About JALYN® (dutasteride and tamsulosin hydrochloride capsule)

JALYN® is a combination treatment is used to treat benign prostatic hyperplasia (BPH) in men with an enlarged prostate.

JALYN® contains a combination of dutasteride and tamsulosin. Dutasteride prevents testosterone from converting to dihydrotestosterone (DHT) in the body. DHT is involved in the development of benign prostatic hyperplasia (BPH). Tamsulosin relaxes the muscles in the prostate and bladder neck, making it easier to urinate.


JALYN® should never be handled or taken by a woman, a child, or a teenager. Dutasteride can be absorbed through the skin. This medication can cause birth defects if a woman is exposed to it during pregnancy. The capsules should not be handled by a woman who is pregnant or who may become pregnant. If a woman accidentally comes into contact with the medication from a leaking capsule, wash the area with soap and water right away. Do not donate blood while taking JALYN® and for at least 6 months after your treatment ends. Dutasteride can be carried in the blood and could cause birth defects if a pregnant women receives a transfusion with blood that contains dutasteride.
