Yes- what symptom?: Allegra d is a combo of fexofenadine and pseudoephedrine. The 12 hour preparation has 120 mg of sudafed in it, a lot of decongestant, if you are sensitive.

I've been taking Allegra D daily for years & it helps a lot with my allergies. Is long term Pseudophedrine use bad? What about developing a tolerance?
Fortunately this product has been around for many years. It is ALWAYS best to stop a medication if you can. Try Breakfast in Bed. Hot tea, etc BEFORE you get out of bed might prevent allergy symptoms.
Personally I prefer nasal type sprays because their effect is limited to nose only, not to entire body. ...Read more
Antihistamine differ: They are not. Both are over the counter antihistamines. The similarity ends there. Allegra d contains Pseudoephedrine as a decongestant and fexofenadine as an antihistamine. Fexofenadine is non-drowsy. Benadryl is also an antihistamine called diphenhydramine. It is also the active ingredient in most otc sleeping pills and can be very sedating. ...Read more

Best to be safe; NO: There are no data on the excretion of fexofenadine into human milk. Pseudoephedrine is excreted into human milk. There are no reports of adverse effects in infants who were exposed to Pseudoephedrine in breast milk. The american academy of pediatrics considers Pseudoephedrine to be compatible with breast-feeding, but Allegra has insufficient studies to prove/disprove safety. Recommend against. ...Read more

Allegra (fexofenadine) 180 mg: Zyrtec may cause drowsiness. Allegra (fexofenadine) does not cross into the brain and should not cause drowsiness. The "d" component is a decongestant and may cause insomnia, decreased appetite, high blood pressure and in men - urinary difficulties due to prostate issues so I do not prefer the Allegra (fexofenadine)-D products.

Yes, but...: 19 yo female taking nasacort, allegra-D and benadryl (diphenhydramine) all together. Yes, it is safe to take these together. For allergies, often a nasal spray and one oral antihistamine improve symptoms greatly. Don't use Allegra-D for more than 3 days at a time, try just regular Allegra. Also benadryl (diphenhydramine) can make you tired and only last a few hours. See allergist if this combo of meds still not helping symptoms ...Read more
