Wycillin is given as an injection into a muscle. Your doctor, nurse, or other healthcare provider will give you this injection. You may be shown how to inject your medicine at home. Do not self-inject  Wycillin if you do not fully understand how to give the injection and properly dispose of used needles and syringes.
Wycillin must be injected slowly into a muscle of the buttock or upper thigh.
Do not inject the medication into a vein or life-threatening side effects could result.
Your Wycillin injections should be given at evenly spaced intervals.
Use this medication for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Wycillin will not treat a viral infection such as the common cold or flu.
Call your doctor if your infection does not improve, or if it gets worse while using Wycillin.
Use each disposable needle only one time. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.
This medication can cause you to have unusual results with certain lab tests, including tests to check for glucose (sugar) in the urine. Tell any doctor who treats you that you are using Wycillin.
After you have finished your treatment with Wycillin, your doctor may want to do tests to make sure your infection has completely cleared up.
Store this medication in the refrigerator. Do not freeze. Do not use the mixed medication if it has changed colors or has any particles in it.
