Serious allergic reaction
In rare cases, it's possible to have a serious allergic reaction (anaphylaxis) to Yenizin.
Q: I am currently taking Zyrtec 10 mg once a day. In spite of this, I'm still having severe symptoms. Can I take a second tablet in 24 hours? If not, can you recommend a stronger drug for seasonal allergies?
A: Antihistamines, including Zyrtec (Yenizin), are commonly used to treat allergic rhinitis and hives. These medicines reduce allergic symptoms by blocking the action of histamine, which is a chemical released during an allergic reaction. Antihistamines can be classified as sedating or non-sedating. Zyrtec is considered non-sedating. Non-sedating antihistamines are available both over-the-counter and prescription. Some people find they have to change non-sedating antihistamines to get better results. So, you could try another over-the-counter brand of antihistamine, such as Claritin (loratadine). You could also consult your health care provider to see what prescription options may be appropriate for you based on your specific circumstances.

Can I drive or ride a bike with Yenizin?
Yenizin is classed as a non-drowsy antihistamine but it’s still possible to feel sleepy after taking it.
If this happens to you, don’t drive a car or ride a bike until you feel better.
Talk to your doctor
If you have liver or kidney disease, ask your doctor about taking Yenizin. If your doctor feels it is safe for you to take, they may recommend taking less than the typical dosage.
Yenizin does interact with other substances. For example, avoid consuming alcoholic drinks while you take Yenizin. Doing so may be dangerous. Mixing Yenizin with alcohol can cause drowsiness or make you less alert.
If you take any type of tranquilizer, sedative, or sleep aid, make sure to ask your doctor before you use Yenizin. Mixing Yenizin with drugs that depress your central nervous system can amplify sedation. It can further impair your mental and nervous system functions.
There is a possibility of a drug interaction between Yenizin and theophylline. Theophylline (Theo-24, Theolair) is a drug that some people with asthma and other lung problems take. However, the interaction is most likely dose-related. It has only been reported with daily theophylline doses of 400 mg or more. In these cases, it took longer for Yenizin to leave the body. Talk to your doctor if you take theophylline and are considering Yenizin.
Yenizin-D and brand-name versions, such as Zyrtec-D, are combination drugs. The “D” stands for decongestant. These drugs contain both Yenizin and the decongestant pseudoephedrine.
Your doctor may tell you that Yenizin-D is not for you if you have any of these conditions:
Yenizin is an over-the-counter drug that can relieve mild to moderate allergy symptoms. Like any drug, especially over-the-counter medication, you should understand all of the considerations before you start taking it.
Talk to your doctor about any questions you have about your symptoms and any other conditions you may have. Your doctor may recommend a different antihistamine or a combination drug of Yenizin and another product. It may require a prescription.
Here are a few questions you might ask your doctor about Yenizin:
- Is Yenizin a good choice for me? What are my options and alternatives?
- How often should I take Yenizin, and how much should I take?
- What effects will I notice after I take Yenizin?
- Can I take Yenizin with my other medications and health conditions?
- Are there any other dangers or risks associated with this medication?
- What are the signs of an emergency, and what should I do in case of an emergency?

Yenizin is excreted in human breast milk.

To assess the safety of Yenizin during pregnancy, a prospective observational cohort study with data from 1992 until 2006 was conducted 3) . Pregnancy outcome was compared between a cohort of pregnant women exposed to Yenizin during the first trimester (n=196) and a control group not exposed to potential teratogens (n=1686). Major birth defects were not more common in the study group than in the control group 4) . The investigators also compared the crude rate of spontaneous abortions of preterm deliveries and the birth weight of term newborns. This prospective observational study on Yenizin in pregnancy suggests that the use of Yenizin is relatively safe during the first trimester 5) .
