I get headaches from allergies. Can I take Claritin (loratadine) and zyrtec at the same time? Claritin (loratadine) didn't work alone when I traveled away from home.

Yes, but: Both Claritin (loratadine) and zyrtec (cetirizine) are new generation antihistamines. While there is no harm to using them together, there is likely no added benefit either. The most effective treatment for nasal allergies is the topical nasal steroid sprays such as qnasl, flonase, veramyst, nasonex, (mometasone) etc if a person doesn't have relief with an antihistamine alone. ...Read more

Taking Claritin (loratadine) and zyrtec at the same time?

Not necessary: Both Claritin (loratadine) and zyrtec are considered new generation antihistamines and have the same effects.

Is it bad to take Claritin (loratadine) d for an extended period of time? It's the only med that's worked for my congested nose. Zyrtec didn't help & was on it 1mo.

Decongestant: What you are responding to in Claritin (loratadine) d is the decongestant, but with time it loses effect and may predispose you to high blood pressure. You are better off consulting an allergist and getting proper treatment for your allergies especially that you also use an inhaler, the 2 are probably linked. ...Read more

Hi can I take zyrtec in the morning and claritin at night?

Not the Standard: Hi HPratt,
Not really Zyrtec tablets and Claritin are usually once a day meds. They are 2 different antihistamines. Claritin does come in a 12 hour form. So you would take one in the am and one in the pm.
Certainly you could use both antihistamines but it is not usually the standard of care.
Thanks for your question

Is it possible for me to take zyrtec and claritin (loratadine)?

Both antihistamines: Both Claritin (loratadine) and zyrtec are antihistamines. Each should last 24 hours for control of allergic rhinitis symptoms. However, some patients have more severe symptoms or may be using antihistamines for reasons other than allergic rhinitis and may require more frequent dosing of antihistamines including using Claritin (loratadine) and zyrtec same day. Recommend this be done under allergist supervision. ...Read more

Is it ok to take Claritin (loratadine) in the morning and Zyrtec at night?

No additional benef: Since both of these meds work in very similar ways, there is likely to be very little additional benefit from using both, and much more likely to have side effects from the meds. If one alone is not working, talk to doc about what combination therapy may be more useful, including use of prescription med like Singulair (montelukast). Also need to delve into allergen prevention so you won't need as much meds. ...Read more

Are Claritin (loratadine) and zyrtec the same effectiveness when use for allergic rhinitis?

Are Claritin (loratadine) and zyrtec the same effectiveness when use for allergic rhinitis?

Yes: Claritin (loratadine) and zyrtec are both oral antihistamine agents that block the effects of histamine on what is called the h1 receptor. By doing this, they reduce the release of histamine, a substance that causes itching, runny nose, and sneezing. Zyrtec blocks the receptor a bit better, but the clinical effect of the medications is roughly the same. Zyrtec may cause some drowsiness, but may last longer. ...Read more
