What is ZYRTEC®?
ZYRTEC® is an over-the-counter medicine that provides effective, 24-hour relief of indoor and outdoor allergy symptoms.
What allergy symptoms does ZYRTEC® relieve?
ZYRTEC® relieves your worst allergy symptoms of sneezing, runny nose, itchy, watery eyes, and itchy nose or throat.
Is ZYRTEC® an antihistamine?
Yes. ZYRTEC® contains cetirizine HCl, which is an antihistamine.
What is an antihistamine?
An antihistamine is a drug that blocks the action of histamine—an allergy-causing chemical that’s released by certain cells in the body. Antihistamines are used to treat runny nose, sneezing and other allergy symptoms.
Should I take ZYRTEC® with food?
Your choice. ZYRTEC® can be taken either with or without food.
How fast does ZYRTEC® start working?
ZYRTEC® begins to work at hour 1 on the first day you take it.
How long does ZYRTEC® last?
ZYRTEC® provides 24-hour relief, all day and all night.
Is it okay to take ZYRTEC® over a long period of time?
The ZYRTEC® package label doesn’t state a limit on how long you can take ZYRTEC®. Talk to your doctor if you have any questions, especially if you’re taking other medicines or being treated for any other conditions.
What’s the best time of day to take ZYRTEC®?
Any time of day works. And ZYRTEC® will continue to work for 24 hours.
Do I need a prescription to take ZYRTEC®?
No. Since 2008, ZYRTEC® has been available over the counter, without a prescription.
Is the over-the-counter version of ZYRTEC® the same as the prescription strength?
Yes. Today’s ZYRTEC® has the same exact strength as the version that required a prescription previously.
Can ZYRTEC® make me drowsy?
For information on side effects, please read the ZYRTEC® product label or review the product details on this site.
Can I use ZYRTEC® if it is expired?
No. If your ZYRTEC® has expired, please discard it properly and get a new package. (See next question.)
What is the proper way to dispose of unused or expired ZYRTEC® products?
Do NOT dispose of any ZYRTEC® product by emptying it into your sink, toilet or storm drain. Check to see if your pharmacy or community has a take-back program in which you can drop off your expired or unused medicine for them to dispose for you. Otherwise, place your medicine in an unmarked, sealed container and dispose of the container in your household trash. Visit the FDA website for more information.
Questions about ZYRTEC® Dissolve Tabs
Do dissolve tabs work faster than tablets or liquid gels?
ZYRTEC® Dissolve Tabs provide the same fast relief as ZYRTEC® Tablets and ZYRTEC® Liquid Gels. All ZYRTEC® medicines start working at hour 1 on the first day you take it.
Can I chew or swallow the dissolve tabs? Or do they need to dissolve on my tongue first?
ZYRTEC® Dissolve Tabs are designed to dissolve in your mouth without chewing or drinking water, but it’s perfectly fine to chew or swallow them.
Questions about ZYRTEC-D®
How is ZYRTEC-D® different from ZYRTEC®?
ZYRTEC-D® contains pseudoephedrine, which relieves nasal congestion. So it relieves all the same symptoms as ZYRTEC®, plus it also has a powerful decongestant. For more, see: “What symptoms does ZYRTEC® relieve?”
How does ZYRTEC-D® work on sinus pressure and congestion?
ZYRTEC-D® contains a nasal decongestant that narrows the blood vessels in the nose and sinus region, which shrinks the tissue in that area to allow air and mucus to flow normally.
Why is ZYRTEC-D® located behind the pharmacy counter?
Pseudoephedrine, an active ingredient in some cold, allergy, and sinus products, can be chemically processed into methamphetamine (commonly known as meth). The illegal use of meth had increased, prompting Congress to pass the Combat Methamphetamine Epidemic Act of 2006 (CEMA). The objective of the law is to eliminate the use of pseudoephedrine in the illegal production of meth. By law, products containing pseudoephedrine must now be sold behind the counter and through online retailers who must meet certain requirements.
Note that products containing pseudoephedrine remain available without a prescription in most states.
