9 Best Flomax Alternatives & Competitors (2026)

UroLift uses permanent nitinol implants to retract prostate lobes and is performed in-office with rapid recovery. It preserves sexual function like Zenflow but the implants are not designed to be removed, limiting reversibility. Pricing is typically procedure-based and insurance-covered, though some patients experience implant encrustation not seen in Zenflow's data.

Rezum delivers water vapor to ablate prostate tissue in an office setting with good symptom relief. Unlike Zenflow's mechanical implant, it permanently removes tissue and often requires catheterization. It is less expensive per procedure but lacks Zenflow's reversibility and has higher rates of temporary sexual side effects.

GreenLight is a laser vaporization procedure performed in hospitals or surgery centers that removes obstructing tissue. It involves general anesthesia and longer recovery than Zenflow's flexible-scope office procedure, with higher risk of sexual side effects and no reversibility option.

Aquablation uses robotic waterjet technology for precise tissue removal under ultrasound guidance. It is effective but requires general anesthesia and operating room resources, unlike Zenflow's flexible office-based delivery, and is not reversible.

iTind temporarily implants a nitinol device to reshape the prostate over several days. It offers short-term relief without permanent implants but requires device removal and shows less long-term durability data than Zenflow's multi-year results.

Proscar is a 5-alpha reductase inhibitor taken daily to shrink the prostate. It has slower onset, sexual side effects in some users, and requires ongoing use, making it less appealing than Zenflow's single-procedure durable relief without medication dependence.

Generic tamsulosin provides affordable daily BPH symptom control but shares the same adherence and side-effect issues as branded alpha blockers. It lacks the long-term efficacy and sexual-function preservation demonstrated in Zenflow trials.

HoLEP removes large amounts of prostate tissue with a laser and is highly effective for large prostates. It involves longer operative time, hospital stay, and higher sexual side-effect risk than Zenflow's gentle, catheter-free outpatient procedure.
