Your symptoms are almost certainly being generated by anxiety, though there may be a small possibility you're reacting to another ingredient, a colour, die lubricant, filler, etc. However, these are fairly standard these days so you have probably been exposed to them before.
Who makes the new tablets and what were you taking before?
PS: Citalopram i also absorbed fairly slowly taking about 4 hours to reach peak plasma levels. How soon after taking the dose did the symptoms begin?
