Can I Take Allegra And Benadryl
Fexofenadine is an antihistamine which is used to treat allergies such as hayfever, and hives. It can be taken once or twice a day. It is a second generation antihistamine and does not cause as much drowsiness as other antihistamines such as Diphenhydramine (benaryl) or chlorpheniramine. Always be careful about drowsiness with any antihistamine especially if driving ...Read more
Yes, but why: Allegra (fexofenadine) and Benadryl (diphenhydramine) are both antihistamines. Allegra doesn't cross into the brain, so no sedation. Benadryl commonly causes sedation. Typically there is no advantage to taking the 2 together, but also there is no harm at usual doses. ...Read moreSee 1 more doctor answer
Yes: You can take them together. If you are sensitive to the sedating effects of antihistamines, you should not take them at the same time. It would be better to take Allegra in the morning or afternoon and then Benadryl (diphenhydramine) in the evening before bed. However, if you don't feel sleepy after taking antihistamines, it would not be harmful to take them together. ...Read more
Don't take together: All 3 drugs mentioned are antihistamines available w/o prescription. Benadryl (diphenhydramine) is most potent but also most laden w/anticholinergic side effects, eg sedation, dry eyes/mouth, constipation, urinary retention etc. Zyrtec (cetirizine) is more sedating than Claritin (loratadine). Both have less potential side effects than Benadryl but you need to find best for you. Don't take together. ...Read moreSee 2 more doctor answers

Can I take Zyrtec and Claritin together? Or can I take Zyrtec and Benadryl (diphenhydramine) to boost the Zyrtec? Will taking Mucinex DM along with Zyrtec help?
See your doctor: If your allergies are not controlled with one med alone, stepping up to a different med like flonase, nasonex, etc., will likely help you more than taking two antihistamines. Zyrtec and Claritin will not help much at all if you have a cold and not allergies, though Benadryl (diphenhydramine) can dry up secretions somewhat. You can add Mucinex if you also have a cough. Talk with your doctor about your symptoms. ...Read more
