Is it safe to take 2 10mg Zyrtec (cetirizine) a day in the case that my allergic reaction is worsening as the 1st dose is wearing off? Otherwise, what would be my best option?

Is it safe to take 2 10mg Zyrtec (cetirizine) a day in the case that my allergic reaction is worsening as the 1st dose is wearing off? Otherwise, what would be my best option?

Other options: If by allergic reaction you are referring to allergic rhinitis (hay fever) then you might want to think about adding additional meds to regimen to help control symptoms better. Nasal saline rinses, steroid nasal sprays, and various other OTC preparations can help alleviate allergies in conjunction with Zyrtec. See an allergist for further testing to determine sensitivities. ...Read more

Is it safe to take two zyrtec (cetirizine) a day, one in the morning and one at night?

Is it safe to take two zyrtec (cetirizine) a day, one in the morning and one at night?

Sedation: That dose of zyrtec is going to be very sedating. This defeats the purpose of taking zyrtec instead of benadryl (diphenhydramine). That level of sedation will make you a drowsy --> dangerous driver. Have you tried Loratadine or allegra? Do you use Flonase or something like it? Do you regularly flush your nose with a saline/ baking soda solution? ...Read more

I was prescribed Muscadol for a muscle spasm. Is it safe to take with Zyrtec (cetirizine)? I can't be off Zyrtec (cetirizine) for more than a day. Thanks

I was prescribed Muscadol for a muscle spasm. Is it safe to take with Zyrtec (cetirizine)? I can't be off Zyrtec (cetirizine) for more than a day. Thanks

Likely ok: You should always exercise caution when taking medications like sleeping pills, sedatives, and muscle relaxants like Muscadol with first-generation antihistamines like Benadryl (diphenhydramine). Second-generation antihistamines, like Zyrtec, (cetirizine) are non-sedating and are less likely to interact with these types of medications but you should still proceed carefully. ...Read more

Is it OK to take two (10 MG) Zyrtec per day? It immensely improves my breathing, but I don't want any bad side effects. Thank you.

Too much.: Despite the fact that it helps your breathing, that dose of Zyrtec is technically too much per day. You will need to find a medication that is as effective as the higher (unacceptable) dose of Zyrtec. ...Read more

I have been taking Zyrtec right in the morning since two days. It has removed sneezing etc, but I feel sleepy and lethargic during day. When to take?

Other options: Zyrtec causes some drowsiness in about 10% of the people, although this effect tends to fade out after awhile, fexofenadine has virtually no sedating effect. Nasal steroid would even be more effective for nasal stuffiness without the sedating effect. ...Read more

I have to take daily Zyrtec (cetirizine) (10mg). Liver-wise, is it safe to have one glass of wine on a day when I take this med? Or do I need to avoid any alcohol?

No problem: Although it may potentially have an additive effect to the drowsiness induced by alcohol. Make sure you don't drive after the combination on the first occasion just to make sure. If no problem, you may even try 2 glasses of wine and do the same observation but no more. ...Read more

I take zyrtec for skin allergies. Is it safe to take 2 Zyrtec, or 1 zyrtec, 1 Claritin (loratadine) @ night? I get no relief with 1 zyrtec.

Zyrtec (cetirizine): antihistamine OTC. The maximum recommended dose of Zyrtec (cetirizine) is 10mg per day. The interesting fact that studies have been shown that there is no advantage between 10 mg to the 20 mg dose of Zyrtec (cetirizine). Talk to your dermatologist for more information.

Took 1/2 zyrtec (cetirizine) 5 hours ago. Is it safe to take 1/2 dose nyquil liquigels (1 capsule)?

Not a good idea: Nyquil has an antihistamine, cough suppressant and acetaminophen. You are already taking Cetirizine (zyrttec), so why mix medications? Why not take a whole Cetirizine to begin with? Do you really need the other ingredients? ...Read more

Is it safe to take zyrtec (cetirizine) most days of the year or is there a chance for long term problems with taking it too much? I try to avoid taking medicines.

Zyrtec (cetirizine): Zyrtec is a safe anti-histamine with a relatively good tract record in long term users. But note that all medications have side effects. However, some are willing to take a small and smart risk for a better quality of life. Discuss nasal antihistamines & other non-systemic treatments with your doctor. With immunotherapy, an immunologist may be able to help avert your need for medications. ...Read more

Is it safe to take a zyrtec (cetirizine) and 12 hours later a benedryl?

Antihistamines: They are both antihistamines, so I wouldn't take them together. They both act similarly, so their effect would be too much together. Wait until the zyrtec (cetirizine) wears off, about 24 hours. ...Read more

Is it safe to take both zyrtec and benadryl (diphenhydramine)?

Is it safe to take both zyrtec and benadryl (diphenhydramine)?

Not a good choice: Benadryl (diphenhydramine) is a short acting antihistamine. Zyrtec is a long acting antihistamine. You may overdose if taking both at the same time or taking both in the same day. Consider a better allergy medication if zyrtec is not working well or if you have been taking Benadryl (diphenhydramine) longer than 5 days. ...Read more

Is it safe to take 0.5mg of alprazolam with 0.5mg of zyrtec (cetirizine)?

It depends: You should always check with your physician who knows you and what other drugs you are on, but generally, it is ok to take both zyrtec, (cetirizine) a moderate antihistamine, with alprazolam, or xanax, a short acting anti-anxiety drug. You may have more of a dry mouth with both, and the xanax may be a little more powerful or stay in your system a little longer if taken with some meds, or especially alcohol. ...Read more
