How should I use penicillin G potassium (Pfizerpen)?
Use this medication exactly as it was prescribed for you. Do not use the medication in larger amounts, or use it for longer than recommended by your doctor. Follow the instructions on your prescription label.
Penicillin G potassium is given as an injection into a muscle or vein. It may also be injected into the membrane surrounding the lungs. The medicine must be given slowly through an IV infusion, and can take up to 24 hours to complete.
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 this medicine if you do not fully understand how to give the injection and properly dispose of needles, IV tubing, and other items used in giving the medicine.
Do not use the medication if it has changed colors or has any particles in it. Call your doctor for a new prescription.
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.
To be sure this medication is not causing harmful effects, your blood will need to be tested on a regular basis. Your kidney or liver function may also need to be tested. Do not miss any scheduled appointments.
Use this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Penicillin G potassium will not treat a viral infection such as the common cold or flu.
After you have finished your treatment with penicillin G potassium, your doctor may want to do tests to make sure your infection has completely cleared up.
Store the dry powder medicine at room temperature away from moisture and heat.
