Can I take Flecainide and Tamsulosin together?

Why this happens

Both drugs are processed by the same enzyme in the liver (CYP2D6). Flecainide can slow down this enzyme, which prevents tamsulosin from being broken down as quickly as usual, leading to higher levels of the drug in your system.

What you should do

You can take these medicines together, but you should be cautious. Monitor your blood pressure and watch for signs of dizziness, especially when moving from a sitting or lying position to standing. If you feel very dizzy or faint, contact your doctor, as they may need to adjust your tamsulosin dose.
