What does RFD(S) mean in PRESCRIPTION
RFD stands for reference dose. The reference dose, or RfD, is used to evaluate the potential health risks associated with exposure to a certain chemical. This is done by establishing an amount of the chemical that a person can be exposed to each day over their lifetime without any major health risk.

Essential Questions and Answers on reference dose(s) in "MEDICAL»PRESCRIPTION"
What is a reference dose?
A reference dose (RfD) is a calculated level of exposure to a chemical which poses no significant health risk if a person is exposed to it over their lifetime.
How is the reference dose determined?
The reference dose is determined by examining scientific data related to the toxicity of a specific chemical and then estimating an amount that would pose no major health risk when exposed daily over time.
Can humans be exposed to substances at levels greater than the RfD?
Yes, but it should only be done if there are mitigating factors necessary for ensuring safety for those exposed. For instance, requiring protective gear or limiting exposure times may enable people to safely exceed the RfD without worrying about potential health effects.
Who sets the RfD values?
In the United States, it is generally left up to governmental agencies such as the Environmental Protection Agency (EPA) or Department of Health and Human Services (HHS) who have access to more comprehensive data on chemical safety and toxicity levels than any single organization or industry.
Why are there sometimes different RfD values established by different organizations?
This could be due to different interpretations of data or because different organizations have access to different types of data when establishing RfDs. Therefore, they arrive at slightly different conclusions based on what they know at any given time.
Final Words:
The reference dose plays an important role in assessing human exposure levels for potentially hazardous chemicals; understanding how these doses are determined and interpreted can help protect individuals from unnecessary health risks as well understanding why different organizations may arrive at slightly different RfDs for similar chemicals.
