Compare Jalyn vs. Hytrin

Jalyn (dutasteride/tamsulosin) and terazosin are both used to treat symptoms of an enlarged prostate (benign prostatic hyperplasia or BPH), but they have some key differences. Jalyn is a combination of two medications: dutasteride, a 5-alpha reductase inhibitor, and tamsulosin, an alpha-1 blocker. Terazosin, on the other hand, is a single medication that is an alpha-1 blocker. Jalyn works by both reducing the hormone that causes prostate growth and relaxing the muscles around the bladder and prostate, while terazosin only relaxes these muscles. Terazosin can also be used to treat high blood pressure, but it’s not a first-choice option due to side effects like dizziness. Jalyn is taken once a day after the same meal, whereas terazosin is typically taken once daily at bedtime. Both medications can cause dizziness, but Jalyn is more likely to cause sexual side effects, such as problems with ejaculation and erection. Both medications are available in lower-cost generic forms.
