Common Questions about Lisinopril (Prinivil, Zestril)


Why does the purchase of certain cetirizine products require a valid form of identification?

The main difference between cetirizine and cetirizine D is that cetirizine D or Zyrtec D contains pseudoephedrine as an active ingredient. Because of the use of pseudoephedrine in the manufacture of illegal drugs, the Combat Methamphetamine Epidemic Act of 2005 was signed into law to regulate over-the-counter retail sales of pseudoephedrine.



What is the best time to take cetirizine?

You can take cetirizine at any time during the day. However, if it makes you drowsy, it is best to take cetirizine at night. 



Can I take cetirizine every day?

It is safe to take cetirizine daily if you have allergy symptoms every day. However, you can also take it as needed when your allergy symptoms appear. 



What is the amount of liquid cetirizine I can give my two years old child for allergy?

Usually, children’s cetirizine or Zyrtec comes in a 1 mg / 1 mL or 5 mg / 5 mL solution. The usual starting dose for two years old to treat hives or allergies is 2.5 mg once daily. 2.5 mL of this solution will give you a 2.5 mg dose. Talk to your pharmacist if you have any questions about cetirizine oral doses. 



Can I cut the cetirizine 10 mg tablet?

Cetirizine tablets are not recommended to be cut because they have not been tested to show that each side contains the same amount of medicine. However, the regular tablets and chewable tablets are available in 5 mg.
