Every time you donate, you are asked if you have taken certain medications, including Proscar, Avodart, Propecia, Accutane, Soriatane and Tegison.
The reason we ask is simple: These medications can cause birth defects, which is why they never are prescribed for women who are pregnant or are trying to become pregnant. We just want to make sure that any blood you donate is clear of any of these medications, in case one of the patients who receives it is pregnant.
These guidelines have been established by the U.S. Food and Drug Administration and apply to all blood centers in the United States.
If you have taken Proscar, Propecia or Accutane, you can donate one month after your final dose, as a month is enough time to clear them from your bloodstream.
