What is Cubicin?

Cubicin is an antibiotic that fights bacteria in the body.

Cubicin is used to treat bacterial infections of the skin and underlying tissues, and infections that have entered the bloodstream.

Cubicin is used for complicated infections, including MRSA or "super bug" infections. MRSA stands for methicillin-resistant Staphylococcus aureus.

Call your doctor at once if you have a new or worsening cough, fever, trouble breathing, diarrhea that is watery or bloody, muscle pain or weakness, tingly feeling, fever or flu symptoms, dark colored urine, mouth sores, pain or burning when you urinate, urinating less than usual or not at all, pale skin, or feeling light-headed.

How should I use Cubicin?

Cubicin is given as an infusion into a vein. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.

Read and carefully follow any Instructions for Use provided with your medicine. Do not use Cubicin if you do not understand how to use the injection and properly dispose of used needles, IV tubing, and other items used to inject the medicine. Ask your doctor or pharmacist if you have questions.

Cubicin 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).

Cubicin must be mixed with a liquid (diluent) before using it. Prepare your injection only when you are ready to give it. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.

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.

You may need frequent blood and urine tests.

This medicine may cause false results with certain medical tests. Tell any doctor who treats you that you are using Cubicin.

Use this medicine for the full prescribed length of time, even if your symptoms quickly improve. Some infections must be treated for up to 6 weeks. Skipping doses can increase your risk of infection that is resistant to medication. Daptomycin will not treat a viral infection such as the flu or a common cold.

Each single-use vial (bottle) of Cubicin is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose.

This medicine can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using daptomycin.

Store Cubicin in the refrigerator. Do not freeze. After mixing with a diluent, store in the refrigerator and use it within 48 hours.

You may also store mixed Cubicin vials for up to 12 hours at room temperature.

Each vial (bottle) is for one use only. Throw it away after one use, even if there is still medicine left inside.

Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.
