OncologyIf You Have Taken Flomax(R), Tell Your Ophthalmologist BEFORE Having Cataract Surgery
The results of a new study reinforce an advisory that patients taking
Flomax(R) (Tamsulosin) to treat prostate enlargement and urinary
problems should inform their ophthalmologist about their use of this
drug before undergoing eye surgery. The advisory was issued by the
American Academy of Ophthalmology (Academy) and the American Society
of Cataract and Refractive Surgery (ASCRS) and updates the advisory
the organizations released in 2006. The new study, published last
month in the Journal of the American Medical Association, found that
the alpha-blocker Flomax increased the risk of certain complications
following cataract surgery.
Advice for patients: Men and Women
Patients who take alpha-blockers or are considering taking
alpha-blockers should be aware that the drugs may increase the
difficulty of cataract surgery.÷ While Flomax is largely prescribed
to men to treat prostate enlargement, some women also take the drug
to treat urinary retention problems. Other alpha-blockers are used to
treat hypertension.
It is important that patients inform their ophthalmologist whether
they are currently taking alpha-blockers, such as Flomax, or did so
in the past. Once informed, the ophthalmologist can anticipate
certain problems and employ different surgical techniques that help
to achieve excellent outcomes. Patients should not decide on their
own to discontinue their prostate/alpha-blocker drugs without
consulting their prescribing physician.
Before being started on an alpha-blocker medication for the first
time, patients who already have cataracts should understand that these
drugs can complicate cataract surgery later on. For this reason, they
may want to discuss the risks and the timing of their operation with
their ophthalmologist performing cataract surgery.
"There are many factors that a prescribing doctor considers in
selecting a medication to treat prostate enlargement," said David F.
Chang, MD, one of the investigators who first identified the effect
that Flomax can have on cataract surgery. "Cataract surgeons can
provide additional counsel about how Flomax might affect an
individual patient"s risk for eye surgery, and whether stopping,
delaying, or avoiding the drug is advisable. In addition, many
ophthalmologists believe that other alpha-blockers pose less surgical
difficulty and risk compared to Flomax."
It is also important to reassure patients already taking Flomax that
they have an excellent prognosis for successful cataract surgery, as
long as their ophthalmologist performing eye surgery is forewarned.
"Even with Flomax, the overall risk of serious cataract surgical
complications is very low, and patients needn"t otherwise avoid or
delay recommended surgery," Dr. Chang said.
Background
Cataracts and prostate enlargement are very common age-related
conditions. A cataract is a progressive clouding of the lens of the
eye and is the most common age-related cause of worsening vision.
Ophthalmologists treat cataracts by surgically removing the cloudy
natural lens and replacing it with a clear artificial lens implant.
