What is daptomycin?
Daptomycin is an antibiotic that fights bacteria in the body.
Daptomycin is used to treat bacterial infections of the skin and underlying tissues, and infections that have entered the bloodstream.
Daptomycin is used in cases of complicated infections, including MRSA or "super bug" infections. MRSA stands for methicillin-resistant Staphylococcus aureus.
Daptomycin may also be used for purposes not listed in this medication guide.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

kidney disease; or

How should I use daptomycin?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Daptomycin is injected into a vein through an IV. You may be shown how to use an IV at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of needles, IV tubing, and other items used.
Daptomycin must be given slowly, and the IV infusion can take 2 to 30 minutes to complete. When giving this medicine to a child or teenager, the infusion is even slower (30 to 60 minutes).
Use this medicine for the full prescribed length of time. Some infections must be treated for up to 6 weeks. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Daptomycin will not treat a viral infection such as the flu or a common cold.
Call your doctor if your symptoms do not improve, or if they get worse.
Daptomycin is a powder medicine that must be mixed with a liquid (diluent) before using it. If you are using the injections at home, be sure you understand how to properly mix and store the medication.
Do not shake the medication bottle or you may ruin the medicine. Gently swirl the medicine when mixing. Prepare your dose only when you are ready to give an injection. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.
Each single-use vial (bottle) of this medicine is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose.
Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
While using daptomycin, you may need frequent blood and urine tests.
This medicine can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using daptomycin.
Store daptomycin powder in the refrigerator, do not freeze. After mixing daptomycin with a diluent, store in the refrigerator and use it within 48 hours. Do not freeze.
Mixed medicine must be used within 12 hours if you keep it at room temperature.

What should I avoid while using daptomycin?
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.
