Today, when you get a prescription filled, you simply take your prescription to the pharmacy, where in turn, they give you the correct dosage that you need. This has not always been the case. Nearly a century ago, when a patient needed a prescription filled it was a very different process than it is today. The patient would take the prescription to the pharmacist, where they would have to individually mix the drug with precise measurements of ingredients.
This is called compounding your medications. This is individually formulating your medicine to meet specific health care issues of each patient. Determining a patients individual needs is crucial. Because of this, a close relationship between the patient, physician and the pharmacist is critical.
