Anyone else...? Smelly urine

Have been on Ven for just under two weeks.

I started on 37.5 XR daily and after 7 days moved up to 75 XR daily.

Almost immediately after taking the first tablet, I noticed that my urine smelt of fish... As the day progressed it got better. I put it down to a reaction internally. And thought no more of it.

The same happened again when I titrated up to 75 XR daily. The hours following the increase, the smell returned.

I can't seem to find anything at all listed online in relation to this odd reaction? I know it's not an STI because it has been a while...? And I have no other symptoms or indications.

Has anyone else noticed this or experienced this before?
