Is it safe to take another 24-hour zyrtec (cetirizine) antihistamine if there's still about 8 hours left before the previous one wears off?
Follow dosing: It's best to adhere to the dosing recommended. It would be hard to overdo it with the zyrtec (cetirizine), the way you are suggesting, but it begs the question- how well does the rx work, if you want more before the proper dosing interval? I would think you need to talk with your doctor about other options to achieve safe allergy control. Sometimes more than one rx is necessary. ...Read moreSee 1 more doctor answer

I'm looking for a natural antihistamine for seasonal allergies rather than using zyrtec (cetirizine)?
Natural treatments: Natural treatments are medications too. Usually not as well studied or characterized for benefit and safety as those approved by the fda. I don't know of any natural antihistamines per se but butterbur has been reported to have benefits. A very safe alternative to allergy medicine is buffered saline washes. These can be purchased or home made but certain hygienic guidelines should be followed. ...Read moreSee 1 more doctor answer

You may want to keep an epinephrine injection handy, and avoid suspicious foods. Follow up with an allergist, check aaaai. Org 4 an allergist ...Read more

I gave my 8 yr old his zyrtec (cetirizine) this morning he takes 2 teaspoons. & bc he's sick I have him a teaspoon of ceron-dm for his cough. I read that it has an antihistamine in it too. I obviously won't give him more today but is that ok?
Should be: Antihistamines can make a person drowsy as a side-effect. The dose of zyrtec (cetirizine) for age is appropriate for your child. Adding the ceron-dm may just make him drowsy. Just because he is doesn't mean that "some is good, more is better"when giving medications. They will not necessarily make him feel any better than using a single medication and runs the risk of overdosing/other adverse effects. ...Read moreSee 2 more doctor answers

Some people have been drowsy with these medicines as well, but others have not. Best wishes. ...Read more