Questions about Children’s ZYRTEC®
How can I be sure I’m giving my child the proper dose of Children’s ZYRTEC®?
Always follow the instructions that come with Children’s ZYRTEC®. When taking Children’s ZYRTEC® Allergy Syrup, be sure to use the dosing cup that comes in the package. Other items like kitchen teaspoons, droppers or measuring devices that come with other medicines may not be accurate. If you have any questions about treating your child’s allergies, please speak with your doctor.
Can Children’s ZYRTEC® make my child drowsy?
For information on side effects, please read the Children’s ZYRTEC® product label or review the product details on this site.
What’s the difference between Children’s ZYRTEC® Allergy Syrup and Children’s ZYRTEC® Dissolve Tabs?
Children’s ZYRTEC® Allergy Syrup can be taken by kids 2 years and older, whereas Children’s ZYRTEC® Dissolve Tabs is for ages 6 and up.
What’s the difference between ZYRTEC® Dissolve Tabs and Children’s ZYRTEC® Dissolve Tabs?
There is no difference. Both products contain 10mg of cetirizine in the same citrus flavor and can be taken by both adults and children 6 years and older.
General Allergy Questions
How do I know if I have allergies?
If you find yourself sneezing a lot or have a consistently runny or stuffy nose, there’s a good chance you have upper respiratory allergies. Allergies affect more than 50 million people in the United States alone.
What are the common symptoms of upper respiratory allergies?
People with allergies can experience lots of symptoms, including sneezing, runny nose, stuffy nose (nasal congestion), or itchy, watery eyes.
What are outdoor allergies?
If you only develop upper respiratory symptoms at certain times of the year (often spring or fall), you probably have seasonal allergic rhinitis, or outdoor allergies. These allergies can be triggered by trees, grass and weed pollens, or outdoor mold. Learn more about outdoor allergies.
What are indoor allergies?
If you have symptoms all year round, it’s likely perennial allergic rhinitis, or indoor allergies. Common triggers include animal dander (tiny skin flakes or saliva from animals), indoor mold and dust mites. Learn more about indoor allergies.
What can I do to help relieve my outdoor allergies?
In addition to taking ZYRTEC®, you may want to:
- Keep your windows closed and use air conditioning instead
- Stay indoors during peak pollen hours (5 a.m. – 10 a.m.)

What is SmartSource?
SmartSource is an online network of coupons and offers that can help you save money. Just download the coupons you want and print them out to use at your favorite stores.
Why do I need Adobe Reader?
With SmartSource's new print technology, we use Adobe PDF Security. Most people already have Adobe Reader installed, so this makes the transition seamless. And while many programs can open PDF files, SmartSource coupons rely on security technologies unique to Adobe Reader.
You can get Adobe Reader for free here.
Can I print coupons more than once?
You generally get one chance to print your coupons and offers, so make sure your printer is turned on and working when you’re ready to print. But if something goes wrong, you get one more try. Also, if the total number of available offers has been claimed, the offer can expire and may not be printed. This can be the case with popular items.
A Message says I already printed offers that I didn't?
SmartSource coupons usually have a print limit of 2 times on any one computer. If you share a computer with other users, they could have used those prints already. Also, offers can expire if the total number that the manufacturer made available has been met. This can be the case with popular items.

Check to verify that your printer is connected and turned on.
If you were trying to print several coupons, the file size may be exceeding the amount of memory you have available. Try printing a single coupon. If that works, you may not be able to print out all that you want in a single session.
If you share a computer with other people, make sure they did not print the coupon already. Since SmartSource coupons can only be printed up to 2 times on the same computer, you may have exceeded the number of print times.
If you see this message, something has occurred with the coupon file and it is no longer valid. To resolve, visit the page upon which you found the coupons, and generate a new coupon file by clicking "Print."
"No printer connected. Please connect your printer, turn it on, and make sure paper is loaded before trying again"
If you are seeing this message, your computer is having trouble trying to find a printer. Please verify that your printer is connected to your computer (via cable or on the same network) and turned on. For more information, visit your Operating System manufacturer.
