Jalyn is an oral tablet made up two different drugs. The first drug is tamsulosin, which is a 5-alpha-reductase inhibitor, and the second drug is called dutasteride, which is considered an alpha-blocker. Jalyn is sometimes referred to as Combodart and is available for purchase in both the brand choice and generic alternative in 0.5mg/0.4mg.

Jalyn is prescribed to men to help treat symptoms of an enlarged prostate; this is medically referred to as benign prostatic hyperplasia/BPH. Symptoms of an enlarged prostate (BPH) includes trouble with urination, a weak urine stream, and still feeling like you need to urinate after urinating. Leaving this condition untreated can lead to serious complications; it will not induce prostate cancer however it may cause urinary tract infections, stones in the bladder or kidney, urinary retention and kidney damage.

Jalyn is effective for the treatment of benign prostatic hyperplasia because of the 5-alpha-reductase inhibitor and the alpha-blocker. The 5-alpha-reductase inhibitor (tamsulosin) helps by reducing the size of the prostate while the alpha-blocker (dutasteride) relaxes the muscles associated with the bladder and prostate. By doing this, the symptoms of BPH will disappear.
