I would advise against using this antibiotic if it was formulated over a month ago.
If there is an an Expiry Date indicated on the bottle then that would tell you if the medicine is good for use.
Taking a sortened course of antibiotics would make the infection stronger and resistant to the medicine.
Please talk to your doctor and let him know about your plans to take this, as having an Antibiotic without the knowledge of your doctor can cause complications taht your doctor would find hard to diagnose later on.
