What's your clinical experience?

I'm looking for input from psychiatrists. I don't want to use stimulant medications for ADHD. I started atomoxetine, but after a few days I developed urinary retention, so my doctor stopped the medication. My question is: is it reasonable to consider adding tamsulosin and retrying atomoxetine under medical supervision? Is this an approach that's ever used in clinical practice? Does tamsulosin usually help with atomoxetine-induced urinary retention? Would tamsulosin be expected to reduce atomoxetine's effectiveness for ADHD? Are there any important risks or reasons this combination should generally be avoided? I'm not looking for personal medical advice—just interested in how psychiatrists think about this situation in practice.
