Re: Any Doctors/Nurses on here now?!!?!?
I'm not a doctor or nurse, but you can call a pharmacist (or 2 for a second opinion). They know the drugs and reactions better than anyone. Of course go to the ER if you are really worried.
Good luck, I hope you feel better.

Re: Any Doctors/Nurses on here now?!!?!?
My fiance is a doctor..... He said that the palpitations are likely due to the psuedoephedrine in the drugs you took not the antihistamine effect (If it was allegra D or Zyrtec D they have psuedoephedrine) It is a side effect of the psuedoephedrine component of the medication which can cause transient hypertension and tachycardia . Also if they were 24 or 12 hour preparations you possibly might have elevated levels of the drug in your system.. Not to be alarmed tho taking only 2 of these pills in that time frame should not have detrimental affect bc they have large safety window... That being said if you experience worsening of the symptoms or chest pain (VERY UNLIKELY) you should go to the ER
