I Ate Expired Zrytec Can Anything Happen To Me
I accidentally took an expired (18 months ago!) Zyrtec pill. Should I take the correct (unexpired) one nowbad well or should I wait 24 hours?
Wait: Medication can lose it's effectiveness past expiration date, but I would not expect it to not be effective at all; especially if only 18 months expired. It will not be harmful at all that you took an expired zyrtec. It will probably still be almost as effective as it was prior to expiration, so I would just wait and take a new one at your normal time the next day. Hope this helps! ...Read more

Oral fruit-pollen: This is likely due to sensitization to a plant pollen and is called oral allergy syndrome or fruit-pollen allergy. It is not usually associated with throat closure. Avoidance is the best but he must eat it, taking an antihistamine ahead of time may be helpful. No fruit is worth the discomfort of itching. ...Read moreSee 1 more doctor answer
Zyrtec (cetirizine) overdose: The usual dose of zyrtec (cetirizine) is 10mg once a day, not twice. Technically, you are overdosing and i would discourage you from doing that. The symptoms of overdose of zyrtec (cetirizine), as outlined by pfizer, the maker of the drug, include severe drowsiness, irritability, restlessness and nervousness. As an adult, you are much more likely to suffer from severe drowsiness than anything else. ...Read moreSee 1 more doctor answer
Better not: If you have uncontrolled symptoms with either alone, another agent may be needed. Aerius d, (desloratadine and pseudoephedrine combo) should be taken regularly as prescribed to see an effect, zyrtec, (cetirizine) is OTC, the component is similar less the decongestant pseudoephedrine. Check with your doctor, for more comprehensive evaluation see an allergist/immunologist, check aaaai.org or acaai.org for an allergist ...Read more
