Can you take Zyrtec in the morning and Xyzal at night?

In this article, we will discuss taking Zyrtec (Cetirizine) in the morning and Xyzal (Levocetirizine) at night – both of which are antihistamines, medicines used to manage allergy symptoms. We will also discuss the potential risks of this treatment approach and some appropriate alternatives to use. 

Can you take Zyrtec in the morning and Xyzal at night?

It is generally not recommended to take Zyrtec and Xyzal at the same time or on the same day unless advised by a healthcare provider. 

Both Zyrtec and Xyzal are second-generation antihistamines and taking either of these meds once a day is enough to help your allergy symptoms unless your doctor tells you otherwise (1,2). 

Zyrtec and Xyzal are closely related antihistamines. In fact, Levocetirizine – the active drug in Xyzal, is essentially a mirror image or enantiomer of Cetirizine, the active drug in Zyrtec, and they work in nearly the exact same way (3). 

Taking them both on the same day doesn’t offer any significant advantages; it’s like taking a higher dose of Zyrtec. This combination may not provide additional benefits for managing allergies, but it does increase the risk of overdose symptoms in some individuals (4). 

If you have concerns about your allergy treatment or need to adjust your regimen, consult your healthcare provider for advice. 

Potential side effects of taking Zyrtec in the morning and Xyzal at night

Taking Zyrtec in the morning and Xyzal at night can cause additive side effects, as one antihistamine is enough for a day. The risk of these side effects becomes higher when these meds are taken in close proximity. 

Commonly expected side effects associated with taking an extra dose of antihistamine include: (4)

  • Nausea
  • Dry mouth
  • Dizziness
  • Sedation
  • Dry eyes
  • Constipation

These side effects can vary from person to person, as each individual is unique and can respond differently to medications. People can also have different factors affecting their health that may also make a difference. 

This is why you should never take two antihistamines unless advised by your healthcare provider. 

What are the alternatives to taking Zyrtec and Xyzal on the same day?

If you’re considering alternatives to taking Zyrtec and Xyzal together, there are options like nasal sprays that can complement antihistamines. One such nasal spray is Flonase (Fluticasone Propionate), which can be taken alongside antihistamines like Zyrtec or Xyzal (5).

Flonase works differently from antihistamines. It’s a corticosteroid nasal spray that helps reduce inflammation in the nasal passages, addressing symptoms like sneezing, runny nose, and congestion. 

Flonase is safe to use in combination with antihistamines like Zyrtec, Claritin, and others. These two types of medications work on different aspects of allergies and can be quite effective when used together.

Moreover, there’s Flonase Sensimist (Fluticasone Furoate) available as well, which is slightly different from Flonase (6). This version contains a gentler form of Fluticasone that is designed to be more comfortable for the nasal passages, minimizing potential irritation.

If you find yourself unsure about which nasal spray to choose or how to best manage your allergies, don’t hesitate to reach out to your pharmacist. he/she can help you choose the one from the various options available that suits your needs.

When to consult your doctor?

If you find these medications ineffective in managing your symptoms, and you still find yourself struggling, please reach out to your healthcare provider. 

Your doctor will properly evaluate your symptoms and will determine the best course of action to restore your health in the best possible way.
