Citilopram and atenolol , does anybody else take these.

I have been taking citilopram , atenolol and xanax for the last 2 years and recently had my cit upped from 10 to 15 mg. I am on day 11 of the new dose and I am having issues with my heart rate, it seems to be running a little high. I was wondering if I might need to adjust my atenolol to coincide with the new dose of cit. If anyone here has had to do this, please reply. thanks.

its just a adjustment period that is all it will pass
