A member asked:

Why would my pulse be 108 and heart racing after taking claritan d. didn't happen right away--it took about 8 hours.

A doctor has provided 1 answer

Plain Claritin (loratadine): Claritin (loratadine) d contains Pseudoephedrine a sympathimemitic drug. It can cause arrhythmias and hypertension. I suggest to replace Claritin (loratadine) d by Claritin (loratadine) without pseudoephedrine. If symptoms persist see your doctor.
