Did I take my Zyrtec?

I don't know whether I took my Zyrtec tonight or not. I have a mitral valve prolapse and high blood pressure (for which I take lisinopril 10 mg.), but I never have had any problem with taking a normal dose of Zyrtec...if I go ahead and take a Zyrtec, and it turns out that I did already take one, would it do any harm?

Hello,
Antihistamines are pretty benign.  I take more than the daily recommended dose per doctor's orders every day.  Unless you are taking Zyrtec-D, which it sounds like you know not to do, it won't be a problem.  I would go ahead and take a plain Zyrtec.

God bless.

Hello,
It depends on the dose of Zyrtec that you are taking. It is available as 5 mg and 10 mg tablets. If you are on 5 mg tablets and plain Zyrtec then you can take one more tablet but if you are taking 10 mg dose, then it is not to be taken again.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. Treatment can be started only when the diagnosis is confirmed. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.

Thanks for your replies.
Since it was so late, I decided to call the pharmacy before they closed (midnight). The pharmacist told me since I was taking the 10 mg, to just skip it that night...I started back the next night on my regular dosage.
Thanks again for your concern, God bless you both!
