How is penicillin G sodium given?
Penicillin G sodium is injected into a muscle or into a vein through an IV. You may be shown how to use an injection at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles, IV tubing, and other items used to inject the medicine.
Penicillin G sodium is a powder medicine that must be mixed with a liquid (diluent) before using it. Shake the mixture well before you measure a dose. If you are using the injections at home, be sure you understand how to properly mix and store the medicine.
Prepare your dose only when you are ready to give yourself an injection. Do not use penicillin G sodium if it has changed colors or has particles in it. Call your pharmacist for new medication.
Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Some infections may need to be treated for several weeks. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Penicillin G sodium will not treat a viral infection such as the flu or a common cold.
If you use penicillin G sodium long-term, your blood may need to be tested to make sure the medicine is not causing harmful effects. Your kidney or liver function may also need to be tested.
Penicillin G sodium can cause false results with certain lab tests for glucose (sugar) in the urine. Tell any doctor who treats you that you are using penicillin G sodium.
After you have finished your treatment with penicillin G sodium, your doctor may want to do tests to make sure your infection has completely cleared up.
Store the powder medicine at room temperature away from moisture and heat.
After mixing penicillin G sodium with a diluent, store in the refrigerator and use it within 3 days. Do not freeze.
