What precautions should be taken before and after as well as at the time of injecting zolindronic acid (5mg) to a stented patient under cardiac meds?

Check with your md: I don't believe that any special pretreatment or precautions are needed for the infusion, but it's always best to check with the attending physician and the prescribing physician before the procedure. In addition,your pharmacist who knows all of the patient's medication, is a valuable source of advice about medication interactions.
