibiotic. But call your provider as soon as possible if you start having watery or bloody diarrhea, fever, fatigue, or stomach cramps anytime during treatment or after stopping daptomycin (Cubicin). These can be signs of infectious diarrhea that can be serious and needs to be treated right away.
- Let your provider know if you're taking warfarin (Coumadin) because daptomycin (Cubicin) can affect your INR readings. The antibiotic can cause falsely high INR levels.
- Contact your provider if you develop other symptoms of an illness or if your symptoms become worse. Daptomycin (Cubicin) can only treat infections caused by bacteria and won't help if you have an infection caused by a virus or fungus.
Tips for using daptomycin (Cubicin) at home (if instructed by your provider):
- If you need treatment with daptomycin (Cubicin) for a long time, it's possible that your provider might let you take the medication at home. If so, make sure to follow your provider's instructions carefully so you use daptomycin (Cubicin) properly and safely. Your provider might instruct you to use vials of the medication that need to be mixed and prepared or premixed bags that are ready to use.
- If you're using daptomycin (Cubicin) at home for long-term treatment, you should set a reminder for your doses. It's important to take all of your doses of daptomycin (Cubicin) and finish your treatment course, even if you feel better. Otherwise, your infection might get worse or become harder to treat.
- Write down any scheduled provider visits and blood work appointments on your calendar. This will help your provider make sure that daptomycin (Cubicin) is treating your infection and that it's safe for you.
Common questions about Daptomycin (Cubicin)
Yes, daptomycin (Cubicin) is one of the first-choice options for treating certain infections caused by methicillin-resistant Staphylococcus aureus (also known as MRSA). MRSA is a bacterial infection that's hard to treat since many antibiotics don't work against it. In addition to MRSA, daptomycin (Cubicin) can also treat some other types of bacteria, such as those from the Enterococci and Streptococci families.
Daptomycin (Cubicin) and vancomycin are similar antibiotics in that they both treat serious infections caused by similar types of bacteria. One medication isn't necessarily "stronger" than the other. But daptomycin (Cubicin) is a good choice when vancomycin can't be used. One example is for infections caused by resistant bacteria that vancomycin won't work to fight against (e.g., vancomycin-resistant Enterococci (VRE)). Another difference includes how often the medications are given (once per day for daptomycin (Cubicin), every 6 to 24 hours for vancomycin). In addition, daptomycin (Cubicin) might cause less kidney injury than vancomycin.
No, daptomycin (Cubicin) shouldn't be used to treat pneumonia (lung infection). This is because daptomycin (Cubicin) gets blocked by surfactant in the lungs, which is a collection of protein and lipids (fat) that helps your lungs work. This means that daptomycin (Cubicin) doesn't work well in the lungs to treat pneumonia. Your healthcare team will choose a different antibiotic that will work better to treat your lung infection.
Daptomycin (Cubicin) can be harmful to the kidneys, but it's rare. Though uncommon, daptomycin (Cubicin) can cause rhabdomyolysis, a life-threatening muscle problem that can then lead to kidney problems. Since the kidneys help get rid of daptomycin (Cubicin) from the body, people with kidney problems typically need a lower dose of the antibiotic. This helps prevent the medication from building up in the body and lower the risk of side effects. Your provider will check your kidney function while you're getting treated with daptomycin (Cubicin) to make sure it's not harming your kidneys and to see whether your dose needs to be adjusted to keep you safe.
Yes, you can safely take daptomycin (Cubicin) if you're allergic to penicillin. The two medications are different types of antibiotics: daptomycin (Cubicin) is a cyclic lipopeptide antibiotic, whereas penicillin is a beta-lactam antibiotic. They work differently to get rid of bacteria and have completely different chemical structures. If you're allergic to one of these antibiotics, it doesn't mean you'll be allergic to the other.

Risks and warnings for Daptomycin (Cubicin)
Daptomycin (Cubicin) 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.
