Question 1

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

Accepted 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.

Question 2

does claritan d-12 cause heart palpitations?

Accepted Answer

Palpitations: The decongestant in Claritin (loratadine) d is pseudephedrine. It is known to act like a stimulant in some people that may cause rapid heart rate and palpitations. May cause insomnia as well. Not everyone gets these side effects.

Question 3

can claritin (loratadine) d cause rapid heart rate?

Accepted Answer

Possible: The decongestant can elevate the heart rate.

Question 4

why am i retaining water so much if i don't have kidney or heart issues that i know of? i do take celebrex, silvastatin, benadryl, (diphenhydramine) claritin, which is causi

Accepted Answer

Celebrex (celecoxib): Although less likely than other nsaids in causing sodium retention, Celebrex (celecoxib) is capable of it.  Are you consuming a lot of sodium in your diet?  If so reducing the intake may help.   Some people just tend to retain water for no apparent reason. I hope you are not eating a lot of licorice.

Question 5

can claritin-d cause you to have a rapid heart rate?

Accepted Answer

Not usually: Claritin (loratadine)-d can cause elevated BP in those who already suffer from hypertension.  Claritin (loratadine) can cause arrhythmias (disorders of heart rhythm) and so can the "d" part, pseudoephedrine.  If you have hypertension or heart problems, you should stay away from most decongestants, most people can use antihistamines such as plain Claritin (loratadine) safely however.

Question 6

would using claritin (loratadine) d cause rapid heart rate during exercise?

Accepted Answer

Yes, any "D" drug : The "d" in claritin-d, or Mucinex (guaifenesin) - d and others,  all stand for decongestant.  Decongestants are medications that stimulate the adrenaline system and can cause higher blood pressure and heart rate.  While not bad for short time, may cause problems if used chronically.  Check with your dr. If you have high blood pressure or heart rhythm problems before using these medications.

Question 7

can claritin (loratadine) cause heart palpitation (skip beats).  i started this med six days ago and i had two episode of heart palpitations. ?

Accepted Answer

Not a common effect: Yes, Claritin (loratadine) can cause heart palpitations, it is not one of the common side effects of this medication but it is a complaint I have heard about from my patients.

Question 8

do sinus/allergy pills affect heart rate? after taking claritin (loratadine) d my heart seems to be going crazy! just going from sitting to standing doubles my hr.

Accepted Answer

Yes decongestants: Yes decongestants , such as sudafed will raise heart rate and cause palpitations.  So Claritin (loratadine) d will, but plain Claritin (loratadine) is less likely to.

Question 9

can my 8 yr old child who has heart disease take benadryl (diphenhydramine) and claritin at the same time?

Accepted Answer

Should be fine: The medicatios are helpful in some and do not interfere with each other if used at the same time.I would make sure the kids stomach settles between medications or both together might upset the stomach.

Question 10

doc said stop loratadine b/c thinks is causing fast heart. also on topiramate for migraines. is he right or mixing up with claritin-d's decongestant?

Accepted Answer

Unclear: Loratadine has been reported to cause arrhythmia s as well as tachycardia. Topiramate has no such side effect
I would also stop the claritin (loratadine) d. Do not forget about caffeine which can also do this.
Best wishes.
