Just one other side effect to be aware of should you have an eye operation in the future.
The drug may also affect the muscle that controls the opening and closing of the iris and cause difficulties for the surgeon carrying out the procedure however, if he/she is advised of the fact that Tamsulosin is/has been taken they will be able to take the appropriate action which allows them to proceed.
In my case, long term use of the drug resulted in my developing pinpoint pupils which wasn't much of an issue other than my night vision was slightly impaired.
Other than that I experienced no other side effects.