Severe allergic reactions
Severe allergic reactions to daptomycin (Cubicin) are possible. These can include life-threatening reactions like facial swelling and anaphylaxis (e.g., closing of the throat). Daptomycin (Cubicin) can also cause drug reaction with eosinophilia and systemic symptoms (DRESS), which can look like fever, rash, and swollen lymph nodes. Get medical help right away if you notice any of these symptoms to get appropriate treatment.
Muscle pain and severe muscle damage
- Risk factors: Kidney problems | Taking other medications (e.g., statins) that can also cause muscle problems
Daptomycin (Cubicin) can cause a rare, but serious and life-threatening muscle problem called rhabdomyolysis. Your risk is higher if you take medications that cause muscle problems (e.g., statins). Your provider will regularly check your creatine phosphokinase (CPK) blood levels, which measures possible muscle damage. Your provider will also regularly check your kidney function during treatment because severe muscle damage can lead to kidney problems. Stop daptomycin (Cubicin) and get medical attention right away if you notice any of symptoms of rhabdomyolysis, such as severe muscle pain, dark-colored urine, weakness, and tiredness.
Kidney damage
Although rare, daptomycin (Cubicin) can cause kidney damage. This can make your kidneys not work as well as they should. Daptomycin (Cubicin) can also cause muscle damage that leads to kidney problems. Your provider will monitor your kidney health during your daptomycin (Cubicin) treatment course.
Pneumonia
Some people taking daptomycin (Cubicin) have had a rare type of pneumonia called eosinophilic pneumonia. In general, it can happen 2 to 4 weeks after starting daptomycin (Cubicin). If this happens, it means that you probably can't get treated with this antibiotic anymore. Call your nurse right away if you have a high fever, chest pain, cough, or trouble breathing.
Nerve damage
Daptomycin (Cubicin) can rarely cause nerve pain. Symptoms include burning, tingling, numbness, pain, or not being able to tolerate heat or coldness in parts of your body. Tell your provider if you have any of these symptoms because you might need to stop using daptomycin (Cubicin).
Diarrhea from Clostridioides difficile infection
Antibiotics, including daptomycin (Cubicin), raise your risk of getting infected with a bacteria called Clostridioides difficile (C. diff). This infection can cause diarrhea that can sometimes be life-threatening. 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.
This type of infectious diarrhea is different than the diarrhea you might get as a possible side effect of daptomycin (Cubicin). C. diff-related diarrhea can cause rapid heart rate, fever, nausea, foul-smelling diarrhea, bloody stools, or frequent bowel movements (even up to 15 times per day). This is a medical emergency, so get medical attention right away if you experience any of these symptoms. You'll get tested for C. diff infection and receive treatment, if needed.
Development of drug-resistant bacteria
Your provider will monitor your treatment with daptomycin (Cubicin) to make sure you're taking the antibiotic for the appropriate infection and amount of time. Using daptomycin (Cubicin) for a shorter period of time than recommended or taking the medication for other illnesses can raise your risk for your infection to become more serious and harder to treat.
Daptomycin (Cubicin) dosage
Typical dosage for Daptomycin (Cubicin)
Daptomycin (Cubicin) is given as an injection into the veins (IV) by a provider in a healthcare setting (e.g., hospital, office, nursing home). The injection is typically given as an infusion that takes 30 minutes to an hour. But it can also be given as a quick injection over a 2-minute period for adults only.
Your dose is based on your body weight and kidney function. The dose and length of treatment also depends on what type of infection you have and how serious it is. Your provider will determine the right dose and length of treatment for you.
For most infections, the general dosage is as follows:
Skin and soft tissue infections
- Adults: The typical dose is 4 mg/kg IV once daily for 7 to 14 days.
- Children ages 1 to 17 years: The typical dose is 5 mg/kg to 10 mg/kg IV once daily for up to 14 days.
Bloodstream infections (caused by Staphylococcus aureus or "staph")
- Adults: The typical dose is 6 mg/kg IV once daily for 2 to 6 weeks.
- Children ages 1 to 17 years: The typical dose is 7 mg/kg to 12 mg/kg IV once daily for up to 6 weeks.
Interactions between Daptomycin (Cubicin) and other drugs
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are receiving this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
