No, the antihistamine in DayQuil and Zyrtec is not the same. DayQuil typically contains phenylephrine as a decongestant and may include other ingredients but does not have an antihistamine. Zyrtec, on the other hand, contains cetirizine, which is a specific antihistamine used to relieve allergy symptoms. Thus, they serve different purposes and contain different active ingredients.

Can you take Hydroxyzine and Dayquil together?

Nope. You're taking two different pain relievers in the Motrin and the DayQuil and two different allergy medicines in Zyrtec and DayQuil. If you have a cold, take DayQuil by itself. If you have allergies and pain, take Zyrtec and Motrin.


Can you take Zyrtec and diphenhydramine?

No, you don't want to take two of the same medications. If the Zyrtec is not taking care of your allergies, don't take a second antihistamine on top of it. You need to switch from Zyrtec to some other antihistamine. It might be time to see your doctor and try a stronger antihistamine. Taking too much antihistamine can cause breathing difficulty.

Is Zyrtec an antihistamine?

Zyrtec (cetirizine) is classified as a second generation antihistamine. It is believed to antagonize peripheral H1 receptors and not cross the blood brain barrier (this is why it is less drowsy then other antihistamines). The side effects of Zyrtec such as dry mouth may suggest that it does have some anticholinergic properties.


Can you take Tylenol and Zyrtec?

Yes, if it is just plain Tylenol with just plain Zyrtec, then there are no serious interactions. If it is a Tylenol cold formula, then you need to read the box. Most of the Tylenol cold products have some combination of antitussive, decongestant, antihistamine and acetaminophen. Please check your container for the ingredients. If there is an antihistamine (usually chlorpheniramine or diphenhydramine), then do not take the Zyrtec (cetirizine) which is an antihistamine.


How much alcohol does Dayquil have?

Can you take Diphenhydramine HCL and dayquil together?

Can you take Zyrtec and Tylenol PM together?

Because they both contain antihistamines, they will cause a reaction. Tylenol PM has the same antihistamine as Benadryl and it is not recommended that you take Zyrtec and Benadryl at the same time. Contact you doctor to verify if you can take your Zyertec in the morning (as usually prescribed) and the Tylenol in the evening. Zertec is a long acting antihistamine and should be out of your system before you go to bed. The Tylenol PM is a short acting antihistamine and would be out your system before your morning dosage.


Who is the manufacturer of Zyrtec?
