Can I Take Claritin And Zyrtec At The Same Time
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

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

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
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.
