Q1. Can I take Zyrtec-D at night?
It may cause sleeplessness due to the pseudoephedrine. Best taken during the day.

Q2. Is it the same as regular Zyrtec?
No. Zyrtec-D contains both cetirizine (antihistamine) and pseudoephedrine (decongestant), while regular Zyrtec only has cetirizine.

Q3. Can I take it with blood pressure medication?
Use with caution. Pseudoephedrine may increase blood pressure – consult your doctor.

Q4. Is Zyrtec-D habit-forming?
No, but it should not be used long-term without medical advice, especially if you have chronic sinus issues or hypertension.
