Are there any new, more effective allergy meds than zyrtec, claratin, allegra (fexofenadine)...etc.?

Are there any new, more effective allergy meds than zyrtec, claratin, allegra (fexofenadine)...etc.?

Allergies - hayfever: Everyone is unique and that includes the distribution of histamine receptors that we all have. Thus some anti-histamines work well for some people while other meds don't. It's a matter of finding the right antihistamine for u. Older meds like Benadryl (diphenhydramine) might actually be worth a try. Seeing an allergist would be best as there are new meds just coming out now for allergies (grastek, oralair, Ragwitek ...Read more

Is name brand Adderall (dextroamphetamine and racemic amphetamine) XR better than the generic brands? I'm reading horror stories online about the generic brands.

Is name brand Adderall (dextroamphetamine and racemic amphetamine) XR better than the generic brands? I'm reading horror stories online about the generic brands.

Generic vs. brand: While generics are claimed to be the exact equivalent as brand name medications, individuals may respond better to trade name medications. However most patients tolerate the generics without problem. Since the generics are less expensive and usually have a lower co-pay, i would try it once. If it does not work as well as the brand, it will not take long to make that determination. ...Read more

Please tell any over-the-counter syrup available for kids having pseudoephedrine hydrochloride, chlorphenamine maleate, acetaminophen?

Please tell any over-the-counter syrup available for kids having 
pseudoephedrine hydrochloride, chlorphenamine maleate, acetaminophen?

I do not think so: If you are asking for a single medication that is available otc with all 3 ingredients, I am not aware of any. You can find some that have the Pseudoephedrine and the chlorpheniramine but not the acetaminophen. I believe advil (ibuprofen) allergy sinus is close having Ibuprofen instead of the Acetaminophen in pill form. That said, cold medications are not recommended for children less than 4 years of age. ...Read more
