Definition: Prophylaxis means preventative, or to prevent. Prophylactic is an adverb and is used to describe, for example: the physician provides prophylactic healthcare.  These words are Greek in origin, from the word "phylax", meaning "to guard" and "watching."

Prophylactic Healthcare

In medicine, the term prophylactic is used to describe surgeries, dental cleanings, vaccines, birth control and many other types of procedures and treatments that prevent something from happening.

A prophylactic hepatitis vaccine prevents the patient from getting hepatitis, while a prophylactic dental cleaning prevents tooth decay.

Types of Prophylactic Care

Preventative care takes many forms, and continues even after a disease process has been identified. Generally speaking, prophylaxis doesn't just mean preventing disease, it can also mean preventing a worsening of disease, minimizing the severity of disease and preventing over treatment.

Primary Prophylaxis: Preventing or increasing resistance to disease that has not occurred.  This may include routine medical checkups and vaccinations.

Secondary Prophylaxis: Early detection and treatment of a disease process.  This would include screenings for common conditions so they may be treated in their early stages, such as a yearly blood pressure and blood glucose check.

Tertiary Prophylaxis: Treatment to decrease the effects or spread of a disease.

This would include surgery to treat a condition, and medications. 

Quaternary Prophylaxis: This is the idea that excessive medical treatment should be prevented, and that patients who will not benefit from further medical treatment should not be subjected to it.

Prophylactic In Common Use

In general conversation, the term prophylactic is often a synonym for condom, as condoms are considered prophylaxis for unwanted pregnancy.
