Why this happens
Tamsulosin works by relaxing muscles in the prostate and bladder neck, but it can also relax blood vessels, leading to lower blood pressure. Mirabegron can occasionally affect blood pressure and heart rate. When used together, the combined effect on your circulation may increase the risk of feeling dizzy.
What you should do
You can take these medicines together, but be careful when moving from a lying or sitting position to standing. If you feel dizzy, sit or lie down until the feeling passes. It is a good idea to monitor your blood pressure regularly. If you experience severe dizziness, fainting, or a very fast heartbeat, contact your doctor.

Bisoprolol and Trimbow (which contains formoterol) work in opposite ways on the airways. Bisoprolol may cause the airways to narrow, making it harder to breathe and potentially triggering asthma or COPD symptoms. It also makes the formoterol in the Trimbow inhaler less effective at opening your airways.
