Zicam is controversial and the FDA issued a warning about using the product and there was a recall. Check aaaai.org or acaai.org for an allergist in your area, good luck ...Read more

Loratadine is weaker: When loradine (claritin) was studied the manufacturer selected the lowest dose that gave a response better than placebo but didn't have more side effects than placebo. This caused it to be a fairly weakly effective med. As it wasn't studied at higher dose i can't speak to safety of higher doses.

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 Dr Lori Lange ...Read more
Both antihistamines: Both Claritin (loratadine) and zyrtec are antihistamines. Each should last 24 hours for control of allergic rhinitis symptoms.

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
