Can we write DR after doing doctor of pharmacy?

The title "DR." is typically used to refer to individuals who have earned a doctoral degree, such as a medical doctor (MD) or a doctor of philosophy (PhD). While a Doctor of Pharmacy (PharmD) is a professional doctorate degree, it does not confer the title of "DR." instead, pharmacists in the United States generally uses the abbreviations "PharmD" after their names to indicate their specialized professional degree.

It's essential to use these titles and professional designations carefully and accurately so as not to misrepresent oneself or one's level of education and expertise.
