If you or someone in your family has experienced a serious side effect to a health product, you are encouraged to report the experience to your health care professional (e.g. physician, pharmacist). You could also complete a copy of the side effect reporting form or report your side effect to FDA.

Side effects reports are analyzed to discover potential health product safety signals. Some important reactions may take an extremely long time to develop or occur infrequently. Continued monitoring of adverse reactions is thus essential to maintain a comprehensive safety and effectiveness profile of health products.

Tamsulosin Side Effects Reported to FDA

The following Tamsulosin reports list potential signals of serious risks and new safety information that were identified using the FDA Adverse Event Reporting System (FAERS).
FAERS is a database that contains information on adverse event and medication errors reports submitted to FDA by healthcare professionals (such as physicians, pharmacists, nurses and others), consumers (such as patients, family members, layers and others) and manufacturers.


The appearance of Tamsulosin on this list does not mean that FDA has concluded that the drug has the listed risk. It means that FDA has identified a potential safety issue, but it does not mean that FDA has found a causal relationship between the drug and the listed risk.

    Flomax (tamsulosin HCl)

    Audience: Ophthalmologists, Urologists, and other healthcare professionals

    [Posted 11/22/2005] Boehringer Ingelheim and FDA notified healthcare professionals of revisions to PRECAUTIONS and ADVERSE REACTIONS sections of the prescribing information for Flomax, indicated for the treatment of the signs and symptoms of benign prostatic hyperplasia (BPH). A surgical condition termed Intraoperative Floppy Iris Syndrome (IFIS) has been observed during phacoemulsification cataract surgery in some patients treated with alpha-1 blockers including Flomax. Most of these reports were in patients taking the alpha-1 blocker when IFIS occurred, but in some cases alpha-1 blocker had been stopped prior to surgery. It is recommended that male patients being considered for cataract surgery, as part of their medical history, be specifically questioned to ascertain whether they have taken Flomax or other alpha-1 blockers. If so, the patient's ophthalmologist should be prepared for possible modifications to their surgical technique that may be warranted should IFIS be observed during the procedure.
