Flomax Side Effects

Although most people tolerate Flomax well, there are some potential side effects of the medication. Some of the most common Flomax side effects include abnormal ejaculation, a runny or stuffy nose, and dizziness.

However, there are several side effects of Flomax that you should report to your healthcare right away, including signs of an allergic reaction or a painful erection that will not go away.

Flomax Side Effects: An Introduction

As with any medicine, there are possible side effects associated with Flomax® (tamsulosin hydrochloride). However, not everyone who takes this drug will experience side effects. In fact, most people tolerate Flomax well. When side effects do occur, in most cases they are minor, meaning they require no treatment or are easily treated by you or your healthcare provider.
