## What is Synercid?

## How is Synercid given?

Synercid is injected into a vein through an IV, sometimes with an infusion pump or through a central IV or "PICC" line.

This medicine is most often given in a hospital setting. However, 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.

Synercid must be given slowly, and the infusion can take at least 1 hour to complete.

Call your doctor at once if you have problems with your IV, or if the medicine does not flow freely from the IV bag through the tubing.

Synercid is usually given for at least 7 days. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Use this medicine for the full prescribed length of time. 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. Synercid will not treat a viral infection such as the flu or a common cold.

If you keep this medicine at home, store the IV bag a refrigerator and use it before the expiration date on medicine label. Do not freeze.
