Quick Facts
What Is Doubluts Used For?
Doubluts is a medication that combines dutasteride and tamsulosin hydrochloride, used primarily to treat benign prostatic hyperplasia (BPH) in men.
Primary Uses
It is used to alleviate symptoms associated with BPH, such as difficulty starting urination, weak urinary stream, frequent urination, and the sensation of incomplete bladder emptying.
How It Works
Dutasteride reduces the production of dihydrotestosterone (DHT), leading to a reduction in prostate size, while tamsulosin relaxes the smooth muscles in the prostate to facilitate easier urination.
Good to know: Doubluts is not addictive.
