How to Use

The method of administration depends on the specific brand of Pennicilin G you are using. Typically, the medicine is injected into the vein or muscle. It should be used precisely as prescribed as the recommended dose is normally based on your response to therapy and medical condition. In children, dosage is based on weight.

If you are self-administering, take time to understand how to prepare and use the instructions given by the doctor. Always check the product for discoloration or particles before use. If any of these is present, discard the liquid. Seek help from your doctor on how to properly store and discard the medicine.

Antibiotics will work best when the amount of the medicine in the body is kept at a constant level. You should take the dose at the same time each day and never take a larger or smaller dose than recommended. Do not stop using the medicine before the prescribed amount is completely finished. Continue using even if the symptoms disappear. Discontinuing the use of the medicine too early can lead to reinfections.

Let your doctor know if your symptoms worsen or if you experience adverse side effects.
