Can taking Flomax create complications during cataract surgery?

Tamsulosin (Flomax) is an alpha blocker that eases the flow of urine in men with benign prostatic hyperplasia (BPH) by relaxing muscles in the prostate and in the bladder outlet. The medication reduces symptoms in about 70% of men with BPH, and it has very few side effects. Unfortunately, though, it can increase the risk of complications during cataract surgery.

The problem is called intraoperative floppy iris syndrome, or IFIS. In 2005, the FDA issued an advisory about the risk of IFIS during phacoemulsification cataract surgery in men taking tamsulosin; the problem is much less likely with other alpha blockers.

Unfortunately, stopping your tamsulosin may not help, since IFIS has developed in men weeks or even months after they stopped taking the medication. Staying on your medication is good news for your prostate, and there is also good news for your eyes. If your eye surgeon knows you're on an alpha blocker, he can use special surgical techniques that minimize the risk of IFIS.

Since your ophthalmologist and your urologist may not cross paths very often, it's up to you to communicate with both. In fact, you should always inform each of your doctors about all your medications and supplements as well as any drug allergies. List all your medical conditions, even the ones that don't seem relevant to a particular specialist.

Good communication is the key to success. In this case, it means you'll be able to see and to pee.
