Key takeaways
Jalyn (dutasteride/tamsulosin) and tamsulosin (Flomax) are both used to treat symptoms of an enlarged prostate (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 adrenergic receptor blocker. This combination works by both stopping the prostate from growing and relaxing the muscles around the bladder and prostate. On the other hand, tamsulosin is a single medication that only relaxes the muscles to improve urine flow. Jalyn can cause more sexual side effects, such as problems with ejaculation and erection, and it may also lower sperm count. Tamsulosin is considered a first-choice treatment for BPH and is less likely to cause a sudden drop in blood pressure compared to Jalyn. Both medications need to be taken 30 minutes after the same meal each day, but Jalyn combines two treatments into one pill, which might be more convenient for some people.
