Yes, but it wasn't as substantial as I expected unless it's 7.5mg or more. But that might be me personally.
And I get visual effects from Iva even at standard dose of 5mg - hard to explain but it's like someone's turned the brightness up and my whole vision has a slight light-grey tint over it. Like when you turn the brightness high on a TV and don't adjust anything else and you can see the filter it provides. I can tolerate it but prefer not to. No cardio sides as long as it's dosed 12hrs apart.
Nebivolol 10mg and 5mg Ivabradine together usually get 95 down to 82 for me. If I nudge iva to 7.5mg it goes to around 72-75ish.
To really get it to shift, I needed Diltiazem 90mg alongside them. That not only reduces HR itself, but slows the metabolism of Ivabradine down so that any given dose is around 20% more (it affects the enzymes that metabolise it so it hangs around longer). Of couse, you can also just dose Iva to 7.5mg, but I found the 3 meds had less sides and greater effect.
That combination got me to 62-65bpm, so you can see the trio has a much stronger effect. Of course, you have to watch BP because both Nebi and Dilt impact it. So if BP becomes too low, you just use Nebi and iva, and dose the iva where necessary for personal response.
