Not a common cause: Other than steroids, I am not aware of any common allergy drugs that are associated with the development of gynecomastia. For a list of some medications linked to gynecomastia, go to: http://www.Livestrong.Com/article/175328-drugs-that-could-cause-gynecomastia/.

In addition to steroids, marijuana use and obesity are among the most common causes of gynecomastia.

Many causes: Many causes have been postulated for gynecomastia. Most fall under the category of "cause unknown".
Dr. Tom Pousti
Specializes in Plastic Surgery
Many Causes: Gynecomastia comes from the greek meaning "gyne" meaning woman and  "mastos"  meaning breasts.  it refers to abnormal development of large mammary glands in males. Although there may be many “causes”, most cases are idiopathic (no specific cause). The use of certain medications, drugs, organ dysfunction (kidney or liver), hormonal imbalances etc. May also be causative.
